MAGNETIC CHUCKS & CLAMPING SOLUTIONS
Clamping in seconds → drastically reduced setup times for higher output
Unobstructed access → 100% clearance for machining without interference from clamping devices
Absolute stability → secure hold without slipping for maximum process reliability
Minimal operating costs → high energy savings thanks to smart magnetic technology
Increased productivity → Premium quality engineered for higher throughput Circular Electro-permanent Magnetic Chuck
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. Circular Permanent Magnetic Chuck with Parallel Poles
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. Micropitch Poles Circular Permanent Magnetic Chucks for Turning
Flexibility for Complex Workpieces Permanent Magnet Magnetic Chuck Circular Parallel Pole for Turning & Grinding
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. Round Permanent Magnet Chuck with Micropitch Poles
Increased Productivity Through Fast Setup Permanent Round Parallel Poles Magnetic Chuck
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 Circle Permanent Magnetic Clamping with Parallel Poles
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
