CNC Gantry Vertical Axis Disc Double End Grinding Machine MKY7840

CNC Gantry Vertical Axis Disc Double End Grinding Machine

MKY7840

1. This machine tool is mainly used for large surface grinding of precision parts such as compressor vanes, hydraulic pump blades, gauge blocks, etc. It can also be used for grinding the two end faces of small high-precision piston rings, bearing rings, valve seats, alloy blades, watch accessories, mobile phone accessories and other parts.

2. The machine tool adopts a vertical gantry structure, and the upper and lower grinding heads are vertically placed on the same center line, with good rigidity.

3. The machine tool spindle adopts a precision electric spindle dedicated to double-end grinders. The bearings use P4 precision bearings produced by NSK, equipped with a special constant temperature water tank to control the temperature, reduce the influence of spindle temperature changes on the final size of the grinding workpiece, and the spindle speed adopts AC inverter stepless speed regulation to meet various grinding process requirements.

4. The machine tool adopts a disc feeding method, and the feeding speed can be variable frequency stepless speed regulation. The feeding mechanism and the column adopt a hinged structure, which is flexible to open. It is convenient to replace the grinding wheel.

5. The machine tool grinding head advance and retreat guide rail adopts high-precision cross roller guide rail, which has good rigidity, high repeat positioning accuracy and long service life.

6. The advance and retreat of the upper and lower grinding heads of the machine tool are controlled by the servo system to achieve a feed accuracy of 0.001mm.

7. Equipped with a constant temperature cooling system with a magnetic separator and a paper belt filter.

8. Machine tool working accuracy:

Dimension difference <0.01mm;

Parallel difference <0.005mm;

Surface roughness Ras0.25μm.
