A thermal energy method (TEM) machine for deburring and deflashing work pieces, the TEM machine having an explosion load bearing frame. The frame comprises spaced apart coparallel first and second frame walls and a lateral structural member spacing apart the first and second frame walls. The top portion of the TEM combustion chamber is supported by the lateral structural member. The first and second frame walls are adapted to support a vertical displacement means. The first and second frame walls, the lateral structural member, and the vertical displacement means cooperate to contain vertically-directed explosion forces exerted upon the combustion chamber during the operation of the combustion chamber. Methods for deburring and/or deflashing using such TEM machines are also disclosed.

Framed TEM machine and method of operating same

A loader assembly for a TEM machine having a retractable arm that is moveable between a retracted position and an extended position. A hoop portion of the retractable arm also moves between the retracted position and the extended position. A lower closure for holding a part to be processed in the TEM machine is removably positioned in the hoop portion. A ram piston of the TEM machine is movable between a load position and a process position. When the ram piston moves from a load position to a process position the ram piston contacts the lower closure and extends through the hoop of the retractable arm to move the lower closure to the process position. A thermal chamber receives the lower closure when the ram piston moves to the process position.

Method and loader apparatus for TEM machine work chamber device

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.
