Single Pallet Fiber Laser Cutting Machine – Open Type Bed, 1.5 kW to 20 kW
A single pallet laser cutting machine is a fiber laser cutting machine with one working bed, open on all sides, with the cutting head travelling on a CNC-controlled gantry over sheet or plate loaded directly onto that bed. It is the most straightforward configuration in the range and the most flexible one on the floor: nothing encloses the bed, so stock can be craned in from above, oversized and awkward material is not fighting a door opening, and there is one moving bed system rather than two. Sigma Mechotronics Pvt. Ltd. manufactures it from 1.5 kW to 20 kW, on six standard bed sizes from 3200 x 1600 mm up to 6500 x 2500 mm, with custom bed sizes built to a customer’s drawing. This page covers what the open single bed gives you, how to size it, how to select power, and what to check before you order.

The single pallet machine is where most Indian fabricators start with fiber laser cutting, and it is also where a great many of them stay, because for mixed job work the open bed is genuinely the most practical arrangement. A job shop rarely runs the same part twice in a week. Sheet sizes change, thicknesses change, some jobs arrive as off-cuts and some as full plate, and occasionally something arrives that is nobody’s standard size at all. An open bed takes all of it, because there is nothing between the crane and the material.
It is also the simplest machine in the range mechanically. One bed, one loading position, no pallet-changer drive, no shuttle guides, no enclosure interlocks. Fewer systems means fewer things to schedule maintenance around and fewer things that can stop the machine, which matters most in shops without a dedicated maintenance engineer on site.
Sigma Mechotronics Pvt. Ltd. manufactures this machine at its own plant in Ahmedabad, so the bed size and the power are specified around your work rather than pulled from a fixed catalogue. This page is written for engineers and owners specifying a single pallet machine for production use: what the open bed changes in practice, how to size it against your largest job, when a custom bed is worth building, how to select power between 1.5 kW and 20 kW, and what to get right before the machine arrives.
At a Glance
Key Takeaways
The essentials, before the detail below.
One Open Bed, Crane Loadable
Nothing encloses the working area, so sheet and plate can be lowered straight onto the bed from above – including stock that is oversized or an awkward shape.
Built for Mixed Job Work
Where part sizes, materials and thicknesses change from job to job, the open bed handles the variety without a setup fighting the machine.
1.5 kW to 20 kW
The full power band is available. Bed size does not restrict which laser source you can specify, and neither does the body type.
Six Standard Beds, Plus Custom
3200×1600, 4000×2000, 6000×2000, 6300×2000, 6500×2000 and 6500×2500 mm, with custom bed sizes manufactured to a customer’s drawing.
Mechanically the Simplest
One bed and one loading position means fewer moving systems to maintain than any other configuration in the cutting range.
Plan the Safety Zone
An open bed does not contain the beam in a housing, so the working area needs a demarcated, guarded safety zone. Budget the floor space for it.
Definition
What Is a Single Pallet Laser Cutting Machine?
A single pallet laser cutting machine is a flat-bed fiber laser cutting machine with one fixed working bed, open on all sides rather than enclosed in a cabin. Sheet or plate is loaded directly onto that bed, the CNC-controlled gantry carries the cutting head along the programmed path, and the operator unloads finished parts and the skeleton from the same bed before the next sheet goes on. It is also called an open type single bed or single table machine – the same configuration under three names.
The cutting process itself is identical to every other flat-bed machine in the range: the same fiber laser source across the 1.5 kW to 20 kW band, the same cutting head and assist-gas system, the same six bed sizes, and the same materials – mild and carbon steel, stainless steel and aluminium sheet and plate, with titanium, brass and copper cut where the head is rated for reflective material. Typical output is the full spread of flat fabrication work: structural brackets, mounting and base plates, machine frames, panel and enclosure blanks, gears, discs, gaskets and profile-cut components.
What defines this configuration is what is absent. There is no enclosure, so there is no door opening deciding what fits and no cabin to work around when a crane brings in a full plate. There is no second pallet, so there is no shuttle mechanism, no swap sequence and no travel clearance to reserve at the loading end. That absence is the point: it produces a machine that is easier to place in a building, easier to load with unpredictable stock, and simpler to keep running.
What the Open Single Bed Gives You
01
Overhead Loading
Stock is craned or lifted straight down onto the bed from any side, rather than fed in through a fixed opening.
