Description
Widin Live Centre — Half Tipped Dead Centre, LM-H Type, No.3 is a precision lathe accessory designed to deliver smooth, repeatable turning performance. The half-tipped center reduces bite into the workpiece, helping minimize surface marks and chatter for cleaner finishes on challenging parts. It’s available in Morse tapers No.1 through No.7, giving you flexible mounting options for a wide range of machines and setups.
With a robust LM-H design, this live centre provides stable seating in the spindle and dependable alignment across long runs. The half-tipped profile and careful geometry are engineered for durable, repeatable results in daily production or precision prototypes alike.
- Half-Tipped Design for Minimized Bite Interference: Reduces bite between the centre and the workpiece, promoting smoother starts and reducing surface marking so you can achieve cleaner finishes on sensitive parts.
- Ultra-Low Runout: Achieves runout of 0.00012"–0.0002" (0.003–0.005 mm), ensuring true rotation and concentric turning for accurate, repeatable results across multiple passes.
- Morse Taper Versatility (No.1–No.7) with LM-H Type: Fits standard Morse tapers No.1 through No.7 and uses the proven LM-H seating for reliable mounting, quick setup, and consistent alignment on a wide range of lathes.
This centre is a practical choice for engineers, machinists, and hobbyists who value dependable precision. Its combination of reduced bite, tight runout, and broad taper compatibility helps you complete jobs faster, with fewer reworks and more consistent finishes—whether you’re producing parts in batches or chasing the tight tolerances required by delicate components.
