[0001] The utility model relates to the technical field of breaker hammer cylinder body processing, in particular to a breaker hammer cylinder body through-hole cutting tool. Background Art

[0002] A breaker hammer, also known as a hydraulic breaker or hydraulic stone breaker, is an important working tool of a hydraulic excavator. The cylinder of the breaker hammer is one of its core components. It carries the reciprocating motion of the piston and is connected to the hydraulic system through the through-hole on the cylinder. The design of the cylinder through-hole directly affects the working efficiency, stability and service life of the breaker hammer. Therefore, there are extremely high requirements for the cutting accuracy and surface quality of the cylinder through-hole. When processing the through-hole of the breaker hammer cylinder by traditional methods, problems such as drilling difficulty, low accuracy and slow speed are often encountered. By optimizing the tool structure and cutting parameters, the vibration and wear in the cutting process can be reduced, thereby reducing the processing cost. At the same time, high-precision processing also reduces the workload of subsequent processing and correction.
