Hardinge Workholding was mentioned in the article that was released on 4/12/10 on the Today’s Machining World website, entitled “How it Works” at http://www.todaysmachiningworld.com/how-it-works-getting-a-grip/. Be sure to check it out, it’s a very helpful article on the importance of workholding in your machining application.
Precision gripping solutions for the Fastener industry
July 13, 2009
Hardinge manufactures collets for all brands of machines and adapters used in the fastener industry. They engineer precision collets to grip blind bolt fasteners, solid and blind rivets, bolts, screws, nuts, inserts and studs. A majority of these fasteners are used in the global aerospace market. Hardinge has provided over-the-shoulder gripping, solutions for non-marking and will incorporate features such as coolant flushing into the collet design. They will provide micro surface finishes and critical radii with any additional inspections that may be required for the application. Along with aerospace Hardinge supports the automotive, commercial transportation, defense and industrial markets with these products. Call 800-843-8801 or submit your questions via this blog.

Gripping bullets, gun parts and optical lenses
May 27, 2009

This push-to-close style collet and stationary collet will grip a cartridge for either trimming to length or forming of the extractor groove. The smaller double-angle Erickson-style collet grips a bullet jacket for trimming to length. Hardinge manufactures collets and super-precision CNC turning centers used for turning the bullets, trimming bullet jackets, grooving the shanks of the cartridges and crimping the cartridge to the bullet.
Micro finishes and critical radii prevent marking of the soft materials used to make bullets. Hardinge supplies off-the-shelf and custom collets for firearm, ammunition, optic and paintball gun manufacturers worldwide. Collets, step chucks, fixtures and custom assemblies hold barrels, firing pins, trigger mechanisms, optical lenses, bullet jackets and cartridges.

Synchronized Spindle Transfer
May 11, 2009Synchronization is required for spindle transfer of odd-shaped parts including hex and square stock and for round parts using live tooling on the main and sub-spindles. Without synchronized collets extra programming and cycle time are required to line up the workpiece to properly transfer the part from one spindle to the other.
In most cases (draw-in style collets) a keyway is used to align the collets when inserting it into the spindle. Synchronized collets orient the part to a specified point on the workpiece. Hex and square collets are synchronized to the center of the flat or the corner. Hardinge will provide a high tolerance of within 15′ or ¼°. Still greater tolerance can be achieved when required. Collets for specific machines such as Acme Gridley, Hydromat and other multi-spindle lathes that already have a keyway can be synchronized to the customer’s specifications.
