3 Overview
Square is a square used as vertical measurement of the angle measuring instruments, mainly used to check the calibration Squares and
Squares of the test, can also be used to do the inspection of metal cutting machine tools and some mechanical instrument shape error, position error.
Square Square its manufacturing accuracy can be divided into 000, 00, 0 and 1 four-level accuracy class.
Square Square is usually steel, cast iron or made of granite. Its structure can be divided into Ⅰ shape (as shown in Figure 1),
Ⅱ type (shown in Figure 2), Ⅲ type (Figure 3) three forms. Square Square generally upright use, the
Lettering on the front surface (surface lettering known as front side), rear side against the positioning fence (also known as the back side positioning surface) adjacent
Measuring the angle between two faces of the working angle (perpendicular to the plane of two adjacent measurement error, also known as the operating angle vertical error). Square
Square side length of its general value H as its model specifications, common specifications are shown in Table 1 square Square.
