Product Details

Machine main structure, configuration:

1. GGW28300 seven axis control CNC vertical grinder, control system using Siemens 840D. A fixture to grinding inner hole, excircle, end, various raceway surface.

2. machine adopts double column double grinding high precision NC rotary turret. The left grinding rack turret, turret on a vertical a horizontal wheelhead layout, grinding head can be automatically rotating any angle, high precision circular grating rotary angle and built-in control. The right grinding rack arranged a vertical wheelhead. So the grinding head can be grinding at the same time to improve the efficiency of.

3. reciprocating grinding rack adopts balance hydraulic balance device, improve the stability and the implementation of components of life. Mill frame assurance, power-off situation can prevent the knife and cut off the self-locking, after grinding mill frame under the action of gravity decline.

4.ensure the rigidity of the machine tool, machine tool used in Germany imported FAG/INA high vibration resistance of the roller linear guide, and equipped with damping device, effectively absorb vibration, eliminate grinding chatter.

5. machine tool feed, the reciprocating screw are used in Japan NSK imports of large diameter high precision ball screw.

6. CNC turret imported from Germany, with a non locking structure to enhance the continuous rotary hydraulic. Rotary Siemens servo motor +OTT worm gearing, positioning is controlled by the HEIDENHAIN of high precision circular gratings. The turret ± 180 automatic rotating, automatic clamping, automatic positioning.

Spain's MYL, electric grinding head. The vertical grinding with high precision, high power, high rigidity, and with MARPOSS built-in automatic dynamic balancing and anti air unit. Horizontal wheelhead uses high precision mechanical grinding head, multi wedge belt drive.

7. workpiece spindle adopts high precision spindle, spindle, double support, ensure high radial load capacity and rotation accuracy, axial, each support, lower supporting console surface floating quantity, upper support part weight and chuck weight. Imported precision reduction drive unloading belt pulley, the belt pulley drives the workpiece spindle. The Finland VACON inverter VVVF speed. The hydrostatic spindle rotation accuracy, maintenance, convenient and reliable adjustment.

8. X machine, Z axis, U axis, W axis optional Heidehan grating closed-loop control.

9. machine according to the requirements can be equipped with single point diamond dresser, single point arc dresser or shaped diamond idler wheel dresser, which arc truing and dressing is driven by servo motor.

10. machine optional power permanent magnetic chuck or disk. With the suction cup, used with T groove is used for mounting a workpiece support. According to the workpiece size, electromagnetic sucking disc magnetic force adjustable, and the anti magnetic device and the loss of functional magnetic protection, with magnetic, magnetic display device.

11. machine can adopt totally closed shell, equipped with automatic opening and closing device.

12. machine water tank, oil tank, electric box and imported electric grinding head can change the selection of air conditioning temperature control.

13.Modular design with machine, can meet the special requirements of users in the technology and specifications.

Machine tool main purpose and scope:

Mainly used for disc tooth and large fan bearings, bearing parts in the hole, the end surface and the raceway grinding. Ensure the inner hole and the end face or rolling precision and surface.
