Description

Five axis processing machine install a Laser head}

The present invention relates to a 5-axis processing machine equipped with a laser head, and more particularly, a workbench installed in a body and driven in three axes, a head portion driven in two axes, and a laser mounted in the head portion and pivoted 180 degrees. The head is installed to smoothly weld all sides of the weldment in one work setting, and different types of laser nozzles are attached to both sides of the laser head, so that various types of laser beams can be irradiated to the weldment. The present invention relates to a five-axis processing machine equipped with a laser head which is free from welding, thereby reducing welding time and increasing the efficiency of the processing machine.

Conventional processing machines, ie machining centers, are complex machine tools integrating boring machines, milling machines, and drilling machines into three axes by linear, rotary, and spindle rotational motions. Machining work is to be performed, and when machining a sophisticated and complicated structure through such three-axis machining, it is impossible to prevent the rotation of the tool due to cutting interference, that is, the occurrence of undercut phenomenon, and thus, practical tire mold machining is impossible. It was to have significant usage problems.

On the other hand, as a solution to the problem of the machining machine (machining center) for performing the three-axis machining work, in recent years rotary table (Rotary Table) to perform the two-axis (rotation and inclination of the weld) to the above-mentioned three-axis machining center It is a situation that the mold making machine which adds and installs and performs 5-axis machining work is widely used.

Recently, small and medium vertical high-speed 5-axis processing machine has moved away from traditional areas such as aviation parts, impellers, tire molds, and propellers. It is beginning to be applied to the processing of small precision molds such as portable audio equipment. This trend is expected to expand gradually, and thus, the role of 5-axis machining machines in the existing three-axis machining area such as the mold sector is expected to be greatly increased.

Since the 5-axis machine can change the attitude of the tool, it has the advantage of being able to process deep parts even with a short tool due to the improved accessibility as a work piece. This is one of the characteristics of the 5-axis processing machine that can compensate for the shortcomings of the general high speed processing machine. This property allows the short wall of the mold with the drawing gradient to be machined. The use of short tools in small precision molds is an effective means to achieve both precision and surface finish.

However, the conventional five-axis processing machine has a vertical milling spindle is installed, there is a problem that the milling spindle can not be used for welding because only the machining.
