The primary advantage of a Magna-Vise is its ability to hold non-ferrous (non-magnetic) materials—such as aluminum, stainless steel, copper, or plastics—securely on a standard magnetic chuck. How it Works: A Magna-Vise set consists of two precision strips. When placed on a magnetized chuck, the magnetic flux holds the blocks themselves firmly to the table. The blocks are designed with a "pinching" or mechanical clamping mechanism on the interior. When you place a non-magnetic workpiece between the blocks and tighten them, you achieve powerful mechanical clamping without using traditional clamps that obstruct the work area. In short, the magnetic chuck holds the vise, and the vise mechanically holds the non-magnetic part. This combination provides a rigid setup for grinding, light milling, and inspection, while leaving the top and sides of the part open for machining. Need a visual?

The primary decision point is a common industrial challenge: securing a non-magnetic material on a machine that uses a magnetic workholding base. You Should Choose Magna-Vises if: Your Material is Non-Magnetic: Your workpiece is made of non-ferrous metals (like aluminum, brass, 300-series stainless steel) or non-metals (like hard plastic). You Are Using a Magnetic Chuck: You are set up on a machine (grinder, mill, etc.) that uses an electromagnetic or permanent magnetic chuck as its base. You Need High Precision Squaring: You need to machine multiple sides to a high degree of squareness and parallelism without the risk of clamping distortion. You Need Open Access: You require maximum work surface access without the obstruction of straps, clamps, or external fixturing. You Should Consider an Alternative if: Your Part is Magnetic: If the workpiece is steel or iron, use the magnetic chuck directly. Your Production Volume is High: If you have high-volume, repetitive grinding or milling of non-magnetic materials, our Vacuum Workholding Solutions often provide faster and simpler loading/unloading cycles than setting up a Magna-Vise.
