At the same time, all components have been optimized through finite element force analysis, and computer dynamic simulation has been carried out, which has high reliability. The spindle box is specially developed for deep hole honing machines. Through the spindle box, pipe fittings within the processing range can be realized at constant power. The spindle box slide plate sliding device can make the spindle box and the honing tool easily removed from the processed hole after a honing cycle, which is convenient for hole inspection and measurement, convenient for replacing oilstones and workpieces, and keeps the honing head in a safe state to avoid scratching the workpiece. At the same time, for the same workpiece, the parameters of the stroke starting point and end point can be guaranteed to remain unchanged. For the next working cycle, there is no need to reset the parameters, which improves work efficiency.
