The invention relates to a composite processing machine integrating cutting and electrical discharge machining, and particularly to a composite processing machine integrating cutting and electrical discharge machining.

According to the mold manufacturing, basically, the high-speed cutting center machine is used to cut the shape of the cavity on the mold, and then the mold is placed in the electrical discharge machine for electrical discharge machining. The electrical discharge machining can process the odd-shaped surface that the high-speed cutting machine cannot produce. And refine the cavity to the specified size.

However, most of the current processing machines can only perform one type of processing. For example, the high-speed cutting center machine only has the cutting function, and the EDM machine has only the function of EDM; it has little effect on small molds; but For large-scale molds (such as bumpers, lights), molds must be hung through the machine, and mold position correction must be performed each time the machine is used. Large-scale molds are more complicated and time-consuming to calibrate.

Those structures that can achieve the above-mentioned objectives include: a cutting center machine whose structure is basically the same as that currently used in the market, and the difference is that a first mounting portion and a first mounting portion are provided on a Z-axis slide table and A second mounting portion, which is used to install a cutting module, and the second mounting portion is used to install an oil injection type electrical discharge machining device, so that the present invention can perform cutting or electrical discharge machining according to a user's programming design. In this way, if a large mold does not need to disassemble, move and recalibrate the mold as in conventional technology, it can save processing time and improve the profit of the industry.

Through the above structure, the effects that the present invention can provide are briefly described as follows: 1.
