CNC Plasma Cutting to 60 mm – Steel, Stainless Steel and Hardox
Economical plasma cutting for steel, stainless steel and Hardox from 8 to 60 mm – on large format with automatic bevel cutting, no minimum quantities and direct further processing in Lorch, Germany.
Economical for plate thicknesses from 8 to 60 mm – faster than oxy-fuel, more precise for stainless and special steels.
Large-format blanks cut in one pass – no split cuts, no repositioning.
Automatic bevel at the cutting head – weld seam preparation without secondary operations.
Structural steel, stainless steel, Hardox 400/500 and fine-grain steel to S1100 – all key materials from one machine.
Welding, CNC machining, shot blasting and coating without external interfaces in Lorch.
Individual parts, prototypes and series parts manufactured equally to drawing.
CNC Plasma Cutting – Process and Capacity
In CNC plasma cutting, an electric arc is directed through an ionised gas that separates the workpiece. The process is particularly economical for plate thicknesses up to 60 mm and is suitable for structural steel, stainless steel and Hardox 400/500.
The Messer Omnimat machine with HPR-400 plasma unit travels over a format of 20,000 × 3,500 mm. Automatic bevel cutting to ±45° enables weld seam preparation in a single operation – no secondary operations required.
CNC plasma-cut parts are manufactured to drawing. Contract manufacturing in Lorch covers individual parts and small series without minimum order quantities.
CNC plasma cutting quality at Bock is managed under DIN EN ISO 9001:2015. Material traceability from sheet certificate to finished part is maintained and documented. Plasma-cut parts can be welded, drilled, surface-treated and painted entirely within the Lorch facility. This single-source capability is especially relevant for series components and complex fabrications requiring multiple manufacturing steps – from cutting and welding through boring mill machining, shot blasting and final industrial painting. Bock's documented quality management under DIN EN ISO 9001:2015 ensures consistent accuracy and full material traceability from raw sheet certificate through to the finished plasma-cut component.
Plasma-cut parts in stainless steel are produced without heat tint when the shielding-gas flow is set accordingly. Our contract manufacturing also covers series cutting for recurring components in small and large batches.
After cutting, components can be processed further directly in welded-assembly production, CNC machining and surface treatment – all in the same facility in Lorch. Quality assurance is carried out in accordance with DIN EN ISO 9001:2015 with documented traceability.
Machine data
| Machine | Format | Cutting thickness | Bevel cut |
|---|---|---|---|
| Messer Omnimat HT-L 5000 · HPR 400 · Plasma cutting system | 20,000 × 3,500 mm | up to 60 mm | ±45° |
| Zinser 4125 · Underwater plasma cutting system | 8,000 × 2,500 mm | up to 30 mm | ±40° |
Materials for CNC Plasma Cutting
CNC plasma cutting is suitable for steels and special steels:
- Structural steel S235, S355 – 3 mm to 60 mm
- Fine-grain structural steel to S1100 – high-strength
- Hardox 400 / 500 – wear-resistant steel up to 60 mm
- Stainless steel 1.4301, 1.4571 – corrosion-resistant
- XAR 400 and other wear-resistant steels
For thicknesses above 60 mm, oxy-fuel cutting is the more suitable process.
Typical Applications
CNC plasma cutting at Bock is used for:
- Precision blanks for welded assemblies and steel fabrications
- Web plates, ribs and brackets for vehicle and crane systems
- Stainless steel parts for plant and vessel engineering
- Bevel cuts as weld seam preparation to ±45°
- Hardox wear parts for earth-moving and processing equipment
Plasma-cut parts can be welded, machined, blasted and painted in the same facility.
