Live Center Turns Ultra-Small Workpieces
The live center’s small bearing head diameter and long spindle provide clearance for small workpieces, which is said to make it well-suited for high-production machine tools running light parts. The centers are available in Morse tapers and customized designs.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
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.
