D1 Series Back Plate

Product Description

The ZITHER/BONET D1 Series Back Plates are precision-engineered adapters designed to provide a secure and accurate mounting interface between a lathe's D1 Taper Nose Spindle and a chuck or other workholding device. Both brands are well-known Indian manufacturers of machine tool accessories, and their products are built to a common standard to ensure interchangeability and reliable performance.

Key Features and Shared Standards

• Standard D1 Cam-Lock Design: Both Zither and Bonet manufacture their back plates to conform precisely to the American Standard D1 cam-lock system. This design utilizes a tapered bore and cam-lock pins that fit into the lathe's spindle, providing a powerful, rigid, and repeatable mounting that resists centrifugal force and heavy cutting loads.

• Precision Machining: Both manufacturers ensure that their back plates are machined to high-quality standards. The tapered bore and the mounting face are precision-ground to guarantee superior concentricity and minimal runout, which is essential for accurate turning operations.

• Durable Materials: Both brands use robust materials for their back plates. They are typically made from high-grade cast iron or steel, which provides the necessary rigidity and stability to handle a wide range of turning speeds and cutting pressures without any vibration.

• Compatibility: Because they are manufactured to the same D1 standard, both the Zither and Bonet back plates are compatible with any D1-mount lathe and can accept any chuck that has a corresponding mounting bolt-hole pattern, whether it's from their own brand or another manufacturer.

• Quick Changeover: The cam-lock system on the D1 back plate allows for a fast and efficient changeover of chucks and other workholding accessories, making both brands suitable for production environments where time is a critical factor.
