Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a combined processing machine, and more particularly to a combined processing machine that performs drilling and thermal cutting.
[0002]
[Prior art]
Conventionally, laser and plasma technologies have become commonplace and have demonstrated their power in contour cutting. However, small-diameter drilling accuracy is poor and thermal processing is sometimes performed, so that drilling of drill joints is not permitted in the standard method. Therefore, the combination of laser, plasma, or gas cutting and drilling is attracting attention.
[0003]
As a compound machine for drilling and thermal cutting, a material fixed type and a processing head moving type compound machine is generally used.
