CASE STUDY
KYOCERA SGS Precision Tools
SAVES AN END USER $263,100 ANNUALLY BY INCREASING
METAL REMOVAL RATE & OPTIMIZING CYCLE TIME

BACKGROUND
The hook plate is a primary support piece of a fork lift
assembly and requires precise machining tolerances. The
INDUSTRY application calls for machining .230” from the peripheral
Lift Equipment of the part at an axial depth of 1-1/2”: the A514 material
used in this application is similar to 4140. The competitor
COMPONENT tool was performing this in four rough passes followed by
Hook Plate a single finish pass. KYOCERA SGS Precision Tools (KSPT)
proposed a single roughing and finishing pass utilizing a
MATERIAL
1” Series 33 End Mill.
ASTM A514 HTSTL PLT 100 KSI
PRODUCT GOALS
KSPT Series 33 End Mill The primary goals of this test were to reduce cycle time,
AlTiN Coated increase tool life, and decrease overall tooling cost.
APPLICATION STRATEGY
Peripheral Machining Working with the end user to understand their needs, KSPT
CNC INFO approached the application with a 1” three flute Series 33
Haas VF7 End Mill, allowing for increased tool life and greater feed
rates to improve cycle times.
