Frequently asked
How do I select the correct pole gap size for my workpieces?
Choose the 16mm gap for smaller components or the 19mm gap for medium to large workpieces.
Is this chuck compatible with standard machine tables?
Yes, the AA-152 series features standardized mounting dimensions for broad machine compatibility.
What maintenance is required for the mechanical switching mechanism?
Periodic lubrication of the lever pivot and cleaning of the top plate ensures optimal function.
Can this chuck be used for non-ferrous materials like aluminum?
No, it is specifically engineered for ferromagnetic workpieces only.
More questions buyers ask
What is a permanent magnetic chuck?
A permanent magnetic chuck is a workholding device that uses high-strength permanent magnets to secure ferromagnetic workpieces for machining without needing electricity.
Why choose Crystal magnetic chucks?
Crystal chucks are built to IS-4816-1987 standards, offering high precision, durability, and reliable clamping force for professional industrial use.
Are these chucks suitable for milling?
Yes, they are suitable for light to medium milling, shaping, and planing operations on ferromagnetic materials.
Do I need electricity to operate this chuck?
No, it operates via a mechanical lever, making it safer and immune to power outages.
How do I maintain the chuck?
Keep the top plate clean and periodically lubricate the lever mechanism to ensure smooth operation.
What materials can be clamped?
Only ferromagnetic materials (like steel and iron) can be clamped. Non-ferrous metals like aluminum or brass will not hold.
What is the pole gap?
The pole gap is the distance between magnetic poles. Smaller gaps (16mm) are better for small parts; larger gaps (19mm) are better for medium-to-large parts.
Is the top plate replaceable?
The top plate is precision-ground and integral to the chuck's accuracy; it should be maintained rather than replaced.
Can it be used on a surface grinder?
Yes, it is specifically designed for secure workholding during precision surface grinding.
Does it come with a warranty?
Crystal products are known for industrial quality; please check the specific invoice for warranty terms provided by the dealer.
Who should choose the AA-15201 model?
The AA-15201 is ideal for small-scale toolroom tasks and precision grinding of compact components.
Who should choose the AA-15218 model?
The AA-15218 is designed for large-scale industrial machining, offering the largest surface area for heavy-duty workpieces.
How does the 16mm pole gap compare to the 19mm gap?
The 16mm gap provides higher density for smaller parts, while the 19mm gap offers deeper magnetic penetration for larger, thicker workpieces.
Are these chucks better than electromagnetic ones?
They are safer during power failures and generate no heat, which prevents thermal distortion of the workpiece.
How do I ensure the chuck is level?
The chuck is manufactured to high parallelism tolerances; ensure your machine table is clean before mounting.
