Abstract

PLESSEY Aerospace at Titchfield, Hants has installed a Compact 100 vacuum furnace from Cambridge-based suppliers Torvac. The furnace has just completed the warranty year in operation on a wide range of heat treatments, brazing and degassing applications. The work is generally carried out to the full rigors of aerospace standards including mSR 953, CAA DAI/7591/65 and STAN 05/21. Typical of the jobbing work is the vacuum hardening of bevel steel supplier to ensure repeatability of furnace at the rate of 100 cycles or more gear box components which Plessey results. per month and continually finds new manufacture for the AV8B engines used Plessey is currently running the new jobs for it due to the furnace's flexibility in the Harrier jump jet. and microprocessor control. Parts, prev­ The Compact 100 is only the latest in iously rejected by excessive grinding, a series of furnaces supplied in a can now be retreated since they recover working relationship between Torvac well when rehardened and tempered. and Plessey which dates back almost 30 Successful exploitation of the tech­ years.
