技术领域technical field
本实用新型具体涉及一种超硬磨料工具。The utility model specifically relates to a superhard abrasive tool.
背景技术Background technique
目前，金属结合剂超硬磨料工具的制作方法主要有电镀法、烧结法和高温钎焊法三种。At present, the production methods of metal bond superabrasive tools mainly include electroplating, sintering and high-temperature brazing.
电镀超硬磨料工具以镍或镍合金作为镀层金属结合剂，但磨料与镀层金属之间仅存在机械镶嵌作用，镀层金属对磨料把持强度低，磨料出露高度低。烧结超硬磨料工具采用钴、铁、锡、青铜、镍合金为主要金属结合剂材料，由于磨料与金属结合剂难以形成化学结合，磨料也只是被机械包埋在金属结合剂中，金属结合剂对磨料把持强度低，工具出刃能力差。因此，这两种工具在重负荷作业时磨料会过早脱落，磨料利用率低，工具寿命短，加工效率低。Electroplated superabrasive tools use nickel or nickel alloy as the coating metal bond, but there is only a mechanical mosaic effect between the abrasive and the coating metal, the coating metal has low holding strength on the abrasive, and the exposure height of the abrasive is low. Sintered superabrasive tools use cobalt, iron, tin, bronze, and nickel alloys as the main metal bond materials. Since it is difficult to form a chemical bond between the abrasive and the metal bond, the abrasive is only mechanically embedded in the metal bond. The holding strength of the abrasive is low, and the cutting ability of the tool is poor. Therefore, the abrasives of these two tools will fall off prematurely during heavy-duty operations, resulting in low abrasive utilization, short tool life, and low processing efficiency.
为了解决上述问题，近十多年来，国内外学者研究利用钎焊法制作超硬磨料工具。钎焊超硬磨料工具，其原理是利用高温钎焊方法通过磨料、钎料和基体三者之间的化学冶金反应实现对磨料的牢固把持，使其具有加工效率高、容屑空间大、磨料利用率高、工件表面不易烧伤等显著优势。因单层钎焊超硬磨料工具制作容易，目前，材料加工领域以单层钎焊超硬磨料工具为主，但单层钎焊超硬磨料工具在使用过程中暴露出以下问题：由于钎焊金刚石锯片、磨轮、串珠的工作区域分别为锯片基体的外圆周面、磨轮与串珠基体的外圆柱面，这些面上的金刚石磨料几乎同时参加切磨削加工，几乎同时磨钝后，因与结合剂结合强度高不易脱落，与加工对象接触面积增大，切削阻力大，金刚石磨料难以破碎重新出刃，切割效率与加工质量降低，若减少工具表面的金刚石数量，虽切割力小，切割效率高，但工具寿命短。In order to solve the above problems, scholars at home and abroad have studied the use of brazing to make superabrasive tools for more than ten years. The principle of brazing superabrasive tools is to use the high temperature brazing method to achieve a firm grip on the abrasive through the chemical metallurgical reaction between the abrasive, the brazing material and the matrix, so that it has high processing efficiency, large chip space, and abrasive High utilization rate, not easy to burn the surface of the workpiece and other significant advantages. Because single-layer brazed superabrasive tools are easy to manufacture, at present, the field of material processing is dominated by single-layer brazed superabrasive tools, but the following problems are exposed during the use of single-layer brazed superabrasive tools: due to brazing The working areas of the diamond saw blade, grinding wheel, and beading are respectively the outer peripheral surface of the saw blade base, the outer cylindrical surface of the grinding wheel and the beading base, and the diamond abrasives on these surfaces participate in the cutting and grinding process almost at the same time. The bonding strength with the bonding agent is high and it is not easy to fall off, the contact area with the processing object increases, the cutting resistance is large, the diamond abrasive is difficult to break and re-extrude, the cutting efficiency and processing quality are reduced, if the number of diamonds on the surface of the tool is reduced, although the cutting force is small, the cutting efficiency High, but short tool life.
