The present invention compares with existing High-speed machining handle of a knife measurement mechanism, has the following advantages:
(1) main 4 parameters of the handle of a knife of measurement high speed processing simultaneously, easy to use, efficiency of measurement is high.
(2) adopt high-resolution inductance amesdial (can reach 0.01 micron), measuring accuracy is high.
(3) measurement data shows through the digital display appearance, the value of the reading error of having avoided vision to produce.
(4) measurement data can be sent to computing machine, is convenient to measurement data and preserves and analyze.
