YRTM rotary table bearing with angle measurement system: Angular displacement measurement plays a crucial role in industrial applications, especially in the machine tool industry, where high precision is required for the rotation angle of machined parts. This necessitates accurate measurement and control of angular displacement.
Currently, commonly used methods for angular displacement measurement include optical encoders and magnetic encoders. Furthermore, because it is mounted on an ORT bearing, this combined shaft offers extremely high rotational accuracy and can simultaneously withstand axial loads, radial loads, and overturning moments. It is highly suitable for high-precision CNC rotary tables, machining centers, and demanding applications such as scientific research and measurement in the machine tool industry.
Advantages of the steel grid measurement system:
1. Non-contact inductive encoder, wear-free
2. Accuracy comparable to optical encoders, with a maximum accuracy ≤2
3. Dual reading head measurement system allows for real-time correction of bearing radial deviations
4. High speed, high dynamic performance, high resolution
5. No magnetic components, no hysteresis response, no demagnetization hazard
6. Strong resistance to environmental interference, IP67 protection rating, withstands certain water pressure and dust, insensitive to any type of pollution or dirt.
7. Compact design solves the problem of limited installation space.
8. Can output sine wave (1VPP) or square wave signal (TTL), compatible with Siemens and FANUC CNC systems.
