Solidified metal bonding agent grinding wheel with inner flow passage structures, device and preparation technique

Abstract

The invention discloses a solidified metal bonding agent grinding wheel with inner flow passage structures, a device and a preparation technique. The solidified metal bonding agent grinding wheel withthe inner flow passage structures comprises a grinding wheel base body and a grinding wheel grinding main body. The grinding wheel grinding main body is arranged on the outer side of the grinding wheel base body and provided with the inner flow passage structures. According to the solidified metal bonding agent grinding wheel with the inner flow passage structures, the inner flow passage structures are arranged on the grinding wheel grinding main body, accordingly, the cooling capacity of the grinding wheel can be improved, the heat exchange efficiency is improved, and a grinding workpiece isprevented from being burned.

Description

technical field [0001] The invention relates to the technical fields of grinding and additive manufacturing, in particular to a consolidated metal bond grinding wheel with an inner flow channel structure, a device for manufacturing a consolidated metal bond grinding wheel with an inner flow channel structure, and a device with an internal flow channel structure. The preparation process of the consolidated metal bonded grinding wheel with track structure. Background technique [0002] In related technologies, the traditional manufacturing process of consolidated metal bond grinding wheel is mainly hot pressing forming method. In the hot pressing method, firstly, the metal bonded abrasive grains and the bonding agent are mixed evenly in a certain proportion, and a certain pressure and temperature are applied on the basis of natural accumulation of the mixture, and finally formed. [0003] However, the pores of the metal bond grinding wheel manufactured by the traditional hot ...

AI Technical Summary

Problems solved by technology

[0003] However, the pores of the metal bond grinding wheel manufactured by the traditional hot pressing process are blocked, and no effective flow channel structure is formed between the pores. This blocked pores affects the grinding fluid entering the grinding arc during the grinding wheel grinding process , reducing the heat transfer efficiency

However, the grinding wheel generates a lot of heat during the grinding process. A grinding wheel without a runner structure will cause more than 90% of the heat to be transmitted to the workpiece, which can easily cause burns on the grinding workpiece.
