Abstract
An insulated slag collection bed for a laser-equipped machine tool. The bed substantially insulates the machine tool base from thermal damage due to the laser beam of the machine tool. Typically the laser beam in a machine tool will have significant energy density in planes below the workpiece, and in some conditions the energy density will be sufficient to damage the machine base. The present invention protects the machine base by providing a slag collection bed which serves as a shield to absorb remnant laser energy which would otherwise strike the machine base. The shield is thermally insulated from the machine base so as to protect the machine base from the temperature rise in the shield resulting from absorbing the remnant laser energy. If, over time the shield is damaged or worn, means are provided for ready replacement of both the shield and the insulation.
