HIRSCHMANN's micro technology rotary spindle for wire EDM combines the newly designed H80R.-MAC high-speed rotary spindle with the H1680.AC4 variable speed AC control, making the production of miniature round parts with small diameters and finer finishes possible. The H80R.MAC incorporates special bearings, minimum radial run-out, and variable high-speed control.
Unlike grinding, there are no side forces from wheel contact. Smaller diameters without deflection are possible. In addition, contour shapes are programmed into the EDM control, eliminating contoured wheels and reducing setup times.
Some of the product uses are: core and ejector pins for micro molds, medical applications, miniature valve slides, electrodes for sink EDM, and micro pump parts.
Developed in conjunction with the Institute for Mikrotechnik Mainz GmbH, Germany, this new spindle along with refined generator settings of the wire E D M , a l l o w s t h e EDM turning of diameters down to 0.05mm (0.002-in.) with surfaces to Ra 0,2.
