Magnetic square box

Magnetic square box is an instrument used in industrial production to detect the parallelism and perpendicularity of components.

The use of magnetic square box: It is an instrument used in industrial production to detect the parallelism and perpendicularity of components. Magnetic square box can also make lines at important positions based on the detection results, and is an important detection tool in measurement. And it has the advantages of being resistant to deformation. Can maintain stability under heavy loads and normal temperatures.

The service life of a general magnetic square box is very long. As long as the correct methods are used and stored, the accuracy of the working surface of the square box can be maintained for more than 2 years. When the accuracy of the square box decreases, it can be restored through debugging or scraping processes. The service life of the square box itself can reach 50-100 years. Therefore, during the use of the square box, attention should be paid to not using and storing it in humid, corrosive, high and low temperature environments, so as to extend the service life and work quality of the square box. There may be some discrepancies between the design and actual appearance dimensions of the other party's box, such as the length, width, height, and diagonal lines of the square box, which are generally within ± 0.02 (a or b).

Usage and materials

Similar to cast iron square boxes, the difference is that the V-groove and bottom of the magnetic square box have magnetic force, which allows the tested workpiece to be firmly fixed on the square box, making it easy to use; At the same time, it also reduces the risk of workpiece slipping and injuring workers due to instability or negligence during operation.

Technical requirements for magnetic square box: The working surface must not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage, scratches, bumps, rust spots, etc. that seriously affect the appearance and performance of use, otherwise it will result in inaccurate measurements.
