Sensors and servo motors are core components in automation equipment. Although the parts may look small, dimensional accuracy, assembly consistency, and machining stability directly affect system judgment, positioning control, and overall operating performance.

JIN YI CHERNG, a precision turned components manufacturer and CNC motor parts factory in Taiwan, provides support from prototype development to mass production for a wide range of industrial components.

Through CNC turning-milling combined machining and Swiss-type turning processes, multiple operations can be integrated into a single setup, helping reduce cumulative tolerance errors while improving efficiency and dimensional consistency for complex and high-precision parts.

Machining Accuracy

1. What benefits come from stable machining precision?

Custom sensor components are used in detection, positioning, and signal feedback systems, where dimensional stability and consistency directly affect sensing accuracy.

In servo systems, positioning and motion stability are critical, and machining quality impacts overall control performance. A servo motor shaft is responsible for torque transmission and rotational stability, so precision machining is essential for reliable performance and durability.

• More accurate sensing position: keeps sensor alignment correct and reduces deviation
• Improved signal stability: minimizes fluctuation or misjudgment caused by assembly tolerance
• Reduced vibration and deviation: helps maintain smoother operation during high-speed movement

2. What issues can unstable precision cause?

• Sensing deviation in custom sensor components
• Unstable signal output from custom sensor components
• Incorrect system judgment
• Increased vibration during servo motor shaft operation
• Faster wear of servo motor shaft components
