YS7232/YS7232G High Precision CNC Worm Wheel Grinding Machine

The machine tool is mainly applied to the precision grinding of gears in the industries of new energy vehicles, aerospace, passenger cars, commercial vehicles, precision reducers, etc. The batch machining accuracy can reach the level 4-5 of GB/T10095.1-2008 standard.

The main performance and characteristics of the machine tool:
◆ The machine is an eleven-axis five-linkage CNC gear grinding machine. YS7232G series gear grinding machine is a full CNC high-precision and high-performance gear grinding machine developed by Chongqing Machine Tool and British PTG (HOLROYD) Company in strict accordance with the development process of European high-end precision machine tools.
◆ The machine tool adopts European original imported high precision screws with pre-loaded screws for each linear axis.
◆ The grinding wheel spindle adopts the high-power integral type electric spindle imported from Germany, the spindle bearing adopts the ceramic ball bearings imported from Europe, and each linear axis adopts the high rigidity rolling linear guideway imported from Europe.
◆ The machine adopts Siemens 840Dsl system, through the system’s multi-channel control platform, flexible control of eleven numerical control axes, to realize automatic workpiece clamping, automatic grinding wheel dressing, high-speed tooth pairing, automatic grinding demonstration, automatic dressing demonstration, automatic margin allocation and automatic grinding of the entire machining process of fully automatic control.
◆ The software of the machine tool has perfect functions and is in the leading position in China, which can realize various complicated dressing functions such as arbitrary tooth direction, tooth surface distortion compensation, point dressing (arbitrary tooth shape dressing), tooth surface mesh grinding, double-pressure-angle asymmetric gear grinding, and small-bevel gear grinding.
