ELEMENT TECHNOLOGIES Hydrostatic structure High-precision aspherical & non-axisymmetric surface generator uses fully hydrostatic configuration of a type never before seen in the world. The spindle, slide and feed screw drive systems are all configured in a structure without any metal contact at all. The machine ensures smooth maneuverability and fine positioning accuracy unparalleled in the world. On-machine measuring system In addition to the absolute mechanical accuracy, on-machine high- precision measurement is essential to high precision machining on Using unique technologies, we have...

Hydrostatic bearings are used for the B-axis table. Direct drive motor achieves high rotational precision and stability with noncontact drive system. Machining precision is not affected by discrepancies in tool shape because processing with tools and grinding wheels are done as single-tool point. Tool and work piece interference is uncommon when machining small dies. ASP Element technologies B-axis table Not using B-axis Using B-axis 12
