Description

Combination electroplated grinding wheel

The present invention relates to the field of grinding wheel tool technology, and specifically to combination electroplated grinding wheels.

First, in equipment 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 cross-section grinding surface due to the rotation of the grinding wheel, blocking the entry of coolant into the grinding area, especially , the faster the rotation speed, the stronger the airflow barrier effect, making it unsuitable for application in high-speed grinding technology. Additionally, in the external cooling method, the coolant cannot act from the outer diameter toward the inner diameter under the action of centrifugal force, so the part close to the inner diameter of the operating cross section The cooling effect becomes extremely worse. Figure 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 coolant is introduced into the inner diameter cavity using the cavitation area as a water passage, so that the coolant flows from the inner diameter to the outer diameter along the direction of the outer diameter by centrifugal force. There is something that cools it down. When the base is hollowed out, the “rib frame” of the remaining part that secures the connection strength collides with the coolant during high-speed rotation, forming a turbulent layer or spray, preventing the coolant from smoothly entering the inner cavity, affecting the water volume. give.

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

3. Grinding wheel bases are difficult to process and expensive, so refurbishing is a frequently used method to reduce costs. However, refurbishing the original base requires processes such as removing the diamond plating, trimming the base to meet precision requirements, and diamond re-plating, making the process complicated. In particular, the electroplating procedure is complicated, and production capacity is low. Cost is high.

Second, the electroplated diamond grinding wheel installs the abrasive in a single layer, and because the exposed height of the diamond is less than half the particle diameter, the space in the grinding area (the area in contact with the workpiece of the grinding wheel) is narrow, and the space is confined to the grinding chips. It is charged and blocked, and the amount of coolant flowing from the inner diameter to the outer diameter along the radial direction due to centrifugal force is very small, and the finer diamonds are, the more difficult it is to flow, greatly limiting the cooling effect and further affecting grinding efficiency. .

Third, electroplated diamond grinding wheels often use micropowder grade diamond. In order to operate the grinding wheel normally, the machining precision of the base is high, and it must be processed with high-precision machining equipment, and precision is required. If this is not met, the diamond layer may easily be perforated or delaminated, the workpiece may be burned out, and the base may be damaged, reducing the number of base refurbishments or even making repeated use impossible.
