Three automatic systems

The automatic chuck is a mechanical tool designed for precise workpiece holding in machining processes, typically made from alloy steel with a surface hardness of about 55 to 60 HRC. This type of chuck operates with three synchronized jaws and features a clamping diameter ranging from 100 to 250 millimeters. It offers concentricity accuracy of less than 0.03 millimeters and supports rotational speeds up to 4500 RPM. The jaw locking mechanism is usually pneumatic or hydraulic, making it ideal for automated production lines.

The working pressure for the hydraulic system in an automatic chuck ranges from 2.5 to 5 megapascals. The clamping force typically varies between 20 and 60 kilonewtons. The jaws are made of replaceable alloy steel, allowing for quick jaw changes. This chuck is manufactured according to international standards such as ISO 702-3 and DIN 6386, and is widely used in CNC machines, automatic lathes, and industrial assembly lines.
