Abstract
The invention provides a grinding process for a high-precision steel bearing ball for an automobile. Due to the grinding process, the technical problems of scratches and burns on the surface of the steel ball, slot blockage, dead-angle balls, low production efficiency and difficulty in cleaning generated during the initial grinding production of the steel ball are solved effectively, the production quality and the grinding efficiency of the steel ball in the initial grinding process are guaranteed, and the process step comprises grinding the steel bearing ball by using circulating liquid and white corundum micro powder. The grinding process for the high-precision steel bearing ball for the automobile is characterized in that the steel ball is grinded by changing the circulating liquid for hard grinding liquid and a trace of white corundum micro powder on the same equipment in the process of grinding the steel bearing ball by the circulating liquid and the white corundum micro powder.
Description
Technical field
The present invention relates to the technical field of bearing steel ball producing process, be specially the grinding technics of a kind of automobile with the high-precision bearing steel ball.
Background technology
Existing high accuracy automobile generally is to add the white fused alumina micro mist through the 3ML4780 grinder with the early grind technology of bearing steel ball, grinds with the water aqua type circulation fluid, because circulation fluid is an emulsion; A little less than the cleansing power, the iron foam that grinds appearance after cutting is easily attached to steel ball surface, so cause sphere to scratch easily; Burn, and stop up groove, producing ball lot diameter variation can not control; Even stifled ball when serious appears, and cause the dead angle ball, directly influence the precision of the ultra lappingout of next procedure; Cause the scattered error of steel ball by the gross big, reliability descends.Owing to reasons such as obstructions, the decline of steel ball rotation property, flow velocity slows down, and production efficiency descends simultaneously, and the cleaning performance of circulation fluid is also lower.
Summary of the invention
To the problems referred to above; The invention provides the grinding technics of a kind of automobile with the high-precision bearing steel ball; Effectively solved steel ball surface scuffing in the steel ball early grind production process, burn, stifled groove, dead angle ball, low, the cleaning difficult technologies problem of production efficiency, guaranteed product quality and the grinding efficiency of steel ball in the early grind operation.
Its technical scheme is such; A kind of automobile is with the grinding technics of high-precision bearing steel ball; Its processing step comprises that adding the white fused alumina micro mist with circulation fluid grinds bearing steel ball; It is characterized in that: adopting circulation fluid to add in the process that the white fused alumina micro mist grinds bearing steel ball, on same equipment, switching to hard grind liquid to circulation fluid and add micro-white fused alumina micro mist bearing steel ball is ground.
It further is characterized as: when adopting circulation fluid to add the white fused alumina micro mist bearing steel ball is ground the 70%-80% that accomplishes the total allowance of grinding step, on same equipment, switch the white fused alumina micro mist that hard grind liquid adds trace bearing steel ball is ground; Described white fused alumina micro mist is an alundum (Al.
In the above-mentioned technology of the present invention; Adopting circulation fluid to add in the process that the white fused alumina micro mist grinds bearing steel ball; On same equipment, switching to hard grind liquid to circulation fluid adds micro-white fused alumina micro mist bearing steel ball is ground; Utilize hard grind liquid cleansing power strong, the advantage that the deposition ability is strong has effectively solved the technical problem that the sphere quality that groove is stifled, the dead angle ball causes is unstable, ball diameter variation causes low precision greatly that produces during circulation fluid grinds; Effectively avoided bearing steel ball early grind production process middle (center) bearing steel ball surface to scratch, burn; And clean simply, conveniently, guaranteed the product quality of bearing steel ball in the early grind operation, improved grinding efficiency.
The specific embodiment
A kind of automobile is with the grinding technics of high-precision bearing steel ball; Its concrete steps are on a 3ML4780B steel ball lapping machine, to adopt two block casting iron pans; Adopt circulation fluid to add white fused alumina micro mist (alundum (Al) by conventional method and carry out aqua systemic circulation grinding; When grinding reaches the 70%-80% of total allowance, on same equipment, adopt to switch the method for grinding fluid, switch to the white fused alumina micro mist (alundum (Al) that hard grind liquid adds trace by circulation fluid bearing steel ball is carried out trace grinding.
Adopting circulation fluid to add white fused alumina micro mist (alundum (Al) by conventional method earlier carries out aqua systemic circulation grinding, makes bearing steel ball accomplish certain stock removal as early as possible.
Adopt circulation fluid to switch to the white fused alumina micro mist (alundum (Al) that hard grind liquid adds trace again and carry out trace grinding, improved the bearing steel ball precision of this operation, stable accuracy is in 0.15 μ m.
Adopt the grinding technics of automobile of the present invention with the high-precision bearing steel ball; Production efficiency has improved 15%-25%, and is prone to clean stifled groove, nothing burn, no dead angle ball, and the steel ball circulation is smooth and easy; For extraordinary condition has been created in final ultra lappingout processing; The precision and the sphere steady quality that make ultra lappingout ball are equivalent on same equipment, reach the effect of early grind I and early grind II simultaneously more than G10 level ball, improved the precision and the production efficiency of early grind ball greatly.
Claims (3)
