Operational Care & Handling Guidelines
- Keep the top plate clean and free of chips, swarf, and debris to maintain optimal magnetic contact
- Apply a light coat of anti-rust oil on the working surface to prevent corrosion during idle periods
- Avoid dragging heavy ferrous objects across the plate to preserve surface flatness and parallelism
- Store the chuck in a dry environment and engage the magnetic field only when actively securing parts
- Periodically inspect the mechanical lever mechanism to ensure smooth operation and reliable engagement
Magnetic Technology & Holding Principle
- Permanent magnet circuit generates a strong, stable holding force without external power sources
- Close-pole arrangement concentrates magnetic flux directly beneath the workpiece for maximum grip
- Mechanical lever mechanism safely redirects magnetic lines to instantly release parts without demagnetization
- Non-conductive top plate prevents workpiece damage and eliminates risk of electrical arcing during machining
- Consistent flux density reduces part shift during heavy cuts, improving surface finish and dimensional accuracy
Quality Standards & Compliance
- Manufactured strictly in accordance with IS-4816-1987 standards for dimensional and magnetic accuracy
- Crystal Series AA-153 series delivers consistent performance across the entire product family
- Rigorous quality control ensures every unit meets industrial tolerances for parallelism and flatness
- Built for continuous shop floor use with materials selected for long-term wear resistance
- Standardized pole gap and flux distribution guarantee repeatable results across all model sizes
Precision Manufacturing Applications
- High-precision surface grinding of thin, small, or low-profile steel plates without deformation
- Secure holding of small components during light milling, shaping, and EDM machining operations
- Precision toolroom inspection, layout, and calibration setups on precision surface plates
- Tool and die manufacturing requiring distortion-free clamping of sensitive or complex geometries
- Optimized for intricate workpieces that demand stable positioning and minimal vibration during processing
Core Design & Operational Features
- Heavy-duty permanent magnetic chuck with close-pole configuration for enhanced holding resolution
- Mechanical ON/OFF lever ensures reliable operation without electrical power or heat generation
- Premium quality top plate guarantees uniform magnetic field distribution and excellent parallelism
- Designed to securely clamp smaller, thinner, or more intricate workpieces with consistent grip
- Available in model variations ranging from AA-15301 to AA-15314 for diverse workspace requirements
- Base lengths span 250mm – 750mm, widths 150mm – 300mm, heights 65mm – 70mm
- Uniform 14mm magnetic pole gap creates a denser magnetic flux line pattern across the working surface
More questions buyers ask
What is a permanent magnetic chuck?
A permanent magnetic chuck is a workholding device that uses permanent magnets to securely hold ferromagnetic workpieces during machining operations like grinding, milling, and drilling.
How does a permanent magnetic chuck work?
It uses a system of fixed and movable magnets. A lever is used to align or misalign the poles of the magnets. When aligned, the magnetic field is directed through the workpiece, holding it firmly. When misaligned, the field is short-circuited within the chuck, releasing the workpiece.
What are the advantages of a permanent magnetic chuck over an electromagnetic one?
Permanent magnetic chucks do not require electricity to operate, making them safer in case of a power failure. They are also more portable and do not generate heat, which can affect workpiece accuracy.
What is a 'close pole' magnetic chuck?
A close pole chuck has a smaller gap between its magnetic poles. This design is ideal for securely holding smaller or thinner workpieces that might not be held effectively by a standard pole pitch chuck.
What applications are these Crystal magnetic chucks suitable for?
These heavy-duty chucks are designed for precision surface grinding, as well as light milling, drilling, and inspection tasks on flat, ferrous metal parts.
Do I need to be an expert to use this?
No, operation is straightforward via a manual lever. However, always follow the safety guidelines provided with the product for proper handling and to ensure maximum holding power.
What is the warranty on Crystal magnetic chucks?
Crystal magnetic chucks typically come with a 1-year manufacturer's warranty against manufacturing defects. Please confirm the specific warranty details at the time of purchase.
Can I get a GST invoice for my purchase?
Yes, we provide a GST invoice for all purchases, allowing you to claim input tax credit for your business.
Who should choose the Crystal AA-15301 Permanent Magnetic Chuck?
The AA-15301 is the most compact and affordable option in the series. It is ideal for workshops with smaller surface grinders or for holding smaller workpieces with high precision.
Who should choose the Crystal AA-15314 Permanent Magnetic Chuck?
The AA-15314 is one of the largest models in this series, offering a substantial surface area for securing large and heavy workpieces for heavy-duty grinding operations.
What is the main difference between the AA-15301 and the AA-15305?
The primary difference is size and price. The AA-15305 has a significantly larger surface area (and higher price) than the AA-15301, allowing it to hold larger workpieces. The choice depends on your machine's table size and the typical size of the jobs you handle.
How do I choose the right size Crystal magnetic chuck?
Consider the table size of your grinding or milling machine and the dimensions of the largest workpiece you intend to machine. The chuck should fit comfortably on your machine table and be large enough to support your workpiece adequately.
Are larger chucks like the AA-15313 more powerful than smaller ones like the AA-15302?
While all chucks in this series provide strong clamping force, the total holding power increases with the size of the chuck due to the larger magnetic area. A larger chuck is necessary to securely hold a larger and heavier workpiece, not just because it's 'more powerful' in general.
