2) since the rotation of grinding wheel main body generates centrifugal force, coolant liquid guiding tube is elastic hose, and coolant liquid guiding tube exists
Deformation occurs under the action of centrifugal force, and the deformation of coolant liquid guiding tube changes the flow velocity size of coolant liquid；Specifically: grinding wheel main body
Revolving speed is faster, and the centrifugal force of generation is bigger, and the deformation amplitude of coolant liquid guiding tube is bigger, the stream of coolant liquid in coolant liquid guiding tube
Speed is also bigger, and more coolant liquids are injected in grinding surface；Conversely, grinding wheel main body revolving speed is slower, the centrifugal force of generation is smaller, cold
But the deformation amplitude of liquid guiding tube is smaller, and the flow velocity of coolant liquid is also smaller in coolant liquid guiding tube, and less coolant liquid is injected in
In grinding surface；
Preferably, this method further includes step 3), the deformation of coolant liquid guiding tube is controlled by deformation limiting device；Tool
Body are as follows: adjusting rod is promoted, drives stop collar mobile toward the top of grinding wheel main body, expands the moving area of coolant liquid guiding tube,
Until coolant liquid guiding tube is kept completely separate with stop collar, the deformation of coolant liquid guiding tube is realized certainly by the revolving speed of grinding wheel main body completely
It adapts to adjust；Conversely, reducing adjusting rod, top of the stop collar far from grinding wheel main body is driven, contracting mobile toward the bottom of grinding wheel main body
The small moving area of coolant liquid guiding tube, in grinding wheel body rotation, stop collar limits the deformation of coolant liquid guiding tube, cooling
The deformation of liquid guiding tube is by the revolving speed of grinding wheel main body and the position control of stop collar.
In this application, by the way that independent coolant liquid guiding tube is arranged, coolant liquid is introduced from the top of grinding wheel main body, and will
Coolant liquid is guided to grinding wheel lower body outer, and coolant liquid carries out cooling to grinding area, lubricates while grinding part is ground
With wash away.It is independently arranged coolant liquid guiding tube in the inner cavity of grinding wheel main body, technical threshold is low, simple production process.So that interior cold
Formula grinding wheel is more easily manufactured, and production cost is low.
In this application, grinding wheel main body is downwardly open, is grinding wheel geometric central axis line area at the center of grinding wheel body top
