Abstract
The invention belongs to optical glass fine finishining diamond tool technical field.The present invention adopts nickel aluminum metal bond, and prepared glass fine-grinding sheet is good with the wellability of bortz powder, is better than copper based anchoring agent and iron-binding agent, and the life-span doubles, and close with the cobalt base bonding agent life-span, but price is lower by about 10% than cobalt base bonding agent.The cobalt-based precise abrasive plate that can replace the existing market upper inlet.
Description
The invention belongs to optical glass fine finishining diamond tool technical field.The optical glass precise abrasive plate begins development abroad at the beginning of the seventies.China is then in " 4.5 " development of tackling key problems in the works.Press metal bond branch, existing Co base precise abrasive plate, Fe base precise abrasive plate and Cu base precise abrasive plate etc.(＜Prwder Metallurgy Principles and Applications＞Prince-ton, New Jersey 1980; Russian Patent: No.963804).At present, main Cu base smart sheet (homemade) and the part import sheet (Co base precise abrasive plate) of using on the domestic market.Ni-Al binding agent precise abrasive plate of the present invention at home and abroad there is no this product.Advantage of the present invention is: the wellability of (1) Ni-Al binding agent and bortz powder is better, is better than Cu based anchoring agent and Fe based anchoring agent; (2) adopt the fine-grained bond powder of＜360 orders, improve sintering character; (3) the bond composition is simple, and price is more cheap and a little more than the Cu based anchoring agent than Co based anchoring agent; (4) service life is near Co base precise abrasive plate (American movie).Be better than Fe base precise abrasive plate (day this film) and Cu base precise abrasive plate (Hong Kong sheet, domestic film).All there is different shortcomings in present existing precise abrasive plate, and the Cu based anchoring agent is low because of hardness, wear no resistance, and reduce service life, and the Fe based anchoring agent is more crisp, the higher increasing production cost of Co based anchoring agent price.Ni-Al binding agent precise abrasive plate of the present invention has solved the weak point of these three kinds of precise abrasive plates, property result on probation proves: Ni-Al binding agent and bortz powder wellability are good, double than copper based anchoring agent and the agent of iron-based knot service life, and be close with cobalt base bonding agent, but price reduces about 10% than cobalt base bonding agent.
It is the principal component of bond that the present invention adopts Ni, Al metal dust, and nickel powder accounts for 80-98% by weight percentage, and aluminium powder accounts for 2-20%.This mixed metal powder is mixed with bortz powder, and the concentration of bortz powder is good in the 30-70% scope in the precise abrasive plate.Add an amount of forming agent then, the extrusion forming sintering makes the aluminium base glass fine-grinding sheet of nickel.
According to the demand difference of using, also can in nickel, aluminium master metal powder, add the doping powder of 0.1-5%, as iron, copper, zinc, tin, cobalt, chromium, silicon, carbon etc.A kind of, two or more this class powder can mix.
Descend because bortz powder concentration is crossed the low precise abrasive plate grinding capacity that can make, excessive concentration then increases unnecessary waste and simultaneously grinding quality be there is no benefit, so add the amount of bortz powder, is the best with diamond concentration in precise abrasive plate at 35-50%.
Nickel powder of the present invention can be electrolytic nickel powder or hydroxyl nickel powder or reduced nickel powder etc.The granularity of nickel powder aluminium powder or other adulterated flours should be lower than 360 orders, and optimal granularity is 1 μ-10 μ.
Technological process of the present invention is as follows:
With granularity less than 360 purpose nickel shots, aluminium powder by weight percentage nickel be 80-98% batching.Add any one diadust among W10, W14, W20, the W28 (is 30-70% in diamond concentration in the precise abrasive plate) again.With an amount of forming agent, mix the back extrusion forming, pressure be the 4-8 ton/centimetre
2Sintering under nitrogen atmosphere, sintering temperature 850-1200 ℃, sintering time 1-4 hour.Or for making the precise abrasive plate scope of application wider, in nickel, aluminum metal bond, add in the powder such as iron, copper, tin, zinc, cobalt, chromium, silicon, carbon of amount by weight percentage any again, it also can be two or more this doping powder, mix with bortz powder again, it is measured in diamond concentration in the precise abrasive plate in the 30-70% scope, add an amount of forming agent again, pressure be the 4-8 ton/centimetre
2Following extrusion forming, under nitrogen atmosphere in 850-1200 ℃ of sintering, sintering 1-4 hour.The mixed method of powder can adopt dry type also can adopt wet type, and it is 1-24 hour that mechanical agitation, time are promptly used in the dry type mixing.Wet mixed can be used alcohol organic solvent, or the aqueous solution that contains dispersant (as hexametaphosphate) makes medium, stirs 0.5-4 hour.
Said alcohols solvent can be used methyl alcohol, ethanol, propyl alcohol and polyalcohol, and the alcohol organic solvent aqueous solution of alcohol organic solvent (or contain) is good to the wellability of metal powder, bortz powder, itself is easy to volatilization, and is better than the aqueous solution as medium.
The bond powder can mix separately earlier, also can be mixed together with bortz powder.
The pressure of extrusion forming, optimum range be the 5-7 ton/centimetre
2, the sintering temperature optimum range is 950-1100 ℃.
Forming agent can be used zinc stearate, paraffin wax, lithium stearate, resin and ammonium chloride etc.The forming agent 0.1-1% of measuring the bond amount.
