GENERAL FEATURES

1.Column

Enlarged, honeycomb-ribbed column especially suitable for heavy duty grinding.

2.Construction

Construction of table, saddle and base is casted with high grade iron, strongly ribbed.

3.Spindle

Enlarged spindle set is supported by four preloaded precision angular contact Ball bearings for heavy duty.

4.Slideways

Vertical, cross (double vess) and longitudinal (one vee &one flat) slideways are coated with Turcite-B, provides stable movement and durable accuracy.

5.Automatic Continuous Lubrication System: 

All slideways and screws are fully oiled by automatic continuous lubrication system to eliminate wears on slideways & screws.

6.Cross Feed: 

Ball screw for cross travel, powered by AC motor.

7.Hydraulic Table: 

Table speed ranges 5-25m/min. With rack and pinion table drive for hand operation.

8.Proximity Switch: 

Provide built-in-type (hidden) proximity switch, features safe and easy operation.

9.Table Speed Control: 

Presettable hydraulic table speed control allows operator to pre-set speed rate, enable to get same speed rate when engaging hydraulic table every time.

10.Hand Wheels: 

Zero-setting slip-ring with vernier on vertical handwheel, and vernier on crossfeed handwheel.
