[0018] A discharge channel 13 is further provided on the machine body 1 , and the front end of each of the horizontal slideways 12 is connected to the discharge channel 13 , and both sides of the discharge channel 13 are inclined downward toward the outer side of the machine body 1 .

[0021] Furthermore, the output shaft of the motor 4 and the telescopic rod of the push cylinder 3 at each workstation are coaxially arranged, and the front ends of the two are opposite to each other.
[0022] Furthermore, the sliding mechanism includes a slide plate 8 and a slider 9. The slide plate 8 is fixedly embedded in a groove 14 set at the front part of the body 1.

After the blocking cylinder 2 is blocked, the push cylinder 3 pushes the bearing ring 10 at the bottom of the vertical feed channel 11 forward along the horizontal slide 12, and at the same time, the telescopic cylinder 6 is actuated to push the motor 4 across the discharge channel 13 to approach the bearing ring 10 through the sliding mechanism until both end faces of the bearing ring 10 are aligned with the telescopic rod of the push cylinder 3. The front end abuts against the grinding disc 5 on the output shaft of the motor 4, and then the motor 4 drives the grinding disc 5 thereon to rotate. Since the bearing ring 10 has relative movement between the two grinding discs 5, the end faces of both sides of the bearing ring 10 can be ground during the rotation of the motor 4. After the grinding is completed, the telescopic cylinder 6 drives the motor 4 to reset, and the pushing cylinder 3 continues to push the bearing ring 10 into the discharging channel 13 for discharging, and then the pushing cylinder 3 and the blocking cylinder 2 are reset in turn, and this cycle is repeated to realize the continuous grinding of the double end faces of the bearing, which greatly improves the production efficiency of the bearing.
