Preparations to be done before ball guide pin processing
The ball guide post is also called the rolling guide post, which can be used in the assembly process. It mainly uses a steel ball rolling principle to prevent the steel post from falling off. Usually it has a cylindrical shape with a corresponding oil groove. Only the correct processing can meet the corresponding needs. Before the ball guide pin is processed, some preparations need to be made to ensure the smooth progress of the entire process. 
Preparations for ball guide pin processing: 1. The Mold Parts factory introduces the selection of blank material and its heat treatment. The fast-moving wire-cutting machine tool uses emulsion to cut common materials such as copper, aluminum, and quenched steel. The processing process is generally stable and the cutting speed is also fast. When cutting difficult-to-cut materials such as stainless steel, magnetic steel, and cemented carbide, the machining process is not stable and the cutting speed is slower. 2. The working parts of the ball guide pin generally use forging blanks, and the wire cutting process is often performed after the heat treatment such as quenching and tempering. When the metal is removed in a large area and the parts are cut off, it is often due to the internal material The relatively balanced residual stress distribution state is unbalanced and damaged, which leads to deformation of the parts and damage to the machining accuracy. In severe cases, the material may suddenly crack during the cutting process. Therefore, the complex-shaped cavity ball guide column is before the wire cutting process The stress relief heat treatment is very important. While ensuring the dimensional accuracy of the matching part of the guide post and the mold, the mold parts factory must also ensure the coaxiality of the surface. It is the coaxiality between the upper and lower mating surfaces of the guide column and the coaxiality between the inner and outer surfaces of the Guide Sleeve. When the guide post is processed, it is made of bar stock, the center hole is repaired after heat treatment, and then it is ground on a cylindrical grinder.
