Description
Technical field
The present invention relates to a kind of hardness height cutter for numerical control cutting equipment.
Background technology
Along with the development of new technology revolution, require improve constantly machining productivity ratio and reduce production cost., the particularly development of Digit Control Machine Tool, requires the new-type cutter that exploitation is higher than hard alloy cutter cutting speed, more wear-resisting.A few days ago various high strength, high rigidity, corrosion-resistant, wear-resisting and resistant to elevated temperatures be difficult to cut new material increasing.Estimate according to document, this kind of material oneself account for and process more than 50% of sum in the world., hard alloy cutter to the difficult processing of wherein many new materials with competent.On the other hand, now in the world carbide alloy output oneself reach 20000-25000t.The metal that annual consumption is a large amount of, as W, Co, Ta and Nb etc.The mineral resources of these metals reduce just day by day, rise in price, press depletion rate a few days ago, have more than is needed decades. and some resource will exhaust.Sintex is exactly grow up in this context.
As far back as 1912-1913. Britain and Germany oneself there is alumina tool, but its application on producing then starts from nineteen fifty.Because its intensity, toughness are low, are only limitted to do continuous cutting fine finishining in the long term and use., and cutting speed and the amount of feeding are all lower.Until 2nd generation sintex-composite alumina cutter just appears in nineteen sixty-eight, intensity and toughness are significantly improved than aluminum oxide tool, various workpiece can be cut under higher speed and the larger amount of feeding. obtain and apply more widely.
Late 1970s to the beginning of the eighties world occurred the 3rd generation sintex-Silicon Nitride Ceramic Cutter.This kind of Stupalox has toughness, impact resistance, elevated temperature strength and the thermal shock resistance higher than composite alumina cutter.Ceramic tip is very fast in the increase of production of each industrially developed country.
China starts to produce composite alumina blade in batches in the sixties in 20th century, and current year output is 14-15 ten thousand.Though silicon oxide ceramics blade just begins one's study in 20 century 70s, due to poor performance, can not satisfy the demands.In recent years, along with deepening continuously to high-temperature structural ceramics area research, make the performance of silicon nitride ceramics have large increase, thus Silicon Nitride Ceramic Cutter is developed rapidly in China.
Summary of the invention
The invention provides one, to have hardness higher, the hardness height cutter for numerical control cutting equipment of toughness and the better advantages of comprehensive mechanical property such as tired.

A kind of hardness height cutter for numerical control cutting equipment of the present invention, has hardness higher, the good advantages of comprehensive mechanical property such as toughness and fatigue.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, the described hardness height cutter for numerical control cutting equipment is combined by metal-base composites, fiber plastification material and chilled cast iron, described metal-base composites comprises carborundum, boron, aluminium oxide and carbon fiber, described metal-base composites occupies the 64%-69% of the overall component of hardness height cutter of numerical control cutting equipment, described fiber plastification material occupies the 5%-8% of the overall component of hardness height cutter of numerical control cutting equipment, and described chilled cast iron occupies the 22%-30% of the overall component of hardness height cutter of numerical control cutting equipment.
Further illustrate, described fiber plastification material comprises polypropylene fibre, described metal-base composites occupies 67% of the overall component of hardness height cutter of numerical control cutting equipment, described fiber plastification material occupies 6% of the overall component of hardness height cutter of numerical control cutting equipment, and described chilled cast iron occupies 27% of the overall component of hardness height cutter of numerical control cutting equipment.
Further illustrating, polypropylene fibre has that intensity is high, good toughness, chemical-resistant and microbial resistance are good and the advantage such as price is low, is therefore widely used in the industrial field such as reinforcing material of rope, fishing net, safety belt, case and bag band, safety net, sewing thread, cable sheathing, geotextiles, filter cloth, paper grade (stock) felt and paper.The polypropylene woven geotextile that the good characteristic such as utilize polypropylene fibre intensity high, acidproof, alkaline-resisting, antimicrobial, dry wet powerful equally manufactures, reinforcement effect can be played to the civil engineering be built on soft soil foundation (as dykes and dams, reservoir, highway, railway etc.), and make bearing load uniform distribution in geotextiles, make subgrade settlement even, reduce polygon ground.When building slope, adopt woven polypropylene geotextile can stabling slope, reduce caving in of slope, shorten construction period, extend the service life on slope.Carry comparatively heavy load time, the composite earthwork cloth that woven geotextile and non-weaving cloth are matrix can be used.Polypropylene fibre can be used as the packing material of concrete, plaster etc., improves concrete impact resistance, waterproof and heat-insulating.Along with the fast development of chemical industry, environmental protection, New Energy Industry, as filtering material, polypropylene fibre has good prospect of the application, and new technology makes that polypropylene fibre filter efficiency is high, intensity is high, light weight, to chemicals good stability, screening fissility is good.Therefore, in industries such as pharmacy, chemical industry, environmental protection, batteries as functional products such as hydrophilic barrier film, ion exchange membranes, having good growth momentum, is the novel high-tech product promoting polypropylene fibre added value.
Further illustrating, metal-base composites (MetalMatrixComposite, MMC) is generally take metal or alloy as continuous phase and particle, the composite of the second-phase composition of whisker or fibers form.Its preparation and fabrication is more difficult at present, and cost is relatively high, is commonly used in space flight and aviation and war industry.Present composite production and processing technology is relatively ripe, and civilian, commercial kitchen area all has use.[1]
Metal-base composites terms of mechanics feature: transverse direction and shear strength higher, advantage: damping and amortization is good, non-hygroscopic, not aging, serviceability temperature scope 350 ~ 1200 DEG C, its feature is that transverse direction and shear strength are higher in terms of mechanics, the comprehensive mechanical properties such as toughness and fatigue are better, advantages such as also having heat conduction, conduction simultaneously, wear-resisting, thermal coefficient of expansion is little, damping and amortization is good, non-hygroscopic, be not aging and pollution-free.Such as its specific strength of fibre reinforced aluminium composite material 3 ~ 4 × 107mm, specific modulus is 6 ~ 8 × 109mm, and for example graphite fibre strengthen magnesium not only specific modulus can reach 1.5 × 1010mm, and its thermal coefficient of expansion is almost close to zero.The invention provides a kind of hardness height cutter for numerical control cutting equipment, there is hardness higher, the good advantages of comprehensive mechanical property such as toughness and fatigue.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
