      MK8432A CNC roller ring grinder is mainly used for grinding tungsten carbide carbide ring for high-speed wire production. Rough grinding, semi-precision grinding, fine grinding and non-sparking grinding of the outer circle of the hard alloy roller ring and the R-groove with a shaped diamond grinding wheel are necessary finishing equipment in the machine repair workshop of the rolling mill.

      1. The machine tool adopts the German Siemens SINUMARIK 828D numerical control system, which controls the grinding wheel feed and the table movement respectively, and automatically completes the grinding of the outer circle of the roller surface and the various grooves.

      2. The workpiece headstock spindle is driven by variable frequency speed regulation, and the corresponding speed can be set according to different workpiece parameters.can be set according to different workpiece parameters.

      Tension mandrel is installed on the headstock main shaft. Put the roller ring on the tensioning mandrel, and use an Allen wrench to tighten the locking screw at the end of the tensioning mandrel to complete the self-centering installation and fastening of the roller ring to be processed on the machine tool.

      3. The spindle of the grinding wheel adopts high-precision rolling bearings, and uses an independent box to seal the forced lubrication and cooling. It has excellent performances such as high rotation precision of the spindle, high rigidity, and long service life of the bearing.

      The grinding wheel spindle is driven by a high-power (18.5kw) motor.

      4. The working table and the grinding rail support rail are supported by high-precision and heavy-duty linear rolling guide rails. The precision-preloaded rolling guide rail pair has a small coefficient of dynamic and static friction, high sensitivity, and stable and reliable operation.

      Both the grinding wheel frame and the worktable are driven by servo motors, which are directly driven by the high-precision gapless ball screw, so the transmission accuracy is high, and there is no gap in the reverse direction. Their movement can be automatically completed by program control, or can be manually adjusted by the electronic hand wheel. to fulfill.

      5. The working table is divided into two working tables, the upper working table can rotate in the horizontal plane, and the upper and lower working tables are usually connected by pressing plates.

      The upper working table adopts the inclined plane to support the head frame, which is convenient for drainage, and the weight of the head frame and the workpiece is pressed on the guide rail at the same time, which can automatically realize that the head frame main axis is parallel to the inclined side of the table.

      6. The machine tool uses an automatic lubrication system to automatically lubricate the guide rails and screw rods to ensure that the machine tool has always been in good condition, stabilize the machine tool accuracy, and extend the life of the machine tool.

      7. The machine tool's coolant is cleaned with a paper belt filter, which has a good filtering effect, which not only ensures the cleanliness of the coolant, but also greatly increases the service life of the coolant.
