ABSTRACT:
A thermal energy machining (“TEM”) machine is designed with interchangeable components for processing different sized parts within a single frame. The frame weldment includes a base, an upper mounting plate and intermediate mounting plates. In one embodiment, a TEM machine for processing short parts includes a ram cylinder directly secured to the base, a chamber spacer directly secured to the upper mounting plate and a thermal chamber directly secured to the chamber spacer. In another embodiment, a TEM machine for processing long parts includes a thermal chamber directly secured to the upper mounting plate, a ram spacer directly secured to the base, and a ram cylinder directly secured to the ram spacer.
