How to promote superfinishing process to improve the quality of the stainless steel bearing

We know that the action of the ultra precision of stainless steel bearing quality, how do we to improve superfinishing process technology? Numerous group of friends in the discussion, put forward a variety of problems, I make a summary to roughly the following points, and can only be general answer ( For reference only) What kind of superfinishing machine: 1, to use? （ ) And precision grade depending on the type of product model and asked to choose appropriate superfinishing machine, it is the choice of superfinishing method; 2, the consistency of the precision of the grinding process? This problem is complicated, later can open topic discussion of grinding process, how to ensure the consistency of the grinding process; 3, superfinishing replace quantity generally? Product model and different kinds of ultra precise general is not the same; Cutting quantity (such as miniature stainless steel ball bearing Replace the amount) 0. 008-0. 010毫米; And small stainless steel ball bearings that the amount of cutting generally to be 0. 010-0. 015毫米; The principle of cutting volume, remove the grinding cuticle, superfinishing race after the destruction of accuracy; 4, the use of oil stone to match? （ CBN abrasive? ） This is according to the requirements of you want to achieve goals and product characteristics to choose appropriate oil stone; Method is different, want to choose the materials will be different; For batch big, grinding stability good product, can choose the CBN abrasive; 5, selection of super oil? （ Aviation kerosene, special essential oil) As long as the cooling effect can meet the needs of operation, in that it doesn't matter, really, of course, the professional essential oil cutting ability are much better than jet fuel; Before not offering professional super essential oil, kerosene and rust-proof oil in ultra precision; So don't choose the so-called professional; 6, cooling, filtering system of technical parameters can meet? This difficult to define, typically control product produced no burns, control the pressure of the machine parameters, etc. Single filter system can detect the super oil dirty content, but the control cost is higher; What is the difference between July and super finishing and polishing? Is to reduce roughness, both work in a different way, the result is also different. After superfinishing surface, like a completed highway, from the bottom to the surface are level reasonable; And polishing is like as a child of the road, just on the surface pressure strong, very light, without any modification level; In the process of stainless steel bearings, also have a deburring polishing and light polishing process; 8, roughness control? Roughness control according to different kinds of products, according to different needs to choose suitable roughness value control; In general the bigger product model roughness value of the products; For small products, Ra general control in 0. 025 - 0. 03. The adjustment? The different product types, superfinishing differently, need to adjust the methods are also different; 10, straight grain and checker which good? Different equipment, different methods of grain is different, but the two lines can be, don't choose the superfinishing way, as long as the value of the roughness can meet the requirements, two are; 11, sometimes the light and dark, white spots, broken wires, snowflake point, etc. ? These appear the phenomenon of a lot of time with the abrasive material, grain number you choose, the more time on your production and processing of process parameter selection has a lot of link; 12, the product of the stability of the material and heat treatment process? Stainless steel bearing material and heat treatment process is extremely important, bad will directly affect the quality of the ultra precision heat treatment. There may be a lot of problems not summary, because the ultra lapping is really many factors involved, sometimes also is very complex. Therefore, for each enterprise according to the requirements of their products to choose a different machine, oil stone, essential oils, etc. , but some of the basic conditions must be done well. Here we just want to suggest these aspects for reference only, and only in the analysis, research, exploration and practice, to find out a product to adapt to the different characteristics of demand of superfinishing process.
