When copper bushing to plan, in addition to according to the working conditions and the metal material properties determine the geometric shape and size of machine tool castings, must also think in terms of casting alloy and the characteristics of the casting process planning of rationality, the obvious scale effect and solidification, stress and shorten the problem, in order to prevent or reduce the occurrence of defects, such as component segregation, deformation and cracking of large copper casting. So what factors will affect the quality of copper base bushing? Next, by the small edition of Hangzhou copper base bushing to explain it, I hope to be helpful to you.

First, reasonable casting process. In short, according to the structure, weight and size of the casting, the characteristics of the casting alloy and the production conditions, the appropriate parting surface and shape, the production method of the core, and the reasonable setting of the casting bar, cold iron, riser and gating system. To ensure high quality castings. If you do not improve the quality of large copper casting machine tools, it is impossible to talk about the development of machine tool equipment production and the overall level of improvement, will affect the competitiveness of China’s machine tool equipment manufacturing industry. Industry in the world market. Continuously improve the quality of copper castings for large machine tools to ensure the overall improvement of the production level of machine tools.

Two, the impact of copper casting quality on the performance of mechanical products: in terms of the wear resistance and dimensional stability of the copper casting machine tool, will directly affect the accuracy and durability of the machine tool; All kinds of pump impeller, chassis and hydraulic parts size, profile accuracy and surface roughness directly affect the pump and hydraulic system efficiency, energy consumption and the development of cavitation; The strength and resistance of the cylinder block, cylinder head, cylinder liner, piston ring, exhaust pipe, etc., as well as cooling and heating directly affect the service life of the engine.

The above two points are all about the two factors that affect the quality of copper-base bushing. Thank you for your understanding and support!
