Highest uniform clamping force up to 140 N/cm²
Less than 5°C chuck temperature rise after 1 hour working
Mono-block housing for maximum stability
Low current with minimum power consumption
Low profile for more wheel head clearance
Versatile clamping, excellent holding on a broad range of
workpiece size
A fine-pitch electromagnetic chuck is a precision work-holding device designed to clamp thin, small, and delicate workpieces during surface grinding and light machining.
Key Characteristics & Specifications
• Fine Pole Design: Features very small gaps between magnetic poles (typically ranging from 1.5 mm to 6.5 mm), creating a shallow magnetic field depth. This prevents the magnetic flux from leaking deeply into cutting tools or distorting thin parts.
• Uniform Clamping Force: Distributes magnetic holding evenly across the top plate, reducing warpage compared to mechanical jaws.
• Jawless Accessibility: Leaves five sides of the workpiece completely unobstructed for free machining access.
• Electrical Control: Operates via a direct current (DC) supply—commonly 110V DC—controlled through a rectifier or variable unit that allows precision demagnetization and residual magnetism neutralization.
• Coolant & Water Resistance: Built with sealed or soldered top plates to withstand grinding fluids and lubricants.
Common Applications
• Surface Grinding: Holding thin steel sheets, shims, plates, and small components that would bow or slip under standard coarse-pitch chucks.
• Light Milling & EDM: Used where low magnetic penetration and high surface accuracy (such as 0.010 mm/300 mm parallelism and flatness) are required.
If you have a specific application in mind, let me know:
• What type of machine you are mounting it on (surface grinder, miller, etc.)
• The size and thickness of the workpieces you plan to hold
Fine pitch electro magnetic chuck is a type of magnetic workholding device. Can be used for surface grinder machine, tool grinding machine and electromachine etc. Able to suck magnetic conductivity materials, the suction force is well-distributed and with high processing accuracy. It’s suitable for processing small workpieces.
