Abstract
A superhard grinding tool is prepared through using the glass or ceramics with low smelting point to adhere the coating material onto surface of abrasive particles, mixing with the powdered ceramic binder, and cold (or hot) pressing, and sintering. Its advantages are long service life and high efficiency.
Description
The present invention relates to a kind of ceramic bond super-hard abrasive tool and manufacture method thereof.
In traditional ceramics bond super-hard abrasive tool manufacture method, generally be that diamond or cubic boron nitride are joined in the powdery vitrified bond with certain proportion, the mould of packing into after fully mixing, compression moulding under room temperature condition then reenters the stove sintering; Or the dress mould is placed in the sintering temperature environment compacting and carries out simultaneously with sintering; The grinding tool of above-mentioned two kinds of traditional handicraft manufacturings makes abrasive material damage owing to abrasive material is subject to the etch of bond high temperature: smooth abrasive surface makes abrasive material be easy to non-grinding to come off, cause the grinding tool life-span short, efficient is low; The coefficient of expansion of abrasive material and bond differ bigger, in the cooling contraction process abrasive particle and bond bonding part are cracked.
The object of the present invention is to provide a kind of ceramic bond super-hard abrasive tool and manufacture method thereof, the super-hard abrasive tool of this method manufacturing is compared with the grinding tool of traditional handicraft manufacturing, has long service life and production efficiency advantages of higher.
This ceramic bond super-hard abrasive tool and manufacture method thereof is characterized in that: with low-melting glass or ceramic 3 coating material 2 is bonded in abrasive material 1 surface; Then, the abrasive material 1 usefulness vitrified bond powder of surface-coated is mixed, then, with cold pressing-method of sintering or hot pressing-sintering makes super-hard abrasive tool; The coating material 2 on said abrasive material 1 surface is corundum, cubic boron nitride, diamond or carborundum; Said as binding agent low-melting glass or the weight of the coating that constituted of pottery 3 and coating material 2 corundum, cubic boron nitride, diamond or carborundum be equivalent to 5～200% of abrasive material 1 weight; The main component of vitrified bond is SiO
2, Al
2O
3, B
2O
3, Na
2O, Li
2O, MgO, ZrO
2, when needing, add Ti, Al, Ni, Mo, W, Cr metal.
The super-hard abrasive tool of Zhi Zaoing efficient and life-span in grinding all increase substantially in this way, and its main cause is: because abrasive surface coating protection abrasive material is not subjected to the etch of bond; The scraggly surface of coating has also increased the contact area of abrasive particle and bond, makes abrasive particle reduce non-grinding and comes off; The composition that is the abrasive surface coating helps abrasive particle and bond good combination; The abrasive surface coating helps the adjustment of the bond and the abrasive particle coefficient of expansion, makes to reduce the chance that occurs crackle between abrasive particle and the bond in its sintering cooling procedure.
