Abstract

The invention discloses a nano ceramic bond diamond wheel containing tetrapod-like zinc oxide whiskers reinforced. In the diamond wheel preparing process, nano-graphite powder, beta- eucryptite and other raw materials are utilized firstly to be mixed with nano-order silicon dioxide, nano-order aluminium oxide and other raw materials for roasting, and a nano-order composite nano ceramic bond is prepared. Compared with a conventional ceramic bond, the nano ceramic bond has higher strength and tenacity and lower roasting temperature, the high-temperature wettability is better, the thermal expansion coefficient is low, and the control performance over abrasive materials is good. In addition, the tetrapod-like zinc oxide whiskers added in the raw materials have the obvious effects of tenacity reinforcing, noise lowering, vibration resisting, machining performance improving and the like. The prepared diamond wheel is low in roasting temperature, high in density, good in grinding performance and high in workpiece grinding precision, and the grinding speed can be obviously increased.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic bonded diamond grinding wheels, in particular to a nano ceramic bonded diamond grinding wheel reinforced with tetraacicular zinc oxide whiskers and a preparation method thereof. Background technique [0002] Diamond abrasives have the characteristics of high hardness, high strength, and good wear resistance. They are widely used in the production of abrasive tools for grinding hard and brittle materials and cemented carbide. Diamond grinding wheels are one of the common types of abrasive tools. According to the requirements of diamond grinding wheels The classification of the bond used can be divided into resin bond diamond grinding wheel, metal bond diamond grinding wheel and vitrified bond diamond grinding wheel, etc. The vitrified bond grinding wheel is made of vitrified bond, diamond abrasive and filler according to a certain ratio. , after high temperature sintering, this kind ...
