Cast iron square ruler is a tool for checking the verticality of machine tools, mechanical equipment, and components. It is also an important measuring tool in the mechanical industry for installation, processing, positioning, and marking. Its characteristics are good stability and easy maintenance.
Cast iron square ruler is manufactured and mainly used for inspecting and marking the right angles of parts. When installing and repairing equipment, it is used to inspect the verticality of the relevant surfaces of parts or components. Before use, a staff member must install and debug the cast iron square ruler before it can be used. Working on a cast iron square without proper installation and debugging is meaningless. Installation and debugging by non-technical personnel may damage its structure and even cause deformation of the square, rendering it unusable. The installation and debugging of cast iron angle rulers by non-technical personnel is a violation of regulations and cannot be used.
