CASE STUDY Increased Feed Rates

KYOCERA SGS Precision Tools Increased Material Removal

SAVES AN END USER $263,100 ANNUALLY BY INCREASING Increased Tool Life

METAL REMOVAL RATE & OPTIMIZING CYCLE TIME

BACKGROUND RESULTS

The hook plate is a primary support piece of a fork lift The changes made to the application combined with the high performance geometry of the assembly and requires precise machining tolerances. The KSPT Series 33 End Mill resulted in an annual gain of 104.25 production hours. In addition to

INDUSTRYapplication calls for machining .230” from the peripheralmeeting the goal for improved cycle times, tool life was increased from 20 to 240 parts per
Lift Equipmentof the part at an axial depth of 1-1/2”: the A514 materialtool. This reduced the tooling cost per part by 91%, allowing the end user to achieve a total

used in this application is similar to 4140. The competitor annual cost savings of $263,100. COMPONENT tool was performing this in four rough passes followed by Hook Plate a single finish pass.
