¡¹GENERAL
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. | | |
