Problems solved by technology
The current cooling method is mainly an external cooling method. Due to the low cooling efficiency of the airflow barrier of the grinding head, it not only increases the production cost, but also causes environmental pollution. Therefore, a low-temperature sintered internal cooling with controllable internal lubrication is designed. CBN grinding wheel is of great significance
[0005] The current cooling method in related technologies is mainly external cooling method. Due to factors such as the airflow barrier of the grinding head, the cooling efficiency is low, which not only increases the production cost, but also causes environmental pollution. No effective solution has been proposed yet.

Abstract
The invention discloses a lubricant-prefilled low-temperature glass powder binder sintered CBN grinding head, and relates to the technical field of dry type grinding machining. The lubricant-prefilled low-temperature glass powder binder sintered CBN grinding head comprises a grinding wheel mounting shaft, a grinding wheel end cover connected with the grinding wheel mounting shaft, a low-temperature sintering inner-cooling CBN outer circle grinding wheel connected with the grinding wheel mounting shaft and the grinding wheel end cover at the same time, and an inner cavity impeller arranged between the grinding wheel end cover and the low-temperature sintering inner-cooling CBN outer circle grinding wheel. The grinding wheel end cover, the inner cavity impeller and the low-temperature sintering inner-cooling CBN outer circle grinding wheel are sequentially and fixedly arranged on the grinding wheel mounting shaft through fasteners. The problems that the current cooling mode is mainly an external cooling mode, the cooling efficiency is low due to factors such as an airflow barrier of a polishing head, the production cost is increased, and environmental pollution is caused are solved.
Description
technical field [0001] The invention relates to the technical field of dry grinding, in particular to a CBN grinding head sintered with a pre-filled lubricant and low-temperature glass powder bond. Background technique [0002] Grinding is widely used in the machinery manufacturing industry, especially in the fields of automobiles and aerospace. With the wide application of new materials with high hardness, high strength, high wear resistance and high functionality, grinding technology is becoming more and more important. It is developing in the direction of high speed, high efficiency, low surface roughness, precision and intelligence. Therefore, finding efficient and high-quality grinding tools suitable for large structural parts is crucial to the surface quality of parts and the processing environment. [0003] At present, most of the surface grinding and polishing work of complex profiles at home and abroad are still in the manual grinding stage. Because it is diffic...
