Different Types of Laser Cutting Machines

Laser cutting machines have become essential in metal fabrication for their ability to deliver fast, precise, and versatile cutting across various applications. Depending on the type of laser source, material, and cutting application, we provide several types of laser cutting machines. STM’s Laser Cutting Machine Types:

1. Open Type Single Pallet Laser Cutting Machine (G Series)

G Series: Basic and Accessible. This is typically an entry-level or standard model. It features an open working area (no full enclosure), making material loading/unloading and observation easy. The single pallet means theres only one working table, so the machine stops cutting while material is being set up or removed. Used for general-purpose sheet metal fabrication.

Work Table Size: 3000 – 6500 × 1500 - 2500 mm (Standard)

Laser Power Range: 1.5 kW & 3 kW

Common Cutting Capability:

• Mild Steel: up to 16 mm

• Stainless Steel: up to 8 mm

• Aluminium: up to 6 mm

Applications: Small to medium sheet cutting, signage, and fabrication jobs

Industry Segments: Job shops, electrical panels, furniture fabrication

2. Large Bed Single Pallet Laser Cutting Machine (GS Series)

GS Series: Bigger Work Area. Similar to the Open Type, but designed with a significantly larger cutting bed to accommodate oversized metal sheets. Still uses a single pallet system. Ideal for users needing to cut large parts or who want to maximize material utilization from large sheets without interruption for cutting.

Work Table Size: 3000 – 8000 × 1500 – 2500mm 

Laser Power Range: 6 kW – 30 kW

Common Cutting Capability:

• Mild Steel: up to 25 mm

• Stainless Steel: up to 12 mm

• Aluminium: up to 10 mm

Applications: Large sheet processing, automotive components, enclosures

Industry Segments: Automotive, industrial fabrication, machine manufacturing

3. Ultra Large Single Pallet Laser Cutting Machine (R Series)

R Series: Maximum Size. Represents the largest format machine in this category. Built to handle extremely large or extra-long sheets of material, often used in industries like shipbuilding, railway carriage manufacturing, or large architectural projects. It still maintains a single pallet setup.

Work Table Size: 8000 – 24000 × 3000 – 4000 mm

Laser Power Range: 6 kW – 36 kW

Common Cutting Capability:

• Mild Steel: up to 50 mm

• Stainless Steel: up to 30 mm

• Aluminium: up to 25 mm

Applications: Heavy sheet metal fabrication, base frames, large covers

Industry Segments: Shipbuilding, construction equipment, heavy fabrication

4. Open Type with Double Pallet Laser Cutting Machine (P Series)

P Series: Features an open frame but includes two exchange tables (pallets). While the laser cuts on one pallet inside the machine, the operator safely unloads parts and loads a new sheet onto the second pallet outside. This dramatically reduces non-cutting downtime and increases overall productivity.

Work Table Size: 3000 – 6500 × 1500 - 2500 mm 

Laser Power Range: 3 kW – 30 kW

Common Cutting Capability:

• Mild Steel: up to 25 mm

• Stainless Steel: up to 12 mm

• Aluminium: up to 10 mm

Applications: Continuous cutting of medium to large sheets

Industry Segments: Job shops, industrial fabrication, machinery manufacturing

5. Enclosed Type Double Pallet Laser Cutting Machine (H Series)

H Series: Safety and Environment. Features a full safety enclosure that covers the entire cutting area. This design minimizes laser radiation exposure, reduces noise, and contains dust/fumes, making it safer and cleaner for the working environment. Often includes an automatic shuttle table (though not explicitly stated, its common) for continuous operation.

Work Table Size: 3000 – 6500 × 1500 - 2500 mm 

Laser Power Range: 3 kW – 30 kW

Common Cutting Capability:

• Mild Steel: up to 25 mm

• Stainless Steel: up to 12 mm

• Aluminium: up to 10 mm

Applications: High-precision sheet cutting, cabinet fabrication, OEM parts

Industry Segments: Electronics, consumer goods, precision manufacturing

6. Sheet & Tube Laser Cutting Machine (M Series)

M Series: Versatility. A combination machine capable of cutting both flat metal sheets and tubes/pipes (square, round, rectangular, etc.). It typically has a flat working table and an integrated rotating chuck system (or separate section) for tube processing. This offers maximum flexibility for job shops that handle a wide range of tasks.

Work Table Size:

• Sheet: 3000 – 6500 × 1500 – 2500 mm

• Tube Diameter: Round Tube:<=220mm, Square tube: <=150mm

Laser Power Range: 1.5 kW – 6 kW

Common Cutting Capability:

• Sheet: up to 16 mm

• Tube: Thickness up to 16 mm and Diameter up to Ø 220 mm

Applications: Frame fabrication, sheet and tube structures

Industry Segments: Furniture, construction, fabrication workshops

7. Enclosed Type Sheet & Tube Laser Cutting Machine (HM Series)

HM Series: Combines the versatility of the hybrid machine with the safety and cleanliness of a full enclosure. This protects operators from the laser and contains dust/fumes generated from both sheet and tube cutting operations.

Work Table Size:

• Sheet: 3000 – 8000 × 1500 – 2500 mm

• Tube Diameter: Round Tube:<=220mm, Square tube: <=150mm

Laser Power Range: 1.5 kW – 6 kW

Common Cutting Capability:

• Sheet: up to 16 mm (MS)

• Tube: Thickness up to 16 mm and Diameter up to Ø 220 mm

Applications: Frame fabrication, sheet and tube structures

Industry Segments: Furniture, construction, fabrication workshops

8. Tube Laser Cutting Machine (T Series)

T Series: Specialized for Profiles. A machine dedicated exclusively to cutting tubes and pipes. It features a robust chuck or clamping system to hold and rotate the tubular material while the laser head moves along its length to create intricate cuts, holes, and shapes.

Work Table Size:

• Tube Diameter: Round Tube:<=220mm, Square tube: <=150mm

Laser Power Range: 1.5 kW – 12 kW

Common Cutting Capability:

• Sheet: up to 16 mm

• Tube: up to Ø 220 mm

Applications: Pipes, tubular structures, mechanical assemblies

Industry Segments: Automotive, furniture, industrial fabrication
