Square box

Square box, square box, square box, universal square box, contour box, rectangular box, T-slot square tube, T-slot square box, cast iron square box, rock square box, large square box
It can be used for inspecting or scoring arbitrary angle lines of precision workpieces. According to user requirements, various specifications and contour boxes, rectangular tubes, T-slot square boxes can be produced.

The square box is manufactured according to the JB / T3411.56-99 standard. The material is HT200. It is used to check and score the parallelism and perpendicularity of parts. The universal square box is used to inspect or scribe any angle line of precision workpieces. It is required to make various specifications and contour boxes and rectangular tubes.
Cast iron square boxes are mainly used to support parallelism and perpendicularity of components and support workpieces during scribing. Generally, they are cubes or cuboids with the same side length. Various specifications and contour boxes and rectangular tubes can be made according to user requirements.

  1. Uses: The square box is mainly used for checking and marking the parallelism and perpendicularity of parts. The square box is a hollow cube with 6 working faces made of cast iron, one of which has a V-groove. The environmental conditions of the square box inspection: normal temperature and humidity.
  2. Requirements : The working surfaces of the square box must be free of rust, scratches, cracks, dents and other defects that affect the measurement performance. Non-working surfaces should be sand-painted and chamfered. There shall be a label on the inner wall of the square box, and it shall be marked with the specifications and dimensions, the class ex-factory number, and the manufacturer name.
  3. Accuracy: Generally divided into three levels : level 1, level 2, and level 3.
  4. Square box verification method: For square boxes with a side length of 300mm or less, place 1mm measuring blocks at each end of the tested surface of the square box, place the knife edge on the working surface of the measuring block, and then At the check point, the test block is tested with a block. When the block group is just inserted, the difference between the size of the block and the size of the block at both ends is the deviation between the two ends of the inspection point. This test shall also be carried out on several sections of the square box working surface in the longitudinal, transverse and diagonal directions. The maximum value is taken when the error directions in the measured straight lines at the respective positions are consistent, and the sum of the absolute value of the maximum positive difference and the maximum negative difference when the error directions are inconsistent is the flatness of the plane of the inspection surface.
