Title:
AUTOMATIC CIRCULAR SAW CUTTER
Document Type and Number:
Japanese Patent JP3585002
Kind Code:
B2
Abstract:

PURPOSE: To provide an automatic circular saw cutter that can perform high accuracy cutting rapidly besides having a small cutting margin.
CONSTITUTION: A cutting mechanism part 2 provided in such a way as to be reciprocated relatively to a workpiece is provided with a rotatory-driving part 3, a first and a second shaft members 91, 92 driven by the rotatory-driving part 3 and rotatably fitted with circular saw blades respectively, and a motion mechanism part 5 moving to push out the first and second shaft members toward a cutting action space so as to push out either one of the circular saw blades into the cutting action space within the same plane according to a cutting process and also to pull down the first and second shaft members. A first circular saw blade 41 and a second circular saw blade 42 thicker in blade width than the first circular saw blade 41 are respectively fitted rotatably to the first and second shaft members. In the going process of cutting, the first round saw blade 41 is pushed out into the cutting action space, and in the return process, the second circular saw blade 42 is pushed out into the cutting action space. Cutting in the going process and secondary machining in the return process are thereby performed rapidly with high accuracy. An optional rotary tool is rotatably fitted to the second shaft member 91 so as to perform optional secondary machining.
