turning and milling stainless steel

Stainless steel combines corrosion resistance, strength and suitability for hygiene – properties that make it indispensable for many industries, but make its machining challenging.

Stainless steel refers to steels with a high degree of purity; the well-known corrosion- and acid-resistant grades V2A (e.g. 1.4301) and V4A (e.g. 1.4571, 1.4435) contain chromium and nickel, which form a protective passive layer. However, it is precisely these alloy constituents that make machining more difficult.

Challenges in processing

Stainless steel is prone to work hardeningIf the cutting edge is not kept cleanly in engagement, the surface work-hardens and wear increases. The low thermal conductivity also leads to Heat buildup on the cutting edge. Both require coordinated cutting data, sharp tools and effective cooling.

• Constant high feed rate to avoid work hardening
• High-quality, wear-resistant cutting materials and coatings
• Adequate and targeted cooling lubrication to prevent heat accumulation
• Stable clamping situation for dimensionally accurate, low-burr results

Experience decides

From corrosion- and acid-resistant steels to duplex and super duplex materials and implant steels: the range of stainless steels is vast, and each grade has its own behaviour. Many years of experience in turning and milling is the prerequisite for precision parts that impress over the long term.
