Development and characteristics of bonding tool
Release time:2011.08.10 News source:Yuhuan Kaiyin Tools Factory Broach Browsing number:
 
  The structure type is the impact tool cutting tool and machining quality is one important factor. The most commonly used tools are integral structure type, welding, mechanical clamping style, cutting force clamping style and so on. Although these tools have long-term structural type of production applications mature, but the face of increasingly complex processing requirements, each structure type is still in varying degrees, their shortcomings and inadequacies. With the development of material science, high-performance, high hardness, difficult to process materials are constantly used in mechanical parts, these parts of the blade material processing and tool structure also made new demands. Bonding-type tool as a traditional tool structure type is an important supplement has been developed. Back in the early 1960s, some developed countries to address the problem of high hardness cutting materials, they begin to test and use the adhesive type tool. Was due to the limited level of technological development for the type of adhesive bonding tool failure (which was mainly the use of organic binder), limitations, so the bonding structure can only be used in less heat, cooling conditions are good tool (such as broaches, reamers, drill bits, shaper cutters, etc.). The early 1960s, with the advent of ceramic blade, the domestic use of phosphate has been copper oxide ceramic blade bonding tests, but more brittle adhesive resin, linear expansion coefficient, structure type to obtain satisfactory results without unreasonable . However, the temperature in the cutting speed and cutting the lower set of structure drill, milling cutter bond lengthening and the application of adhesive to achieve good results. With polyurethane and silicone adhesives appear adhesive greatly improved heat resistance (up to 500 ~ 600 ℃), so that the bonding tool technology has been rapid development and wide application, is now available suitable for high cutting speed, heat large variety of turning tools and other tools. Bonding tool has the following characteristics: ① simple manufacturing process, lower manufacturing costs; ②) low curing temperature bonding process (<250 ℃), does not reduce the original mechanical properties of tool materials; ③ 1.5 tools can improve the working life ~ 3 times; ④ poor performance can be applied to some of the welding tool materials (such as cubic boron nitride, diamond, ceramic, etc.); ⑤ variety and adhesive bonding methods directly affect the bonding process tool performance.
