Precautions and methods in the use of the Ultra Disk
1, the workpiece should be placed as much as possible to occupy the magnetic pole, in order to get a greater attraction, and do not align the magnetic pole;
2, the super suction cup is a set of magnetic clamping tools, it is composed of the magnetic suction cup body and other optional accessories, should use the accessories as much as possible, in order to achieve precise and fast clamping for more workpiece should appropriate choice of auxiliary gear block;
3、For large and irregularly shaped workpieces on the bottom surface, multiple suction cups can be used in combination to complete clamping;
4, for large and flat bottom workpieces, can choose the auxiliary block pad high to complete clamping;
5、For horizontal milling or drilling machine, it can be used with tripod side suction cups to complete clamping from the face;
6、For smaller workpieces, multiple workpieces can be clamped at one time to achieve the purpose of improving work efficiency (because the workpiece is too small, please choose the auxiliary block for the outermost workpiece);
7、In order to ensure the parallelism between the plane of the suction cup and the working platform surface of the machine tool, after the suction cup is installed in place, the user should carry out fine milling on the working surface of the suction cup.

Suction power Super suction, super suction, superimposable magnetic force, increases according to the contact area of the workpiece and can be used for powerful milling. Weak suction force, magnetic force cannot be superimposed, does not increase according to the contact area of the workpiece, usually used in grinding and electro-machining machines.
Precision The panels are very rigid and stable and do not deform during use, allowing for precision machining. Poor steel and stability of the panel, easily deformed during use, especially in large areas.
Uniform and constant magnetic force can be predicted Unique rectangular technology, a constant magnetic force for different shapes, sizes, quantities, and positions of the suction cups. The magnetic force varies irregularly according to shape, size, quantity, and position.
The direction of the force on the workpiece Four horizontal directions are available for machining in the horizontal XY direction, suitable for milling. Horizontal in both directions, suitable for single-direction machining only.
Magnetic circuit construction The magnetic poles are in a long square, the beam penetrates evenly into the bottom of the workpiece, it is shallow and dense, usually the part above 1cm does not show magnetism. Large variations in the magnetic beam may make the process magnetic, thus affecting machining accuracy or magnetizing the tool and machine spindle.

Industry Knowledge Development

A permanent magnetic chuck is a device used in machining operations, particularly in metalworking, for holding ferromagnetic workpieces securely in place during machining operations. These chucks use permanent magnets to generate a magnetic field that holds the workpiece.

Here are some general performance characteristics that are desirable in a permanent magnetic chuck:
Holding Force: The holding force of a magnetic chuck refers to its ability to securely hold the workpiece in place during machining. Higher holding force ensures stability and prevents movement or vibration of the workpiece.
Uniform Magnetic Field: A uniform magnetic field across the entire surface of the chuck is crucial for consistent holding power. It ensures that the magnetic force is evenly distributed, which helps in maintaining accuracy and preventing distortion during machining.
Magnetic Flux Density: Magnetic flux density determines the strength of the magnetic field generated by the chuck. Higher flux density translates to a stronger holding force and improved stability.
Magnetic Field Control: Some magnetic chucks offer the ability to control the magnetic field strength. This feature allows the operator to adjust the holding force according to the specific requirements of the machining operation.
Rigidity and Durability: A reliable magnetic chuck should be rigid and durable to withstand the forces and stresses encountered during machining. It should be resistant to wear and deformation to ensure consistent performance over time.
Easy Operation: An effective magnetic chuck should be user-friendly, allowing for easy and efficient setup and removal of workpieces. Quick and secure clamping mechanisms can enhance productivity and save time.

The PMSC Super permanent magnetic chuck offers several advantages over traditional magnetic chucks. Here are some of the key advantages:
Strong magnetic force: The PMSC Super permanent magnetic chuck generates a strong magnetic force, ensuring secure and reliable holding of workpieces. It can effectively hold ferromagnetic materials with high precision, stability, and rigidity.
Permanent magnetic properties: Unlike electromagnetic chucks that require continuous power supply, the PMSC Super permanent magnetic chuck is magnetized permanently and does not rely on external power. This eliminates the risk of power failure or fluctuations affecting the workholding, resulting in increased operational safety and reduced downtime.
Energy efficiency: As the PMSC Super permanent magnetic chuck does not require electrical power during operation, it offers significant energy savings compared to electromagnetic chucks. It helps reduce power consumption and contributes to a more sustainable and cost-effective manufacturing process.
Uniform magnetic field distribution: The Super permanent magnetic chuck is designed to provide a uniform magnetic field across the entire surface, ensuring even clamping force and distribution of magnetic flux. This uniformity helps maintain consistent holding power and improves the accuracy and stability of machining operations.
Low maintenance: The PMSC Super permanent magnetic chuck has no moving parts or electrical components, making it virtually maintenance-free. There are no coils, cables, or control systems to maintain or repair, reducing the need for servicing and minimizing overall maintenance costs.
Versatility: The Super permanent magnetic chuck is compatible with various machining processes, including milling, grinding, turning, and EDM (electrical discharge machining). It can securely hold a wide range of workpiece sizes, shapes, and weights, making it suitable for diverse industrial applications.
Easy operation: The magnetic force of the PMSC Super permanent magnetic chuck can be quickly activated or deactivated by a simple lever or switch, enabling fast and efficient workpiece loading and unloading. This ease of operation enhances productivity and saves time during setup and changeovers.
High temperature resistance: The PMSC Super permanent magnetic chuck exhibits excellent thermal stability, allowing it to withstand high operating temperatures without a significant loss of magnetic force. This feature is particularly advantageous in applications that involve high-speed machining or thermal processes.

Overall, the PMSC Super permanent magnetic chuck offers superior holding power, energy efficiency, ease of use, and low maintenance requirements, making it a valuable tool in precision machining and manufacturing operations.
