Shank Holders Offer Locational Accuracy ±2 Microns
Kyocera Precision Tools has introduced a line of polygon taper shank holders for high-rigidity and high-precision machining. The KPC series features several holder styles for turning, grooving, cutoff and threading applications.
The special polygon taper design provides dual contact between the taper and the flange face along with an even distribution between three faces on the sides of the flange. The design is said to create a rigid body with locational accuracy within ±2 microns.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
A tooling system consisting of interchangeable cutting units and standardized locking units has a lot to offer users of CNC machines, whether for turning, milling, or both on a turn mill. These guidelines will help you think clearly about how modular, quick-change tooling can benefit your shop.
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further. Proper application, however, requires attention to their limitations as well as their benefits.
