T-shaped groove square box

Service life and precautions of T-shaped groove square box:

The service life of a typical T-shaped groove square box is very long. As long as the correct methods are used and stored, the accuracy of the working surface of the T-shaped groove square box can be maintained for more than 2 years. When the accuracy decreases, it can be restored through debugging or scraping processes, and the service life can reach 50-100 years. Therefore, during use, it is important to be careful not to use and store it in humid, corrosive, high and low temperature environments, in order to extend its service life and improve work quality.

requirement:

Each working surface shall not have rust, scratches, cracks, dents, or other defects that affect the metrological performance. Non working surfaces should be sandblasted and painted, with chamfered edges. There should be signs on the inner wall of the square box, indicating specifications, dimensions, grade, factory number, and manufacturer name.

When selecting the flatness standard for T-shaped groove square boxes, it is generally determined according to the usage situation. Flat plates with a flatness above level 3 are used for inspection, marking, assembly, etc., while T-shaped groove platforms with a flatness below level 3 are generally used for riveting and welding.

The purpose of the T-shaped groove square box is mainly to inspect and mark the parallelism, perpendicularity, and other aspects of the components. It is suitable for various welding and assembly work, and is used as a reference plane for various product assembly and welding. It is used for machine tool mechanical assembly welding and other functions. It is also used as a T-shaped groove platform for inspection to check the dimensional accuracy or behavioral deviation of the parts. Most T-shaped grooves are designed with wire return spaces to facilitate the entry and exit of bolts and the cleaning of residues and other waste.
