Collets

Huot says its new Angled Platform makes an excellent addition to a machine cell and will provide value for decades.

Huot's new TriScoot is constructed of sturdy 16-gauge steel with three flat shelves for maximum capacity.

The DD100 high-speed, direct-drive Super-Precision Rotary Table manufactured by Hardinge Inc. is a high-speed parts positioner with +/1 3 arc-sec accuracy and 4 arc-sec repeatability.

You've probably heard the term "vulcanized collet" and may have wondered what it means exactly. Vulcanization was named after the Roman God of Fire, Vulcan, and, yes, the injection molding process at Hardinge does involve heat.

"Back in 2008, Hardinge introduced a low-profile rotary table as a standard, no-frills unit to compete against other 210mm tables on the market," states Al Comstock, Rotary Product Manager at Hardinge Inc. "Now, by customer demand, we've redesigned the model to include the infamous Hardinge collet-ready 16C spindle that provides the high-precision gripping options for which Hardinge is known. We've also extended the spindle nose for additional tooling clearance."

A high quality collet is desirable when it comes to precision machining of small parts for the medical and aerospace industries. For a quality part that meets high-precision specifications, you need a burr-free collet with guaranteed concentricity. This collet would be finish ground to provide a smooth and concentric gripping area (order hole) for the bar stock or work piece. Hardinge Swiss-style collets meet all of these requirements.

If you've been using fixtures to grip parts on your rotary device, you already know how much operator intervention is required for setting up, clamping and locating the part, and changing from one job to another. And let's not forget about the design time and machining involved to produce the fixture itself. All of this accumulated time lengthens the production time and increases the cost of the part. Are there any other alternatives? Yes, collet-ready spindle rotary tables and indexers, manufactured by Hardinge accept a wide variety of standard tooling to grip parts of various shapes and sizes so that you can output more parts per hour at a lower cost per part.

Expanding collets and between center arbors (mandrels) grip the internal diameter of a part for turning, milling, grinding, assembly, inspection and automation applications. Hardinge Workholding Div.'s Sure-Grip Expanding Collet Systems have design features that provide durability for long production runs with superior surface finishes and fast collet changeover from the front.

What tooling does a multi-spindle automatic, a CNC lathe and a vertical machining center have in common? The answer is S-pads.
