Although reducer can avoid step sense and oscillation partly, the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ), so plan to use step motor to drive the screw directly, the step motor at low velocity, which is not drived by the subdividing drive system, will have obvious oscillation and noise that would influence the cutting function, the usage life and sample structure
由於步進電機是通過皮帶輪減速來驅動絲杠，進而帶動砂輪片前進和後退，雖然減速能部分消除步進感和振動，但皮帶傳動會影響定位精度，定位精度對精密切割機十分關鍵的技術指標。採用步進電機直接驅動絲杠，未經細分驅動的步進電機在低速運行時，有明顯的步進感、振動和噪聲，從而對切割的性能、砂輪片的使用壽命、試樣的組織結構產生較大的影響。 -
