Definition of VSR(vibratory stress relief)
It describes a physical process is this: that is tightly controlled using a vibration energy,
the metal work piece is processed to resolve the workpiece during and after the processing of
the internal and residual stresses occur dimensional changes resulting load capacity and resistance to change.VSR（vibratory stress relief) to eliminate, reduce or homogenizing the residual stress of the metal workpiece, the workpiece to improve resistance to static and dynamic load, the deformation resistance, stability, efficacy superior dimensional accuracy.

VSR(vibratory stress relief) principle
From the micro level analysis, VSR can be regarded as a kind of cyclic loading is applied in the form of an additional stress on parts. When the workpiece is subjected to vibration applied to the alternating stress on parts and components in the residual stress superposition. When the result of superposition of the stressreaches a certain value, the worst part of the stress concentration will exceed the yield limit of the materialis plastically deformed. This is where the residual plastic deformation reduces the stress peaks and strengthen the metal matrix, and then the vibration but also in other parts of the stress concentration is generated on themore serious the same effect until the vibration superposition of additional stress and residual stress of thealgebraic and not cause any part of the plastic deformation, at which time, and both vibration to eliminate residual stress and strengthening of metal on the end of the process.

Superfinishing Equipment

The brief:

1. Obtain surface roughness less than Ra0.1 easily;

2. Suitable for different shapes, such as cylindrical, internal, rotor, curved and spherical, axis,etc;

3. Suitable for all kinds of materials, such as carbon steel, aluminum alloy, copper, etc;

4.Suitable for different industries, such as Turbine, Mining machinery, Mechanical valve, Petroleum Machinery, Bearing mechanical, Mold, Paper machinery, Pharmaceutical Machinery centrifuge, Piston rod, Hydraulic cylinder, Helical rod, Metallurgical Machinery, Wind power, Hydropower, Motor.

5.Can be used in all kinds of machine tools, such as lathe, grinding machine, boring machine, milling machine, planning machine, spherical lathe and CNC machine tools, ect;

6. Just one time, improve production efficiency greatly;

7. Components: tool assembly and control-center;

8. Improve the micro-hardness 20%;

9. Improve the wear-resistance;

10. Improve the fatigue life 5 ~100 times;

11. Suitable for the hardness below HRC65;

12. Improve corrosion resistance;

13. It’s a nonabrasive process, without abrasive, felt, lapping compounds and hard work. 

14.Relieve the residual stress greatly;

15.Long service life of tool and workpieces;

16. It saves time, money and energy;

17. No sawdust and sawdust wastes occurred,no noise and damage to the environment;

18.Easy to operate.

The principle:

According to metallic materials cold plastic deformation in the normal temperature and apply HB-superfinish equipment to superfinish the surface without any abrasive to reach desirable roughness,this process just like ironing clothes.

The process:

Firstly, make the workpiece pre-machining in the general purpose machine, then apply HB-super finishing equipment again, the roughness will reach less than Ra0.1 easily, just like ironing the clothes and a kind of compressive stress created on the surface at the same time, the micro-hardness will be improved more than 20%, the wear resistance will be improved greatly and the life will be improved 5 ~10 times.

The description:

This equipment including two parts, one is cutter, the other is control center,

the cutter is controlled by control center,

there is a unstable ball which made from a special materials on the cutter head,

during process, the ball impacts the surface 30,000 times per second with very little pressure about 2.5N,

the temperature is little higher than the normal temperature,

it's a nonabrassive process, without abrasive, felt, lapping compounds and hardwork,

save time and cost greatly, and very environmental,

it's very different from the rolling, polishing, grinding and other process,

more precisely, it just like ironing the clothes, never remove any materials from the surface.
