Gear Parts CNC heavy blasting machine
Aviation industry has a high demand for its parts, parts and materials not only requires light, and requires them to withstand extreme loads in extremely harsh environments. Parts of the surface by means of protection against external damage and fatigue life, our surface treatment can improve the overall performance of the part.
NC peening applications:
Fatigue- compressive stress by means of implants can effectively control a considerable degree of fatigue crack initiation and propagation;
Micro-wear-can lead to fatigue and wear damage to the micro suitable peening surface of the contact part can be improved and the compressive stress generated at the surface, thereby greatly reducing the possibility of the micro-wear;
Stress corrosion cracking- reducing surface tensile stress or make it down to the critical point will be able to eliminate the generation of stress corrosion cracking.
Peening process:
Shot peening technology is widely used to increase high-stress fatigue resistance metal parts, such as the aero-engine blades, aircraft structural parts. Any cyclic stress metal parts within its elastic range that exists can be eliminated by shot peening process.
Shot refined circular, glass balls or ceramic balls media, by air or centrifugal blast wheel blade method to these medium spray / thrown parts.
Peening process is introduced through the parts of the surface residual stress to achieve.
When one pill every material particles impinge on the part will produce a small dent, resulting in compressive stress. That show was pressed concave, then the material is concave under incurs compressed. And not only to produce a beat generating thousands of dimples on the surface of the dent.Final parts of the surface to form a compressive stress layer.
For life requires a very long-lasting and predictable key parts, such as aero engine parts and aircraft structural parts, strengthening the advantages of the process has been adequately proven.
The vast majority of parts used in the aviation industry, including aircraft skeleton, wings, engines, landing gear, drives, or transmission parts (gears), are used blasting / shot blasting technology to meet the performance indicators of the material.
