Product Details

Introduction:

  1. M K280 CNC internal grinder is a two-axis CNC internal grinder, which is mainly used to grind the inner hole, step hole, inner cone hole, inner end surface and outer end surface of the workpiece. The grinding cycle is automatically completed, including automatic feed , Automatic tool retraction; Coarse grinding, fine grinding; Automatic dressing wheel, automatic compensation, interpolation correction and other functions.

  2. High Precision Cnc Internal Grinding MachineM K280 is fixed by the workpiece box, the table (z axis) reciprocates longitudinally, and the wheel slide (X axis) feeds horizontally. Both X and Z axis movements are driven by a ball screw driven by a servo motor.

  3. The high-precision double-cylindrical roller bearing is adopted for the bearing of the workpiece spindle box. The motor is driven by AC frequency conversion, and the workpiece speed is adjusted steplessly. The workpiece box is installed on the rotating plate of the bridge plate. It can move laterally and rotate the angle to meet the grinding requirements of large aperture workpieces and tapered workpieces.

  4. High Precision Cnc Internal Grinding MachineM K280   

  5. control system uses the German Siemens 828 numerical control system. The spindle of the grinding wheel adopts a high-precision mechanical spindle, the motor is AC frequency-converted, and the speed of the grinding wheel is adjusted steplessly.

  6.  M K280 CNC internal grinder adopts closed cover, front rotary operation table and rear backpack type electric box.
