Description
Technical Field
The invention relates to the technical field of grinding wheel tools, in particular to an external-rotation internal-cooling interchangeable electroplated cup type grinding wheel.
Background
Firstly, for equipment without an internal cooling water supply structure, if an external cooling mode is adopted, an airflow barrier is formed on the grinding surfaces of the inner diameter, the outer diameter and the end surface due to the rotation of the grinding wheel, cooling water is prevented from entering a grinding area, and particularly, the higher the rotating speed is, the stronger the airflow barrier effect is, so that the equipment is not suitable for the technical application of high-speed grinding. In addition, in the external cooling system, since the cooling water cannot act in the inner diameter direction from the outer diameter by the centrifugal force, the cooling effect on the portion of the working end surface close to the inner diameter is extremely poor. The prior art is shown in fig. 1:
1. the improvement mode is that the grinding wheel is hollowed out on the base body as far as possible, cooling water is injected into the inner diameter cavity through the hollowed-out part as a water passage, and the cooling water cools the ground surface from the inner diameter to the outer diameter along the radial direction under the action of centrifugal force.

However, the renovation is carried out on the original substrate, the working procedures are complex, the working procedures of deplating the diamond, trimming the substrate to meet the precision requirement, plating the diamond again and the like are needed, the electroplating link is particularly complicated, and the productivity is low and the cost is high.
Secondly, the electroplated diamond grinding wheel is provided with grinding materials in a single layer, the exposed height of diamond is smaller than half of the particle size, the space in a grinding area (the contact area of the grinding wheel and a workpiece) is narrow, the space is occupied and blocked by powder, cooling water under the action of centrifugal force flows from the inner diameter to the outer diameter along the radial direction, the amount of the cooling water which flows through the cooling water is very small, and the thinner diamond is difficult to flow through, so that the cooling effect is greatly limited, and the grinding efficiency is further influenced.
And thirdly, the electroplated diamond grinding wheel usually adopts micro-powder diamond, so that the grinding wheel can normally work, the requirement on the machining precision of the base body is high, high-precision machining equipment is required for machining, if the precision cannot be met, the diamond layer is easy to perforate, delaminate, burn and damage, the base body is possibly damaged, and the renovation frequency of the base body is reduced or even the base body cannot be reused.
