Magnetic (EPM) and Vacuum Workholding Systems

Magnetic (EPM) and vacuum workholding systems are engineered to deliver maximum precision, safety, and efficiency in CNC machining, especially for complex and demanding applications. Assfalg Magnaslot electro-permanent magnetic systems provide strong, reliable clamping without continuous power consumption. The homogeneous magnetic field ensures minimal deformation and vibration-free machining, even for thin or large workpieces. Vacuum systems offer secure and surface-friendly clamping for non-magnetic materials such as aluminum, stainless steel, and plastics. Advantages in complex and demanding machining: Distortion-free clamping of thin and large workpieces Maximum accessibility for 5-axis machining Reduced vibration for superior surface finish Ability to machine multiple sides in one setup Less fixturing, faster setup times Minimal contact = maximum machining freedom Magnaslot EPM system benefits: Fail-safe clamping (no power required to hold) High and uniform clamping force Low residual magnetism Fast magnetization / demagnetization High operational safety Keywords: EPM magnetic chuck, magnaslot, magnetic clamping, vacuum table, CNC workholding, 5-axis clamping, precision machining, distortion-free clamping
