In non-standard parts processing, there will be different understanding of high-precision processing and different definitions, so how to define the processing standards for non-standard parts processing?
The definition of precision machining of non-standard parts is the production processing of the dimensions or characteristics of individual steel parts in accordance with the process and process flow, including the flatness of the steel parts, the surface finish layer, the flatness of the surface layer, the strength of the surface layer, so that the production and processing of the parts are possible. Accuracy and production processing performance exceeds the full range of engineering drawings specified.
Non-standard parts processing flatness regulations are the dimensional tolerance regulations around the rectangular frame steel parts and other non-standard high-precision machined steel parts, the thickness of the four corners of the specified steel parts over a certain range of dimensional tolerances. If the precision measurement of the thickness of the four sides does not meet the dimensional tolerance requirements, it does not meet the flatness requirements, and the steel part needs to be readjusted. The problem will be in the glass suction cups of CNC grinding machines, which are damaged by excessive applications, causing deviations in flatness. It will be the grinding wheel piece is not rectified, or the grinding wheel piece is broken, this time hardware non-standard parts processing also need to replace the grinding wheel piece, but also again to clear the glass sucker, carefully remove the neat, to prevent the emergence of burrs.
Non-standard parts processing of flatness regulations, that is to say, the provisions of the side of the steel parts and road surface over the size tolerance regulations. Understand that is to say the cube, from the number axis seems to be divided into XYZ three sides, the general provisions of XZ, YZ exceed the size tolerance provisions. Appear deviation also and flatness provisions of basically the same. In the non-standard high precision machining flatness regulations generally in accordance with the provisions of the flatness to solve can.
