Enclosed Linear Scale Direct Mounting: Real-Time Error Correction for CNC Axes

Linear Scale Advantages

When using linear scales for position detection of linear axes, no additional mechanical transmission components need to be installed. The linear scale is directly installed on the slide plate, and it can collect the errors generated by mechanical transmission in real time. These errors can be corrected through the control system. The product is of an all-enclosed structure. The aluminum shell can protect the grating, the scanning reading head and the guide rail, and isolate dust, cutting debris and other contaminants. The accompanying elastic sealing strips further enhance the sealing performance of the shell.

Measurement Principle

The linear scale adopts the incremental measurement principle. The ruler body is engraved with regularly spaced periodic grating lines. The grating pitch (measurement step) is a fixed physical dimension. The reading head counts the incremental number of lines passed during the movement and multiplies it by the pitch to calculate the total displacement, thereby obtaining the real-time position. Incremental gratings cannot directly output absolute coordinates. The count will be lost after power failure. Therefore, a single reference line is specially processed on the scale body. After the machine performs the zero-return operation and triggers the reference point, the system can calibrate the coordinate deviation, establish the mechanical origin, and eliminate the cumulative counting error.
