Internal cooling type grinding wheel for external cooling type grinding machine

Abstract

The invention discloses an internal cooling type grinding wheel for an external cooling type grinding machine. The internal cooling type grinding wheel comprises a basal body and a grinding ring, wherein water outlets are formed on the grinding surface of the grinding ring in a hallowing manner, all the water outlets are communicated with water flow channels which are correspondingly arranged in the basal body, all the water flow channels are converged at a water inlet formed on the basal body, the water inlet on the basal body is of an open port communicated with a cooling pipe of the external cooling type grinding machine, the basal body comprises a baseplate and a pressure plate pressed on the baseplate, the grinding ring is clamped and fixed between the baseplate and the pressure plate, a hollow water storage area for playing a role as the water flow channel is further formed between the baseplate and the pressure plate, and the water inlet is formed on the pressure plate. The internal cooling type grinding wheel disclosed by the invention has an internal cooling structure, and can enable most of external cooling type machining equipment on the market to achieve the performances of internal cooling type machining equipment without increasing any cost nearly and avoid investing more money for purchasing the expensive internal cooling type machining equipment, so that economic benefits are very obvious.

Description

(1) Technical field: [0001] The invention relates to a grinding tool, in particular to an internal cooling grinding wheel for an external cooling grinding machine. (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. Due to the grinding heat generated during grinding, especially high-speed grinding, cooling is required during grinding wheel processing (surface grinding and special-shaped grinding). The cooling method is provided by the cooling mechanism of the grinding wheel processing machine tool. According to different cooling methods, the current Grinding wheel processing machine tools are divided into external cooling grinding machines and internal cooling grinding machines. [0003] 1. The cooling...

Problems solved by technology

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
