Description
The Widin Live Centre with Spanner design is a half-tipped dead center featuring a nut-type LM-FN interface. It is built for machinists, engineers, and workshop professionals who require stable support and precise alignment during turning and finishing operations.
With Morse taper options available (No. 1 and No. 5), this center can be matched to a wide range of lathes. The LM-FN Type No.3 variant uses half-tipped geometry to minimize bite interference and deliver true runout of 0.00012" to 0.0002" (0.003–0.005 mm).
- Ultra-low runout: Achieves runout as tight as 0.00012" to 0.0002" (0.003–0.005 mm), providing precise turning with minimal deflection.
- Half-tipped design with nut-type LM-FN interface: Minimizes bite interference and ensures repeatable seating for smooth starts and improved finish quality.
- Morse taper options: Available in No. 1 and No. 5 Morse tapers, enabling versatile mounting across a wide range of machines.
