Balance and improve the design of the handwheel

手轮电感测微仪的测头安装在刀架上, 将仪器置于单通道A 挡输入, 量程30m 。">Handwheel inductance micrometer probe mounted on the turret, the instrument in single-channel A block input , range 30m. And with the Central Plains meter factory recorder. Enter placed 10 m V block. After measuring the instrument calibration curve. There are 15 distinct Nanjing Machine Tool Plant High Hongyue second round was then tested on the curve a curve 3 . First grade in 60mm length requirement of a periodic waveform error DGBe comparison with the hand wheel inductance instrument .
        The analysis : Machine apron movement along the rail while the longitudinal feed handwheel turning the handwheel per revolution , resulting in a periodically varying waveform recording paper , indicating that the problem comes from the hand wheel turning system . The results found that the hand crank wheel balance weights no symmetric parts , remove the hand wheel to be tested again , too Curve 2 . Circumstances under which the opponent wheel re- balanced design and manufacturing, when put on the novice to 0. 0 1 4 mm, and the measured were within 0 .0 1 omm. Such dynamic testing method is simple and feasible , with good results .
        But in the test should note the following:
        1 inductor comparator and supporting the use of the recorder should be in order to reduce errors instrument itself should check before use and fully preheat ;
        (2) the test should be made a standard screw and drive the screw rotates synchronously at the lowest speed ; 3 sides try to avoid as much as possible live electrical voltage classes have greater volatility.
