Hardware non-standard parts processing processing precision machining is defined in accordance with the process and process of each steel part size or characteristics of the production process, including the flatness of the steel part, the surface finish layer, the flatness of the surface layer, the strength of the surface layer, so that the production and processing precision of the parts and production and processing process performance over the engineering drawings specified in the whole process.
To put it bluntly, the flatness of non-standard parts processing regulations refers to the dimensional tolerances around non-standard high-precision machined steel parts such as rectangular frame steel parts, specifying the thickness of the four corners. Steel parts over a certain size. Tolerance category. 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. The steel part needs to be readjusted. The problem can occur with the glass suction cups of CNC grinders. The glass suction cup is damaged by overcoating, resulting in deviations in flatness. It will be that the grinding wheel is not repaired, or the grinding wheel is broken. At this point the grinding wheel must be replaced for non-standard parts machining and the glass suction cup must be removed again. Careful cleaning and finishing to prevent burrs.
Non-standard parts machining flatness requirements are the sides and pavement of the steel parts exceed the dimensional tolerances specified, my understanding is that the cube, from the point of view of the number axis, is divided into three sides of XYZ. Generally, XZ and YZ are specified to exceed the dimensional tolerances specified. The deviation is also basically the same as the deviation specified for flatness. In non-standard high-precision machining, flatness requirements are generally addressed in accordance with the flatness regulations.
