Nano ceramic bond diamond wheel containing tetrapod-like zinc oxide whiskers reinforced and preparing method of nano ceramic bond diamond wheel
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.
