Laser machine tool having suction system

A machine for machining a workpiece or for producing a molded body, the machine comprising:

• a machine frame;
• a workpiece table and a laser processing head mounted indirectly to the machine frame via intermediate adjusting axes, the laser processing head including a powder nozzle, and being configured to emit a focused laser beam;
• a process chamber enclosing a process space and comprising a process chamber door, which is configured to open and close the process chamber, the workpiece table and the laser processing head being disposed inside the process chamber;
• a material powder container cabinet that is configured to store material powder and comprises a door that is configured to open and close the material powder container cabinet;
• and
• a suction system comprising:
• a fan configured to generate an air flow;
• a first suction apparatus including a first waste air duct that is fluidically connected to the fan, the first suction apparatus being configured to suction particles out of the process space;
• a second suction apparatus including a second waste air duct that is fluidically connected to the fan, the second suction apparatus being configured to suction particles out of the material powder container cabinet;
• and
• an air inlet and an air outlet that are fluidically connected to the first waste air duct and are arranged in the process space;
• wherein:
• one or both of the first suction apparatus and the second suction apparatus comprise a suction power controlling means for controlling a suction power thereof;
• and
• the machine is configured to machine the workpiece or produce the molded body by location-selective solidification of the material powder, to form connected regions by the focused laser beam.
