Description

Combination electroplated grinding wheel

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to the technical field of grinding wheel tools, and more particularly to a combination electroplated grinding wheel.

First, in a facility without an internal cooling water supply structure, when an external cooling method is used, an airflow barrier is formed on the inner diameter, outer diameter and end face grinding surface due to the rotation of the grinding wheel, blocking the coolant entry into the grinding area, especially , the higher the rotation speed, the stronger the airflow barrier action, making it unsuitable for application to high-speed grinding technology. In addition, in the external cooling method, the coolant cannot act from the outer diameter to the inner diameter under the action of centrifugal force, so the part close to the inner diameter of the working section The cooling effect is extremely deteriorated. 1 shows the prior art.

1. As an improvement method, the base of the grinding wheel is hollowed out as much as possible, and the cooling water is introduced into the inner diameter cavity through the cavitation part as a water passage, so that the coolant acts from the inner diameter to the outer diameter along the direction of the outer diameter by centrifugal force. There is something to cool down. When cavitation of the base, the remaining “rib frame” that secures the connection strength collides with the coolant during high-speed rotation to form a turbulent layer or spray, which prevents the coolant from smoothly entering the inner diameter cavity, affecting the water flow. give.

2. Even if the coolant enters the inner diameter cavity, some coolant is lost through it, and the amount of coolant in the inner diameter and cross section of the grinding wheel is also small due to the action of centrifugal force.
