Description
Technical field
The present invention relates to a kind of abrasive cut-off wheel, particularly relate to a kind of ultrahigh speed fiber enhanced resin cutting grinding wheel.
Background technology
Grinding materials and grinding tool industry is the important indispensable industry of in machine tool industry, and its product is widely used in all trades and professions in processing manufacturing industry, and the application related in recent years is continuously available extension.
Along with developing rapidly of the industries such as domestic and international machine-building, building materials, objectively require that grinding materials and grinding tool adapts with it, emery wheel as the major product of the industry of grinding tool abrasive material, its cutting and sanding property high-quality, efficient, safe, product are multiplex, cost degradation is just becoming the general character requirement of industry and enterprise. The emery wheels such as China's iron and steel, automobile, lathe, agricultural machinery, bearing, shipbuilding, railway and Aero-Space make the surging development of the industry that consumption is intensive, the consumption that makes of emery wheel is increasing year by year, be phased out wearing no resistance plus domestic and international enterprise customer, lifetime is short, traditional emery wheel of poor stability, then adopt super abrasive, super-long service life, an ultra sharp, can grinding cut composite wheel new product.
Domestic and international emery wheel product, after most of cutoff wheels all adopt emergy to mix with binding agent, compacting hardening forms, and it is shaped as disk in uniform thickness, centre perforate. During work, the grinding wheel of high speed rotating contacts with material to be cut, and applies certain pressure, owing to emergy hardness is higher than metal, thus reaching the purpose of cutting metal. Adopting conventionally produced emery wheel, sharp be not durable, interior tissue density is relaxed, and drop is fast, and wear-resisting durable emery wheel is not sharp. Tightlier, wheel face, workpiece of easily burning are blocked in chip removal to interior tissue density, and the cutting fricative heat of metal object makes the temperature of cutoff wheel raise rapidly, thus has damaged the mechanical strength of cutoff wheel, shortens the service life of cutoff wheel.
Summary of the invention
For this, comprehensive grinding materials and grinding tool production technology both at home and abroad, and experience and lessons, my company is on the basis of innovation, use intellectual property " a kind of high intensity can grind cutting abrasive wheel " and " can grinding abrasive cut-off wheel " patented technology of autonomous innovation, by resinoid bond is modifiied, strengthen Wheel hardness, revolving strength, improve emery wheel cutting power; By increasing glass fiber net resin content in emery wheel, improve emery wheel elasticity further, make every abrasive material on grinding wheel can repeatedly carry out sharp grinding, improve the grinding function of emery wheel.
In order to solve the problems referred to above, the present invention provides the ultrahigh speed fiber enhanced resin cutting grinding wheel that a kind of simple in construction, bulk strength are high, skin-friction force is big and solid capacity is big.
The ultrahigh speed fiber enhanced resin cutting grinding wheel of the present invention, including emery wheel main body, the middle part of emery wheel main body is provided with centre bore, described emery wheel main body is provided with triplex glass fibrous mesh cloth, triplex glass fibrous mesh cloth lays respectively at the end face of emery wheel main body, middle part and bottom surface, and is combined with each other with emery wheel main body.
Further, the buffed surface of emery wheel main body is provided with opposite to the direction of rotation to involute pattern groove.
Further, the order number of described fiberglass gridding cloth should match with the granularity of abrasive material in emery wheel main body.
Further, the thickness of described fiberglass gridding cloth and grinding wheel thickness match.
Further, the amount of resin on described fiberglass gridding cloth is no less than 31%.
Further, the amount of resin on described fiberglass gridding cloth is no less than 31%.
Further, the external diameter of described emery wheel main body is 75-300mm, and thickness is 1.3mm-2.5mm, and the diameter of centre bore is 16mm.
Compared with prior art, the invention have the benefit that 1, be provided with on grinder buffing face opposite to the direction of rotation to involute pattern groove, wheel strength and skin-friction force and solid capacity can be strengthened, efficiently solve the technological difficulties that cutting can not carry out simultaneously with polishing burr, during stone, heat radiation is easier to, chip removal is more convenient, every sand can adjust best sand fallout state, produce repeatedly new acute angle, repeatedly carry out sharp grinding, accomplishing that every sand on emery wheel is finished to use up, the flour milling life-span is greatly prolonged. 2, emery wheel main body is through being composited by the abrasive material of 70%-86%, 7%-19% bonding agent and 5%-12% filler. Emery wheel is heat-resist, and intensity is high, and much powder of filler is thin, and dispersion flows is good, reacts under grinding temperature, reduces emery wheel to greatest extent slow and skid, improves the grinding performance of emery wheel further, strengthen durability and the sharpness of abrasive cut-off wheel. Adjust phenolic resin composition, heat decomposition temperature is brought up to about 410 degree, so that stone speed is from 60��80 meter per seconds, brings up to more than 120 meter per seconds, improve more greatly emery wheel cutting power. 3, the present invention uses three-layer mesh fabric, with the supporting molding of caoutchouc elasticity mould, uses linear velocity to reach 120 meter per seconds, is suitable for multiaxis high-speed machine tool and uses. Emery wheel safety improves 100% (bringing up to 120 meter per seconds from 60 meter per seconds), thermal diffusivity is better, cut sharper quickly, workpiece otch is not burnt, is not aoxidized, save machined material and the material of emery wheel own, a more than feed 3mm is used at multiaxis high-speed machine tool, the hard material deep trench processing such as particularly suitable mould steel, tool steel, improve machining efficiency, it is more notable than the cost of charp tool saved by the cutters such as expensive rare earth alloy cutter, diamond, adaptive surface is more extensive, has good economic benefit and social benefit.
