With the development of industrial technology, the requirements of material properties (such as strength, hardness, heat resistance, abrasion resistance, tensile strength, compressive strength, etc.) for the important parts in some fields are also increasing, cause the applications of hard-cutting materials is more and more popular and given the new challenge for the machinability of subsequent mechanical manufacturing.
At present, the common hard-cutting materials are:
In order to meet the requirements of hard-cutting material in machining performance, machining efficiency and machining accuracy, Beijing Jingdiao Group has been focus on the machining technology of the hard material and specialty materials as the research direction, at the same time made a lot of tests and proposed a mature and reliable solution.
① Powerful precision machining capability meet the machining needs of micro and small parts
Some micro and small parts of medical, biological, electronic industries are mostly used hard-cutting material, not only have large material removal amount, also have a high machining effect in the product details.Precision machining capability provides effective guarantee for the machining of this kind of pats.
② Varieties of machining technology with milling, drilling, grinding Suitable for more products fields
Jingdiao high speed machining center can not only for milling and drilling machining, but also have the ability of grinding machining and formed a mature grinding process in a long time machining practice. Beijing Jingdiao has proposed a complete solution for some hard-cutting materials which is not suitable for milling.
③ Professional CAD/CAM software support Provide perfect process support
Beijing Jingdiao CAD/CAM software has a variety of machining strategies and tool path optimization method to provide process support for hard-cutting materials.
(1)Diversification of feeding/relieving way: CAM tool path editing module provides a variety of feeding/relieving ways, such as straight line connection, arc internal tangency, arc tangency and a series of ways to ensure machining stability and reduce the feeding/relieving cutter marks.
(2)The sharp deceleration ensures the machining quality: reduce the depth of cut of profile sharp corner in rough machining, and machine vibration with high-speed machining in the finish machining, thus extending the life of cutting tools, meanwhile improving the surface machining quality of workpiece.
(3)Perfect grinding adjustment function: the software support grinding machining, triangle wave, sine wave, trapezoidal wave and various fluctuation types can be created to ensure that the cutting edge of grinding head is made full use of and improve the usage of grinding head. Intelligent cone wave function can accord to the angel of grinding head, automatically generate the appropriate tool path and reduce the operation difficulty for users.
(4)Abundant of tool path editing functions: support path node editing, sorting, interrupting and other functions, and can be carried out the path of rotation, translation, array and other operations, to provide a free and quick way to adjust the machining orders for users.
④ Powerful project management ability of the CNC system Ensure the stability of machining
Beijing Jingdiao independently developed JD 50 CNC system is a flexible and efficient open platform with a strong cutting tools management and compensation, at the same time support the macro variables programming, PLC access and on-machine inspection system which can efficiently carry out adaptive machining for hard-cutting materials. System control resolution can achieve 0.1μm, effectively improve the surface machining effect of workpiece and guarantee the product machining quality.
⑤ Mature multi-axis machining technology Effectively reduce the difficulty of machining
Application of multi-axis machining can carry out parts machining at the most suitable angle, effectively reduce the length of clearance, improve the cutting tool life, machining quality and machining efficiency. Multi-parts machining for one-time clamping can reduce the positioning errors caused by multi-clamping, meanwhile the machining accuracy and workpiece surface quality can be improved by creating a series of directional working plane.
⑥ Professional technical team support Meet customer needs in time
Beijing Jingdiao Group has established a perfect engineering verification system throughout the country, and invested a large amount of funds for technology application research every year which ensures that the most optimized machining solution is provide for customers.
