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.
