High-efficiency cutting grinding wheel

Abstract

The invention discloses a high-efficiency cutting grinding wheel comprising a base body and a grinding ring. Water outlets are hollowed on the grinding surface of the grinding ring and communicated with water flow passageways correspondingly arranged in the base body; the water flow passageways are converged at water inlets arranged on the base body; in the circular arc length range randomly set on the grinding surface, the number of the water outlets is more than 0 and less than 30, and the circular arc length set randomly is one to three times of a contact line between the grinding ring and a workpiece when the workpiece to be processed is ground; and the base body comprises two layers of substrates, the grinding ring is clamped and fixedly connected between the substrates, a water storage area playing the role of the water flow passageway is formed between the substrates, and the water inlets are ring ports arranged on the substrates. Enough water outlets are arranged so that the cuttings generated in a grinding processing area can be discharged rapidly, the surface roughness of a surface to be processed and the sharpness of the grinding wheel can be improved substantially, the grinding wheel can be ensured to be suitable for the rapid and high-speed process, and the production efficiency is improved.

Description

(1) Technical field: [0001] The invention relates to a grinding tool, in particular to a high-efficiency cutting grinding wheel. (two) background technology: [0002] The grinding of metal or non-metallic materials is done with grinding wheels. For plane processing, grinding wheels with a flat grinding surface (or a flat running track) are used, while for special-shaped edging processing, special-shaped grinding surfaces are often used. Grinding wheel. The grinding wheel will generate a lot of grinding heat and powder chips during the cutting process, so cooling is required during grinding wheel processing (surface grinding and special-shaped grinding). The cooling method provides cooling water for the cooling mechanism of the grinding wheel processing machine tool, and the cooling water acts on the grinding wheel. On the grinding surface, the cooling water cools the grinding surface on the one hand, and another important role is to wash away a large amount of powder chips....

AI Technical Summary

Problems solved by technology

When grinding, the working surface and the workpiece are closely combined, and the powder generated by grinding forms a seal for the cooling water. In fact, it is difficult for the cooling liquid to enter the working surface being processed, but it only plays the role of the grinding wheel. The role of pre-cooling before and cooling after the grinding wheel works; from the perspective of chip removal, the coolant can only wash away the chips outside the working surface, but it is difficult to do anything for the chips enclosed in the processing area

[0005] 2. The use of internal cooling grinding machine is to improve the cooling function of external cooling grinding machine. Internal cooling grinding machine should be equipped with grinding wheel with internal cooling structure. The structure of this internal cooling grinding wheel is the shaft at the center axis of grinding wheel base There is a water inlet aligned with the water outlet of the grinding wheel shaft of the internal cooling grinding machine on the hole, and there are a few water flow channels inside the grinding wheel base (normally divided into 120°, 90°, 60°, 45°, 30°, etc. Evenly distributed 3, 4, 6, 8, 12), and the grinding ring of the grinding wheel has a corresponding number of water outlets, the cooling liquid is supplied through the water outlet of the grinding wheel shaft where the grinding wheel is installed, and the cooling liquid enters the grinding wheel base from the water outlet of the grinding wheel shaft The water inlet of the shaft hole is sprayed from the water outlet on the grinding ring through the water flow channel and acts on the grinding work surface; from the perspective of chip removal, the amount of water sprayed from the water outlet is limited and the number of water nozzles is too small. Insufficient, it is also impossible to exclude the powder dust enclosed in the processing area

In the process of processing, the processing amount of various parts of the special-shaped grinding surface of the grinding wheel in the axial direction may be uneven, and some even have a relationship of magnification difference, but the material of the grinding wheel is uniform, which causes the special-shaped grinding of the grinding wheel. Each part of the surface wears differently depending on the amount of processing, which makes the special-shaped grinding surface of the grinding wheel very easy to lose shape and cannot be used normally. It needs to be repaired frequently or lost shape and scrapped
