Mechanical Switch: This device features a flat magnetic surfaces that remains intact when switching between ON and OFF positions. High-efficiency magnets ensure minimal residual magnetic force and precise spacing between magnetic poles. Strong Magnetic Force: Designed with a unique radial pattern, this device boosts suction power and enables the layering of magnetic forces, making it perfect for heavy-duty grinding tasks. Easy Operation: The intuitive mechanical switch allows for rapid loading and unloading of workpieces, enabling the simultaneous clamping of multiple items to enhance productivity. Fine Intervals: The circular design provides exceptional rigidity, achieving magnetic force precision down to ones micrometer with minimal variation. It also boasts strong suction, close magnetic pole spacing, and consistent magnetic force distribution. Customer Service: We prioritize our customers' shopping experiences.
