Metalworking fluids filtered economically
Cost effective filtration system designed to handle both high flow levels and fine particle removal has been developed for a wide range of metalworking applications.
Workholding systems have high accuracy
Hirschmann Engineering is supplying the workholding system for seven of the 600 Centre machine tools being demonstrated at the Productivity Partnership exhibition.
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 set-up 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, Germany, this new spindle along with refined generator settings of the wire EDM, allows the EDM turning of diameters down to 0.05mm (0.002in) with surfaces to 0.2 micron Ra.
The H80R.MAC Rotating Spindle and H1680.AC4 Speed Control Unit are available for delivery.
Complete illustrations of all rotary tables and axes are available in the NEW free catalog RE 4905, Stainless Steel Rotary Indexing Tables and A-Axes for wire and die sinking EDM.
