Lucifer Furnaces, Inc. recently supplied a fifth tempering oven to Accu Trak Tool Corp., a leading manufacturer of precision knurling wheels and holders. Accu Trak uses Lucifer Furnaces’ forced air recirculating furnaces (Model 42-K24x, with a chamber size of 12 x 12 x 24 in.) to heat treat its tool parts. These ovens feature a stainless steel fan assembly to recirculate the air flow, providing uniform temperatures in the work area. Models also include multilayered lightweight firebrick insulation, a stainless liner, and a circular chart pen recorder to provide a printout of the furnace heat cycles. In addition, each oven is equipped with a programmed controller to heat and cool the furnace, which also activates an event relay to automatically open the door via an air cylinder, eliminating the need for an operator. Accu Trac’s tempering demands involve several cycles of heating and cooling, so the automatic controls and door system speeds up production time, enabling the company to provide quick turnaround service for its customers.
