Round Jaws
Buy OnlineAlso known as Pie Jaws® , Full Grip Jaws and Full Circle Jaws
Round Chuck Jaws are used widely in holding wheels, rolled rings and other thin walled parts where normal jaws will cause part shape distortion or marring. Irregularly shaped parts, thin walled parts and non-cylindrical parts are common applications where Round jaws are used. Round chuck jaws are used where increased surface gripping is necessary with minimal part marring.
Round Chuck jaws are available in various diameters and heights. Oftentimes it is necessary to hold an oversized part. In such cases Oversized round jaws may be used. For example a 14" diameter part needs to be held on a 10" diameter chuck. In such a case the part may be held with a 15" diameter set of round jaws that have been made with the critical dimensions to fit a 10" chuck. VERY IMPORTANT : when using an oversized set of Round Jaws - reduce the spindle speed to allow for the increased mass (centrifugal force on the jaws).
Conversely, sometimes it is necessary to hold a small thin walled part. In such cases it may be possible to use Undersized diameter Round Jaws. Using undersized diameter Round Jaws can result in a significant cost savings in the price of the jaws.