02
Awkward Stock Accepted
Off-cuts, non-standard sheet and material that overhangs the bed edge are all workable, because nothing physically confines the bed.
03
Fewer Moving Systems
No pallet-changer drive, guides or position sensors, and no enclosure interlocks – less to schedule, service and troubleshoot.
04
Full Access to the Bed
Unrestricted reach from every side makes part picking, skeleton removal and slat cleaning quicker and easier on the operator.
Where It Fits
The Work the Single Pallet Machine Is Built For
This configuration is specified by shops whose incoming work is varied rather than uniform. Here is what that looks like in practice, and what the open single bed does for each case.
| Your Work Profile | What the Open Single Bed Does For It |
|---|---|
| General job work and mixed-batch fabrication | Every job can be set up its own way. Sheet size, thickness and material change freely because nothing about the loading arrangement is fixed. |
| Large, heavy or crane-handled plate | Plate comes down onto the bed from overhead. There is no door width, cabin height or shuttle travel to work within. |
| Off-cuts and remnant nesting | Odd remnants are easy to place, square up and cut, which is how a job shop keeps material cost down across small orders. |
| Long cutting cycles on thick plate | When one program runs long, load and unload comfortably finish inside the cycle anyway – the simpler machine loses nothing here. |
| First fiber laser in the shop | The fewest systems to learn and maintain, and the most forgiving machine to place while your team builds up laser cutting experience. |
A practical note on throughput – on a single bed, the laser is idle while the sheet is changed, so how much that costs you depends on your programs. Time a full sheet change against a typical program run: on long cycles it disappears into the cut, and on short repeat programs it becomes the number worth managing – with good nesting, staged stock beside the machine and a trained loading routine. Tell us your programs and sheet changes per shift and we will work through it with you before you specify.
Standard & Custom
Bed Sizes: Six Standard Options, Plus Custom Beds Built to Order
Sigma Mechotronics Pvt. Ltd. manufactures the single pallet machine in six standard bed sizes and also builds custom bed sizes to a customer’s drawing. Bed size is the specification most often got wrong, because buyers size the machine for the job they run every day rather than the largest job they have to accept.
Standard Bed Sizes
| Bed Size (mm) | Typically Suits | Practical Note |
|---|---|---|
| 3200 x 1600 | Smaller job work, panel and enclosure fabrication, workshops with limited floor area | The compact option, and the easiest to fit a proper safety zone around in a tight bay. Takes the widely used 3000 x 1500 mm plate format with margin. |
| 4000 x 2000 | General sheet metal fabrication – the most common all-round choice | Takes standard 4 ft x 8 ft sheet comfortably and covers most everyday job work without oversizing the machine or the floor space. |
| 6000 x 2000 | Long structural parts, ducting, chassis rails, larger panel work | The entry point into 6 metre work. Suits shops whose length requirement runs well ahead of their width requirement. |
| 6300 x 2000 | 6 metre stock where end clamping or nesting margin is tight | The extra 300 mm of length is working margin, not extra capacity – useful when your parts genuinely run the full 6 metres. |
| 6500 x 2000 | Long-format work with generous nesting allowance | More length again at the same 2000 mm width. Chosen where sheet is fed long and nested tightly to keep scrap down. |
| 6500 x 2500 | Heavy fabrication, wide plate, the largest work in the standard range | The maximum standard bed. Specify it where your width requirement genuinely exceeds 2000 mm, and plan the crane access to match. |
How to read this table – the bed dimension is the machine’s working envelope, not a sheet size. Your usable cutting area is the bed minus the clamping, edge margin and nesting allowance your parts need. Size against your largest regular job rather than your average one – a machine sized for typical work becomes a bottleneck the first time an oversized order arrives, and the bed is the one thing you cannot upgrade later.
