Product catalog summary

Overview: The document provides technical specifications and configurations for Flat Element Flange Mandrels (KFDF), focusing on their clamping principles, features, and configurations.

Clamping Principle: The Flat Element is pre-loaded on the seating diameter of the seating body. Clamping is achieved by elastically deforming the Flat Element with an axial actuating force, centering and aligning the component flush against the backstop.

Features:

Clamping diameters range from 120 mm to 375 mm.
High true running accuracy of ≤ 0.01 mm.
Permissible component tolerance up to IT11.
Short clamping fixture and clamping length.
Pull-back against external backstop surface or ring is possible.
Optional hand clamping available.
Rubberized slots in the Flat Element.

Configuration: The mandrel consists of a seating body, thrust bolt, spacer bushes, Flat Element, and cover. It can be attached to a machine, with the clamping fixture actuated by the thrust bolt connected to the machine's power actuating unit. Intermediate flanges and spring force actuators are detailed from page 58.

Technical Specifications: A table provides detailed specifications for various KFDF models, including clamping diameters, maximum transmissible torque, and actuating force. Key dimensions and parameters are listed for each model.

Ordering Information: When ordering, specify the size of the clamping fixture and the clamping diameter of the component, including component tolerance. An example format is provided: KFDF 120-140,47H7.

Additional Notes: The locking ring prevents loss of the pressure bolt during transport and storage and must be removed before installation.

Flat Element Flange Mandrels KFDF Features • For clamping diameters from 120 mm to 375 mm • High true running accuracy ≤ 0,01 mm • Permissible component tolerance up to IT11 • Very short clamping fixture length • Short clamping length • Pull-back against external backstop surface or external backstop ring by the customer • Hand clamping optional possible • Rubberized slots in the Flat Element Seating body Backstop ring (by customer) Thrust bolt The Flat Element Flange Mandrel consists of a seating body, a thrust bolt, a set of spacer bushes, a Flat Element and a cover. An assembly for hand clamping is optionally available. The Flat Element Flange Mandrel is attached with the seating body to the machine. The Clamping Fixture is actuated by the thrust bolt, which is connected to the machine power actuating unit. Spacer bush Flat Element Cover Intermediate Flanges and Spring Force Actuators are shown starting on page 58. Clamping principle The Flat Element sits pre-loaded on the seating diameter of the seating body. For clamping, the Flat Element is elastically deformed by an axial actuating force. The component is centred, pressed against the backstop and aligned flush. Key: Axial actuating force Radial clamping force Axial pull-back
