              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.
