Toolholder Damps Vibration, Reducing Wear
The Tendo Platinum toolholder from Schunk is designed for durability, ease of use and precision for many milling, drilling and reaming applications.
The Tendo Platinum toolholder from Schunk is designed for durability, ease of use and precision for many milling, drilling and reaming applications. Improved brazing technology with a single-cycle brazing and hardening process gives the toolholder rigid and durable tool clamping. Hardened high-grade tool steel ensures long life.
The toolholder is designed to offer vibration damping and runout accuracy of less than 0.003 mm (0.0001") at 2.5 times clamping diameter, working with the machine spindle and the cutting tool to reduce wear and damage. The company offers direct clamping in both metric and inch sizes.
Vibration is at the heart of a variety of common problems in machining holes. Mathematical analysis is helping to bring about a better understanding of hole-making processes...including how these vibrations behave, and what steps to take to bring them under control.
Most turning centers are equipped with some helpful canned cycles. Fanuc, for example, has three simple, one-pass canned cycles (G90 for turning and boring; G92 for threading; and G94 for facing).
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
