An automated oxy-fuel thermal processing system including an oxy-fuel torch, an automated machine tool operatively coupled to the torch for moving the torch relative to a work piece, and a circuit including a voltage source or a current electrically connected to the torch and configured to be electrically connected to the work piece. The automated oxy-fuel thermal processing system may further include a processor that is operatively connected to the torch, the automated machine tool, the circuit, and the voltage source or current source, wherein the processor is configured to control the operation of the torch, the automated machine tool and the voltage source or current source, and to monitor a current or voltage in the circuit in a predefined manner.

A cutting torch guide assembly for cutting beveled openings includes a first rod that is hollow. A first sleeve is positioned around and slidably positionable on the first rod. A pin is coupled to and extends perpendicularly from the first sleeve. The pin is configured to couple to a metal substrate to define an axis of a penetration that is to be cut into the metal substrate. A second rod is positioned in and selectively extensible from the first rod. The first sleeve is positionable to select a diameter of the penetration on an opposing side of the metal substrate. The second rod is positionable relative to the first rod to select a thickness of the metal substrate. A ring coupled to the second rod is configured to insert a nozzle of a cutting torch so that the nozzle is positioned to cut a beveled penetration into the substrate.

An ambient oxygen concentrating torch has an oxygen concentrating unit disposed in operational communication with a second compressor whereby oxygen is sourced from the ambient atmosphere by Pressure Swing Adsorption and producible for pressurization and storage interior to a pressure tank. Controlled release of the stored oxygen is thereby enabled for combination with a hydrocarbon to effect combustion and production of a high-temperature flame as used in welding and cutting. Because oxygen is sourced from the ambient environment, and is continuously producible therefrom, need of separate oxygen canisters is entirely obviated.

The present inventive concept discloses design providing for the mounting of a CNC cutting machine upon a sturdily framed wheeled vehicle. The vehicular cutting machine can then be transported upon its own integral structure, to practically any jobsite. This mobility is a particular advantage to the customer at the jobsite where there is a requirement for a smaller number of precision parts in a short time during a plant or facility start-up, shutdown, or power outage. The inventive concept presents a method of use of CNC cutting machines that has not been used in the metal-cutting industry, oftentimes because of harsh road environments or the sheer difficulty of designing and building a self-powered, self-equipped CNC cutting machine. The present inventive concept negates the problems previously encountered by the prior art, and makes possible a cutting machine which is transportable and immediately available for operation upon reaching a designated website.

A separator apparatus is provided for a cutting machine which separates chips from coolant, wherein the separator includes a fluid chamber into which an airborne mixture of chips and coolant driven by an airflow enters via an entry port, the separator apparatus being configured to: sufficiently slow the speed of the airborne mixture once inside the chamber so that the chips and coolant separate out from the airflow; retain the chips and coolant released from the airborne mixture in the fluid chamber; and allow air from the airborne mixture to exit the fluid chamber via an air outlet; wherein the fluid chamber includes a chip collector which captures the chips and enables the chips to be separated and removed from the coolant in the chamber; and wherein the fluid chamber includes a coolant outlet through which coolant, from which the chips have been removed, is able to exit.
