Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, in particular to a tool for simultaneously chamfering inner and outer circles. Background Art

[0002] External hole processing tools are widely used in the field of CNC. They are used to chamfer the external and internal holes of workpieces. The traditional processing method is to chamfer the hole with a chamfering tool. It takes at least two cycles to complete all the processes of chamfering and deburring the external circle. Some companies even use manual deburring, which is not only inefficient and tiring for workers, but also requires at least two cycles to complete all the processes. For batch parts, the traditional method is particularly inefficient, and sometimes even requires a tool change to complete.

[0003] In addition, with the increasingly fierce competition in the field of CNC machining, it is also crucial to control the processing cost. CNC tools are the largest consumables in the field of CNC machining. Customers also attach great importance to the service life and price of tools. How to purchase tools with better processing performance at a lower cost is what customers are eager to get. If the process processed by two or three tools can be completed by only one tool, and the processing is simple, the required technical support is also greatly reduced, which not only reduces the cost of tools, but also improves production efficiency. It is a very cost-effective tool for customers and greatly meets the needs of customers. Therefore, internal and external chamfering tools play a great role in batch deburring and reducing the labor burden. Summary of the invention
