Cast iron square ruler

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. Personnel's installation and debugging may damage its structure, and even cause deformation of the square, making it unusable. Installing and debugging cast iron angle rulers is a violation of regulations and cannot be used.

Main characteristics of cast iron square ruler

1. The cast iron square ruler is lightweight: a 3-meter-long ruler weighs only 9kg.

2. Easy to use: 1 6-meter-long ruler that staff can easily move for measurement.

3. Not easily deformed: The bending point of general steel materials is 30kg 2, and the bending point of general castings is 38kg 2. The bending point of this material reaches 110kg 2, and the bending index far exceeds other materials.

4. Easy to store: can be hung or placed flat. It will not affect its straightness and parallelism due to long-term flat placement.

5. Not easy to rust: No need to apply oil during use. If not used for a long time, gently apply a thin layer of general industrial oil when storing. Parallel rulers are suitable for inspecting unevenness and straightness in machine tool testing, and the two working surfaces are inspected with instruments such as block gauges and level gauges. A measuring tool for measuring the parallelism of two guide rails at different heights and the level without connecting the guide rails, and for checking the perpendicularity of two components that cannot be checked with a square ruler alone. It is also suitable for equipment installation and inspection. The parallel ruler is a vertical tool used in measuring rooms and other length detection departments. It is made of granite and ground on the working surface. During grinding, a grinding wheel with stable accuracy, no deformation, no rust, and easy storage is required. It is an ideal detection tool.
