Abstract
A dust collecting device for collecting cutting chips into a dust collecting container is provided. A back-flow preventing wall(s) is fixedly disposed on a flow path member defining a flow path between a machining apparatus and the dust collecting container. The back-flow preventing wall(s) is configured to decrease a cross sectional area of a flow path part defined by the flow path member in a downstream direction with respect to the flow of the air containing the cutting chips toward the dust collecting container.
Claims14
A dust collecting device for a machining apparatus, comprising:
- a dust collecting container;
- and
- at least one back-flow preventing wall fixedly disposed on a flow path member and configured to decrease a cross sectional area of a flow path part defined by the flow path member in a downstream direction with respect to the flow of air containing cutting chips toward the dust collecting container.
A back-flow preventing device disposed within a flow path member defining a part of a flow path between a machining apparatus and a dust collecting container for preventing cutting chips collected within the dust collecting container from flowing back toward the machining apparatus, comprising:
- at least one back-flow preventing wall fixedly disposed on the flow path member, so that a cross sectional area of a flow path part defined by the flow path member decreases in a downstream direction with respect to the flow of the air containing the cutting chips toward the dust collecting container.
