Product Description
The ZITHER/BONET L1 Series Back Plate is a precision adapter manufactured by Zither Machine Tools Industries, designed to connect a lathe chuck or other work holding device to an L1 Taper Nose Spindle. Known for their quality and accuracy, Zither's back plates ensure a stable and concentric mounting for demanding turning operations.
Key Features
-
Conformity to L1 Spindle Standard: The back plate is engineered to precisely fit the L1 Taper Nose Spindle, a popular standard known for its quick-change cam-lock system. The tapered bore and dedicated holes for the cam-lock pins ensure a secure, rigid, and repeatable mounting.
-
Precision Machining: ZITHER/BONET back plates are precision-machined to very tight tolerances. The face and mounting surfaces are ground to ensure superior flatness and runout accuracy, which is crucial for maintaining the concentricity of the mounted chuck.
-
Durable Materials: These back plates are typically made from high-quality cast iron or steel. The material choice ensures a rigid connection that can withstand the high clamping forces and rotational speeds common in turning applications without any deformation or vibration.
-
Versatility: Zither's / BONET'S back plates are designed with a universal bolt-hole pattern, allowing them to accept various types of chucks, including three-jaw, four-jaw, and faceplates, from BONET'Sand other brands that conform to international standards.
