1. New style, 2. PLC control, 3. Touching screen panel, 4. Excellent quality, 5. Column moving type surface grinding machine - details see: https://www.machineto.com/new-style-large-size-surface-grinding-machine-10126508

Features:

1. Double walled column construction, providing high rigid support. Adoptcounterweight balance, making the machine moving stably, and reducingthe load of the ball screw, keeping the accuracy for long time.

2. Adopt rectangular guideway coated with ZA30-C zinc-based alloy, toget low friction coefficient, good abrasive resistance and high rigidity.

3. Adopt the Flat-V type guideway to set good guidance quality onlongitudinal and transverse, precision scraping to keep stable workaccuracy by hand.

4. The transverse and vertical movement are driven by AC servo motor, and the electronic hand wheel (MPG) instead of the tradition mechanical hand wheel, to get high accuracy and easy operation.

5. The independent and large capacity integrated hydraulic station equipped with air cooling and pressurizer, isolate heat and vibroseis, to provide excellent power for precision grinding.

6. The wheelhead spindle use the hydrostatic bearing with highrigidity (high precision ball bearing for export), which can provide thepower force together with 18.5kw motor, suitable for the heavymachining. The spindle rotary is supported by rigidity oil layerwithout wear; ensure the high precision and long life span.

7. Hydraulic drive for the work table, after adjusting meticulously, the table moved stably with little impact.

8. Adopt SIEMENS touch operation panel. It makes the operation simple and interesting by using power and friendly human-machine interface.

9. Special design, elegant appearance, good stability.
