Description

Technical Field

[0001] The utility model belongs to the technical field of steam turbine cylinder bodies, and in particular relates to boring equipment for processing steam turbine cylinder bodies. Background Art

[0002] Steam turbine cylinder machining refers to the process of machining the cylinder of a steam turbine. A steam turbine is a device that converts thermal energy into mechanical energy. It usually includes one or more cylinders, each of which has a shaft and a series of blades. In a steam turbine, high-temperature and high-pressure gas generated by the burning fuel is sprayed into the cylinder through a nozzle, driving the blades on the shaft to rotate, thereby driving a generator or other mechanical device. Boring equipment is a mechanical device used to process holes in workpieces. Boring is a machining method that uses a rotating and feeding tool to machine holes inside a workpiece. This method is usually used to make large-diameter, high-precision, deep holes or holes of special shapes.

[0003] Boring equipment will produce fine iron filings and fine iron powder when boring, which are often difficult to clean, reducing production efficiency and having an adverse effect on equipment performance and accuracy.
