CONTROL PANEL

GRINDING PROCEDURES

Maximum cycle downfeed: 9mm(0.45"), can extend to whole vertical(optional accessory-Digital readout set with feedback function) to meet special requirements. 

2-step grinding procedure control: Rough grinding 0.001-0.04mm(0.00005"-0.002"); finish grinding 0.001-0.009mm(0.00005"-0.00045") 

PRE-SET Spark out: 1-9 times 

Automatically table movement stops and wheel head rises up from surface of workpiece, after cycle grinding completed. 

Provide plunge & surface grinding modes. 

Vertical feed powered by double motors; Stepping motor for Auto-downfeed (Min. increment: 0.001mm, 0.00005"); AC motor for rapid & slow up/down.

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.
