How to grind ceramic knife ?

Ceramic knife, Ceramic knife) is started using a new type of kitchen utensils and appliances in recent years, high purity superfine zirconia powder is used as raw material, under the condition of the high temperature of one thousand degrees, the spray granulation, isostatic pressing molding, precision machining and other process manufacturing, and has high hardness, strong corrosion resistance, good chemical stability, high wear resistance, high toughness and other characteristics.  Beautiful and exquisite in appearance, with sharp edge, it is a real knife that never wears and never corrodes.  The sharpness of the blade is more than ten times that of the steel knife. This kind of knife is the product of modern science and technology, and has the superiority that the metal knife can’t match before.

Most ceramic knives on the market are made of zirconia, a nanomaterial.  Zirconia and alumina powder was used to press the tool blank with 300 tons of pressure and mold, and then sintered at 2000 degrees Celsius. After grinding with diamond, the finished ceramic knife was made with the tool handle.  Ceramic blade is a new type of blade made of high-tech nano technology, sharpness is more than ten times that of steel knife, so the ceramic knife has high hardness, high density, high temperature resistance, magnetization resistance, oxidation resistance and other characteristics.  It has a Mohs hardness of 9, so if it doesn’t fall to the ground, doesn’t get hit by external forces, doesn’t cut, it doesn’t need to be sharpened.  Generally manufacturers will mix metal powder on the blade, metal detectors can detect ceramic knife.

Ceramic knife has the advantages: wear resistance, high density, high hardness, no dirt, no metal taste residue when cutting food, easy to take and easy to cut, etc. There are many irreplaceable advantages of metal knife.  Ceramic knife can only cut some vegetables, sashimi, meat, seafood and other non-rigid food, cutting food will not have a metallic taste.  Its hardness is high, manufacturing process improved, can withstand a certain impact, use should be careful, so as not to hurt yourself, its sharpness is incomparable to the steel knife.

Most of the ground ceramic components will have various types of surface or subsurface damage, due to the high hardness and brittleness of ceramic materials. This will lead to a reduction in the strength of the ceramic components and limit the use of large material removal rates. The fundamental goal is to obtain the maximum material removal rate while maintaining the surface integrity and dimensional accuracy of the material for high-efficiency ceramic grinding.

The grinding of ceramic Knives requires the maximum material removal rate while maintaining the surface integrity and dimensional accuracy of the material. Moresuperhard selects sharp abrasives and strictly controls the size of abrasive particles to avoid mixing large abrasives, so as to solve the problem of easy scratches on the surface of ceramic knives and clogging of the grinding wheel during fine grinding.
