Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for performing angle cutting, angle groove processing, etc. of an aluminum sash.

[0002]

2. Description of the Related Art Various processing devices are known for performing angle cutting and angle groove processing of an aluminum sash. For example, one end of the cutter support frame in the longitudinal direction is rotatably mounted on a base on which an aluminum sash is arranged, a rotary drive mechanism is attached to the rotation center of the cutter support frame, the cutter is attached to the cutter support frame, and the aluminum sash is attached. There is known a processing device that performs angle cutting and angle groove processing by rotating the cutter support frame by a predetermined angle in a state where the cutter is fixed on the base and changing the angle of the cutter with respect to the aluminum sash.

[0003]

The above-described processing apparatus has a cantilever support structure in which one end of the cutter support frame in the longitudinal direction is rotatably supported, and the rotation drive mechanism is provided at the center of rotation. When the rotational accuracy of the cutter support frame goes to the other end in the longitudinal direction, the accuracy of the cutter tends to change, the accuracy of the angle of the cutter with respect to the aluminum sash is poor, and the aluminum sash cannot be accurately cut into a predetermined angle.

Further, since the cutter supporting frame is largely deflected in the vertical direction during machining with the cutter, the precision of the groove depth is poor in the case of grooving.

Further, since the rotary drive mechanism is provided on the base and the cutter is located above the base, aluminum sash chips from the cutter enter the rotary drive mechanism and cause a failure or the like. .

Therefore, an object of the present invention is to provide a processing apparatus capable of solving the above-mentioned problems.
