Accessories / Special Features
Machine is suitable for workpiece length up to 2.000 mm
with a basement extension
* A cone shaped grinding wheel is employed, but it is only in line contact
with the centrehole surface, in addition it is reciprocating
simultaneously along this line.
The workpiece remains stationary, enabling the generation of perfect
centre holes.
* To clamp cylindrical Workpieces one uses a height adjustable 2 jaw vice
which gives three point contact and always coincides with the center of
the grinding spindle.
* Height-adjustable workpiece centering vice with carbide inserts.
Manual adjustment of appropriate workpiece diameter with clamping screw.
* Dressing device, mounted on the side of the grinding spindle, stroke
approx. 40 mm, for producing a geometrically exact conical form and with
oscillation of diamond tool.
* Pre-centering device for Workpiece adjustment between centers.
* Pneumatic Oil Lubrification of grinding spindle by oil-mist.
* Manually adjustable Tailstock with handwheel but without motorized drive.
Condition : Good to very good. Machine can be inspected under power.
Delivery : Ex stock, as inspected
