Description

Technical Field

[0001] This utility model relates to the technical field of truck wheel hub processing, specifically an improved integrated drilling and milling tool for truck wheel hub processing. Background Technology

[0002] Currently, the common processing technology for bolt holes and chamfers on both sides of truck wheel hubs is as follows: the bolt holes are machined with a bolt hole drill bit, and then the chamfers on both sides are machined with a chamfering milling cutter. This process produces products with stable quality, but the production efficiency of processing with two tools is low, the process is cumbersome, and there is a risk of dimensional defects caused by deviations in the fit between the tools. Therefore, integrated drilling and milling tools have appeared on the market.

[0003] However, in existing integrated drilling and milling tools, the milling structure and the tool holder are fixed. In actual use, the milling structure is prone to breakage due to frequent wear. Tools with broken milling structures can no longer be used and are discarded, while the other parts of the tool remain intact. Over time, this leads to a waste of resources and low tool stability.
