We supply abrasives products all over the world to a wide range of companies worldwide.
Abrasive material (macro and micro powder) are used for grinding, polishing , cutting, lapping , sandblasting , metallurgical, refractory, foundry and other applications
Vitrified grinding wheels are very professional industrial tools for steel, stainless steel, ceramic , glass, stone work pieces, bearing, crankshaft and camshaft, tool rooms processing, roll grinding , milling cutter, reamers, expanding drills, broaches, paper cutting knife, tobacco cutter, plate-shaped lathe tool, slotting cutter, drill, hobbing cutter, saw-tooth, whatever regular and unregular work pieces.
We always feel that all success of our company is directly related to the quality of the products we offer. They meet the highest quality requirements as stipulated in ISO9001:2008 and our stringent quality control system.
We are capable of offering the most advanced manufacturing capabilities available, including custom molding and machining.
Abrasive powder and grains: we could follow FEPA, JIS, ANSI standard , difference grain shape requirements, extra fine grit for example 6000# ,8000# for some special fields. And grains suitable for bonded, coated , refractories and other applications. More then 20 years experience is very helpful to choice the right material for every application and save cost, such as Brown fused aluminium oxide should be from tilted furnace if used for vitrified grinding wheel to eliminate impurity of SIO2 content, which may result cracks due to 鈥渢hermal expansion coefficient鈥?difference with AL2O3. It can be from fixed furnace if used for resinoid grinding wheel, grinding and cutting discs , even polishing and sandblasting to maintain the quality and save cost. Price of Brown fused alumina made by fixed furnace lumps is more attractive especially fine grit 80# to 220#, furtherly we offer HYP grade and C grade for sandblasting according to various requirements.
Vitrified grinding wheels: we have 2 tunnel kilns with 100meters length to produce huge quantities orders, 700tons capacity per month of each kiln, grinding wheel size up to 1300mm, more then 1000 molds available in toolrooms, very special lab testing instrument to do dynamic testing for those unregular grinding wheels , such as cup, tapered cup wheels, dish wheels. No doubt, every pieces of vitrified grinding wheels must be passed the speed testing to make sure safety except those unregular shape items. we could design open structure grinding wheels (code from 9V to 12V) and micropowder grit grinding wheels available grit 240#–800#. the fine grit grinding wheels are mainly made of white aluminium oxide and green silicon carbide. All grinding wheels moved smoothly between each procedure , they must be packed and printed well immediately inspection be done, and all grinding wheels after packing will be loaded on strong wooden pallet to avoid contaminated.
Resinoid grinding wheel: cold and hot pressed grinding wheel, cover working speed 35m/s to 100m/s , snagging grinding wheel and heavy duty grinding wheels, super fine grinding wheels with grit 240# to 6000# for needle and others.
Grinding and cutting discs: no matter of commercial market and industrial market, we have difference option for you to compete in the market, the grinding wheel we developed for cast iron industry is become very competitive items , such as 400x4x25.4mm, 400x8x40, 400x8x76, 300x6x22.23, 500x10x127, 500x8x76, 600x8x80, high performance and congress against the work pieces, further 180×7 and 230 x7 are popular items for industrial market, which is much difference with commercial market , which required performance more then life circle, and coarse grit should be used only instead of double face grains…
Coated abrasives;No doubt, it is the most popular abrasive production in the world, silicon carbide abrasive cloth roll, aluminium oxide cloth roll , waterproof abrasive paper, dry sand paper, flap discs and the flap fiber backing, nylon backing…
Machinery for making abrasives, this is one of our new business, we could design the regular machines for vitrified grinding wheel and resin grinding wheel, for example multifunction grinding 3 in 1, surface grinding machine, cylinder grinding machine, ball mill, mixer with one or two drums, press machine from 150tons to 3000tons, molding system for auto and semi-auto machine for sharpening stone, machine for mounted point.
We have customers from both domestic market and abroad, Our main sales market:
South America: 20%
Middle east: 20%
North America 10%
