ABSTRACT:
A wood working machine comprises a carriage on which a plurality of working heads are mounted in a juxtaposed relationship, and a tool magazine and an exchanging unit provided on the carriage for each of the working heads such that exchanging of a tool can be performed on the working heads independently of each other on the carriage. A dust collecting passageway is formed between a motor for a spindle of each of the working heads and a motor hood for the motor, and an additional auxiliary dust collecting passageway is formed on each of rams on which the working heads are individually held. A wide dust collecting range is thus assured.
