Equipment used in industrial production for measuring the parallelism and perpendicularity of parts, magnetic square box It can also make underlines at key positions based on test results, being an essential tool in measurements. It features: non-deformable, strong, and more. It maintains stability under heavy loads and general temperatures.
Magnetic square boxes are used for inspecting or marking any angle line on workpieces, suitable for measuring and marking fixtures. They are widely used to support workpieces during the inspection of parallelism and perpendicularity of parts and for marking lines, usually in the form of cubes or rectangular prisms with equal side lengths. Customized specifications and equal-height square boxes and rectangular cylinders can be produced according to customer requirements.
Advantages of Magnetic Square Box:VThe slots are magnetized, allowing the workpiece to be securely fixed for measurement. Add accuracy. Generally, the service life of a magnetic square box is long, as long as it is used and stored correctly, the precision of the working surface of the square box can be maintained throughout its use.2Over one year, when the precision of the square box decreases, it can be restored through debugging or scraping and finishing processes. The service life of the square box itself can reach50-100Year, therefore, during the use of the square box, it is important to avoid using and storing it in damp, corrosive, excessively high or low temperature environments. This will help extend the service life and working quality of the square box. There may be some discrepancies between the appearance, size drawings, and actual dimensions of the square box, such as the length, width, height, and diagonal, which are generally within...±0.02(aOrbBetween... The usage method and materials of the magnetic square box are similar to those of the cast iron square box. The difference lies in...VThe groove and bottom are both magnetic, securely fixing the measured workpiece to the box for convenient use; it also reduces the risk of workpiece slipping and causing injury to the staff due to instability of the workpiece or negligence during operation. Technical requirements for the box: The work surface must not have any defects such as sand holes, air holes, cracks, inclusions, shrinkage, scratches, dents, rust spots, etc., that significantly affect appearance and performance, as these can lead to inaccurate measurements. Magnetic box manufacturing,VBoth sides of the profile have identical angles, easy to operate.VDimensional measurement diameterΦ20mmInside.
Magnetic Square Box Specifications:mm) 100×100×100、 150×150×150、 200×200×200、 250×250×250、 300×300×300
Advantages of Magnetic Square Box:
1.No deformation, strong
2.Abrasion-resistant, maintenance
3.Physically stable, tightly organized, grain detachment on impact, non-abrasive surface finish, and unaffected planar accuracy—Granite measuring platforms, with their work surfaces easy to maintain and care for during use, are stable in material, long-lasting without deformation, have a low coefficient of linear expansion, and are mechanical, rust-proof, magnet-proof, and insulated.
Calibration Method:
For sides of315mmAnd the following square boxes, when inspected, place one at each end of the surface being inspected on the square box.1mmCalipers are placed on the work surface of the block, with the blade straight rule placed on the work surface, then the block is tested at each inspection point. The difference in size between the block just inserted and the size of the blocks at each end is the deviation of the inspection point between the two ends. This check should also be performed on several cross-sections of the work surface in the longitudinal, transverse, and diagonal directions. When the direction of error is consistent in the straight lines measured at each position, the value is taken. When the direction of error is inconsistent, the sum of the positive and negative error values is taken, which represents the planarity of the tested plane.
