ZCS-QMK1412 series”Using an air static pressure workpiece electric spindle, an air static pressure inner circular grinding wheel electric spindle, an air static pressure outer circular grinding wheel electric spindle, an air static pressure tailstock top shaft, X/Z high-precision air floating guide rails, and a high-precision numerical control system from Mitsubishi, Japan, six axis air floating control is achieved. Achieve a machining accuracy of 0.2um roundness and 1um cylindricity for the entire machine. The specific technical parameters are as follows:

1、 Technical features:

This machine tool has obtained a national invention patent, with the patent name: an inner or outer circular ultra precision grinding machine for pneumatic metal parts. Patent certificate number: ZL 2011 1 0213261.8。

This machine tool is suitable for grinding cylindrical outer circles, inner holes, and end faces, as well as multi-stage cylindrical outer circles, inner holes, and end faces.

This grinder adopts an air static pressure workpiece electric spindle, an air static pressure inner circular grinding wheel electric spindle, an air static pressure outer circular grinding wheel electric spindle, an air static pressure tailstock top shaft, X/Z high-precision air floating guide rails, and a high-precision numerical control system from Mitsubishi in Japan, achieving six axis air floating control. Achieve a machining accuracy of 0.2um roundness and 1um cylindricity for the entire machine.

The fourth axis function is to add a set of linear guide rails and servo motors for installing an inner circular grinding head on one side of the outer circular grinding wheel, achieving the function of completing inner and outer circular machining with one card installation.

The workpiece adopts various installation methods such as high-precision three jaw workpiece chuck (or dedicated pneumatic chuck), high-precision pneumatic static pressure top tip, etc. The front and rear air static pressure top tips have fast and convenient card installation, high precision (rotation accuracy)0.1um）The top hole of the workpiece does not require grinding and precision machining, among other advantages. Additionally, customize specialized fixtures.

The feed of the grinding wheel rack and the movement of the worktable are both driven by AC servo motors through high-precision ball screws.

The inner circular grinding wheel adopts a straight rod type grinding wheel rod installation method.

The workpiece spindle and grinding wheel spindle use Delta series variable frequency controllers to achieve stepless speed regulation.

The grinder is equipped with pressure sensors at the inlet of the air and water circuits, which have fault alarm protection functions such as overcurrent, overload, air pressure below the lower limit, and cooling water cut-off. And it has communication function with the upper computer (RS-485).
