Problems solved by technology

There are many disadvantages in this way: two equipment and two tools are required to process a part, which greatly increases the processing cost and cycle time, and seriously wastes resources; the drilling and deburring processes are separated, and the parts are clamped twice. Affect the precision of processing

Abstract

The invention aims to provide a drilling and chamfering composite quick forming tool. The drilling and chamfering composite quick forming tool has the advantages that the drilling and inner hole deburring integrated tool is formed according to merits of a short-hole drill and merits of a spring tool, two traditional machining tools are integrated into the single drilling and chamfering composite quick forming tool, and accordingly the cost of the drilling and chamfering composite quick forming tool can be greatly reduced; drilling and inner hole deburring can be completed on the same equipment and machine, so that the cost of the equipment can be saved; an operation worker can complete machining parts, so that the labor cost can be reduced; the machining period can be greatly shortened, and the drilling and chamfering composite quick forming tool is high in efficiency; each part can be machined after being clamped at one step and can be completely machined at one step, accordingly, repeated positioning can be omitted, and the machining precision can be improved.

Description

1. Technical field [0001] The invention relates to a combination tool, in particular to a drill-inverting compound rapid prototyping tool. 2. Background technology [0002] The CNC milling machine uses a shallow hole drill to drill the part, and the inner surface of the hole will produce burrs. It seriously affects the quality of the parts and is extremely beautiful. It needs to be deburred in the post-processing process, which is time-consuming, wastes resources and increases costs. [0003] The invention particularly relates to the drilling of pipes and the deburring of the inner holes: after the holes are drilled with a shallow hole drill, the burrs on the inner surfaces of the holes are difficult to remove with traditional cutters. A special spring tool is used for deburring the bore. There are many disadvantages in this way: two equipment and two tools are required to process a part, which greatly increases the processing cost and cycle time, and seriously wastes reso...
