The reasons such as difference, coolant absorption and the vibration that generates is referred to as imbalance, wheel unbalance directly affects the surface quality of workpiece.
For high-speed grinding, wheel unbalance has not only broken up the machining accuracy of workpiece, goes back the precision of entail dangers to axis system, very
Machine tool structure can extremely be damaged.
Wheel balance is the know-how of grinding.In the industrial production of early stage, grinding accuracy and efficiency will
It asks all than relatively low, as long as grinding wheel is made to reach static balance, just attaches it on grinding wheel spindle.As Grinding Technology is horizontal not
Disconnected to improve, static balancing method has been difficult to meet the requirements, and people begin one's study grinding wheel on-line dynamic balancing.A kind of method of simplicity
It is:Dynamic detection is carried out to installed grinding wheel with dynamic balance instrument, the position of wheel balance block is adjusted according to the result of detection,
Until reaching equilibrium state.Due to the continuous improvement of the accuracy of detection and operative skill of dynamic balance instrument, this method can obtain
Very high balance quality.However, its drawback is also obvious.First, counterbalance effect is largely dependent upon operation
The operative skill of person.Second, the equilibrium state of grinding wheel can not be monitored, adjusted in real time.The equilibrium state of grinding wheel is dynamic, is being ground
During cutting, since grinding wheel is lost, the Mass Distribution of grinding wheel itself constantly changes, and the equilibrium state of grinding wheel is caused constantly to send out
Changing.In the not high occasion of required precision and grinding speed, this variation can be ignored, but in high-precision, high-speed grinding
In the case of, it is this ignore be likely to result in serious consequence.Develop in process equipment to precise treatment, NC postprocessing, information-based direction
Today, there is an urgent need to a kind of grinding wheel on line auto balancing devices, and the equilibrium state of grinding process medium plain emery wheel is monitored in real time
And adjustment.
