Product Description

1.Product Introduction
* The lathe is controlled by CNC system, the CNC function of complete machine is realized by all-digital alternation current servo driver's controlling over two servo motos. The horizontal traverse X axis and longitudinal traverse Z axis of platen are driven by servo motors. They have non-intermittent motion through direct-connection ball screw of fine coupling, to make the whole grinding process realize automatic processing according to program. In this way, one person can manage multiple machines: Labor cost can be reduced for users, and productivity can be enhanced.

* Grinding ball materials: A105, 2Cr13, 304, 304L, 316, 316L, LF2, F51, 17-4PH, Monel, ENP, Chrome Plating, Tungsten Carbide, Stellite, Inconel, and ceramic ball valves etc.
