CNC Plasma Cutting to 60 mm – Steel, Stainless Steel and Wear-Resistant Steel
Economical plasma cutting for steel, stainless steel and wear-resistant steel from 8 to 60 mm – on large format with automatic bevel cutting, no minimum quantities and direct further processing in Lorch, Germany.
8 – 60 mm Thickness
Economical for plate thicknesses from 8 to 60 mm – faster than oxy-fuel, more precise for stainless and special steels.
20,000 × 3,500 mm Format
Large-format blanks cut in one pass – no split cuts, no repositioning.
Bevel ±45°
Automatic bevel at the cutting head – weld seam preparation without secondary operations.
Steel · Stainless · Wear-resistant
Structural steel, stainless steel, wear-resistant steel and fine-grain steel to S1100 – all key materials from one machine.
Direct Further Processing
Welding, CNC machining, shot blasting and coating without external interfaces in Lorch.
Contract Work Without Minimums
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 wear-resistant grades.
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.
When plasma cutting stainless steel, heat tint is minimised by adapted gas flow and cutting parameters. 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.

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-grained structural steel up to S1100 – high-strength
- Hardox 400 / 500 – up to 60 mm
- Stainless steel 1.4301, 1.4571 – corrosion-resistant
- XAR 400 and other wear-resistant steels
For structural, fine-grain and wear-resistant steel 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°
- Wear parts for earth-moving and processing equipment
Plasma-cut parts can be welded, machined, blasted and painted in the same facility. Quality documentation to DIN EN ISO 9001:2015 with full material traceability is available.

Frequently asked questions about CNC plasma cutting
Is stainless steel plasma cut, and how is heat tint at the cut edge limited?
Yes, stainless steel is cut by CNC plasma cutting up to 60 mm. Process parameters and shielding-gas flow minimise heat tint and oxidation at the cut edge.
How does CNC plasma cutting work?
In CNC plasma cutting, an electric arc is directed through an ionised gas that separates the workpiece. At Bock, a Messer OmniMat machine with an HPR-400 plasma unit cuts to drawing on a format of 20,000 × 3,500 mm.
Up to what plate thickness are steel and wear-resistant steel plasma cut?
Up to 60 mm – structural steel, fine-grain structural steel up to S1100, stainless steel and wear-resistant steels such as XAR 400. Structural, fine-grain and wear-resistant steel over 60 mm wall thickness is oxy-fuel cut, up to 200 mm.
Is underwater plasma cutting also carried out?
Yes. In addition to the Messer OmniMat machine, a Zinser 4125 underwater plasma cutting machine is available: format 8,000 × 2,500 mm, cutting thickness up to 30 mm, bevel cutting up to ±40°.
What determines the cut quality in plasma cutting?
The drawing and tolerance specification: the CNC plasma cuts are produced accordingly, so that the parts can be processed further without extensive rework. The Messer OmniMat machine automatically cuts weld bevels up to ±45° in the same operation.
