[0040] When in use, the workpiece slots are designed to be 8, 16, or 32 pieces / group, and the workpiece spacing is an equal fraction of the machine tool spindle spacing. For example, if the machine tool spindle spacing is 140mm, the workpiece spacing can be designed to be 17.5mm, 35mm, or 70mm according to the workpiece diameter. Then the number of workpieces that can be installed on the entire rack is 32, 16, or 8 pieces, respectively.

[0041] When in use, workers install 16 workpieces onto the auxiliary support at a time; at this time, workpieces 1, 5, 9, and 13 are in the processing position, and the machine tool automatically clamps workpieces 1, 5, 9, and 13;

[0042] The machine tool automatically performs deep hole processing;

[0046] The machine tool automatically performs deep hole processing;

[0047] After the second group of processing is completed, the CNC servo moves the guide rail to move one axis spacing, that is, 35mm; ......

[0048] Until all workpieces are processed.

[0049] At this time, the auxiliary support of the workpiece is moved outside the machine tool, and all the workpieces are replaced manually.

[0050] Therefore, the number of workpieces installed at one time has increased by 2, 4, or 8 times, the frequency of workers loading and unloading workpieces has been greatly reduced, and the labor intensity of workers has also been reduced.

[0051] After the machine tool has processed a group of parts, the feeding mechanism moves horizontally by a workpiece spacing to complete the replacement of the blank workpiece and the finished workpiece. The downtime is very short and the processing efficiency of the machine tool has been greatly improved.
