Abstract
The utility model is an agate processing cutting tool, and in particular relates to a split edge diamond bit for agate processing. A bit 2 is made of low temperature electroplated diamond materials. The diameter of the diamond working layer of the bit 2 which is arranged at the lower part of the round rod bitstock 1 is bigger than that of the bitstock 1. The centrosymmetric double sides of the bit 2 are equipped with a chip split slot 3, which forms a split edge. The utility model is applicable to the processing and grinding of agate ornaments and is practical and efficient.
Description
Technical field the utility model belongs to the agate process tool, particularly a kind of branch blade diamond drill bit that is used for agate processing.
The background technology agate is the ornament of people's beautify life, more than agate hardness mohs hardness 7 degree, very fast wearing and tearing of tool using steel straight peen drill bit, through improving, steel alloy structure in circular bar shape adopts low temperature electroforming diamond technology to make, and overstriking electroforming diamond on drill bit is not because this structure is divided the bits structure, chip removal preferably and cooling have reduced tool life and efficient.
The summary of the invention the purpose of this utility model is to overcome above technical deficiency, and a kind of chip removal, cooling, branch blade diamond drill bit that efficient is high are provided.
Task of the present utility model is, divides the blade diamond drill bit to constitute the drill bit two-edged in the two-sided chip dividing groove hole that has of the center, bottom of round bar drillstock symmetry.In the brill mill process of agate, because the two-sided grooved bore of drill bit symmetry is divided bits, can get rid of the chip that the processing agate produces automatically, cool off naturally, increase work efficiency, increase work efficiency more than 5 times.
Description of drawings specifies with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows branch blade diamond drill bit front view.
The left view of Fig. 2 diagrammatic sketch 1.
The vertical view of Fig. 3 diagrammatic sketch 1.
Among the figure, the 1-drillstock; The 2-drill bit; 3-chip dividing groove hole
The specific embodiment is with reference to accompanying drawing 1-3, a kind of minute blade diamond drill bit, be used for agate processing boring, drill bit 2 is made by low temperature electroforming diamond, bottom drill bit 2 diamond working layers diameters on round bar drillstock 1 are greater than the diameter of drillstock 1, and the symmetry two-sided chip dividing groove hole 3 that has in drill bit 2 centers constitutes the branch sword.
Utilize the metal of electroforming deposition the super-hard abrasive diamond to be cemented on the electroformed layer of drill bit 2, form the ultrahard diamond working lining that two-edged center symmetry has slotted eye 3, when dividing sword Buddha's warrior attendant head drill bit to bore the mill operation for the agate goods, the diamond electroformed layer and the agate goods of drill bit 2 wear away mutually, cutting and grinding, the agate stone powder that wears away is constantly discharged the boring moulding from the chip dividing groove hole 3 of drill bit 2.
Divide sword Buddha's warrior attendant head drill bit, be applicable to processing, the grinding of agate, practicality and high efficiency.
