Abstract
A tool with a single layer of soldered diamond particles is prepared from abrasive diamond particles, metallic base, and low-temp solder through HF induction heating in air.
Description
Technical field
The present invention relates to a kind of preparation method of single layer soldering diamond tool, prepared diamond tool is applicable to granite, pottery, the processing of hard brittle materials such as concrete and glass.
Background technology
Present existing diamond tool can be divided into individual layer usually and electroplate and multi-layer sintering (comprising heat cure) two big classes, because the diversity and the complexity of actual grinding operation, individual layer and multilayer instrument have his own strong points, and wherein the individual layer plating diamond tool is made easily because electroplating technology is simple; Need not to repair dressing, easy to use, therefore in the production application of diamond tool all always in occupation of very big share.But owing to all do not exist firm chemical metallurgy to combine on the interface of coated metal and the abrasive material and the grinding tool matrix of electro-deposition on the plating diamond tool.Abrasive material just mechanically is embedded between coating and the matrix, so the coat of metal is little to the hold of diamond abrasive grain, as easy as rolling off a log because of abrasive material come off and coating peel off the global failure that causes emery wheel in flakes.In addition, because coating is thick, the abrasive material proud exposure is low, and chip space is little, is easy to during the electroplating abrasion wheel grinding lose efficacy because of the adhesion obstruction of smear metal.Simultaneously, the effective rate of utilization of abrasive material itself is also extremely low on the electroplating abrasion wheel.
Abroad begin one's study in the early 1990s and replace electroplating Development of New Generation single layer soldering diamond tool with soldering, by high temperature brazing make that solder dissolves on diamond abrasive grain and metallic matrix interface, thereby the interaction of diffusion, chemical combination and so on improves the hold of matrix to diamond abrasive grain, improves the bond strength between abrasive material, bond (brazing filler metal alloy), the matrix three.The high temperature brazing diamond tool is to carry out in the high temperature vacuum brazing stove substantially at present, and metallic matrix has been realized whole heating, and programming rate is slow, and the tool manufacture time is long, owing to need vacuum, so equipment investment is big.Though can realize also that by this brazing mode the high strength of diamond abrasive grain is fixed, the preparation method complexity, the preparation cost height, required time is long.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of preparation efficiency height, single layer soldering diamond tool that preparation cost is low.
Technical scheme of the present invention is such: a kind of preparation method of single layer soldering diamond tool, heating soldering under the effect of solder forms by diamond abrasive grain and metallic matrix, above-mentioned brazing process carries out in air, and the solder that is adopted is a low-temperature brazing filler metal, and the heating of the soldering in the above-mentioned brazing process is carried out in the mode of high-frequency induction.
The percentage by weight of above-mentioned low-temperature brazing filler metal ingredient is Ag:25-30%, Cu:35-40%, and Zn:31-37%, Cr:5-10%, its fusing point are 740-760 ℃.
In the above-mentioned brazing process, adopt high-frequency induction welder to heat.
The preparation method of a kind of single layer soldering diamond tool of the present invention uses high-frequency induction heating to shorten heat time heating time greatly, thereby has improved the preparation efficiency of instrument; And because aerobic in the air, under high-temperature condition, can produce oxidative damage to diamond abrasive grain, the present invention uses high-frequency induction heating, and use low-temperature brazing filler metal, like this, soldering is short heat time heating time, therefore can significantly reduce the fire damage and the oxidative damage of the diamond abrasive grain that causes owing to high temperature in the brazing process; The local heating that uses high-frequency induction heating can also realize matrix promptly only heats in the place that needs braze welding diamond abrasive grain, realizes the welding of diamond abrasive grain, has avoided the integral body of metallic matrix to be heated like this, reduces the fire damage to metallic matrix., compare simultaneously, do not need vacuum to make instrument with soldering in the common vacuum because brazing operation carries out in air.When producing investment, need be in the investment of vacuum equipment.When the preparation instrument, owing to do not need to vacuumize, therefore can further shorten preparation time, improve the preparation efficiency of instrument.
The proud exposure abrasive particle of the resulting diamond abrasive grain of diamond soldering appliance preparation method of the present invention can remain on more than 70% of abrasive particle particle diameter.Can give full play to the excellent properties of every diamond abrasive grain like this.
Use this diamond doctor technology of preparing manufacturing diamond soldering appliance, the preparation efficiency height, abrasive particle proud exposure height adds man-hour carrying out heavy load, owing to can be realized to the hard brittle material highly-efficient processing of (comprising pottery, stone material, concrete and glass etc.).
The specific embodiment
The preparation process of a kind of single layer soldering diamond tool of the present invention is as follows:
One, applies the very thin gluey low-temperature brazing filler metal of last layer uniformly at metal base surface, the percentage by weight of this low-temperature brazing filler metal ingredient is Ag:25-30%, Cu:35-40%, Zn:31-37%, Cr:5-10%, the fusing point of this low-temperature brazing filler metal are 740-760 ℃;
Two, diamond abrasive grain is placed on the metallic matrix that is coated with gluey low-temperature brazing filler metal in the step 1 as required, places briquetting at metal base surface then, push down diamond abrasive grain;
Three, with high-frequency induction welder the place that needs braze welding diamond abrasive grain on the metallic matrix in the step 2 is heated in air, when being heated to the low-temperature brazing filler metal fusing, can stop heating, cooling has realized that so just the soldering of diamond abrasive grain is fixed naturally.
Design main points of the present invention are carried out soldering for use the mode of low-temperature brazing filler metal and eddy-current heating in air, the size of the temperature and time of soldering heating and the instrument of manufacturing, the size of diamond abrasive grain, the selection of solder, the size of soldering area, multiple factors such as the power of high-frequency induction welder are relevant.
Among the present invention, soldering adopts high-frequency induction welder to heat, and uses high-frequency induction heating to shorten heat time heating time greatly, thereby has improved the preparation efficiency of diamond tool., compare simultaneously, do not need vacuum to make instrument with soldering in the common vacuum atmosphere because brazing operation carries out in air.When producing investment, need be in the investment of vacuum equipment, preparation cost is lower, and when the preparation instrument, owing to do not need to vacuumize, therefore can further shorten preparation time, improves the preparation efficiency of instrument.