Custom Bed Sizes
Where none of the six standard beds suits the work or the building, Sigma Mechotronics Pvt. Ltd. manufactures the single pallet machine to a customer-specified bed size. This is a build-to-drawing job rather than a catalogue variant, so the specification is agreed before manufacture.
| When a Custom Bed Is Justified | Why the Standard Range Falls Short |
|---|---|
| Your part length or width sits between two standard sizes | Stepping up a full size buys capacity you never use and pays for it in floor area and machine cost for the machine’s whole life. |
| The building, not the work, sets the limit | Bay width, column spacing, shutter opening or crane path can rule out a standard footprint even when the bed size itself would be right. |
| The machine has to sit in an existing line or layout | Where fixed equipment, material racking or a press brake position dictates the flow, the bed has to match that flow rather than the reverse. |
| You cut one dominant sheet or blank format at volume | A bed sized around one repeating format cuts nesting waste and handling time on every sheet, which compounds over the machine’s life. |
What to send us for a custom bed – your largest and smallest regular part dimensions, your typical incoming sheet or plate size, material and thickness range, and a shop-floor drawing showing available space including crane access and room for the safety zone. That is enough for our engineering team to confirm whether a standard bed already covers you or a custom build is genuinely warranted.
1.5 kW to 20 kW
How to Select Laser Power
Power is decided by material, thickness and the cutting speed you need – not by bed size and not by budget. Body type has no bearing on power selection: the same 1.5 kW to 20 kW range is available on the single pallet configuration as on our other flat-bed machines.
| Power Band | Generally Suits | Where It Struggles |
|---|---|---|
| 1.5 kW – 3 kW | Thin to medium gauge sheet, panel and enclosure work, lower-volume job shops | Thick plate, and any job where cycle time on medium plate is the bottleneck |
| 4 kW – 8 kW | The broad production middle – mixed sheet and medium plate at commercial speed | Heavy structural plate at high throughput |
| 10 kW – 20 kW | Thick plate, structural steel and high-speed thick-section cutting at volume | Nothing capability-wise – it is capital and running cost, so buy it where thickness or throughput demands it |
Power is also the specification that has to account for what the installation around the machine can support – connected electrical load, chiller and cooling capacity, assist gas consumption and supply arrangement, and extraction sizing all scale with the laser source you choose. Our engineering team works through those points with you before quoting, so the machine that arrives suits the plant it has to run in.
Expert note on assist gas and reflective metals – oxygen gives the most economical cut on mild steel, nitrogen gives a clean, oxide-free edge on stainless steel and aluminium at higher gas cost, and compressed air suits thinner gauge work. Aluminium, brass and copper are highly reflective at the fiber wavelength, so confirm your cutting head is back-reflection protected before running these regularly. Exact cutting thickness and speed depend on material grade, gas and configuration – treat the table above as a starting reference and ask us for a material-specific recommendation.
The Range
How This Machine Sits Against Our Other Cutting Configurations
The Sigma Mechotronics Pvt. Ltd. fiber laser cutting machine range shares the same power band across configurations. What separates them is body type, automation and the stock format each one is built to hold.
| Configuration | Body & Automation | Built For |
|---|---|---|
| Single Pallet | Open type, one bed, manual load/unload | Mixed job work, crane-loaded and awkward stock, the simplest machine to run |
| Auto Pallet Changer | Open type, two beds, automatic pallet swap | Repeat-batch and volume production where machine utilisation drives cost per part |
| Close Body | Fully enclosed cabin, manual load/unload | Shared floors where beam and fume containment are the priority |
| Flat Bed + Pipe Attachment | Flat bed with tube and pipe cutting attachment | Flat sheet plus occasional to moderate tube and pipe work on one machine |
| Dedicated Tube Cutting | Chuck-fed, for 3 metre and 6 metre lengths | Volume tube, pipe and profile fabrication – this one does not cut flat sheet |
Four Checks
How to Specify the Right Single Pallet Machine
Work through these in order. Each narrows the specification, and taking them out of order is how buyers end up with a machine that fits the brochure but not the floor.
- 1
Size the Bed Against Your Largest Regular Job
Not your average job. Leave margin for clamping and nesting, and check the size against the largest order you would want to accept rather than the ones already on the shop floor. If your requirement falls between two standard beds, ask about a custom bed rather than defaulting upward.
- 2
Set Power From Material and Thickness
Decide the thickest material you must cut and the speed you need on your highest-volume thickness. Those two numbers set the power band. Under-specifying to save capital usually costs more in cycle time across the machine’s life than it saved at purchase.
- 3
Plan the Safety Zone Into the Layout
An open bed does not contain the beam in a housing, so the working area needs a demarcated and guarded safety zone with wavelength-rated eye protection. This is floor space, and it has to be drawn into the layout at the planning stage rather than found afterwards.
