Reasonable control of temperature during precision hardware processing

Reasonable control of temperature during precision hardware processing

The standards of precision parts processing industry are very strict, and there are different processes such as cutting in and cutting out in the processing process. The size will also have different specific requirements according to the product, and the processing accuracy requirements will also be different.

In general, the precision of precision machining requirement is very high, sometimes even accurate to 1mm below micron difference, if the size difference is very big, the product will become a waste, need to rework to meet the requirements, the process is very time-consuming and laborious, sometimes make all raw materials scrap, cause the increase in cost, at the same time parts must cannot be used, so precision parts processing is a lot of requirements.

In the process of precision hardware processing, the application of mechanical processing technology mainly has two categories: squeezing pressure and rubbing force, in order to effectively reduce the impact of external force on the accuracy of precision parts, it is necessary to control the impact of the above two aspects of the force.

On the one hand, before the precision machining work is carried out, strict inspection of processing equipment.

If the position of the fixed parts of the equipment is tight, timely adjustment measures should be taken, so that the force effect of the equipment on the precision hardware processing parts can be effectively reduced, on the other hand, due to the unavoidable friction on the surface of the precision machining equipment.

For example, based on the production of parts, precision parts and machine tools are in contact with each other, there will be the corresponding friction formation.

As the production work continues, the friction will increase, so it is necessary to summarize the daily inspection process of the equipment.

Polish its surface, so that the friction between parts and equipment contact is effectively reduced, and then make the accuracy of precision hardware processing parts is effectively improved.

In order to make the precision machining process of parts processing accuracy is effectively controlled, to control the temperature of the machining process.

Because the precision hardware processing equipment in the process of operation, it is easy to be affected by the temperature, whether the temperature is high or low, will affect the normal and reliable operation of the equipment, based on the actual processing period, if the running speed leads to high temperature, need to use cold water cooling method to treat.

For example: in the process of grinding precision parts, the grinding wheel rotating at a high speed on the machine tool will produce mutual friction between the parts, and then produce a lot of heat.

When the temperature is high, it will lead to the deformation of the parts in contact with the grinding wheel, and at this time, it is necessary to take the cold water cooling method.

It is very important to reasonably control the temperature during the application of the machining process.
