Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Resin Bond Diamond/CBN Grinding Disc are widely used for high precision, high flatness surface grinding. Resin Bond Diamond/CBN Grinding Disc are wear resistant, uniform density. The surface smoothness can be Raâ?¤0.01um in mirror grinding. The typical artifacts are high-speed steel, valve, flow nipple of oil pump, valve, ceramic pads, touch screen, optical glass, sapphire processing and other precision work pieces grinding.
Features:
Compared to normal size resin bond grinding wheels, big size Resin bond grinding disc have a higher grinding efficiency, because many grinding wheels can be matched together and work simultaneously. Resin Bond Diamond/CBN Grinding Wheels have a special function of the surface is more smooth, so itâ??s usually used for polishing grinding. Besides, it have the features of heat less, not easy to destroy the workpieces. Mainly used in most workpiecesâ?? coarse, semi precision and precision grinding.

Details
The trend in carbide drill / end mill manufacturers is clearly towards high productivity and consistent quality. This has put great demands on the diamond wheel manufacturers to come up with wheels which can grind faster, put less strain on the machine and job that is being ground.
MORESUPERHARD® offers a perfectly matched range of products that allow you to take full advantage of the CNC machine to manufacture your cutting tools. these wheels are made of a new generation bond. hybrid wheels ensure higher material removal without compromising on the surface finish, while ensuring considerable reduction in cycle times. These wheels can be used for both fresh tool manufacturing and re-sharpening, on CNC tool and cutter grinders.
The Unique Properties of the Hybrid Wheels:
Capable of taking higher depth of cuts, high lubrication at the point of grinding, lesser load on the spindle motor, increased profile retention on the wheel, lower grinding force on the work place, which results in lesser work place deflection during grinding.
These Properties of the Hybrid Bond Improve The Performance Of The CNC Tool And Cutter Grinder In The Following Ways:
* Increased rate of material removal with high temperature stability.
* Reduced grinding time per component
* Low and constant power consumption
* High profile stability and better machine productivity

* Mastic compound application consist of two coats of. Primer ,Primer and followed by Mastic compound in recommended thickness, ranging from min. 12mm to 25mm in one or two layers to achieve desired thickness without any pin hole and crack.
1). Surface preparation and application of Primer: Refer application method of Primer.
2). After doing necessary surface preparation and application of primer coating, area to be installed with Mastic compound should be divided in to equal no. bays. To maintain even thickness required, place wooden or aluminum batten. Mastic compound is then broken in small pieces and put it in heating pan. While heating, keep material moving to avoid burning. It is heated until it comes in a uniform consistency and then applied on the surface and works it with wooden float, to achieve uniform thickness and smooth surface free from any pinholes.
CHEMICAL RESISTANCE PROPERTIES:
* Mastic compound has good resistance to weak, diluted acids, alkalis salts etc. It is not recommended to use against strong acids, oxidizing acid solvents, oil and fats
STORAGE & PACKING:
* Keep Mastic compound away from direct sunlight, heat solvents etc. Under this condition, its shelf life is unlimited. It is supplied in cake form and approx. wt. is 10 kgs.
