In turning operations, geometric accuracy is crucial. Conventional jaw chucks generate localized radial pressure that can deform components, particularly thin-walled workpieces, during machining. After the clamping force is released, the workpiece often springs back into a geometrically distorted shape.
Magnetic clamping solutions from US reduce this risk through low-stress, full-surface clamping. The uniform distribution of force promotes high dimensional accuracy and parallel flatness while minimizing mechanical deformation. This ensures consistent manufacturing quality across various industries—from solid discs to delicate rings.
Flexibility for Complex Workpieces
Magnetic clamping technology offers a high degree of flexibility for a wide variety of workpiece geometries and demonstrates its strengths even with demanding components. Discs, rings, or delicate workpieces can be securely held without damaging contact surfaces or obstructing the work area.
Increased Productivity Through Fast Setup
In turning operations, our magnetic clamping technology significantly reduces setup times, as the time-consuming alignment of conventional jaw chucks is eliminated. With electro-permanent systems, a short electrical pulse is sufficient for reliable activation. Since no obstructing clamping elements restricts the machining space, you benefit from optimal accessibility and can often complete the machining of components in a single setup.
Process Reliability Through Electro-Permanent Technology
Our systems offer strong holding force combined with high operational reliability. The magnetic force remains permanently active after a brief electrical pulse—even in the event of a power failure. Since no continuous current flows during operation, no internal heat is generated in the clamping device. This reduces thermal drift and ensures dimensionally accurate results even at high speeds and during long cycles. Rectangular Permanent Magnetic Table for EDM Machines
