Description
Based on precision surface grinder, it cover the longitudinal and vertival machine to fully automatic the bidirectiional friction eletronic clutch, simple and reliable structure, clutch reversing process has no impact, no noise, safe commutation 5000000 times; the electric control part with electronic switching frequency switching, the service life 10 times longer than the relay control, simple operation, sensitive, infinitely variable; large output torque, low noise, safe and reliable. Power supply use a number of machanical and electrical protection function which is safe voltage, energry saving, power saving, power consumption per class (cal according tp 8 hours) is only 0.6. When the manual grinding is working, before and after the workbench’s movement, in and out, around the reversing are automatic operation, greatly improving the production’s efficiency and the surface finish, suitable scope that from the original single, samll batch to mass batch.

Main Features
1. Precision grinding built-in electro spindle runs in maintenance-free, supported by preload high precision angular ball bearing.
2. The small surface grinder machine bed, table and column are high grade casting pieces, which supply strong base for grinding. The slideway is coated with TF wearable material and manually precision scrapped.
3. Hardened steel guide way and rolling ball (made in Taiwan) structure is adopted on the X axis, with smooth motion, high accuracy, and long life.
4. High precision cross and vertical lead screws are made in Taiwan.
