The present invention also provides the manufacturing process for the metal bond diamond tool mentioned above. The diamond tool mentioned above is characterized in that the grinding is sharp which can not be blocked and the noise is little; the four sides of the repaired ceramic tiles are level and smooth and the size retention is excellent which makes the side hard to bend; the service life is long which is more than 3 times longer than that of the resin diamond grinding tool of the same specifications; the production cost is low; the sintering temperature is low and energy can be saved; the production cycle is short and the manufacture is convenient.
Description
Technical field:
The present invention relates to metal binding agent diamond tool and manufacture method thereof, especially relate to the finishing that is applicable to relevant material and the aluminium based metal binding agent diamond tool of polishing.
Technical background:
Resinoid bond diamond tool and metal binding agent diamond tool are used for the surface of materials such as glass, pottery or the grinding and/or the grinding (general designation " grinding " later on) of end face always.
Though resinoid bond diamond tool grinding slickness is good, in preparation and use, can work the mischief to environment and operating personnel.And, wearing no resistance, service life is short, easily makes the grinding object produce crimp and causes waste product, needs diamond tool is frequently adjusted, and wastes time and energy.In addition, though the resinoid bond diamond tool is easy to prepare, regelate is time-consuming longer, makes the production cycle long.
Being used for grinding brittle materials such as glass, pottery has with the metallic bond of metal binding agent diamond tool is disclosed: Cu-Sn system, as [patent documentation 1] Japanese kokai publication sho 58-217271 communique, [patent documentation 2] Japanese kokai publication hei 2-76680 communique, [patent documentation 3] TOHKEMY 2001-246566 communique; Fe-Cu-Sn is (as a patent documentation 1), Co-Cu-Sn system (as patent documentation 1 and 3) and Ni-Cu-Sn system (as [patent documentation 4] Japanese kokai publication hei 10-230464 communique, [patent documentation 5] Chinese patent publication number CN1541808A); For Cu-Sn is metallic bond, be to improve the cutting performance of diamond tool, and general Sn composition is more in the bond, and it is shorter to make Cu-Sn bind life-span of mixture diamond tool; Fe-Cu-Sn is the increase of metallic bond with Fe content, the ILS of diamond tool, but after carrying out the wet type grinding, the bond of the diamond tool rust of looking unfamiliar, and it is transferred to and is ground on the material to begin the back in next grinding, produces dirty; Co-Cu-Sn is the metallic bond non-corrosive, but with the increase of Co addition, becomes the scleroma mixture, and cutting is reduced, and the increase of Co content also makes the cost of diamond tool increase greatly in addition.
For Ni-Cu-Sn is metallic bond, prolongs for making the diamond tool life-span, generally sets the Ni amount higher, but with the increasing of Ni content, sintering temperature is higher.For obtaining highdensity sintered body, need apply high pressure at sintering, as use and heat indeformable graphite jig, mould oxidation under HTHP, abrasion are significantly, need frequent updating, and be fit to high-pressure sinter and little heat-resisting alloy or the heat-resisting steels of die change frequency has the sintering temperature upper limit, and make that the content of Ni is restricted in the bond, influence the service life of instrument.
Patent documentation 5 is higher than 40% Ni-Cu-Sn at ni content and adds Ag in the metallic bond sintering temperature of bond is reduced between 650 ℃～850 ℃, can adopt heat-resisting alloy or heat-resisting steels mould to carry out sintering, made the emery wheel that long service life is applicable to grinding brittle materials such as glass, pottery, but that Ni-Cu-Sn-Ag is the metallic bond cost is very high.
Summary of the invention:
The objective of the invention is in order to overcome existing resinoid bond diamond tool short service life, and the shortcoming of disclosed metal binding agent diamond tool, a kind of to have a grinding sharp and provide, grinding skin flatness and slickness are good, long service life, sintering temperature is low, and cost is low, and the Al that has the feature of environmental protection concurrently is metal binding agent diamond tool and manufacture method thereof.
The present invention achieves the above object by following technical solution: novel metal binding agent diamond tool of the present invention is with the basic ingredient of Al as bond, combined with diamond abrasive grain and constituted by metallic bond, described metallic bond comprises following composition (percentage by weight):
