Can-Eng Furnaces International Ltd. was contracted to engineer and commission two large-capacity heat-treatment furnaces for a global producer of highly engineered metal earth-moving, construction and mining equipment. As part of this turnkey contract, Can-Eng designed and commissioned individual tempering and stress-relieving furnaces. Both systems were assembled and tested at Can-Eng’s Niagara Falls facility prior to shipment and commissioning. They are part of a major expansion by the company to satisfy increased demand for large steel castings and weldments used as part of their equipment designs.
Nonconventional machining consists of material removal by thermal or chemical methods. The most common processes that use rapid melting of material are electrical-discharge machining (EDM) and laser-beam machining (LBM).
