Work with dedicated sales, design, and application engineers to solve difficult process problems, or choose your standard collet or step chuck knowing that quality and reliability comes with the Hardinge name. Experience value in longer lasting products, value in machine uptime, value in work-piece accuracy and value in your customer’s satisfaction.
Individual care goes to every workholding device at each manufacturing process, from handling the initial bar stock to polishing and laser etching. Generations of skilled-machine operators have taken part in the many critical processes of producing a hardened, precision-machined collet. Hardinge has been manufacturing workholding and industrial products for all brands of lathes, mills and grinding machines for over a century. Their process expertise, precision and accuracy provides a workholding product that is world-renowned.
A very important factor in manufacturing collets, feed fingers and pads that are long lasting and provide the performance you expect is the raw material used and the heat treat process control system to guarantee proper hardness and tempering. Collets and feed fingers are prone to breakage where the hardened area meets the tempered area. Hardinge`s heat treat processes are planned to eliminate breakage on critical design areas to provide a product that is not subject to breakage and wear. Hardinge collets are 5 to 7 points of Rockwell “C” harder than competitor’s products to provide a longer lasting product. The harder the collet, the longer the life, reducing collet changeover and downtime associated with collet changing. However, if a collet is too hard, it could be brittle and break. It is the combination of hardness, spring and spread that Hardinge has perfected over the years at their Elmira, New York facility.
