1. Check the size of the main gear blank check addendum circle diameter for easy adjustment of the cutting depth when, to be adjusted according to actual addendum circle diameter of the pitch circle ensure proper tooth thickness. 2. The bad tooth spur gear setup and calibration have bad teeth shaft and disc-type blanks. If the shaft gear blanks, one end can be directly clamped by dividing head jaw chuck, tailstock other end to the top tight; if it is blank disc-type tooth spur gear reducer curriculum design, first gear blank sets stage spur gear reducer spindle defects, one end of the spindle indexing head caught in the jaw chuck, and the other end is the tail tip top tight. Correction gear blank is very important. First correction roundness, if roundness bad, will affect the size of the pitch circle tooth thickness; recalibration straightness, namely dividing head-jaw chuck center and tailstock center connection must go with Longitudinal knife parallel to the direction, otherwise milling out the teeth are inclined; the last correction level, namely the center to table indexing head-jaw chuck and tailstock distance from the center to the work surface should be the same distance from the spur gear reduction ratio of the number as well, If the height difference sizes, milling out the teeth have depth.
