Square boxes, cast iron square boxes, square tubes, and magnetic square boxes are made of high-quality cast iron. After being formed by mechanical processing, they are manually scraped and chiseled. They typically have a cube structure with six working surfaces. Adjacent working surfaces are perpendicular to each other, while opposite working surfaces are parallel and of equal height. They are used for precision measurement and marking of workpieces, as well as for clamping workpieces during machining. Generally, one working surface has one or two V-shaped grooves for measuring shaft components and workpieces. The specifications range from 100-500mm, and special specifications can be customized. The general accuracy is Grade 1.
