Abstract
The invention relates to the field of abrasive tools, in particular to a manufacturing method of abrasive blocks for a superhard material grinding disc and a manufacturing method of the superhard material grinding disc. The manufacturing method of the abrasive blocks for the superhard material grinding disc includes the steps of 1, manufacturing base blocks of the abrasive blocks; 2, cutting the base blocks of the abrasive blocks, obtained in step 1, to obtain at least two abrasive block blanks of the abrasive blocks to be manufactured. The base blocks of the abrasive blocks are as thick as the abrasive blocks to be manufactured; in addition, each base block of the abrasive blocks can be cut into at least two integral abrasive blocks of the abrasive blocks to be manufactured. The abrasive blocks of various specifications can be manufactured with uniform molds, and production cost of the abrasive blocks is lowered; meanwhile, by the use of the cutting method as compared with one-by-one molding method, efficiency of manufacturing the abrasive blocks can be greatly reduced. The problem that the abrasive blocks for the superhard material grinding disc are high in manufacturing cost and low in manufacturing efficiency is solved.

Be subject to the impact of mill operating characteristic, in use, due to Internal and external cycle linear velocity difference, it is fast that the abrasive material piece that is positioned at mill outer ring place is positioned at the depletion rate of abrasive material piece at mill inner ring place, in order to address this problem, normally adopt the method for arranging different size abrasive material piece at the Internal and external cycle of mill, make in addition the arrangement mode variation of abrasive material piece, synchronously wear away to the abrasive material piece of realizing mill Internal and external cycle place.
Abrasive material piece is as the core component of mill, and the quality of its quality directly affects service life and the grinding efficiency of mill.Taking ceramic bond super-hard material mill abrasive material piece as example, the manufacturing process of traditional superhard material mill abrasive material piece is as follows: 1, according to mill size, and the size of engineered abrasives piece and arrangement mode; 2, and size block-shaped according to the abrasive material of design, utilizes different size mould the moulding mixture being mixed by abrasive material, bonding agent, filler to be suppressed one by one on press to corresponding abrasive material compact body; 3, by the abrasive material compact body suppressing at sintering kiln roasting.
There is following problem in traditional ceramics bonding agent extra hard material mill preparation technology: (1) is above mentioned, synchronously wear away for realizing mill Internal and external cycle, abrasive material piece size bonding on Internal and external cycle on same mill differs, and uses conventional method to manufacture the mould that a kind of mill needs plurality of specifications; (2) because abrasive material piece size is less, mill is made up of up to a hundred abrasive material pieces conventionally, the compacting of abrasive material piece, burns till with bonding labour intensity highly, and production efficiency is low.
In view of the foregoing, grinding materials and grinding tool industry is needed a kind of new ceramic superhard material mill abrasive material preparation method at present badly.
Summary of the invention
The object of the present invention is to provide a kind of superhard material mill abrasive material piece manufacture method, high to the manufacturing cost of superhard material mill abrasive material piece to solve, manufacture inefficient problem.
Meanwhile, the present invention also aims to provide a kind of superhard material mill manufacture method.
In order to address the above problem, superhard material mill abrasive material piece manufacture method is by the following technical solutions: superhard material mill abrasive material piece manufacture method, comprise the following steps: (1) makes abrasive material piece mother tuber, the thickness of abrasive material piece mother tuber equates with the thickness of the abrasive material piece that will manufacture, in addition, abrasive material piece mother tuber is the monoblock type abrasive material piece that can cut out at least two the above abrasive material pieces that will manufacture; (2) abrasive material piece mother tuber step (1) being made cuts and obtains the abrasive material compact body of two the above abrasive material pieces that will manufacture.
Also comprise step (3), the abrasive material compact body that step (2) is made carries out sintering and obtains the abrasive material piece that will manufacture.
Step (1) also comprises carries out sintering to abrasive material piece mother tuber.
Described abrasive material piece parent is compressing by monolithic mold.
In step (2), the cutting of abrasive material piece mother tuber is carried out with laser cutting device.
Superhard material mill manufacture method is by the following technical solutions: superhard material mill manufacture method, comprises the following steps: (1) makes abrasive material piece; (2) the abrasive material piece making is mounted on grinding disc substrate; Wherein in step (1), the making of abrasive material piece is performed such, first make abrasive material mother tuber, the thickness of abrasive material piece mother tuber equates with the thickness of the abrasive material piece that will manufacture, in addition, abrasive material piece mother tuber is the monoblock type abrasive material piece that can cut out at least two the above abrasive material pieces that will manufacture, then the abrasive material piece mother tuber making is cut and obtained the abrasive material compact body of two the above abrasive material pieces that will manufacture.
In step (1), before to the cutting of abrasive material piece mother tuber, first it is carried out to sintering.
In step (1), it is carried out sintering and obtains the abrasive material piece that will manufacture making after abrasive material compact body.
Described abrasive material piece parent is compressing by monolithic mold.
The cutting of abrasive material piece mother tuber is carried out with laser cutting device.
Because the present invention is by first manufacturing abrasive material piece parent, and then the method that abrasive material piece parent is cut is manufactured abrasive material piece, therefore, can realize the manufacture to plurality of specifications abrasive material piece by unified mould, reduce the production cost of abrasive material piece, meanwhile, adopt the mode of cutting than molded one by one mode, also can greatly improve the manufacture efficiency to abrasive material piece.The invention solves high to the manufacturing cost of superhard material mill abrasive material piece, manufacture inefficient problem.
