How improve accuracy of hydraulic manifold block machining

As an important part of the hydraulic system, the machining accuracy of the hydraulic custom manifold block directly affects the performance and stability of the whole system. Therefore, it is important to improve the accuracy of hydraulic manifold machining. Here are eight key aspects to improve the machining accuracy of hydraulic valve blocks:

1. Choose high-precision machine tools

High-precision machine tools are the basis for high-precision machining. The selection of machine tools with high stiffness, high stability and high-precision positioning performance can ensure the accuracy and stability in the machining process. At the same time, the machine is regularly maintained and calibrated to ensure that it is in better working condition.

2. Optimize the processing process

The optimization of the machining process is the key to improving the machining accuracy. By formulating a scientific and reasonable processing process and reasonably arranging the processing sequence, the accumulation of processing errors can be reduced. It can effectively improve the machining accuracy of hydraulic valve blocks. In addition, the appropriate cutting parameters should be selected according to the holding properties of the material to avoid excessive cutting forces and thermal deformation.

3. Strictly control the quality of materials

The quality of the material has a direct impact on the machining accuracy. Therefore, when selecting materials, we should fully consider their mechanical properties, thermal stability, corrosion resistance and other factors, and choose high-quality materials that meet the requirements. At the same time, strict quality inspection should be carried out before the material is put into storage to ensure that the quality of the material meets the processing requirements.

4. Apply excellent measurement technology

In the process of processing, excellent measurement technology is used to monitor and feedback the processing size and shape and position error in real time. It can find and correct machining errors in time and improve machining accuracy. For example, high-precision measuring equipment such as laser interferometers and coordinate measuring instruments can be used to measure the critical dimensions of hydraulic valve blocks.

5. Improve the accuracy of tools and fixtures

The accuracy of the tool and fixture has a direct impact on the machining accuracy. Therefore, high-quality tools and fixtures should be selected, checked and replaced regularly to ensure that their accuracy meets the requirements. At the same time, in the design and use of fixtures, the positioning stability of the workpiece and the consistency of repeated clamping should be fully considered to reduce the influence of clamping errors on machining accuracy.

6. Control environmental factors

Environmental factors such as temperature, humidity, vibration, etc., will have an impact on machining accuracy. Therefore, environmental factors should be strictly controlled in the processing process to keep the temperature and humidity in the workshop stable and reduce vibration interference. At the same time, for high-precision processing equipment, special protective covers and vibration isolation devices should be set up to reduce the influence of external factors on its accuracy.
