810X1600mm Large Sized Surface Grinding Machine (SG-81160FR)

Product Description

Column Moving Type NC Surface Grinding Machine
Large sized surface grinder(grinding machine) with PLC & HMI interface
Model: SG-81160FR, SG-81220FR, SG-81300FR, SG-81400FR
Features:
1. Double walled column construction, providing high rigid support. Adopt counterweight balance, making the machine moving stably, and reducing the load of the ball screw, keeping the accuracy for long time.
2. Adopt rectangular guideway coated with ZA30-C zinc-based alloy, to get low friction coefficient, good abrasive resistance and high rigidity.
3. Adopt the Flat-V type guideway to set good guidance quality on longitudinal and transverse, precision scraping to keep stable work accuracy 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 high rigidity (high precision ball bearing for export), which can provide the power force together with 18.5kw motor, suitable for the heavy machining. The spindle rotary is supported by rigidity oil layer without 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.
