NOTE: The manufacturer reserves the right to modify the design, specifications, mechanisms, etc., to improve the performances of the machine without notice. All the specifications shown above are just for reference.
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 DC servo motor.
7.PROXIMITY SWITCH:
Provide built-in-type (hidden) proximity switch, features safe and easy operation.
8.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.
