Simple introduced the new type of bearing characteristics of the grinding process

Bearing is a kind of important modern machinery and equipment parts and components, its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of movement, and guarantee its rotation accuracy. Ordinary rolling bearings by the outer ring, inner ring, rolling body and adhere to the four local part. In bearing consumption, is the most complex, the machining process of grinding and about bearing grinding, one of the key working procedure in consumption, how to adopt new techniques, new technologies with high precision, high efficiency, low capital to complete grinding process, is the main task of the grinding. Below yida bohai embellish petrochemical simple introduced the new type bearing grinding process which features: one, the new characteristics of the bearing grinding ( 1) High-speed bearing grinding technology of high speed grinding can finish the pursuit of modern manufacturing technology progress of two of the purpose of the quality and efficiency, and in high speed grinding wheel in addition to should have sufficient strength, also needs to ensure it has good grinding performance ability obtain high grinding effect. （ 2) New type of bearing grinding with cubic boron nitride grinding wheel has good processing property, new type of grinding wheel manufacturing technology and finishing technology, such as the special oil bearing grinding machine and grinding is ceasing to technology promotion transformation in order to meet the progress of the grinding process. （ 4) Bearing grinding CNC numerical control technology in high speed and low speed can ensure positioning accuracy, able to complete jump, fast, finishing compensation, coarse to fine grinding, make the machine tool feed mechanism is greatly simplified, performance stable progress greatly. Second, the new type of bearing grinding plan ( 1) Bearing the clamping method in bearing grinding to the correction precision of large Angle of cylindrical and process after positioning, can prevent hole in the seat surface grinding axial runout. （ 2) Bearing the cutting cutting allowance allowance is the guarantee of high efficiency and high precision grinding of bearing is an important parameter, fine grinding allowance usually control at the micro level. （ 3) Bearing grinding tool choice modern grinding technology using high speed grinding, to ensure that the process of grinding wheel in the grinding chip not NianDu grinding wheel, insist on good self-sharpening. （ 4) Bearing grinding speed of workpiece rotary speed and the diameter of the bearing grinding appearance is related to the speed of the workpiece can produce larger cut marks and surface roughness of grinding, the influence of low speed grinding appearance causes ripples, residual stress increasing appearance, high speed grinding burn appearance provoked later. Three, new bearing grinding problem ( 1) Bearing accuracy problem bearing is mainly composed of machine tool accuracy, precision fixture precision grinding process parameters and comprehensive. So reasonable sure nc grinding machine tool coordinate, the position of the grinding wheel fixed coordinates is also an important parameter of the workpiece quality. （ 2) Bearing burn issues bearing grinding process parameters in the process of unreasonable or blank size precision of the control will appear the phenomenon of grinding burn, the main elements of the grinding burns with low linear velocity of grinding wheel, low cutting force, grinding wheel and workpiece appearance method to force big, etc. （ 3) Bearing crack problems when grinding parameter selection is not reasonable, the hole in the seat surface after grinding of grinding can produce crack or fine crack appearance, special surface crack in pressure chamber in here will make the seat in front edge produces cavitation, landed the bearing fatigue strength. Four, the selection of new type of grinding oil ( 1) Grinding oil extreme pressure performance of the special grinding oil containing sulfide extreme pressure antiwear additive ingredients, effective maintenance of the abrasive, progress and precision process. （ 2) Chemical properties of the grinding oil special grinding oil has good chemical stability, will not cause harm in the equipment, human and environment. （ 3) Grinding oil performance of other special grinding oil in viscosity, flash point, pour point and thermal performance are through strict test, in order to satisfy the demands of all kinds of craft.
