Machining of Heat Resistant Super Alloys
Ceramic cutting materials and whisker-reinforced ceramics are our high-performance combination for machining HRSA materials. The focus is on turning and milling applications for roughing and semi-finishing operations. With our ceramic grades for turning - LST 320 and LST 350 - our whisker-reinforced ceramic grade RST 330, and our LSM 800 grade for milling, you can machine components made from nickel-based and cobalt-based alloys quickly, reliably and efficiently.
Discover our new Ceramic Fit Check
We evaluate your specific application from a technical perspective: material, machining operation, cutting conditions, and objectives. You will receive a well-founded initial assessment of whether ceramic cutting materials make sense for your process.

HPC - High Pressure Coolant Tooling System
The special feature of our HPC tooling system is that the coolant is supplied through the clamping finger. The coolant outlets on the finger are designed to deliver coolant directly to the active zone where it is needed. A coolant pressure of up to 200 bar can be applied to the tool.
Another advantage of high-pressure cooling is that the chip can be broken into small pieces. This eliminates process-disturbing ribbon chip.
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.
Special Tools
The machining task you are facing cannot be solved with standard tools? No problem. Our engineering team will develop the tool that solves the task for you. No matter whether the machining task requires a special insert geometry or a special tool shape.
The tool is then manufactured as quickly as possible in our own production facility in Germany.
Milling of HRSA Materials with Ceramic End Mills
Machining heat-resistant superalloys places high demands on tools, as heat, chip breaking and wear cause extreme stress on the tool cutting edge and place high demands on the cutting material. Our new white paper shows practical strategies for overcoming the challenges of milling Inconel & Co with ceramic end mills.
