Description
The Widin Live Centre - Full Tipped Dead Center, LM-A Type, No.4, is a precision lathe center designed to support workpieces with stable, consistent contact during turning. Its full-tipped point and LM-A compatibility make it a reliable choice for engineers, machinists, buyers, tradespeople, and hobbyists who value repeatable results and smooth finishes in everyday turning tasks.
Morse tapers No.1 through No.7 are available, delivering ultra-low runout that helps maintain concentricity under load. Runout values are as low as 0.00012" (0.003 mm) to 0.0002" (0.005 mm), depending on the taper, so you can trust accurate alignment across setups.
- Ultra-low runout across Morse tapers (No.1–No.7): Delivers precise concentricity to reduce chatter and improve surface finish, even at higher speeds.
- Full-tipped dead center design: Provides stable, long-wearing contact that minimizes center marks and supports consistent performance through long runs.
- LM-A Type compatibility with No.4 sizing: Quick, secure mounting on standard LM-A spindles, enabling fast setup and reliable alignment across compatible machines.
This live centre helps streamline workflows, reduces rework from misalignment, and supports repeatable, high-quality results across a range of turning applications. With its precise contact, flexible taper options, and sturdy LM-A fit, you can rely on steadier turning performance and improved overall efficiency in your shop.
