Operational Safety & Maintenance Guidelines
- Always verify mechanical switch position before initiating spindle rotation or coolant flow
- Clean magnetic face with non-abrasive cloth to prevent debris from reducing holding force
- Inspect pole segments periodically for wear, burrs, or corrosion that may affect contact
- Store unused chucks with switch in OFF position to prevent accidental workpiece attraction
- Apply light machine oil to moving switch components to ensure smooth mechanical operation
- Follow standard lifting protocols when handling larger diameter units to prevent injury
Model Range & Dimensional Coverage
- Available in five standard diameters to match specific machine table configurations
- Size options include 200mm, 250mm, 300mm, 375mm, and 400mm for flexible integration
- Consistent 65mm thickness ensures compatibility with standard chuck mounting interfaces
- Each diameter variant maintains identical radial pole layout for uniform holding characteristics
- Standardized dimensions simplify spare part inventory and cross-reference management
- Factory-calibrated magnetic output guarantees reliable performance across all size options
Industrial Workholding Applications
- Turning and boring of rings, discs, flanges, and bearing components on lathes
- Precision face grinding and internal or external diameter grinding of circular tools
- Concentric workholding for rings and pipe components where parallel poles fail
- High-accuracy rotary inspection, balancing, and centering operations in toolrooms
- Ideal for heavy cutting forces that demand stable, vibration-resistant clamping
- Supports continuous production runs requiring rapid part changeover and repeat accuracy
Magnetic Field Performance & Pole Configuration
- Radial pole configuration delivers concentric gripping force for circular components
- Magnetic flux lines converge radially – preventing workpiece shifting during machining
- Even field distribution reduces localized stress on delicate or thin-walled parts
- Permanent magnet design requires zero electrical power for continuous holding force
- Quick engagement and disengagement streamline part loading and unloading workflows
- Consistent magnetic output maintains accuracy across repeated machining operations
Core Design & Operating Mechanism
- Crystal AA-159 series features a mechanical ON/OFF switch for independent clamping security
- Manual operation eliminates heat dissipation concerns during extended machining cycles
- Rigid circular body provides stable mounting for rotational grinding and heavy turning
- Star-pattern magnetic fields project maximum holding power evenly toward the center
- Segmented radial geometry maximizes contact area on ring-shaped workpieces
- Compatible with model variations ranging from AA-15916 to AA-15920 for diverse shop needs
- Uniform 65mm height standardizes setup across the entire product family
More questions buyers ask
What is a round permanent magnetic chuck?
A round permanent magnetic chuck is a workholding device that uses permanent magnets to secure ferromagnetic workpieces for machining operations like grinding, turning, and milling. The 'round' shape makes it ideal for cylindrical or disc-shaped parts.
How does a permanent magnetic chuck work?
It uses a system of powerful permanent magnets that can be turned 'on' or 'off' by rotating a handle or key. In the 'on' position, the magnetic field is directed through the top plate to hold the workpiece. In the 'off' position, the magnetic field is short-circuited within the chuck, releasing the workpiece.
What are the advantages of a permanent magnetic chuck?
They offer strong holding power, are easy to operate, require no electricity (making them safe and energy-efficient), and have low maintenance requirements.
What are radial poles on a magnetic chuck?
Radial poles are magnetic segments that extend from the center of the chuck outwards, like spokes on a wheel. This design provides a uniform magnetic field, making it ideal for holding ring-shaped or circular workpieces.
What is the Crystal AA-159 series?
The AA-159 series from Crystal is a range of high-quality round permanent magnetic chucks with radial poles, designed for industrial grinding and turning applications.
Who should choose the Crystal 150mm Round Magnetic Chuck (CRYSTAL-150MM-3506)?
This is the most compact and affordable option, ideal for small workshops or for machining small-diameter workpieces.
Who should choose the Crystal 200mm Round Magnetic Chuck (CRYSTAL-200MM-3507)?
A versatile mid-range option suitable for a wide variety of general-purpose grinding and turning applications.
Who should choose the Crystal 250mm Round Magnetic Chuck (CRYSTAL-250MM-3508)?
This chuck offers a larger clamping area, making it suitable for medium-sized components and providing greater stability.
Who should choose the Crystal 300mm Round Magnetic Chuck (CRYSTAL-300MM-3509)?
A heavy-duty option for large workpieces, offering significant holding power for demanding machining tasks.
Who should choose the Crystal 350mm Round Magnetic Chuck (CRYSTAL-350MM-3510)?
The largest model in this series, designed for maximum holding capacity and for machining very large and heavy circular components.
What is the main difference between the 150mm and 200mm Crystal magnetic chucks?
The primary difference is the diameter and, consequently, the holding capacity. The 200mm model can accommodate larger workpieces and offers a stronger magnetic force than the 150mm model.
Is the 350mm chuck worth the extra cost compared to the 300mm version?
If you regularly machine large, heavy rings or discs, the 350mm model provides the extra diameter and holding power necessary for safety and precision. For smaller parts, the 300mm model is more than sufficient.
Which Crystal round magnetic chuck is best for general engineering workshops?
The 200mm or 250mm models are excellent choices for general-purpose use, offering a good balance of size, holding power, and price for a wide range of applications.
