If you are using a VFD on your spindle (or coolant pump), having one a filter on the power input solved my noise problems. http://www.eastek-intl.com/images/PreoSeriesEB.pdf http://www.wallacecompany.com/cnc_lathe/HNC/00024-1a.jpg If not, using a filter or ferite beads for other power lines might help. ---------- Kirk http://www.wallacecompany.com/machine_shop/ ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
