Case Study: Protective Coatings Reduce Maintenance Costs by 30% on Hydraulic System Maintenance

Challenge: A construction machinery company's customer had hydraulic valve cores made of 42CrMo steel. The performance of the hydraulic valve cores had been compromised due to wear and tear after an average of 300 hours. The maintenance cost was as high as $150,000 per year.

JS Precision Solutions:

1. Material Upgrade: Changing the original material 42CrMo steel to a powder metallurgy steel, which is more wear- resistant and therefore improves the intrinsic performance of the substrate.

2. Protective Precision CNC Turning: Precision CNC turning of the dimensioned parts and then applying low, temperature PVD coating technology to deposit a high-hardness wear-resistant coating on the surface of the precision, turned parts.

3. Precision Guarantee: Use of precision testing instruments to ensure that the parts' accuracy is strictly controlled within 0.005mm after coating, as per the drawing requirements.

Results: The improved hydraulic valve core has an MTBF that has been surpassed 1200 hours, hence the maintenance costs have been reduced by 30%, and the equipment reliability and production efficiency have been increased by 25%.

If your parts face challenges related to wear resistance, corrosion resistance, or other protection issues, consider JS Precision's protective precision CNC turning service.

How Are Vibrations Controlled In The CNC Turning Process For Flawless Surfaces?

Vibration is the main factor affecting surface smoothness and machining accuracy in the CNC turning process, especially for high-precision part machining. Effective vibration control is crucial. At JS Precision, it is ensured that the machining process is stable and accurate through multi-dimensional technical means.

Vibration Control Strategies:

1. Process Optimization: Experienced engineers use validated cutting parameters based on the characteristics of materials and structures of machined parts to avoid "chatter" phenomena that occur during machining.

2. Dynamic Stability Technology: The use of high-end machine tools with active damping systems or hydrostatic guideways makes it possible to identify and eliminate machine vibration during machining, thus increasing the rigidity of machine tools.

3. Tool and Fixture Strategy: The use of vibration-damping tool holders makes it possible to avoid tool vibration, meanwhile, it is possible to shorten the overhang length of the workpiece by designing workpiece fixtures with optimal rigidity.

4. Real-time Monitoring and Adjustment: The machining process is monitored in real time with vibration sensors. Once abnormal vibration is detected, parameters are adjusted to ensure machining stability.

With the above exhaustive steps, we are able to produce the mirror finish turned surfaces with Ra values less than 0.4μm in the CNC turning operation. The accuracy in the machining process meets the international standards for high-end manufacturing, as defined in the ISO 2808 standard for surface roughness.
