Tag: linear scale

Linear scale is a measuring and feedback device that works on the optical principle of grating. Linear scale is often used in the closed-loop servo system of CNC machine tools and can be used for Linear or angular displacement detection. The measured signal is digital pulse, which has the characteristics of wide detection range, high detection accuracy and fast response. For example, in CNC machine tools are often used to detect the tool and workpiece coordinates, to observe and track the feed error, in order to play a role in compensating the motion error of the tool. Linear scale is composed of a scale grating and a grating reading head. The scale grating is generally fixed on the fixed parts of the machine tool, the reading head of the grating is installed on the moving parts of the machine tool, and the indicating grating is installed in the reading head of the grating.

With the general use of machine tools in the field of processing, the accuracy of products processed by machine tools has been continuously improved, the assistant of machine tools in the processing of the knife route precision products are also used in machine tools, the linear encoder is a kind of product which assists the precision of the cutter of machine tool. The linear scale, often used in CNC machine tool closed-loop servo system, can be used as linear displacement or angular displacement detection. In machine tools, it is often used to detect the coordinates of tools and work pieces to observe and track the error of the cutter, such as play a role in compensating the motion error of the cutter. CNC machine tool installed linear encoder, which can ensure the precision of machine tool and has a good auxiliary effect for CNC machine tool processing accuracy. Linear scale is often used with digital scale for milling machine, lathes, surface grinders, grizzly planer ang optical comparator.
