A machining apparatus includes a light source () for generating light energy, an optical system () for guiding the generated light energy to a joint position of a workpiece, a table () on which the workpiece is mounted, and a heating device () provided at the table for heating the workpiece. The machining apparatus, a machining method and production equipment using the machining apparatus allow the workpiece to be locally heated fast, which is applicable to soldering or the like.

Light energy processing device and method

A lens contamination preventive device comprises a gas jetting device for jetting out gas and a gas suction device for suctioning gas which are disposed to face each other with respect to an optical axis of light emitted through a lens. The gas jetting device and the gas suction device are disposed so as to form a layer of gas jet stream in the vicinity of a surface of the lens. The gas jetting device has a gas jetting port, a width of which is greater than a diameter of the lens. The gas suction device has a rate of suction greater than a rate of jet from the gas jetting device.
