CNC machining track parts solution
Aug 02, 2018

In actual work, CNC machining track parts usually have certain processing difficulties, especially the locomotive running parts such as body bogies, hollow bushings and key parts of diesel engines. For example, the main components of the locomotive diesel engine have complex structure, high manufacturing precision, geometrical position tolerance and surface quality requirements, and require good interchangeability.

 

The reason why the processing quality requirements of CNC machining track parts is so strict is to ensure the reliability of the locomotive in high-speed operation, long life and high safety factor. In general, the main difficulty is that the blank extrusion requirements are high, and the non-machined surface size requirements after molding are high; the balance block welding requirements are also not used in the original middle crankshaft; due to the balance block welding structure, the radius of gyration of the machined equipment Increased, high dimensional tolerance requirements.

 

In addition, in the process of CNC machining of track parts, it is also difficult to control the deformation of the workpiece. Under normal circumstances, the machining of CNC machining track parts is mainly composed of basic processing methods such as turning, milling, planing, boring, drilling and grinding.
