High Precision Chemical Etched Encoder Discs For Motion Control Systems

Etched encoder discs serve as indispensable components in motion control technologies, delivering high-resolution positional and velocity data critical for precision-driven mechanisms.

Xinhaisen employs state-of-the-art chemical etching processes to fabricate encoder discs with micron-level accuracy, producing intricate optical patterns that capture rotational parameters with sub-micron resolution. These precision-engineered discs form the operational backbone of advanced servo systems across aerospace instrumentation, CNC machinery, semiconductor manufacturing, and automated guided vehicles, maintaining motion synchronization in mission-critical applications.

The Encoder Discs we etched:
Using photo chemical etching machining technique, Xinhaisen manufactures custom metallic encoder discs with customer’s drawings. So that we can fabricate metal encoder discs with a wide variety of precise patterns, such as, capacitive encoder disc, optical encoder disc, reflective encoder disc, and magnetic encoder disc etc.

Specifications of Etched Encoder Discs:

Etched Encoder Discs Applications:

• Automotive: Used in electronic steering, throttle control, and automatic transmissions for precise motion detection.
• Medical: Enable accuracy in MRI machines, surgical robots, and lab equipment for positioning and movement control.
• Aerospace/Defense: Monitor control surfaces (ailerons, rudders) in aircraft to ensure safe and precise flight adjustments.

Why Choose Chemical Etching to Process Encoder Discs?

1. Cost-effective: no expensive molding tool required.
2. Fast sampling: sample within 2-3 days, not weeks.
3. High precision, micro and complex.
4. No additional cost for complexity.
5. Burrs and stress free, no sharp edge.
6. Mass production within days, not month.
7. Various material options: stainless steel, copper, brass, aluminum, alloys, titanium and so on.
8. No effect on material temper or magnetism.
