-High Precision Cast Iron Right Angle Square
-OEM offered

Abstract: the iron square according to standard GB6092-85, material HT200, mainly used for the orthogonal test and crossed parts, equipment in installation and adjustment, and inspection on the surface of the parts or components related to vertical degree. 
Cast iron square rule is applicable to the perpendicularity of the machine tools, mechanical equipment and parts inspection, processing installation location, line is an important measuring tool in mechanical industry, its characteristic is high accuracy, good stability and easy maintenance. Square is used for right Angle and draw vertical line detection tools, when installing a different mechanical equipment, it can also be used to verify parts surface location of the vertical degree and the accuracy of machine tools. Cast iron square according to standard GB6092-85, material HT200, mainly used for the orthogonal test and crossed parts, equipment in installation and adjustment, and inspection on the surface of the parts or components related to vertical degree. Cast iron surface and reference plane perpendicular square measurement, used for inspection right Angle, vertical degree and parallel degree error of measuring instruments, also known as the 90 ° Angle square.

Specifications: (non-standard products can be designed according to user requirements production)
