[0024] In this embodiment, the rear end of the clutch shaft to be ground is clamped and fixed by the centering clamp 12 when grinding the outer circle of the clutch shaft, at this time the centering hole at the front end of the clutch shaft is pushed against the elastic top rod 15 on the tailstock 14 in order to fix the clutch shaft, then the indexing motor 13 is started to rotate slowly, the outer diameter grinding motor 5 is started to drive the outer diameter grinding disc 6 to rotate at high speed, then the left slide 4 is slowly moved to approach the clutch shaft along the left guide rail 2, then the outer diameter grinding disc 6 rotating at high speed grinds the outer circle of the clutch shaft rotating slowly.

[0025] After the outer diameter of the clutch shaft is ground, the spline groove of the clutch shaft is made to be in the same plane with the notch grinding disc 9 by the indexing motor 13, at this time the right slide 7 is slowly moved to approach the clutch shaft along the left guide rail 2, then the notch grinding disc 9 can grind the first spline groove of the clutch shaft, after the first spline groove is ground, the right slide 7 is slowly moved to move away from the clutch shaft along the left guide rail 2, then the indexing motor 13 is started to rotate at a set angle, then the right slide 7 is slowly moved to approach the clutch shaft along the left guide rail 2 to grind the second spline groove, until all the spline grooves are ground; in this way, the outer circle surface and the spline notch of the clutch shaft can be ground in turn only by single clamping, which can improve the grinding efficiency and the grinding precision of the clutch shaft.
