Wheel Cover Mold Demo Summary
This demonstration is to show the ability of Millstar®
and Makino® to machine hardened materials. Makino's High
Performance Machining Centers and Millstar's High Performance
Cutting Tools utilize high cutting speeds and feeds to create
shorter cycle times while producing a highly detailed work
piece. Segments of mold shown at left.
Machining
Process Summary
The tool paths for this mold were generated using UniGraphics
V15 CAM software. The material machined was H13 (1.2344) hardened
to 50 HRc. The test cut was machined on Makino's A77 Horizontal
Machining Center utilizing Makino's 18,000 rpm 50 taper spindle,
high speed Data Server and Super Geometric Intelligence technology.
Process
Benefits
With Millstar's and Makino's High Performance Machining it
is possible to produce a complex 3-D product that is highly
accurate and with a superior surface finish.
