Abstract
A laser cutting tool with protective enclosure assembly for manipulating a workpiece on a movable platen includes a frame, a top protection assembly, a middle protection shield, a bottom protection assembly and a laser torch head. The top protection assembly, middle protection assembly, and bottom protection assembly are removably mounted to the frame such that they form a cavity enclosing only substantially the laser torch head.
Claims9
A laser cutting system, comprising:
- a table configured to receive a workpiece for a cutting operation;
- a laser torch head movable in relation to the table to selectively cut the workpiece;
- and
- a protection assembly disposed about said laser torch head and defining a cavity, said cavity having an open end permitting communication between said laser torch head and said workpiece;
- wherein said protection assembly is configured so as to substantially prevent escape of light from said protection assembly other than through said open end;
- and
- wherein said protection assembly includes a curved, semi-translucent shield portion for viewing said torch head.
