Electro-Permanent Rotary Chuck

Product catalog summary
Introduction
BRAILLON MAGNETICS, a pioneer in magnetic technology, developed the first Electro-Permanent magnetic chuck in 1963. The technology has since evolved, offering powerful and reliable magnetic chucks for chip removal and cylindrical grinding operations.
Key Features
  • Tool Clearance: Circular chucks with raising pole shoes provide three-side access to the workpiece.
  • Reliability: Static design without movable components ensures durability.
  • Accuracy: Electro-Permanent releases enhance accuracy and safety, eliminating the need for continuous electrical power.
  • Clamping: Homogeneous magnetic force distribution prevents workpiece distortion.
Magnetic Rotary Chucks Designs
  • Radial: Ideal for ring-shaped workpieces, maximizing magnetic flux concentration.
  • Concentric: Suitable for multiple workpiece arrangements, effective for thick and medium-sized workpieces.
  • Parallel: Best for clamping thin and small workpieces, with a small pitch parallel top plate design available for extra-thin workpieces.
Technologies
  • Compensated Electro-Permanent (EP): Uses Neodynium and Alnico magnets for high magnetic clamping force.
  • Full Demagnetization Electro-Permanent (EP): Utilizes Alnico magnets to achieve low residual magnetism after demagnetization.
  • Electro-Magnetic (EM): Maintains magnetization until power is switched off, offering high magnetic force economically.
Product Specifications
  • Variable magnetization, solid block body design, IP65 sealed.
  • Operating voltages: EP - 340VDC, EM - 110VDC, with other voltages available on request.
  • Top plate features: Brass pole separator, 8mm wear distance, Ra1.6 roughness, 2/100/m flatness and parallelism.
Optional Items
  • Quick IP65 connector, tailor-made pole shoes, embedded slip ring assembly.
  • Custom voltage, brass/aluminum/epoxy pole gaps, T-slots, segmented magnetic zones.
  • Standard slip ring assembly features: Max rotary speed 4100 RPM, spring-loaded brush holders, removable bronze-carbon brushes.

MAGNETIC ROTARY CHUCKS BRAILLON MAGNETICS invented and built the first Electro-Permanent magnetic chuck in 1963. Since then the E-P technology has evolved constantly, resulting in a range of very powerful, reliable and sturdy magnetic chucks for chip removal and cylindrical grinding operations. THE LARGEST TOOL CLEARANCE Using raising pole shoes, BRAILLON MAGNETICS circular chucks allow a 3 side access to the workpiece. Bearing rings grinding HIGH RELIABILITY Thanks to a static design without any movable components, BRAILLON MAGNETICS Circular Chucks are built to last. HIGH ACCURACY Electro-Permanent...

Electro-Permanent Rotary Chuck-3

CI RCU I TS BRAILLON MAGNETICS has become a world leader in the 3 following magnetic technologies : COMPENSATED ELECTRO-PERMANENT (EP) EP technology consists in magnetizing the chuck with a single electrical pulse. The chuck is then magnetized even if a voltage drop occur. The Compensated EP technology is a combination of Neodynium and Alnico magnets to reach the highest possible magnetic clamping force. M AGN E TI C FULL DEMAGETIZATION ELECTRO-PERMANENT (EP) EP system based technology as well, the Full Demagnetization consists in using only Alnico Magnets. The great benefit is to reach the lowest...
