The entered parameters include the size specification information of the large pipe seat, the grinding length of the large pipe seat and the number of grinding times, which can be selected and entered according to the grinding situation. After the parameters of the large pipe seat are entered, the intelligent numerical control system will automatically generate the grinding movement path of the belt grinder 31.

The beating shaft 341 continuously beats the grinding belt 312 when it rotates. When dust such as metal powder is adhered to the grinding belt 312, the beating shaft 341 can beat the dust on the grinding belt 312 in time, and the main shaft 12 drives the chuck 11 and the large pipe seat clamped on the chuck 11 to rotate at a uniform speed, and the intelligent CNC system control 32 drives the belt grinder 31 to automatically grind the large pipe seat according to the planned path, and the grinding belt 312 contacts the outer circle of the large pipe seat to realize the grinding of the large pipe seat.

[0044] When the belt sander 31 is started, the intelligent numerical control system also controls the dust collector 83 to start. After the dust collector 83 is started, the dust generated by the belt sander 31 is collected through the first connecting pipe 81 and the second connecting pipe 82 .

[0045] After the processing is completed, the two-axis feeding mechanism 32 drives the belt grinder 31 to run to the initial position, the belt grinder 31 stops rotating, the spindle 12 stops rotating, and the waste chip cleaning and collecting mechanism 8 stops operating.

[0046] After grinding is completed, the large pipe seat is unloaded, the sliding door 22 is controlled to open automatically, and then the chuck 11 is controlled to open, and the polished large pipe seat is taken away. The automatic opening and closing of the sliding door 22 can be completed by equipping an industrial robot.
