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.
