[0002] Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The existing grinding device cannot collect the iron chips generated by grinding when processing the valve stem.

[0003] In the prior art, a Chinese patent document with publication number CN214519376U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a grinding device for a CNC lathe for valve stem processing, which belongs to the field of mechanical processing technology, and comprises a workbench, a grinding device is arranged on the upper side of the workbench, movable blocks are arranged on both sides of the upper end of the workbench, a clamping device is arranged on the upper end of the movable block, a through groove is arranged at the middle position inside the workbench, a filter screen is arranged on the upper side of the through groove, and a collection box is arranged on the lower side of the filter screen. The utility model generates iron filings when the grinding device grinds the valve stem by arranging the collection box.

[0004] In order to solve the problem that the existing grinding device is unable to collect the iron chips generated by grinding when processing the valve stem, the existing technology adopts a method of uniformly collecting the iron chips generated by grinding by setting up a collection box. However, the chips generated by grinding will still float around, resulting in some chips being unable to fall into the collection box, and the scattered chips will stick to the equipment and affect its use. Utility Model Content

At the same time, the efficiency of chip removal is also improved to prevent incomplete collection by the collection box alone.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
