Superfinishingin the production and Application

Vibration Stress Relief in the market breakthrough in recent decades, vibration aging equipment processing research and application, in our country has achieved rapid development.During this period, with many domestic units together, in the mechanism of vibration aging equipment and applications, has achieved breakthrough results, made our country about vibration aging treatment technology of the national industry standards, to guide the application of the technology and equipment of the production progress, promoted the technology in machinery industry wide application.Vibration aging originated very early, in the last century fifty's, along with the development of modern science and technology, the vibration theory, the test technology and the excitation vibration aging equipment all gets rapid development.So that, in a workpiece resonance frequency of vibration, the vibration can shorten the processing time, eliminate stress and stability precision is better, also the least energy consumption.At the same time, there is a corresponding vibration equipment.This new type of vibration aging process and equipment appearance, immediately by the close attention of all countries, rapidly applied in production practice.As a result of this technology is mature with each passing day, vibration and control improving equipment, vibration aging has been for more than 10 industries are widely used in developed countries.Vibration aging usually only half an hour, electricity and a few yuan the cost limitation, can achieve the aging effect, but also can handle whenever and wherever possible, neither reduce the hardness, and no dust pollution and oxidation skin, it is the heat treatment and natural aging incomparable, known as desired without the costs of aging technology.Vibration aging equipment and processing technology and wide application of the technology have been found and develop.


Vibration Stress Relief in the production of the application of vibration aging equipment with his application approved by the majority of users, has gradually developed, the utilization of equipment, in production has played a great role in promoting, he can be used to stabilize the component deformation, improves the capacity of deformation resistance, improve component size precision at the same time, can effectively reduce and average residual stress, increase the working strength and fatigue life.Vibration aging equipment can also prevent the member in use in the crack.Vibration stress relief technology in relative machinery industry application is very extensive, no matter whether the object has multiple, can be used for handling vibration aging equipment.As long as the basis of structure type selection component vibration parameters and device, can achieve the purpose of eliminating the residual stress.But, even so, obviously, the equipment is still has its limitations.This is due to vibration ageing device performance limitations of the results.At present domestic and foreign production of vibration ageing device, its frequency range below 200Hz, long, wide, if component high ratio close to 1, and the stiffness of the structure is large, it may cause the component natural frequencies over Vibration Stress Relief use frequency range and no resonance.In this case, it must be used in low frequency and large exciting force technology or modular clamping method to reduce the frequency of.To make a long story short, vibration aging equipment and other large parts processing also has been widely applied, because he is a simple, efficient, energy saving, environmental protection and efficient advanced technology, without the size, weight, structure and space limitations, it is worth of application and promotion.