- 4
Confirm Crane Access and Material Flow
Overhead loading is the strength of this configuration, so make sure you can actually use it: crane reach over the bed, a staging area for incoming sheet beside the machine, and somewhere for finished parts and skeleton to go. Add the control cabinet, the chiller and the extraction run.
Avoid These Buying Mistakes
6 Mistakes Buyers Make on a Single Pallet Machine
1
Leaving the safety zone out of the floor plan. The demarcated guarded area around an open bed is part of the machine’s footprint in practice. Discovering that at installation means moving something else instead.
2
Sizing the bed for today’s work rather than the next two years. Power can be discussed and options can be added, but the bed is fixed for the life of the machine. Size it for the orders you intend to win.
3
Under-specifying power to protect the budget. A machine that cuts too slowly for your thickness costs you the difference back in cycle time, every shift, for years.
4
Not planning where material and finished parts will sit. Overhead loading only helps if there is a staging area beside the machine. Without one, the crane becomes the bottleneck instead of the laser.
5
Treating fume extraction as an accessory. Extraction sized for your material – and particularly for coated, painted or galvanised stock – is part of the specification, not something to shop around for after commissioning.
6
Comparing quotes on machine price alone. A lower-priced machine without India-based spares, service engineers and a real warranty is not a saving the first time it needs unplanned maintenance.
Where It Is Used
Industries and Applications
The single pallet machine is the general-purpose flat-bed cutter of the range, which is why it turns up across almost every fabrication sector in Indian manufacturing.
- Sheet Metal & General Fabrication
- Job Work & Contract Laser Cutting
- Automotive & Auto-Ancillary
- Electrical Panel & Switchgear
- Structural Steel Fabrication
- Agricultural Equipment Manufacturing
- Pump, Valve & Industrial Engineering
- Elevator, Racking & Storage Systems
- Stainless Steel Furniture & Kitchen Equipment
- Tool Rooms & Maintenance Workshops
Typical output covers the full range of flat-sheet fabrication: brackets, mounting and base plates, machine frames, panel and enclosure blanks, gears, discs, gaskets and profile-cut components in mild and carbon steel, stainless steel and aluminium. Fiber laser is the correct technology for these metals and is not the right cutting technology for plastics, rubber, wood or glass – for plastic sheet, a CO2 laser cutter is the correct machine.
Keeping It Running
Maintenance and Safety in Practice
This is the simplest machine in the cutting range to maintain, but “simplest” is not “nothing” – here is what to actually budget time for.
| Routine Task | Typical Frequency |
|---|---|
| Protective window and lens cleaning, nozzle check and replacement | Daily to weekly, depending on usage |
| Bed slat and dross tray cleaning | Regular – build-up affects how the sheet seats and how cleanly parts drop |
| Rail and guide lubrication | Per machine manual schedule |
| Extraction and filter check | Regular, and sized for the material being cut |
| Safety zone guarding, signage and interlock check | Regular – this is the primary protection on an open type machine |
| Chiller and cooling system check, full technical inspection | Cooling regularly, especially before multi-shift runs; inspection annually |
Safety, in practice: because the beam is not contained by a machine housing, the working area needs a demarcated and guarded safety zone, wavelength-rated eye protection for anyone inside it, and clear operating discipline about who may be near the bed while the machine is running. Fume extraction matters wherever coated, painted or galvanised material is being cut, and should be sized for the worst material you run rather than the average one. The machine’s interlocks and guards exist to stop the beam firing during an unsafe condition and are never to be bypassed for convenience, including during setup. Consumables in normal operation are assist gas, nozzles and protective windows.

Straight Answers
Frequently Asked Questions
The questions manufacturers ask most before ordering a single pallet laser cutting machine.
It is a flat-bed fiber laser cutting machine with one working bed, open on all sides rather than enclosed, where sheet or plate is loaded directly onto the bed and the cutting head travels over it on a CNC-controlled gantry. It is also called an open type single bed or single table machine. Sigma Mechotronics Pvt. Ltd. builds it from 1.5 kW to 20 kW on six standard bed sizes from 3200 x 1600 mm to 6500 x 2500 mm, and in custom bed sizes to a customer’s drawing.
Three practical ones. Stock can be craned or lifted onto the bed from overhead and from any side, so oversized, heavy and awkwardly shaped material is workable without fitting through a fixed opening. The operator has unrestricted access to the whole bed for part picking, skeleton removal and slat cleaning. And it is mechanically the simplest configuration in the cutting range – one bed, no pallet-changer drive, no enclosure interlocks – so there is less to service and less that can stop the machine.
