Usually, when programming a CNC machine tool, at least one reference coordinate point must be selected to calculate the coordinate values ​​of each point on the work chart. These reference points are called zero points or origins. Common reference points have mechanical origin, regression reference point, Work origin, program origin.

Machine reference point: A mechanical reference point, or mechanical origin, which is a fixed reference point on a machine.

Reference points: There is a regression reference point on each axis of the machine. The position of these regression reference points is pre-precisely set by the limit switch of the stroke monitoring device as the regression point of the table and the spindle.

Work reference points: The working reference point or work origin, which is the origin of the working coordinate system. This point is floating and is set by the programmer as needed. It is usually set on the workbench ( Work on) any location.

Program reference points: The program reference point or program origin, which is the reference point for the coordinate values ​​of all turning points in the work. This point must be selected when writing the program, so the programmer must select one when selecting. Convenient point to facilitate the writing of the program.

The steel telescopic rail guard is formed by cold pressing of high-quality 2-3mm thick steel plate, and can also be stainless steel according to requirements. Special surface finish will give it an additional value. We can provide the appropriate rail protection type (horizontal, vertical, tilt, lateral) for all machine types.

Steel shield

The structure of the shield we have developed varies depending on the operating speed and the guide rail. We run a polyurethane or brass slider below 10m/min. We have rollers under medium speed 30m/min. In addition, a buffer system is required between the drive plate, the scraper plate and the suction plate. The purpose of the slider buffer system is to reduce collisions, noise and friction.

The number of sections of the steel telescopic rail guard is important for its proportion, weight and operating characteristics. Each block should be as long as possible, which can reduce the number of sections and reduce costs. In general, the maximum stretch and minimum compression ratio should be between 3:1 and 5:1.
