AD Series Sealed Angle Incremental Encoders For Milling Lathe CNC Machine

ISO9001 AD Series Of Sealed Angle Incremental Encoders For Milling Lathe CNC Machine

Angle encoder usually refers to an encoder with accuracy within ±5''~10'' and a line count higher than 5000. Angle encoders are used for high-precision angle measurement where accuracy is required to be within a few seconds.
The main application scope of the enclosed angle encoder: CNC turntable; C-axis of a lathe; gear measuring machine; high-precision industrial robot joints; astronomical telescopes, etc.

The main features of this series of products are: the measurement system has high precision, reaching the international advanced level of similar products, and the built-in bearing and built-in coupling eliminate the influence of the machine tool components and the torque generated by the rotational acceleration on the measurement accuracy;

The installation is simple, and the built-in coupling expands the axial installation range to ±0.5mm, reducing the difficulty of processing and assembling related accessories.

The enclosed angle encoder series adopts the principle of photoelectric scanning for measurement. Its measurement datum is a glass grating.
Smart uses the self-developed lithography process to make precision gratings, with a typical grating pitch of 10um. The grating line thickness is uniform and the edge is clear, which is the key to outputting high-quality incremental or absolute position signal.

Advantages of enclosed incremental linear encoders

The sealed incremental linear encoder measures the position of the linear axis without additional mechanical transmission. All feed mechanisms are included in the position control loop through the linear encoder, and the mechanical motion error of the control loop is detected by the signal acquisition and processing system. The linear encoder reads the head and corrects it from the control, potentially eliminating several sources of error:

1. Positioning error caused by thermal expansion of the ball screw
2. Game bug
3. Motion error caused by ball screw pitch error

Therefore, the enclosed incremental linear encoder is an indispensable basic technical resource for high-precision, high-speed processing machinery.
