Horizontal Spindle Through-type Double Disc Grinding Machine M7660B

The double disc grinding machine is mainly composed of front bed and rear bed; left and right grinding head; left and right carriage; left and right feed compensation mechanism; Independent grinding wheel dressing mechanism; automatic lifting-lowering mechanism of protective cover; electrical control system; feeding and discharging mechanism and other main components. The left and right grinding wheels, through grinding head driven by hydraulic press, make fast forward and backward movement and achieve a combination of automatic jog compensation and manual adjustment by hand wheel. The double disc grinding machine is designed and manufactured by integrating the advantages of domestic and foreign double disc grinding machines and combining the specific conditions of the horizontal axis through-type double disc grinding machines. The outstanding characteristics are good stability, low energy consumption, high precision, low failure rate, easy maintenance and so on. It can grind two end faces of round, square, rectangular and other parts with different shapes and materials.

Product Details

Features and advantages:

1. The bed of the double disc grinding machine is designed with heat insulation to ensure that the machine can work continuously for a long time without affecting the accuracy.

2. The feed mechanism of the double disc grinding machine adopts high precision ball screw, and the guide rail adopts V-shaped steel inlaid needle roller bearings.

3. The grinding head of the double disc grinding machine adopts the an integral movement, so the rigidity of grinding is strong and stability is outstanding.

4. The fast forward, fast backward movement of the grinding head and the pretightening force of the grinding head of the double disc grinding machine are maintained by hydraulic pressure, which is reliable and safe.

5. The dresser of the double disc grinding machine is an independent integral structure with sufficient rigidity and high dressing precision. The two grinding wheels are automatically dressed at the same time.

6. The grinding wheel cover of the double disc grinding machine is automatically lifted and lowered. Each working unit is provided with safety interlocking.

The safety factor is reliable.

7. The double disc grinding machine has a compact layout and a scientific and reasonable design. The spindle box has good sealing. The service life is long. The operation is simple and maintenance is convenient.

8. The double disc grinding machine adopts double roller rubber belt feeding mode. The friction coefficient is large, the grinding strength is strong. There is no slippage. It is the most ideal machine tool for grinding various specifications of workpieces on a single machine.

9. The double disc grinding machine can be equipped with frequency converter to achieve stepless speed adjustment of the grinding head and realize differential grinding.

10. The double disc grinding machine can be equipped with servo motor and touch screen for numerical control.
