LIVE CENTRES FACE DRIVERS

Product catalog summary

Overview: The document provides comprehensive specifications and operational guidelines for live centres and face drivers used in machining processes. It details various models, their applications, technical features, and customer benefits.

Live Centres: Live centres are categorized by design and functionality, including models like HM Pro, HMG Pro, and others. They are primarily used for counter-clamping workpieces on turning and grinding machines. Key features include wear-proof carbide inserts, high concentricity, stability due to 3-fold bearings, and lifetime lubrication.

Specifications: Each live centre type is detailed with specifications such as maximum workpiece weight, concentricity deviation, maximum speed, and dimensions. For instance, the HM Pro model supports workpiece weights up to 1800 kg with a maximum concentricity deviation of 0.005 mm.

Technical Features: Common features across models include hardened and ground bodies, 60° tip angles, and precision bearings for optimal force absorption, ensuring high cutting capacities and precision.

Customer Benefits: Benefits include maximum service life, wear resistance, and high precision. Extended centre points in some models provide better accessibility in cramped work areas.

Face Drivers: Face drivers are used for power-operated applications, with specifications including maximum workpiece weight, concentricity deviation, and speed limits.

Special Solutions: Custom solutions are available for specific machining needs, ensuring adaptability to various operational requirements.

Conclusion: RÖHM's live centres and face drivers meet high precision and durability standards, suitable for a wide range of machining applications.

Interchangeable Inserts and Components: The document details interchangeable inserts, revolving centering tapers, solid centers, and constant face drivers, emphasizing flexibility, precision, and durability.

Technical Features and Customer Benefits: Features include hardened and ground bodies, quick-change capabilities, and high precision. Benefits include a wide range of applications, quick adaptability, and high durability.

Specifications and Technical Features: Detailed specifications for constant face drivers are provided, designed for precise machining without reclamping. Key specifications include clamping circuit diameter, maximum workpiece weight, and concentricity deviation.

Customer Benefits: Benefits include turning and milling in one setup, radial backlash-free operation, and flexibility with interchangeable components.

Terms and Conditions of Sale: The document outlines RÖHM GmbH's terms of sale, including contractual obligations, pricing, payment terms, and delivery conditions.

Offer and Contractual Terms: Terms are exclusive and override contradictory terms unless agreed in writing. Offers are non-binding unless stated otherwise.

THE RIGHT LIVE CENTRE FOR EVERY APPLICATION For small and large centres For cramped work area

Open the catalog to page 8

The requirement for high cutting capacities and high working precision demands an additional support by a revolving live centre for many workpieces due to their shape and length. Thanks to their precision bearings, RÖHM live centres offer optimal force absorption and a maximum concentricity deviation of up to 0.003 mm. The centre points are maintenance-free thanks to the lifetime lubrication. ADVANTAGES AT A GLANCE Maximum concentricity and optimal force absorption thanks to proven precision bearings Special lubrication for long service life and little required maintenance Minimum interference...
