Magnetic square box

Magnetic square box is an important auxiliary tool in flat plate measurement,used for measuring and inspecting the parallelism,perpendicularity,and various positional errors of mechanical components in the three-dimensional marking of fitters.The square box is made of cast iron or steel and has six working faces,with a V-shaped groove on one of the working faces.

Magnetic square boxes are mainly used for inspecting and marking the parallelism and verticality of components.A square box is a specific six working face cavity cube made of cast iron or steel,with a V-shaped groove on one of the working faces.The environmental conditions for square box calibration are normal temperature and humidity.

The working surfaces of the magnetic square box must not have rust,scratches,cracks,dents,or other defects that affect the measurement performance.Non working surfaces should be sandblasted and painted with chamfered edges.There should be a label on the inner wall of the square box,indicating the specifications,dimensions,level,factory number,and manufacturer name.

Purpose of magnetic square box:Used for inspecting and marking the parallelism and verticality of components.

Advantages of magnetic square box:V-shaped groove with magnetic force,convenient to use.There is magnetic force on the upper surface,both sides,and the V-shaped surface,which solves the measurement of irregular workpieces.

Magnetic square box manufacturing,with the same angle on both sides of the V-shaped surface,easy to operate,and measuring the diameter of the V-shaped surfaceΦWithin 20mm.
