A combined mechanical machining process and combined mechanical processing apparatus

摘要

Present invention makes it possible, by a simple and cost-effective combined mechanical processing device and the thermal cutting of a mechanical machining of an original plate and comprises a hole of the cutting process, a finishing operation and a process for cutting an outer periphery. At the hole cutting edge process is under a machining allowance with respect to the finished size of the hole, a hole formed in the original plate. During the finishing operation, in the hole which, due to the hole cutting edge process has been produced, a cutting tool is introduced, and the machining of the thermally cut end face of the cutting tool is guided on the inner circumference of the hole, in order to the hole to be machined to the finished size. In the process for cutting the outer periphery, the outer periphery of the blank element separated by the thermal cutting of the cutting element from the original plate out of it.
