Riten’s extra-light (X-Light) live center is designed to turn workpieces weighing as little as 2 ounces at speeds as fast as 8,000 rpm while holding concentricity of ±0.00005. Applications include making parts for the aerospace and medical industries as well as for small-engine components.
The shell is manufactured from low carbon steel and is case-hardened, while the spindle is manufactured from 52100 ball-bearing steel and through hardened to 60 Rc. Precision angular contact bearings are graded and matched at the factory to obtain the proper fit necessary to hold concentricity in high speed applications.

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. 


  • Successful Application Of Ceramic Inserts

    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.

  • Machining Dry Is Worth A Try

    Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.

  • Rigid Tapping--Sometimes You Need A Little Float

    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.
