Engineering machinery fittings grinding technology:

one: Longitudinal feeding and longitudinal feeding speed

Every turn (or stroke workpiece wheel rotation axis) along the longitudinal and distance to feed, called | s longitudinal said, its size, the percentage of the degree of calculating unit for ram/r. Usually, the size of the longitudinal feed for longitudinal = (o. 2-0.85), June 6 sand type sand grinding ITllTt width (for). For example, grinding wheel, when feeding 40mm width is o. 3b sand, workpiece rotate a week, workpiece axis movement distance.

two: workpiece speed

The circle and the hole by grinding workpiece grinding, any point on the surface of each minute in the distance, called the workpiece speed, mouth, said unit work for m/rain. 丌 d work in ns, type, the workpiece work d or hole diameter (n actions), Anyone - workpiece speed (r/rain). In grinding, FAG bearing grinding workpiece speed is much lower than the rate for the proportion approximately v22 / v) = 1/60 ~ 1/80, coarse grinding workpiece should take some high speed and fine grinding workpiece speed should take some low speed, workpiece is generally 30 ~ 60re/rain. In actual production, general diameter workpiece is known, workpiece speed should be selected according to the process conditions.

Three:Wheel speed

The surface grinding any point in unit time passes away, called the wheel speed, using ", said the unit for sand m /. According to the diameter of the grinding wheel and speed, speed is obtained under the type used in the sand: type - wheel diameter (D); n sand - mHl grinding wheel (r/rain), high grinding speed. The maximum depends on the type and grinding machine with the rigid. General grinding speed in 35 ~ 50m/s.

When the bearing grinding FAG, grinding dosage of the choice is very important. So-called grinding dosage, refers to the grinding process and effect of processing of several directly related standard, which includes cutting speed, speed, workpiece feeding speed grinding, longitudinal horizontal or vertical feeding (optimizing, etc.). Reasonable choice of grinding grinding quality and productivity has very big effect. Outside round and round below grinding, for example, to illustrate the significance of various factors of grinding dosage.
