GENERAL CHARACTERISTICS:
1. Column: Enlarged column with honeycomb ribs particularly suitable for intensive grinding.
2. Construction: The table, saddle and base are cast from high-quality, heavily ribbed iron.
3. Spindle: The enlarged spindle set is supported by four preloaded precision angular contact ball bearings for heavy-duty use.
4. Slides: The vertical, crossed (double bladder) and longitudinal (one V and one flat) slides are coated with Turcite-B, offering stable movement and lasting precision.
5. Automatic continuous lubrication system: All slides and screws are fully lubricated by an automatic continuous lubrication system to eliminate wear on the slides and screws.
6. Cross feed: Ball screw for transverse stroke, powered by an AC motor.
7. Hydraulic table: The table speed varies from 5 to 25 m/min. With rack and pinion table drive for manual operation.
8. Proximity switch: Provides a built-in (concealed) proximity switch, offering safe and easy operation. Speed control
9. Table: The pre-adjustable hydraulic table speed control allows the operator to preset the speed rate, enabling the same speed rate to be achieved when engaging the hydraulic table every time.
10. Handwheels: Zeroing slip ring with vernier on the vertical handwheel and vernier on the cross-feed handwheel.
