Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine for forming a notch in a workpiece. For example, it can be used for notch processing for sash of architectural wood.

[0002]

2. Description of the Related Art Conventionally, an electric circular saw has been used for processing wood (see Japanese Patent Application Laid-Open No. 5-4201). For example,
In forming a notch for a sash in building wood, an operator puts the building wood on a work bench, marks the notch position, and then makes an incision in this notch position with an electric circular saw. , Forming a notch. However, in this method, since the operator has to move the electric circular saw while holding it by hand, the posture of the electric circular saw at the time of moving is not stable, and there is a problem in the processing accuracy of wood.

In order to solve the above problems, cutting machines have been used in recent years. The cutting machine includes, for example, a table on which the wood is placed on the upper surface, a fixing mechanism for fixing the wood to the table, and a cutter for cutting the wood by reciprocating linear motion protruding from the upper surface of the table. And a moving cutting mechanism. According to such a cutting machine, when cutting wood, first, an operator places the wood on the table in accordance with the notch position, and fixes the wood to the table by a fixing mechanism. Thereafter, the notch is formed by cutting the wood by running while rotating the cutter.

[0004]

However, in a conventional cutting machine, chips generated by cutting wood are scattered,
This has caused failure of the moving cutting means and contamination of the workplace.
