Design and Manufacture of Spindle Bores for Processing Large Diesel Engine Bodies

The machining of the main shaft holes of large diesel engine bodies generally faces problems such as long boring tool lengths and poor stability when working with spindle-driven boring tools. In order to improve the efficiency of the main bore processing while ensuring the precision of the processing, the research has designed a spindle bore installation suitable for processing large diesel engine bodies. By positioning the support components, the body is positioned precisely and steadily, and the guide setting reduces the need for boring tool length, allows the roughing of the main shaft hole and the processing of the thrust surface to be completed in one go, reduces the processing cycle of the main shaft hole, and increases the productivity of the enterprise.
