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. Pjdpfx Aovanrcjdwjpw * 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.
