AI Technical Summary
Technical Problem
Existing technology requires two tools to perform multiple roughing and finishing operations when machining irregular outer circular shapes, resulting in low machining efficiency, long tool change time, large tool magazine space occupation, and unstable machining accuracy.
Method used
Design a double-ended cutting tool with a single tool body and two detachable cutting heads. The tool can switch freely between inner and outer circles by adjusting the direction of the cutting heads, and can be used for roughing and finishing machining respectively.
Benefits of technology
It improves processing efficiency, reduces tool change time, saves tool magazine space, avoids degradation due to secondary processing, ensures processing accuracy, and reduces manufacturing costs.

Abstract
A double-head cutter for machining an inner circle and an outer circle comprises a cutter body, a first cutter head and a second cutter head, a first blade clamping groove and a second blade clamping groove are formed in the two sides of the tail end of the cutter body respectively, the first cutter head is detachably connected to the first blade clamping groove, the second cutter head is detachably connected to the second blade clamping groove, and the installation direction of the first cutter head and the installation direction of the second cutter head are adjustable. According to the utility model, through the structure of one cutter body and two replaceable cutter heads, the original processing mode of respectively finish turning and rough turning by two cutters is changed into the mode of simultaneously rough turning and finish turning by one cutter, and random switching of inner circle processing and outer circle processing is also realized. The machining efficiency is improved, one tool magazine is saved, meanwhile, secondary machining deterioration caused by tool changing is avoided, and the machining precision is improved.
