If the value is out of the specified scope, adjust the position of correspinding claw to meet the accuracy requirements.   Note:Measurement can also be conducted by inserting a long mandrel of size matching the center hole of tail chuck into the chuck center, and the mandrel shall be 1000-2000mm long.   3.Measure the ipper bus bar and side bus bar of mandrel Measure the ipper bus bar of mandrel(namely the central upper bus bar of mandrel).The magnetic base is fixed on the machine (not on the mounting table of tail chuck),with the pointer pointing to the position shown in the figure.Move the entire mounting table to the left and right,measure and unsure that the upper bus bar value is below 0.05mm.Upper bus bar value exceeding the required scope can be adjusted by inserting copper sheet at two points on the bottom mounting surface of chuck. Measure the side bus bar of mandrel(namely the central side bus bar of mandrel).The magnetic base is fixed on the machine(not on the mounting table of tail chuck), with the pointer pointing to the position shown in the figure,Move the entire mounting table to the left and right,measure and ensure that the side bus bar value is below 0.05mm.Side bus bar value out of the scope can be adjusted by slightly rotating the mounting base of chuck. After adjustment,check again if the bus bar accuracy meets standard.If the value is still out of the scope,repeat the adjustment till the error value of ipper bus bar and side bus bar of tail chuck is below 0.05mm.   Note:Measurement can also be conducted by inserting a long mandrel of size matching the center hole of tail chuck into the chuck center, and the mandrel shall be 1000-2000mm long.     4.With the center of tail chuck as the benchmark(the rotation center of tail chuck),measure the verticality of the reference plane on the back of the main chuck relative to the rotation center of tail chuck.

The differences between a pneumatic chuck and a manual chuck: 1. Operation: A pneumatic chuck is operated using compressed air, while a manual chuck requires manual force to tighten or loosen the grip on the workpiece. Pneumatic chucks provide a quicker and more automated clamping process, whereas manual chucks require physical effort to operate.   2. Clamping Force: Pneumatic chucks have adjustable clamping force that can be controlled by adjusting the air pressure supplied to the chuck. Manual chucks, on the other hand, rely on the strength and force applied by the operator to tighten the grip. Pneumatic chucks typically provide higher clamping forces and more consistent gripping compared to manual chucks.   3. Speed and Efficiency: Pneumatic chucks allow for faster and more efficient workpiece changes. The clamping and releasing process can be automated, reducing setup time and increasing productivity. Manual chucks require manual tightening and loosening, which can take more time and effort.   4. Precision and Repeatability: Pneumatic chucks offer higher precision and repeatability in terms of clamping force, ensuring consistent gripping and minimizing slippage during machining operations. Manual chucks may have slight variations in clamping force, leading to potential inconsistencies in gripping.   5. Ease of Use: Pneumatic chucks are generally easier to use, as they have simple controls or switches to operate the clamping mechanism. On the other hand, manual chucks require more skill and effort to tighten or loosen the chuck accurately.   6. Versatility: Manual chucks are often limited in terms of the range of workpiece sizes they can accommodate. Pneumatic chucks, with their adjustable gripping mechanisms or interchangeable jaws, can handle a wider range of workpiece sizes and shapes.   7. Automation Integration: Pneumatic chucks are more easily integrated into automated systems or CNC machines, as they can be controlled by solenoid valves or other pneumatic control systems. Manual chucks require manual operation, making them less suitable for automation.   Ultimately, the choice between a pneumatic chuck and a manual chuck depends on the specific needs of the application. Pneumatic chucks are favored in industrial settings where speed, precision, and automation are crucial, while manual chucks may be more suitable for simpler or smaller scale operations that do not require frequent workpiece changes or high clamping forces.

Here are some features of pneumatic chucks:   1. Air-powered Operation: Pneumatic chucks utilize compressed air to operate. This allows for quick and precise clamping and releasing of workpieces. 2. Adjustable Clamping Force: Pneumatic chucks often have adjustable clamping force, allowing users to tailor the grip strength to their specific needs. The clamping force can be controlled by adjusting the air pressure. 3. Versatility: Pneumatic chucks can hold a wide range of workpiece sizes and shapes. They often include jaws or grippers that can be easily adjusted or changed to accommodate various workpiece geometries. 4. Quick and Easy Operation: Pneumatic chucks are designed for fast and efficient workpiece changes. The clamping and releasing process is usually automated or controlled by a simple switch or valve, reducing the setup time. 5. High Clamping Accuracy: Pneumatic chucks provide strong and consistent clamping force, ensuring secure gripping of workpieces. This enhances machining precision and reduces the risk of slippage during operations. 6. Reduced Vibrations: Pneumatic chucks can help dampen vibrations, especially in high-speed machining applications. The air cushioning effect minimizes tool chatter and improves the surface finish of machined parts. 7. Safety Features: Pneumatic chucks often come with safety mechanisms, such as built-in pressure sensors or overload protection, to prevent excessive clamping forces that could damage the workpiece or the chuck itself. 8. Durability and Reliability: Pneumatic chucks are typically built with robust materials and components to withstand high forces and repeated use. They are designed for long-term reliability in industrial environments. 9. Compatibility: Pneumatic chucks can be integrated with various automated systems or CNC machines, allowing for seamless integration into existing production processes. 10. Low Maintenance: Pneumatic chucks generally require minimal maintenance, as they have fewer moving parts compared to some other types of chucks. Regular cleaning and lubrication of the air supply system are typically sufficient to keep them operating smoothly.   These features make pneumatic chucks popular in many industries, including manufacturing, woodworking, metalworking, and automotive, where precise clamping and quick workpiece changes are required.

A pneumatic chuck is a type of chuck used in machining and tooling applications to securely hold and clamp workpieces. It utilizes compressed air to operate, providing a quick and efficient clamping mechanism. Pneumatic chucks are typically used in industrial settings where precision, speed, and reliability are essential.   These chucks consist of a gripping mechanism, often with movable jaws or grippers, that can be adjusted to accommodate different workpiece sizes and shapes. The clamping force is controlled by adjusting the air pressure supplied to the chuck. This allows for customization of the grip strength according to the specific requirements of the machining operation.   Pneumatic chucks offer several advantages, such as ease of operation, high clamping accuracy, versatility, and compatibility with various automated systems. They are commonly used in CNC machines, lathes, milling machines, and other equipment where secure holding of workpieces is necessary.
