Grinding Spindles

Precision International offers Grinding Spindles, HF. These are internal grinding spindles. These spindles have the rotor produced with very special high-efficiency electrical laminations so as to provide more power within a compact body, and using hybrid bearings of ABEC9 quality. All components are hardened and ground; and all rotating parts are dynamically balanced to less than G 0.4 residual unbalance. The radial-runout and the axial- runout at the quill-mounting seat of the shaft are within 2 microns and 1 micron respectively. These spindles are available either as grease-packed (with reduced max speed) or with air-oil lubrication. These spindles are ideal for use in bore grinding or track-grinding of bearing-rings; for the grinding of auto-components; fuel-injection parts; gears; and others. The other range of products are grinding spindles both high frequency and belt-driven types; milling and boring spindles; external-grinding spindles; and precision ballscrews.
