Description

Technical field

[0001] The invention relates to a clamping dual-purpose tool sleeve used for processing the inner cavity of a part sleeve of a steam turbine. Background technique

[0002] The shape and structure of the part sleeve of the steam turbine are complicated, and some processes require turning. However, due to the shape and structure of the workpiece, it cannot be processed on a lathe. The only option is to use a flat-rotating disk attachment on a boring and milling machine. The flat-rotating disk processing is better than a lathe Machining has its advantages. The lathe uses the workpiece to rotate and the tool performs linear movement to complete the machining. The cutting speed cannot be very large and there are limitations. In the case of boring and milling machines, the workpiece does not move. The tool moves linearly while rotating at high speed to complete the turning processing of the profile. The high-speed rotation of the tool for flat-rotation processing is hig...
