Deflection tester is mainly used for testing shaft, disk parts of the radial, circular runout and face runout, new product design, elegant, high precision, the operation very new runout inspection instrument with a pair of letters Mohs hardness of 4 # top, improve the accuracy of the measuring deflection, increasing support for the part is the weight of the radial measure precision parts, end and oblique round beating. Table frame compact design is reasonable, from top to bottom, front, left and right freely adjust the smooth operation, the table frame steel is good, improve the detection sensitivity of the instrument. For the convenience.
