Product catalog summary

Overview: The document provides technical specifications and guidelines for Taper Collet Flange Mandrels BKDF, focusing on their clamping principles, features, configuration, and technical data.

Clamping Principle: The Taper Collet is designed to be pulled against the seating body, expanding radially over the cone of the base body. This ensures the component is centered, pressed against the backstop, and aligned flush.

Features:

Clamping diameters range from 11.9 mm to 132 mm.
High true running accuracy of ≤ 0.01 mm.
Permissible component tolerance up to IT15.
Pull-back against external backstop surface or ring provided by the customer.
Suitable for both thin-walled and solid components.
Optional hand clamping available.

Configuration: The mandrel consists of a seating body and a Taper Collet with a draw bolt. Optional configurations include Taper Collets with hexagon heads or pre-centering and a plate with a threaded bore. The clamping fixture is actuated by the draw bolt connected to the machine's power actuating unit.

Technical Data: The document includes a detailed table listing various BKDF models with specifications such as clamping range, maximum diameter change, maximum transmissible torque, and maximum actuating force. Key parameters include:

Clamping range and diameter change for each model.
Maximum transmissible torque and actuating force.
Insertion depth formula: Lemin. = K + Lf + 4 mm (Sl min.).

Ordering Information: When ordering, specify the size of the Clamping Fixture and the clamping range of the requested Taper Collet, e.g., BKDF 27-46,60-47,80.

Additional Notes: The document advises on standard clamping ranges and provides a formula for calculating minimum insertion depth based on component chamfer length and dimension K.
