珩磨是用颗粒很细的油石和适当的润滑冷却液来加工工件的内孔或外表面的一种金属切削方法,它是采用“三块平板互研”的原理加工出精密的表面。工作时,珩磨机主轴带动珩磨头在工件的孔内不断地作旋转和往复运动,使油石沿径向逐渐张开来切削金属。如今珩磨加工不再是只用于减小表面粗糙度值的最终精加工法,也可广泛地用于切除较大余量的中间工序中。 Honing is a metal cutting method for machining the inner hole or the outer surface of a workpiece with a very fine grain of rock and a suitable lubricant for cooling. The honing process uses the principle of “three-plate mutual research” to produce a precise surface. Work, honing machine spindle driven honing head in the workpiece hole constantly rotating and reciprocating motion, so that the stone along the radial gradually open to cut the metal. Honing is no longer the only finishing method used to reduce the surface roughness, but it can also be used extensively in intermediate processes where larger allowances are removed.
