Compact insert cartridge design doubles speeds

By incorporating a small, very compact insert cartridge into its latest Feed-Jet, multiple tooth milling cutter system, LMT’s Kieninger division has developed a cutter that is able to run at up to double the speed of a normal face mill due to the number of inserts it can carry maintaining the same rate of feed per tooth. In addition, the new cutter requires lower torque from the machine spindle drive, has a high precision body, and the PCD-cartridge design enables special requirements to be defined such as high cutting depth, surface roughness and percentage contact area. The cutter body design also has a minimum number of separate components and uses high precision stress-free friction clamping giving a simple fine adjustment of each cutting edge for perfect ‘flat’ running and minimal creation of rags or burrs. The Feed-Jet cutter bodies are all steel and range in diameter from 63 mm with eight teeth to 125 mm with 16 teeth.
