Abstract
A cutting machine includes a suction duct that is movable with a cutting head of the cutting machine, using a common drive. The suction duct is disposed beneath the workpiece support and coupled to the motion unit supporting the cutting head so that it moves with the motion unit while an opening of the suction duct remains positioned below the cutting head during a cutting operation. The suction duct removes cutting debris and dust, and protects underlying machine components from beam damage.
Claims20
A cutting machine comprising:
- a workpiece support;
- a motion unit having an associated drive;
- a cutting head mounted on the motion unit above the workpiece support and configured to deliver a cutting beam to process a workpiece supported on the workpiece support;
- and
- a suction duct disposed beneath the workpiece support and coupled to the motion unit so that it moves with the motion unit while an opening of the suction duct remains positioned below the cutting head during a cutting operation, wherein the suction duct comprises a shaft configured to absorb energy from the cutting beam when the cutting head is in operation and wherein the shaft is pivotable to open a discharge chute connected to the shaft.
