high speed machining
Using a Johnford SHV-1000 with a Weiss 24,000 RPM HSK-63 spindle and with linear ways and a Fanuc 18i control, we are able to provide a fine finish to .00001 cusp height. This provides us the ability to rough up to 600 ipm and finishing speeds up to 150 ipm to achieve these results. We use OSG tools with a WXL or WXS coating which provides a longer lasting tools with more accurate results. We typically cut to a -.0008 stock. Between the surface finish capability and
negative stock condition, polishing and fitting are significantly
reduced.
