The five-axis machining center is a cutting method that uses the rotation of the main shaft to complete the cutting process, so that the workpiece can be completely produced in terms of shape accuracy, position accuracy, and the outer surface of the workpiece. The five-axis machining center does not simply merge the two processing methods of turning and milling into one machine tool, but uses the spindle movement of the five-axis machining center to realize the production and processing of various molds, plates, and furniture. It is in the current CNC A new cutting practice and cutting technique occurred under the condition of greater technological development.
Compared with the previous CNC machining process, the outstanding disadvantages of the five-axis machining center tools are mainly reflected in the following aspects:
(1) Reduce product manufacturing process chain and improve production efficiency. A variety of special tools can be installed, and the new tool arrangement has the advantage of reducing the tool change time of the five-axis machining center and improving the processing efficiency of the product. It can complete the entire or most of the processing procedures at one time. Thereby greatly reducing product manufacturing process time. This way, on the one hand, the production time incurred due to the change of the installation card is reduced, and the production cycle and expected time of the tooling fixture are also reduced, which can significantly improve the production efficiency.
(2) Reduce the number of clamping. The reduction in the number of loading cards prevents the accumulation of errors caused by the conversion of positioning benchmarks. At the same time, most of the current turning-milling composite processing equipment has the function of online detection, which can realize the in-position detection and accuracy control of the crux of the production process data, thereby improving the processing accuracy of the product; the high-strength integrated bed design improves the difficulty The ability of gravity processing of cutting materials; the machine is equipped with active feeding installation, which can realize active feeding to continue, and basically realize the assembly line operation of a single machine tool.
(3) Reduce the space occupied and reduce production costs. Compact and elegant design, the five-axis machining center has improved the space application method, protecting and repairing more inconveniently, so that customers can be satisfied; although the single price of the turning-milling composite processing equipment is relatively high, it is because of the reduction of the production process chain and the equipment required for the product The reduction in the number of fixtures, the space occupied by the workshop and the reduction of equipment protection costs can effectively reduce the overall fixed asset investment, production operation and management costs.
