The instrument used to detect shaft, disc-type high-precision parts of the radial, circular and oblique end of the round beating beating, high precision, with a pair of Mohs 4 # hard top, improve the accuracy of deflection measurement instrument , increases the lateral parts by weight of the support. Surface design accurate and reasonable, to run operations from top to bottom rack, front and rear, left and right freely adjust the smooth, easy operation, the table frame steel is good, to improve the detection sensitivity of the instrument, especially for grinding products. 

 Main technical parameters: 
 1, radial rotary precision 0.001MM 
 2, side rails at length on the two vertices connected parallel 0.004MM (A05 type) 0.007 (A08 type) 
 3, the measured maximum diameter 400MM parts 
 4, the maximum length of the tested parts 500mm, 800mm
