Drill Grinder |
|
| |
Features:
- Rugged construction and precision
components assure accuracy.
- The six jaw chuck accurately centers
the drill which ensures that the cutting lips are ground equally
in both length and angle to produce drill, NC drill, step drill,
taps, endmill, counter sink, round bars, etc.
- Grinding wheel and "dish"
grinding wheel are both on spindle to save time.
- Grinding capacity:
UDG-60: ø0.07"~ø2.36"
(straight & taper shank)
UDG-100: ø0.20"~ø3.94" (straight & taper shank)
- With 6" precision jaw chuck,
it can grind the table of the drills and the paring of the drills
abdomen.
- The main spindle has 2 grinding
wheels. It can grind the blade and the center of the drills at
he same time. This can save time without changing the grinding
wheel.
- The motor can travel 6.30"
up and down. This can increase the control of the machining.
