Coal mine with PDC manufacturers: Henan SFD superhard materials Co., Ltd.! SFD MT series designed specifically for the coal mining drill, its superior price by domestic and foreign customers a wide range of ages. Diamond carbide composite sheet is a composite material consisting of diamond and tungsten carbide substrate, with high hardness, wear resistance characteristics, widely used in oil drilling, geological exploration, coal drilling field machining tools, drills and . The adoption of new efficient catalysts and new technology, designed for the pursuit of cost and efficiency of the market and specially designed and developed coalfields series PDC. With good wear resistance, footage, high efficiency, low disintegrating tablets and economical advantages. Mainly used in coal, mining PDC drill bit manufacturing. Spherical diamond carbide composite sheet is developed on the basis of flat teeth PDC on new composite sheet. Not only has high hardness, wear resistance characteristics, but higher than the flat sheet rock in the reliability of high hardness, disintegrating tablets less effectively improve the life and reduce drilling costs. Can be widely used in geological prospecting, ground Ji Luji drilling, coal drilling bits and other fields. Suitable for harder formations. Flattened spherical diamond tooth carbide-based composite sheet is spherical and flat teeth tooth PDC PDC on the latest research and development of composite sheet. High speed footage also has flat teeth tooth hardness and spherical fast, easy disintegrating tablet features. Faster than the speed of spherical teeth footage and high efficiency; planar sheet in use at high hardness formations higher reliability, less disintegrating tablets, wear ratio. Can reduce drilling costs. Can be widely used in geological prospecting, ground Ji Luji drill. Coal drilling bits and other fields. Suitable for harder formations.
