New Honing Process Produces High-Precision in Manufacturing

Single Stroke Honing from Sunnen is a single-pass process that sizes and finishes a bore with a series of progressively larger superabrasive tools adjusted to a pre-set diameter. Single Stroke Honing tools rotate while passing through the bore one time and then withdrawing. The machine's servo-controlled stroking system provides flexibility with adjustable speed and various feed profiles, such as pecking, short stroke, dwell, etc. Column feed and spindle speed can be varied throughout a cycle using the machine control. 
Developed in Europe by Sunnen Products Company, the Single Stroke Honing® process for cast-iron hydraulic valve bodies produces less than 2 µm cylindricity in bores, achieving almost 200 percent more precision than previously possible.

Medical Machining: Machine Tools

The F-Series vertical machining center from Makino provides stiffness and rigidity for chatter-free cutting, agility for high-speed /hard-milling and accuracies for tight tolerance blends and matches typical of complex, 3D contoured geometry associated with medical production.
Take a closer look at some of the newest equipment that can help contract manufacturers meet the machining, micro machining, and laser processing demands for smaller and more complex surgical implants, orthotic devices and medical instruments that are being made from newer materials – and still hold their costs down.

Radius Internal Cylindrical Grinding of Complex Medical Parts and Implants

The Studer S141 radius internal cylindrical grinding machine from United Grinding is well suited for producing several tapers greater than 20 deg to 90 deg in a single clamping on complex workpieces made of extra-hard materials such as industrial ceramic, sapphire and tungsten carbide that is used in medical technology, as well as in the manufacture of human implants for shoulders, knees and hips from ceramic and titanium.
Studer S121, S131 and S141 internal cylindrical grinding machines from United Grinding extend part production capabilities by offering more advanced technology, a new dressing concept and larger size machine to handle a broader range of workpieces.
