LKM 840

α/β-SiAION for milling

Outstanding toughness combined with highest wear resistance make the LKM 840 ceramic a high performance grade for rough milling of CI, NCJ and HRSA materials. High wear resistance allows high cutting speeds. This results in large removal rates and at the same time excellent process reliability. Using LKM 840 the reachable tool life of cast iron materials can be improved distinctly. When milling HRSA materials, a cutting speed of up to 1000 m/min is possible. Increase of productivity, decrease of production time and cost. LKM 840 is the ideal grade to enhance the added value when milling.
