Not sure which magnetic chuck fits your machine and workpiece? Send the machine type, workpiece material, size, thickness, process and holding requirement, and we will help check the suitable series.
Select the magnetic chuck series according to the workpiece material, size, thickness, machining process and required holding force. Electromagnetic, permanent magnetic and electro-permanent chucks suit different machine types and production conditions.
Rectangular electromagnetic chucks are used for holding flat ferromagnetic workpieces during surface grinding and related machining operations. They provide controllable magnetic holding force for plate-type and rectangular parts.
Fine pole rectangular electromagnetic chucks are used when smaller or thinner workpieces require more uniform magnetic holding. The fine pole design helps improve support for precision grinding and delicate parts.
Powerful rectangular electromagnetic chucks provide stronger holding force for larger or heavier workpieces. They are suitable for demanding surface grinding and machining conditions where stable magnetic clamping is required.
Circular electromagnetic chucks are used for holding round or disc-type ferromagnetic workpieces. They are commonly selected for rotary grinding and circular workholding applications.
Tool grinder electromagnetic chucks are designed for tool grinding machines and narrow workpieces. They are suitable for holding long strips, cutting tools and precision parts during grinding operations.
Electro-permanent magnetic chucks use electric activation and permanent magnetic holding. They are suitable for machining setups that require stable holding force with reduced continuous power consumption.
Permanent magnetic chucks provide manual magnetic holding without continuous power supply. They are commonly used for surface grinding, inspection and general workshop workholding.
Fine pole permanent magnetic chucks are suitable for smaller and thinner ferromagnetic parts. The fine pole structure helps improve holding stability during precision surface grinding.
Rotary pole permanent magnetic chucks allow the pole direction to be adjusted for different workpiece shapes and holding requirements. They are used when flexible magnetic positioning is needed.
Powerful circular permanent magnetic chucks provide strong holding force for round or ring-shaped workpieces. They are suitable for circular grinding and applications requiring stable magnetic support.
Single tilt fine pole permanent magnetic chucks combine fine-pole holding with one-direction angular adjustment. They are used for grinding parts that require a controlled tilt angle.
Sine permanent magnetic chucks are used for precision angle grinding. The sine mechanism allows the workpiece angle to be set accurately for inclined surfaces and angular machining.
Compound sine permanent magnetic chucks support angular adjustment in two directions. They are used for workpieces that require compound angle grinding or more complex positioning.
Tungsten steel special magnetic chucks are designed for holding tungsten steel and other small hard-metal workpieces. They help improve support stability for precision grinding applications.
Permanent magnet lifters are used for lifting and handling ferromagnetic workpieces. They are suitable for workshop handling, material transfer and loading operations.
Vacuum chucks are used for holding non-magnetic or thin flat workpieces by vacuum force. They are suitable for materials and parts that cannot be held by magnetic force.
Send the machine type, workpiece material, dimensions, thickness, machining process and holding requirement. We can help compare electromagnetic, permanent magnetic, electro-permanent, sine, lifting and vacuum solutions.
Before selecting a magnetic chuck, confirm the workpiece material, size, thickness, machining process and required holding force. Different magnetic chuck structures are designed for different machine types and workpiece forms.
Magnetic chucks are suitable for ferromagnetic materials. For non-magnetic thin plates or special materials, a vacuum chuck may be a better choice.
Small or thin parts may require fine-pole magnetic chucks, while larger or heavier workpieces may need stronger rectangular or circular magnetic chucks.
Surface grinding, rotary grinding, tool grinding, milling and lifting applications require different magnetic chuck structures.
Electromagnetic, permanent magnetic and electro-permanent chucks provide different control methods, holding forces and power requirements.
Sine, compound sine, single tilt and rotary pole magnetic chucks are used when the workpiece angle or pole direction must be adjusted.
The contact area between the workpiece and the chuck affects holding stability. For lifting or heavy workpieces, safety margin and rated load must be checked carefully.
| Type | Typical Use | Key Selection Point |
|---|---|---|
| Rectangular Electromagnetic Chuck | Surface grinding and flat ferromagnetic workpieces | Stable magnetic control for rectangular parts |
| Fine Pole Magnetic Chuck | Small parts and thin plates | Fine pole spacing improves support for delicate workpieces |
| Circular Magnetic Chuck | Round or disc-type workpieces | Use when the workpiece shape is circular or rotary |
| Permanent Magnetic Chuck | General grinding and manual workholding | No continuous power supply required during holding |
| Electro-Permanent Magnetic Chuck | Automated or energy-saving workholding | Electric activation with permanent magnetic holding |
| Sine / Tilt Magnetic Chuck | Angle grinding and inclined surfaces | Select according to required angle adjustment |
| Permanent Magnet Lifter | Lifting and handling ferromagnetic parts | Check rated load and safety factor |
| Vacuum Chuck | Non-magnetic thin plates and flat parts | Use when magnetic holding is not possible |
A magnetic chuck is used to hold ferromagnetic workpieces during grinding, milling, inspection or handling. It provides surface holding force without mechanical jaws, which is useful for flat, round or thin workpieces.
An electromagnetic chuck requires electric power during operation and allows magnetic force to be controlled electrically. A permanent magnetic chuck holds the workpiece without continuous power. An electro-permanent magnetic chuck uses electric activation but holds with permanent magnetic force after magnetization.
Fine pole magnetic chucks are suitable for small, thin or precision workpieces that need more uniform magnetic support. They are often used in precision surface grinding applications.
Standard magnetic chucks are designed for ferromagnetic materials. For non-magnetic flat workpieces, a vacuum chuck may be more suitable.
Rectangular magnetic chucks are commonly used for flat plates and rectangular parts. Circular magnetic chucks are used for round, disc-type or ring-shaped workpieces, especially in rotary grinding applications.
Please provide the machine type, workpiece material, workpiece size and thickness, machining process, contact surface, required holding force and whether the workpiece needs angle adjustment, lifting or vacuum holding.
