Machining of Nickel-based Alloys

Ceramic cutting materials and whisker ceramics are our successful duo in the machining of nickel-based alloys. The focus is on turning and grooving for roughing and semi-finishing applications. With our ceramic grades LST 320, LST 370 and our whisker ceramic grade RST 330, you can machine your nickel-based alloy components easily and quickly with our top grades. Why not take a look at the performance of our SiALON cutting materials right now?

LST 320

Ceramics for turning, grooving, roughing, semi-finishing, profiling, broaching

Cutting values:

  • Vc (m/min) = 200 - 350
  • f(mm) = 0.10 - 0.25
  • ap (mm) = 2.0 - 3.0


LST 370

Tool System for High-Performance Machining

Our ICT tool system shows its strengths when process reliability is an important criterion for you when turning HRSA materials. We offer it with and without high-pressure cooling. As a high-pressure tool, the cooling lubricant reaches the effective zone directly and at the same time ensures reliable chip breaking.
