Abrasives three series Features
Mill has bonded abrasives, coated abrasives and superhard abrasive three major series, have their own characteristics, independent existence, their own merits.
Referred to as abrasive grinding tools, grinding has bonded abrasives, coated abrasives and superhard abrasive three major series, have their own characteristics, independent existence, their own merits.
1 abrasive abrasives (grinding material) with a binding agent into a certain shape certain grinding capacity tools. Bonded Abrasives tag example: the shape and size of abrasive particle size binder hardness organization 35M / SGB / T2485 Style Code 300 × 50 × 75 kinds of abrasive grit size bonded abrasives hardness maximum operating speed of the organization No technical conditions abrasive highest standards are lowered working speed standard Abrasives technical conditions, the rest all for abrasive characteristics. Refers to the thickness of the size of the abrasive grit size, consolidation abrasive uses a series of standards, which are based on seven characteristics Abrasives 1998 National Standardization Technical Committee by the State Publishing House of Machinery Industry standard for each requirement.

(1) Hardness: Hardness here refers abrasive external force, binding agents and abrasive bond strength, thickness, respectively, according to the particle size was measured using Rockwell hardness blasting. Sub-super-hardness of the soft (1 super-soft, soft super-2), soft (1 soft, soft 2) soft (a soft, soft 2), (1,2), hard (hard 1 hard 2, hard 3), hard (hard one, hard 2), hard (superhard a superhard 2) and other seven large class of 15 small level.
(2) binding agents: binder refers to all types of binding agents and abrasive abrasive bonding material. Bonded Abrasives usually ceramic, resin, rubber, magnesite four categories binder. This four-binding agent to the largest proportion of vitrified abrasive. The main material is vitrified clay, feldspar, loess, quartz and other components according to different abrasives, different uses and different production method (casting or pressing) different ceramic binder. The main type of phenolic resin binder resins, powder resins liquid resin into two categories, also divided according to the different uses for a variety of different system of law resin binder. Binding agents currently used artificial rubber SBR, Buna rubber and liquid rubber into three categories, depending on the different uses of system of law and is divided into a variety of different rubber binder. Magnesite binders main materials are composed of two materials, magnesium chloride, mainly used for fine-grained abrasive machining purposes. Various binding agents Code as follows: Name of binding agent binding agent codenamed vitrified V resin bonded rubber binder B R magnesite binders Mg (3): Organizing refers abrasive abrasive occupied volume, in weight% ratio. Typically the organization does not show signs of abrasive, while manufacture formulations based system, self-control in Arabic numerals, namely digital smaller, more loose organization, namely the consolidation ratio, the less abrasive, whereas larger organizations figure.
