High Precision Surface Grinder

Semi-automatic

ESG-3A1228

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.
