PMI (polymethacrylimide) foam carving dust removal cutter

Abstract

The utility model discloses a PMI foam carving dust removal cutter, and belongs to the technical field of PMI foam machining equipment. By arranging the cutter handle body with the chip inlet hole and the chip outlet hole, in the machining process, the negative pressure pipe is connected to the air outlet mechanism of the rotating assembly to generate negative pressure, so that foam powder chips generated in the chip cutting process can be sucked in from the chip inlet hole, sent out of the cutter handle body through the chip removal hole and finally discharged through the connected negative pressure pipe; therefore, foam chippings are removed in the machining process, the situation that the chippings splash everywhere to affect the machining environment is avoided, and meanwhile the situation that the chippings are attached to workpieces to affect machining and reduce efficiency is avoided.

Technical Field

[0001] The utility model belongs to the technical field of PMI foam processing equipment, in particular to a PMI foam carving and dust removal tool. Background Art

[0002] Milling is a very common method in mechanical processing operations. Traditional milling tools are usually used to process metal materials. The debris generated during the cutting process is heavy and will fall on the surface of the equipment. However, since the powder generated by PMI foam after cutting is light, it is easy to splash around during the cutting process. Moreover, due to its small particles, it is easy to adhere to the surface of the workpiece during the processing, thus affecting the cutting accuracy.

[0003] Therefore, it is necessary to design a dust removal tool with a simple structure, which can greatly increase the workpiece processing progress and improve the cutting efficiency. Summary of the Invention
