What is the lathe chuck?
Kawatatec is widely known in Japan, Asia and North America as one of the few manufacturers of large lathe chucks in the world. In North America, in particular, our “NOBEL CHUCK” is known as a highly reliable brand that has been around since the 1970s. Below, we will explain in detail what the lathe chuck is.
The object shown in the figure in the upper left is a chuck. A chuck is a tool used to “hold” cylindrical or square materials to be processed by a machine tool. A chuck is required to have a stronger gripping force than the force needed to rotate heavy workpieces such as steel as well as apply a tool to them for processing.
In the photo of the apple being cut in the upper right, the chuck is the “hand” that grips the apple.
"Holding” is one of the most basic elements of processing materials.
