Equipment Highlights

Equipment Highlights

(1) the German Siemens (SIEMENS)840D CNC system.

(2) Using static and dynamic pressure bearing dynamic balance high-speed electric spindle, equipped with CBN grinding wheel, to achieve 80-120 m/s high-speed grinding of the camshaft.

(3) High-precision and high-rigidity direct-drive closed rectangular hydrostatic guide rail is adopted to eliminate the phenomenon of low-speed crawling.

(4) The workpiece rotation axis adopts the acceleration and deceleration control method (software copyright: 2010SR004346) to improve the grinding accuracy.

(5) The grinding wheel spindle adopts built-in online dynamic balance.

(6) The diamond roller is used to dress the CBN grinding wheel online, which improves the machining accuracy and machining efficiency of the machine tool.
