Hardinge Inc

Hardinge Inc. is the world's largest manufacturer of spindle tooling.

Our inventory of collets, feed fingers and other workholding devices is unsurpassed. Hardinge has--in stock--an incredibly wide variety of styles, sizes, and shapes to meet the requirements for your workholding application needs. Whether you require spindle tooling for automatic screw machines, lathes, mills, grinders, or fixtures, we are the workholding experts with the highest standards in the industry.

Hardinge collets, for example, are noted for having the best TIR (total indicator reading) in the industry. They last longer than other collets because they are the hardest collets manufactured to 62 Rockwell C standards. Our world-renown 5C and 16C collets are made from special alloy steel (the "C" stands for cataract, named for the waterfalls seen from the window of the original Hardinge factory in Chicago). Collets are heat treated and spring tempered to ensure accuracy and longer life at a low cost.

Hardinge Sure-Grip Counterbalanced 3-Jaw Power Chucks

Hardinge Sure-Grip Standard and Quick-Change Counterbalanced 3-Jaw Power Chucks are lever-operated, counter-centrifugal and dynamically balanced. This enables you to continually operate your CNC lathe at higher spindle speeds and feed rates with less concern for loss of jaw force normally associated with other manufacturer's chucks. All this is attainable at prices competitive with wedge-type chucks.

Our products are available for immediate shipment from stock in several strategic locations throughout the United States. The main office in Elmira, New York has customer representatives dedicated to taking and entering orders. Once received, your order is processed, packaged and ready to be picked up by the delivery service within twenty minutes.

Hardinge also has a select engineering group, and large manufacturing team, which custom designs and produces special workholding devices, systems, collets, feed fingers and pads manufactured to customer specifications. Our experienced engineers offer you their expertise and technical assistance in designing the workholding device that can make your tough machining jobs possible.
