Abrasives industry is a basic industry, but in machining always occupied an important position. For abrasives, there are three remarkable improvement and breakthrough.
First, the abrasive physical structure improvements, such as the role of the workpiece per unit time the number of grains increased,glue stick so that the average length of growth grinding to make grinding contact surface increases, which are changed except the amount of wear per unit of time, effective The improved efficiency; second, super-hard abrasive applications, mainly refers to the metal powder, metal oxide or CBN and other superhard materials as filler, resin, ceramic or metal binding agent made of abrasive applications.
At present,glue gun caused by the super-hard abrasive high-precision, high efficiency grinding effect has been widely recognized; Third, the emergence of new abrasives, such as micron polycrystalline ceramic composed of microcrystalline abrasives, grinding with fine diamond shell abrasive particles, ultra-precision polishing of polyester film tapes. These new abrasives with the characteristics, making it the advantage in grinding are most vividly displayed.
Throughout the development of the field of grinding, grinding of the future will be more demanding Abrasives, to judge from the current situation, super-hard just to meet these new products, grinding needs. CBN abrasives, such as good thermal stability, high hardness, wear resistance and other characteristics, so the abrasive grinding time in the high-speed, high grinding efficiency, grinding life expectancy is high, especially suitable for processing high-speed steel , bearing steel, stainless steel, chilled cast iron and other ferrous metal materials. In addition, to meet the needs of vitrified grinding wheel, grinding wheel speed and the large pores of different processing of different abrasive surface grinding wheel, diamond saw blade so as technology advances will expand the application scope, as the mainstream product in the grinding process .
