Workholding Solutions for Brake Disc Clamping

Emuge Corp., a manufacturer of taps, thread mills, toolholders, clamping devices and other rotary cutting tools, offers precision workholding solutions for the clamping of brake discs, where high accuracy and repeatability are requirements in the manufacturing process.

To guarantee the highly precise manufacture of brake discs, EMUGE designed a system of mandrel and chuck clamping. The brake discs can be completely finished, including drilling operations, in three set-ups. At the heart of the clamping solution, Emuge developed a modular quick-change system for internal and external clamping. For high productivity within a size range, only the clamping element and the workpiece end stop need exchanging. When changing from internal to external clamping, the complete clamping head is exchanged over a quick-change mechanism without releasing the draw bar connection in the spindle.

Emuge's System SG or System SZ can be used in the design of the brake disc clamping system. System SG features an expanding-bush design which has a large surface area contact with the workpiece providing a clamping solution which is very rigid, accurate and repeatable. "For workpieces that have a short clamping base or for diameters with a very large tolerance, System SZ is a good choice," said a company spokesperson.

In both the SG and SZ systems, applying an axial force results in an even radial expansion of the clamping element, and at the same time, an axial movement occurs so the workpiece is both clamped and pulled against the end stop for added rigidity.
