Wear problems: Any grinding wheel has a certain use wear requirements, wear a certain degree of must replace new cutting wheel
Of the wheel. Not in order to save material, ultra require the use of wear and tear, which is an extremely unsafe illegal behavior. A
General provisions, the new wheel should be replaced when the grinding wheel wear large diameter 10mm in diameter than the chuck. Valid question: New grinding wheel collar from the Treasury is not necessarily qualified wheel, new grinding wheel even buy from manufacturers is not necessarily qualified
Of the wheel. Any abrasive wheel has its valid use within the expiration date, it is qualified grindstone; exceeds
Valid for use, it is not necessarily qualified wheel. Rules of order, "the grinding wheel should be used within the validity period, resin and rubber
Cementation agent grinding wheel storage rotation test after one year, must be approved by the eligible applicants before use ". Texture problems: Wheel local crack during use, should immediately stop using the re-replacement of the grinding wheel, diamond grinding
Diamond tools, diamond grinding wheel grinding tungsten carbide, glass, Hone stone, precious stones and high hard and brittle material effects tools. In recent years, with the rapid development of ultra-precision grinding technology for high speed grinding, grinding wheel, higher demands, ceramic and resin bonded grinding wheel can not meet the production needs metal bonded grinding wheel because of its combination of high strength and good formability long life and other significant characteristics and production has been widely used. Metal bond diamond wheel manufacturing methods mainly have the sintering, plating two types. Abroad starting from the early 1990s in order to give full play to the role of super abrasive, high temperature brazing process to develop a new type of grinding wheel, ie the monolayer high temperature brazing grinding wheel, currently this grinding wheel is still in the research and development stage. Can adapt to various ceramic diamond grinding wheel vitrified bond diamond wheel with diamond and ceramic binder common characteristics, compared with ordinary corundum, silicon carbide grinding wheel, grinding power, grinding temperature is relatively low, the small wheel wear; types of cooling liquid; grinding grindstone shape maintaining high precision grind the workpiece; the grindstone there are larger pores, grinding conducive chip removal and cooling, clogging, easy to burn the workpiece; grindstone better since sharp trimming interval for a long time, relatively easy trimming. Therefore, the increasing use of vitrified bond diamond wheel in some foreign countries.
