STRAIGHT SHANK PLUM DRIVE CENTER

Features:

Material: GCr15 bearing steel, T8/T10 carbon tool steel
Heat Treatment Hardness: HRC 58-62
Construction: The body and center shaft are made of alloy steel with heat and sub-zero treatment, achieving hardness of HRC 60 ± 1°.
Driving Mechanism: A driving dog is required for traditional lathe turning to prevent the workpiece from stopping. These work-driving centers feature either a 6-teeth or 8-teeth design, replacing traditional driving dogs. They support the workpiece on the end surface, allowing for easy setup and rapid machining.
Versatility: The work-driving center is also suitable for gear hobbing machines.