Yes. The laser source, cutting head, motion system and assist-gas system are the same across the flat-bed range, so material range, thickness capability and edge quality are identical at the same power and bed size. Cut quality is set by power, assist gas, nozzle condition and parameter setting, not by body type or by how many beds the machine has.
Choose against your largest regular part rather than your average one, leaving margin for clamping and nesting. As a guide: 3200 x 1600 mm for compact workshops and panel work, 4000 x 2000 mm as the common all-round fabrication size, 6000 x 2000 mm and 6300 x 2000 mm for long-format parts, 6500 x 2000 mm where nesting allowance on 6 metre stock is tight, and 6500 x 2500 mm where your width requirement genuinely exceeds 2000 mm.
Yes. Sigma Mechotronics Pvt. Ltd. manufactures the single pallet machine in customer-specified bed sizes as well as the six standard ones. A custom bed makes sense when your requirement falls between two standard sizes, when the building rather than the work sets the limit, when the machine has to fit an existing layout, or when one dominant sheet format would cut nesting waste on every sheet. Send your part dimensions, material and thickness range, and a shop-floor drawing with clearances, and our engineering team will confirm the right build.
Power follows the thickest material you must cut and the speed you need on your highest-volume thickness. Broadly, 1.5 kW to 3 kW suits thin and medium gauge sheet and lower-volume job work, 4 kW to 8 kW covers the general production middle across sheet and medium plate, and 10 kW to 20 kW is for thick plate and high-speed thick-section cutting at volume. Exact thickness and speed vary with material grade, assist gas and finish, so confirm your specific requirement with our applications team rather than working from a general band alone.
More than the bed dimension. Budget for the machine footprint, the demarcated safety zone around the open working area, operator access on the loading side, a staging area for incoming sheet and outgoing parts, plus the control cabinet, the chiller unit and the extraction ducting run. Crane reach over the bed matters as much as floor area. We confirm exact footprint and clearance against your shop drawing during the pre-order consultation, since it varies by bed size.
Because the beam is not contained by a machine housing, an open type machine needs a demarcated and guarded safety zone around the working area, wavelength-rated eye protection for anyone inside it, clear signage, and operating discipline about who may approach the bed while the machine is running. Fume extraction sized for the material being cut is also required. The machine’s own interlocks and guards must never be bypassed, including during setup and troubleshooting.
Mild and carbon steel, stainless steel and aluminium sheet and plate are the core materials, with titanium, brass and copper also cut – the last two being highly reflective at the fiber wavelength, so a back-reflection protected cutting head should be confirmed if you run them regularly. Fiber laser is not the correct cutting technology for plastics, rubber, wood, leather or glass; for plastic sheet, a CO2 laser cutter is the right machine.
Standard fiber laser maintenance and nothing beyond it: protective window and lens cleaning with nozzle checks, bed slat and dross tray cleaning, rail and guide lubrication per the manual, extraction and filter checks, cooling system checks before multi-shift runs, and an annual technical inspection. With one bed and no pallet-changer mechanism or enclosure interlocks, this configuration has the shortest maintenance list in the cutting range.
Price depends on laser power, bed size, whether the bed is standard or custom, and the options specified with the machine – a 1.5 kW machine on a 3200 x 1600 mm bed and a 20 kW machine on a 6500 x 2500 mm bed sit at very different points in the same range. We quote against a confirmed specification rather than publishing a fixed figure, because an incorrectly specified machine is a poor investment at any price. Send your material, thickness, part sizes and required power for a detailed quotation, and mention if you need multi-machine pricing.
A 2-year warranty covering manufacturing defects in the machine body, laser delivery system, control electronics and motion system, handled directly by Sigma Mechotronics Pvt. Ltd. rather than through an agent or overseas supplier. Installation and commissioning at your premises, parameter setting for your material and operator training are part of the supply, and spares are held in India. Every purchase comes with a GST tax invoice under your GSTIN.
Yes, and where edge quality on a specific grade or thickness decides the purchase, we recommend it. A sample trial on your actual material and thickness is the most reliable way to confirm the machine meets your specification before committing capital. Facility visits to our Ahmedabad plant are welcome by appointment – contact us with your material, thickness and required outcome to arrange one.
