Detailed analysis of machining methods and processes for mold parts

Mold parts processing methods and processing technology is today’s V1machining to bring you the knowledge, many people do not know how the mold parts are processed out, he mainly used washing processing, grinding processing, planing processing and other methods to process, the following look at it.

  Mold parts processing method

  1, washing processing: mainly with milling cutter milling processing of the plane

  2, grinding processing: mainly with a grinding wheel blade to the surface of the workpiece grinding processing.

  3, planing processing: mainly with a planing knife on the surface of the workpiece for planing processing.

  4、Special processing: It is the method of processing directly by using electric energy and chemical energy, etc.

  5, CNC machining: mainly through digital information to control the machine tool, so that the machined parts and the relative motion between the tool to meet the requirements, from the surface to achieve the processing of parts.

  Mold parts machining process

  1, geometric shape accuracy The geometric shape accuracy of the journal (roundness, cylindricity), generally should be limited to the diameter tolerance point range. When the geometric shape accuracy requirements are high, the allowable tolerances can be separately specified in the part diagram.

  2, surface roughness According to the different surface working parts of the parts, there can be different surface roughness values, such as ordinary machine tool spindle bearing journal surface roughness of Ra0.160.63um, with the journal surface roughness of Ra0.632.5um, with the increase in machine speed and precision degree of improvement, shaft parts surface roughness value requirements will also be increasingly small

  3, dimensional accuracy The journal is the main surface of the shaft parts, it affects the shaft rotation accuracy and working condition. The diameter accuracy of the journal is usually IT69 according to its use requirements, and the precision journal can reach IT5. 4, position accuracy mainly refers to the coaxiality of the mating journal of the assembled transmission parts relative to the bearing support journal, which is usually expressed by the radial runout of the mating journal to the support journal; according to the use requirements, the specified high precision shaft is 0.0010.005mm, while the general precision shaft is 0.010.03mm. In addition, there are coaxiality of inner and outer cylindrical surface and perpendicularity requirement of axial positioning end face and axis center line, etc.
