Operational Maintenance & Handling Guidelines
- Wipe chuck surface with dry cloth after each shift to remove residual coolant and chips
- Store workpieces flat to prevent surface marring and preserve magnetic contact integrity
- Inspect ON-OFF knob mechanism periodically to ensure smooth rotational engagement
- Avoid dropping heavy ferrous objects on the face plate to maintain flatness tolerances
- Keep pole gap area clean to sustain optimal magnetic field performance over time
Magnetic Flux & Holding Mechanism
- Close pole gap configuration ensures uniform magnetic flux distribution across the face
- 14mm pole spacing – optimized for reliable retention of thin circular parts
- Mechanical switch design eliminates electrical dependency for consistent holding
- Rapid engagement and release cycles minimize non-cutting time during production runs
- Predictable magnetic response reduces part slippage during high-speed grinding operations
Sealed Construction & Material Integrity
- Completely sealed internal design shields magnets from coolant exposure and moisture
- Robust housing prevents metal chip accumulation from compromising magnetic performance
- Durable surface finish resists wear during repeated part loading and unloading cycles
- Maintains structural rigidity under continuous machine vibration and cutting forces
- Extends service life by protecting sensitive internal components from contaminants
Precision Workholding Applications
- Ideal for secure clamping on rotary surface grinding machines and cylindrical grinders
- Optimized for small-diameter discs, rings, washers, and precision tooling
- Supports light turning, boring, and facing operations on conventional or CNC lathes
- Enables precise alignment and inspection tasks on toolroom rotary tables
- Handles circular workpieces efficiently without complex fixture modifications

More questions buyers ask
What is a round magnetic chuck used for?
A round magnetic chuck is primarily used for securely holding circular workpieces like discs, rings, and washers during grinding, turning, or inspection operations.
How does the Crystal AA-159 magnetic chuck work?
It uses a mechanical ON-OFF knob to engage and disengage the internal high-grade magnets, providing a secure grip without needing electrical power.
Is the Crystal magnetic chuck suitable for CNC machines?
Yes, it is ideal for rotary surface grinding machines, cylindrical grinders, and can support light turning or boring operations on lathes.
What diameters are available for the Crystal AA-159 series?
The series is available in 100mm, 150mm, 175mm, and 200mm diameters, all with a 60mm height.
Does this chuck require electricity?
No, the Crystal AA-159 series features a mechanical switch design, eliminating the need for electrical power.
How do I maintain the magnetic chuck?
Wipe the surface with a dry cloth after each shift, keep the pole gap clean, and avoid dropping heavy objects on the face plate.
Can I use this for thin circular parts?
Yes, the 14mm pole spacing is optimized for reliable retention of thin circular parts.
Is the chuck sealed against coolant?
Yes, it features a completely sealed internal design to shield magnets from coolant exposure and moisture.
What is the height of these chucks?
All models in the Crystal AA-159 series have a compact 60mm height profile.
Are these chucks suitable for high-speed grinding?
Yes, the predictable magnetic response reduces part slippage during high-speed grinding operations.
Who should choose the 100mm Crystal Magnetic Chuck?
The 100mm model is best for users handling small-diameter discs, precision tooling, and light toolroom tasks.
Who should choose the 150mm Crystal Magnetic Chuck?
The 150mm model is ideal for standard cylindrical grinding and medium-sized circular workpieces.
Who should choose the 175mm Crystal Magnetic Chuck?
The 175mm model is recommended for users needing extra holding capacity for larger rings and washers.
Who should choose the 200mm Crystal Magnetic Chuck?
The 200mm model is the best choice for high-volume production environments requiring maximum surface area.
How does the 100mm model compare to the 200mm model?
The 100mm model is compact and suited for small precision parts, while the 200mm model provides the largest surface area for heavy-duty, high-volume production.
Are all Crystal AA-159 chucks the same height?
Yes, all models from 100mm to 200mm share a consistent 60mm height for easy machine table integration.
Which model is best for heavy-duty grinding?
The 200mm model is the most suitable for heavy-duty applications due to its larger surface area and robust holding capacity.
