The Steel Lathe Alignment Test Bar Mandrel is a precision tool designed to assist in the accurate alignment of a lathe's headstock and tailstock. Proper alignment is essential to eliminate taper turning, especially when machining long-length workpieces. Manufactured from high-quality steel, this test bar is precision ground to ensure straightness, rigidity, and consistent performance. The MT2 regular taper allows secure mounting in compatible lathes, making it ideal for setup, inspection, and routine maintenance tasks. With an overall length of 180 mm, this alignment mandrel provides a reliable reference for checking spindle and tailstock alignment, helping machinists achieve improved accuracy, better surface finish, and repeatable results. Suitable for professional workshops, tool rooms, and industrial machining environments.
