Klein zss Center Hole Grinder

 Klein zss Center Hole Grinder Plunge grinding for center holes. Center holes from Accuracy Grinding accuracy as measured at the center hole is 1mm.

The roundness of a workpiece depends on the roundness of its center holes. Defect and Function of center hole Together with the dead center point, center holes must be ground before they are mounted on the external grinder, the center hole forms a plain bearing. For optimum results, the taper of the center hole must be round and co-axial with the center hole at the other end of the workpiece. After hardening the workpiece, its center holes are neither round nor oval, are out of alignment, covered with scale, and too rough. To obtain good results rapidly in circular grinding - essential for productivity - the center hole needs to be concentric with the outer center holes. The work-piece is held by hand during the plunge grinding process. This is uncomplicated and very quick. The grinding point plunges into the center hole and laps it round and coaxial. The grinding contact pressure can be adjusted by a spring. This ensures smooth and sensitive grinding of the smallest center holes. Grinding accuracy: roundness measured at the center hole is 1μm or better.

Grinding capacity: 1-120mm dia width of chamfer 2mm.

If the center hole must be concentric with the outer dia, or must be offset, then they are ground to the linear grinding method on the machines.

The workpiece stop is employed for prelocating the workpieces and as a hand support during grinding. Plunge grinding: Dust collector 3-phase 400 V for a bright working area. Standard Special Selection of cone pulley sets Largest center D in mm Grinding wheel speed rpm
