Abstract
The utility model discloses a novel diamond wire saw, which comprises a metal wire base body and diamond abrasive grains, a side grain is arranged on the metal wire base body along the length direction, and the diamond abrasive grains are fixed on the side grain by means of braze welding. The utility model can realize the single ended spread of the diamond abrasive grains on the metal wire base body through the side grain, thus acquiring rather narrow saw sawn joints, and the workpiece can be processed accurately in a greater degree. The braze welding empowers the metal wire base body with high holding force to the diamond abrasive grains, the exposing degree of the diamond abrasive grains is high, the service life of the wire saw is extended, and the processing efficiency of the wire saw can be improved obviously.
Description
Technical field
The utility model relates to the hard brittle material manufacture field, is applicable to cut-out, jacking and the profiled holes Surface Machining of crisp and hard materials such as agate, jade, marble, granite, glass, pottery, monocrystalline silicon.
Background technology
Diamond wire saw is a kind of hard brittle material cutting equipment fast-developing over past ten years, according to the motion mode and the machine tool structure of silk saw, can be divided into reciprocating type and unidirectional silk saw, according to the abrasive particle user mode of silk saw, can be divided into free abrasive and fixed grain silk saw.Free abrasive silk saw, because the high loss of abrasive particle and base slurry (being collectively referred to as defibrination), and defibrination is to the restriction of the factors such as pollution of environment, its giving priority to real needs status is replaced by fixed grain silk saw gradually.Fixed grain silk saw has that joint-cutting is narrower, cost depletions is low and the advantage little to ambient influnence.Fixed grain silk saw mainly contains abrasive particle roll-down type and electrodeposition-type two classes, and wherein abrasive particle roll-down type silk saw embeds diamond abrasive grain in the silk saw matrix by the roll extrusion mode, can reduce silk saw matrix strength like this, uses uncommon; Electrodeposition-type silk saw is owing to diamond abrasive grain needs to be cemented on the metal wire base by the mode of electroplating, diamond abrasive grain just mechanically is embedded between coating and the metal wire base, therefore the coat of metal is little to the hold of diamond abrasive grain, in addition, because coating is thick, the exposed degree of diamond abrasive grain is low, and chip space is less, just cause the service life of silk saw shorter, and working (machining) efficiency is lower.And existing diamond wire saw, the cross section of its metal wire base is generally circle, because circle does not possess directionality, add man-hour, diamond abrasive grain can only complete cycle be arranged and can't single ender in metal wire base, need precision machined workpiece for some, just can produce because of the narrow inadequately situation that can't use of saw kerf.
The utility model content
The purpose of this utility model provides a kind of long service life, working (machining) efficiency height and the narrower diamond jigsaw of saw kerf.
The technical solution of the utility model is such: diamond jigsaw, comprise metal wire base and diamond abrasive grain, and its length direction of above-mentioned metal wire base upper edge is provided with a side grain, and above-mentioned diamond abrasive grain is consolidated on this side grain by brazing mode.
The cross section of above-mentioned metal wire base is square, and above-mentioned diamond abrasive grain is brazed on the face of this square metal silk matrix.
The cross section of above-mentioned metal wire base is trapezoidal, and above-mentioned diamond abrasive grain is brazed on the bottom surface of this trapezoidal metal wire base.
The cross section of above-mentioned metal wire base is arc, and above-mentioned diamond abrasive grain is brazed on the side grain at string place of this arc metal wire base.
After adopting such scheme, diamond jigsaw of the present utility model, its length direction is provided with a side grain in the metal wire base upper edge, diamond abrasive grain is consolidated in this side grain by brazing mode, like this, just can realize the single ender of diamond abrasive grain, thereby obtain narrower saw kerf, can carry out accurate more processing workpiece.And soldering makes the hold height of metal wire base to diamond abrasive grain, and the exposed degree of diamond abrasive grain is high, and the service life of a saw is long and can significantly improve the working (machining) efficiency that silk is sawed.
