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.
