More questions buyers ask
What is a permanent magnetic chuck?
A permanent magnetic chuck is a work-holding device that uses permanent magnets to securely clamp ferrous metal workpieces for precision machining operations like grinding, milling, and inspection. It does not require a continuous electrical power source to maintain its holding force.
How does a micro pitch magnetic chuck work?
A micro pitch chuck has a finer arrangement of magnetic poles compared to standard chucks. This creates a more uniform magnetic field, making it ideal for securely holding small, thin, or delicate ferrous parts that might not be held effectively by a standard pole chuck.
What are the applications of a rectangular magnetic chuck?
Rectangular magnetic chucks are primarily used on surface grinders, milling machines, shapers, and planers. They are ideal for holding flat, rectangular, or square workpieces for various machining and finishing operations.
What are the advantages of a permanent magnetic chuck over an electromagnetic one?
Permanent magnetic chucks are safer as they don't release the workpiece during a power failure. They are also more energy-efficient as they don't require electricity to maintain their grip, and they generate less heat, which helps in maintaining machining accuracy.
Is the Crystal magnetic chuck compliant with any IS standards?
Yes, this Crystal magnetic chuck is manufactured to meet the accuracy standards of IS-4186-1987, ensuring high precision and reliability in your work-holding setup.
What material can be held by this magnetic chuck?
This chuck is designed to hold ferromagnetic materials, which are materials that are strongly attracted to magnets, such as iron, steel, and certain alloys.
Does this chuck require an external power supply?
No, being a permanent magnetic chuck, it uses an internal system of magnets that are turned on and off by a mechanical lever. It does not require any external electrical power to maintain its holding force.
Is there any residual magnetism after switching it off?
No, the design includes a feature that ensures there is no residual magnetism left on the workpiece after the chuck is switched off, allowing for easy removal of the finished part.
What is the warranty on Crystal magnetic chucks?
All Crystal products sold by Gearo come with a standard manufacturer's warranty against manufacturing defects. For specific warranty details and duration, please refer to the product documentation or contact our support team.
Can I get a GST invoice for my purchase?
Yes, we provide a GST invoice for all purchases. You can claim input tax credit on your business purchases.
Do you offer pan-India delivery?
Yes, we offer delivery across India for all our products. Your order will be shipped to your registered business address.
Who should choose the Crystal 200x150mm magnetic chuck (AA-15926)?
The 200x150mm model is ideal for users working with smaller workpieces or on compact benchtop grinding machines. It's a great choice for tool rooms, training institutes, and shops that handle small-batch precision jobs.
Who should choose the Crystal 250x150mm magnetic chuck (AA-15927)?
The 250x150mm variant offers a slightly larger surface area, making it suitable for small to medium-sized components. It's a versatile option for general-purpose surface grinding and light milling tasks.
Who should choose the Crystal 300x150mm magnetic chuck (AA-15928)?
This mid-range 300x150mm size is a popular choice for workshops that need a balance between compact size and the ability to handle a wider range of workpiece dimensions. It fits well on most standard surface grinders.
Who should choose the Crystal 350x150mm magnetic chuck (AA-15929)?
The 350x150mm model is designed for medium-duty applications and can accommodate longer workpieces. It is well-suited for production environments where a larger clamping area is frequently required.
Who should choose the Crystal 450x150mm magnetic chuck (AA-15930)?
As the largest variant in this series, the 450x150mm chuck is built for heavy-duty grinding and machining of large components. It is the best choice for production floors and heavy engineering workshops.
What is the main difference between the AA-159 series variants?
The primary difference between the variants is their size (length x width). All variants share the same 60mm height, micro-pitch design, and high-quality Crystal manufacturing. The choice depends entirely on the size of the workpieces you typically handle.
How do I choose the right size of magnetic chuck for my machine?
To choose the right size, 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's table while providing adequate clamping area for your parts.
Are the smaller chucks as powerful as the larger ones?
The magnetic holding power per unit area is consistent across all sizes in the series. However, the total clamping force of a larger chuck will be greater due to its larger surface area, allowing it to hold bigger and heavier workpieces more securely.
