Brass Frame Bushing Stone Crusher Machine Parts Small Tolerance Less Than 0.003m

It is mainly suitable for spring cone crusher, Simmons cone crusher, etc.The purpose bush of the frame Bush is installed in the main frame body to protect the frame. The use range of bushing is large and there are many kinds. In order to select a suitable bushing, it is necessary to consider its use purpose and select different types of bushing under different working conditions.
Production Feature :
1. High anti-wearing copper casting parts
2. Widely used in mining equipment, construction machine and metallurgy and other high loaded large machiner.
3. Strict casting processing control, make the tolerance less than 0.003m
4. Long working life and PRsmooth surface treatment






Product Specification;

Problems to be noticed in processing of copper bushing:

As we all know, copper sleeve has high hardness and good wear resistance, which is not easy to produce the phenomenon of seizing, and it also has good casting performance and machinability. It has very strong corrosion resistance. So it is also very careful in the process of manufacturing, so what should we pay attention to in the process of manufacturing?

1: When casting the copper sleeve, each process must be carefully handled. For example, the core must be placed in the right position when the box is closed, so as to avoid that the cast product cannot be processed according to the size due to this reason.

2: Before processing, first clean the casting, then get on the car, first calibrate, then get off the car when processing to the semi-finished product, and cool it, because copper has shrinkage, in order to process accurately, get on the car again when the workpiece is placed at room temperature for processing.

3: After the finished product, especially the straight sleeve cannot be placed horizontally, it shall be placed vertically to prevent deformation.

4: The packaging shall be reserved to avoid deformation due to accidental collision during transportation.

The product adopts the advanced production technology centrifugal casting. Compared with the sand mold, the copper sleeve produced can significantly improve the compactness and wear resistance of the casting, and has good tensile strength, flexure and elongation strength and tensile rate, not to mention the phenomenon of sand porosity like the sand mold casting. It is the first choice for many crusher mechanical products.
