How vacuum heat treatment of prototype model is carried out

The cooling medium used in the prototype is different, vacuum quenching can be divided into Vacuum Oil cold quenching, vacuum air cooling quenching, vacuum water cooling quenching and vacuum nitrate quenching. The main application of CNC prototype processing vacuum heat treatment is Vacuum Oil cold quenching, vacuum air cold quenching and vacuum tempering. To maintain the workpiece (Such as prototype) The excellent properties of vacuum heating, the selection and formulation of coolant and cooling process are very important. The prototype quenching process mainly uses oil cooling and air cooling. For the prototype working surface that is no longer mechanically processed after heat treatment, vacuum tempering is used as much as possible after quenching, especially the vacuum quenching workpiece (Prototype) , It can improve the mechanical properties related to the surface quality, such as fatigue performance, surface brightness, while corrosive, etc.

vacuum heat treatment technology is a new heat treatment technology developed in recent years, which has the features, it is precisely what is urgently needed in the manufacture of prototype models, such as preventing heating oxidation and non-oxidation, vacuum degassing or gas removal, and eliminating hydrogen brittle, thus improving the material (Parts)Plastic, toughness and fatigue strength. Factors such as slow vacuum heating and small temperature difference inside and outside parts determine the small deformation of parts caused by vacuum heat treatment process.

for the working surface of the prototype model that no longer performs mechanical processing after heat treatment, vacuum tempering is used as much as possible after quenching, especially the workpiece with vacuum quenching (Prototype model) , It can improve the mechanical properties related to the surface quality, such as fatigue performance, surface brightness, while corrosive, etc.

computer simulation technology for heat treatment process (Including organization simulation and performance prediction techniques) The successful development and application make the intelligent heat treatment of prototype model possible. Due to the small batch of prototype model production (Even single pieces) The characteristic of multiple varieties, as well as the high requirements for heat treatment performance and the non-waste products are not allowed, which makes the intelligent heat treatment of the prototype model necessary.

electroplating process: generally, it includes three stages: pre-plating, pre-plating and post-plating.

requirements for electric plating:

1. Between the plating layer and the matrix metal, the plating layer and the plating layer, there should be a good bonding force.

2. The plating layer should be detailed, flat and uniform in thickness.

3. The plating shall have specified thickness and as few pores as possible.

4. The plating layer should have various specified indicators, such as brightness, hardness and conductivity.

Deep Hole Drilling is better used to solve the problems of tool deviation, tool cooling and chip cutting in deep hole processing, processing quality and productivity have been significantly improved. Can be processed to 10 ~ Deep hole of 30. Deep hole processing machine tool, can use a special Deep Hole Drilling bed, can also be modified for ordinary lathe.
