Fiberglass disc is punched from fiberglass cloth for grinding wheel which coated with phenolic and epoxy resin .when necessary , coating with non-woven fabric .black paper. It is the best base material for resin bond grinding wheel with the features of high tensile strength and deflection resistance, it is nice performance to link up with abrasive. Meanwhile, it is the features of excellent high-speed cutting resistance and heat resistance.
Taking EG190-6.5*5.4/178*23V+W for example :
Expression of the cloth same as above;
OD: outside diameter is 178;
ID: inside diameter is 23;
Surface: V+W means coated with non woven fabric + wax paper(W means wax paper; P means coated with black paper; B means black color.)
The E-glass fiber grinding wheel reinforced meshes have features of light weight, high strength, good flatness, low elongation, heat-resistant, wear-resistant and non-toxic and tasteless, meeting the demand of customer automation equipment current and upgrade etc. The wheels made by this material have excellent safety, good flatness, abrasive resistance, heat resistance, and also resistant to high -speed cutting performance etc
The main technical performance indicators as follows
Element Comparison between C-glass & E-glass
E-glass Reinforced Material For Grinding Wheel Advantage
Thinner discs, Higher specific strength, More uniform strength
Take EG6.5*5.4-190 as example
2. Perfect appearance
(1)Keeping flat long time
(2)Meshes more clear and square
(3)The edge is not easy to loose
(4)Meeting the demand of customer automation equipment current and upgrade
3.Better performance of grinding wheels
（1）Wheel 355*2.8*25mm test data (Jiuding EP8*8-260 )
（2）Jiuding VS Domestic counterparts, Wheels 115*6.4*22mm , 6 months’ burst speed tracking
JIUDING fiberglass cut pieces have unparalleled high-intensity with similar products as a result of the unique composition and surface treatment technology which provide excellent product quality assurance a for all types of grinding wheel.
Reinforced resinoid cut-off wheels
Using high strength fiberglass cut pieces as base material, the wheels will have stable quality with excellent flatness, good safety, bending resistance, little dust, tasteless, conform to the environmental protection standard, also have high efficiency and long life. Reinforced cut-off wheels are used for cutting various types of materials.
Reinforced resinoid DC wheels
Using high tensile strength fiberglass cut pieces, the wheels have ability for good safety and abrasive resistance. DC wheels can be used in a variety of industries.
（1）Specification to choose
The appropriate specifications of fiberglass cut pieces are selected by mesh size, weight per square and structure according to types, dimensions, requirement for the line speed of the reinforced bond grinding wheel. Generally determined by design of the technicians in the grinding wheel factory and through the blasting test.
（2）Resin to choose
The selection of the resin is considered by bonding strength of fiberglass cut pieces and grinding wheel commonly use phenolic resin, also can design of resin according to requirement of special customers.
（3）Surface to choose
The selection of the surface is considered by appearance of grinding wheel and processing equipment for producing grinding wheel, plain fiberglass cut pieces are usually as internal mesh for grinding wheel. Fiberglass cut pieces with black paper and non woven fabric are usually as external mesh for grinding wheel.
（4）Color to choose
The selection of color is considered by appearance requests of grinding wheel. Normally have two colors: light yellow and black, also can supply other colors according to customer’s requirement.
Our company have whole chains of production of fiberglass cut pieces from furnace drawing, weaving, impregnation and punching, also have ability to design fabric specification and R&D of resin performance and treatment, can design and produce according to customer’s special requirement on specialty abrasives.
