摘要： The present invention relates to a diamond tool and a method of manufacturing the same, wherein multiple abrasive layers are formed through a brazing or electroplating method, thereby improving the performance and service life of the tool. According to the method of the present invention, a plurality of concave portions are formed in a surface of the shank. A bonding paste is coated into the concave portions and abrasives are dispersed in the bonding paste to thereby form a lower abrasive layer. Again, a bonding material is coated on the lower abrasive layer and abrasives are dispersed in the bonding material to thereby form an upper abrasive layer. Then, a heat treatment is executed to fusion-bond the bonding material and abrasives onto the surface of the shank. Therefore, the diamond tools manufactured through a multiple brazing or electroplating method according to the invention can significantly extend the service life thereof, which has been a detrimental weakness of the conventional diamond tools having a single abrasive layer, in spite of various advantages of the brazing and electroplating methods. Furthermore, multiple abrasive layers can be formed inside the concave portions having a desired spacing, width and depth, thereby significantly improving the service life and the cutting performance of diamond tools.
摘要翻译：金刚石工具及其制造方法技术领域本发明涉及金刚石工具及其制造方法，其中通过钎焊或电镀方法形成多个研磨层，从而提高工具的性能和使用寿命。根据本发明的方法，在柄的表面上形成多个凹部。将粘合膏涂覆到凹部中，并将研磨剂分散在粘合膏中，从而形成下磨料层。再次，将粘合材料涂覆在下磨料层上，并且研磨剂分散在粘合材料中，从而形成上磨料层。然后，进行热处理，将接合材料和研磨剂熔合到柄的表面上。因此，根据本发明的通过多重钎焊或电镀方法制造的金刚石工具可以显着延长其使用寿命，这是具有单个研磨层的常规金刚石工具的有害弱点，尽管钎焊具有各种优点和电镀方法。此外，可以在具有期望的间隔，宽度和深度的凹部内形成多个研磨层，从而显着提高金刚石工具的使用寿命和切割性能。
