Servo Positioning

Listing ID #3758500

The chamfer had controlled depth for rivet seating. The depth control on the chamfer had to be mainatained within 30 microns for correct. The sustomer was using an hand operated drilling machine with mechanical dead stop. The depth control was very difficult in this setup and was set up time was. This now has been replaced by our machine which has a 1.5HP spindle with 500-2800 RPM stepless speed variation through VFD interface. The depth, feed and rapid return of the tool is by the servo motor coupled to ballscrew. The touch screen HMI can be used to program the spindle speed, drill feed, rapid return and dwell. This machine can be used for even tapping with a compensatory tapping chuck. Different fixtures have to be made to align the hole position to the spindle position. After fixture setup, the machine can be used in continuous auto-cycle for mass production.
