How to improve the deformation of machined parts?

Workpiece deformation often affects the interests of the factory. Therefore, it is particularly important to avoid part deformation during part processing. It is particularly important to analyze the causes of deformation during part processing and improve processing methods and measures.

What are the improvement measures for machining deformation of mechanical parts?

1: Reduce the clamping force on the workpiece

When machining parts with poor rigidity, some measures should be taken to increase the rigidity of the parts, such as adding auxiliary supports. Attention should also be paid to the contact area between the clamping point and the parts. Different clamping methods should be selected according to the different parts. For example, when machining thin-walled sleeve parts, elastic shaft devices can be selected for clamping. Attention should be paid to the clamping position should be the position with strong rigidity. For mechanical parts of long shaft type, both ends can be positioned. For parts with very large length and diameter, both ends shall be clamped together, instead of “one end clamped and one end suspended”. In addition, when machining cast iron parts, the design of the fixture should be based on the principle of increasing the rigidity of the cantilever part. A new type of hydraulic clamping tool can also be used to effectively prevent the quality problems caused by clamping deformation during the processing of parts.

2: Use special clamps for different parts

For different parts, different special toolings are selected to prevent the parts from displacement during processing, so as to reduce clamping deformation.

3: Improve blank quality

Improving the quality of the rough embryo is the guarantee to prevent the deformation of the parts, so that the processed parts can meet the specific standard requirements of the parts and provide guarantee for the use of the parts in the later period.

4: Increase part stiffness to prevent excessive deformation

Combined with the performance of parts, appropriate heat limiting treatment measures shall be used to control deformation.

In actual operation, we should pay attention to every detail of machining and constantly improve the production process, which is also a process of increasing the experience of operators.
