Ceramic cutting tool knowledge alumina (corundum) used in the abrasives and grinding tools, has a long history of international quantity used annually is great, the alumina raw material of tungsten carbide and nitride raw material is the most inexpensive, The tool alumina prices. The proportion of alumina is about tool Carbide (WC group) third ceramic knives, volume prices, cheaper than aluminum carbide cutting tool, which is to promote the development of international factors alumina tool one. The aluminum oxide (alumina) ceramic tool is its development of fine tip products, is a model of modern alumina ceramic, ceramic knife processing, its high added value. Al2O3 (alumina) powder 4 to 5 yuan / kg, while the price of alumina-based tool from 2000 to 3000 yuan / kg. 2007 sales in Western countries ceramic cutting tools is estimated at more than 45 billion US dollars, accounting for about half of the alumina-based ceramic tool. Among them, Japan's largest output, ceramic knife price, followed by the United States, Germany, Britain, and Russia also has a certain scale production. However, this material widely domestic resources, low cost, capable of producing high value-added tools but development is not, Huanggang ceramic knife, possibly rich Chinese tungsten resources and emphasis on tungsten carbide cutting tools related. 1. The overall judgment as sharp cutting ceramic knife. Knife cutting A4 paper, high quality ceramic knife cutting sense in the cutting process is very smooth, easy, and low-quality ceramic knife during the cutting process, there are a sense block. 2. Pick the cutting edge. A4 paper cut from the edge of approximately 0.2CM deep, then diagonally cutting, high quality ceramic knife smooth cutting out a small piece of paper width 0.2-0.4CM.
