This is a general type chuck with the chucking portion centered, and with the stopper face aligned to edge face. This type of chuck securely clamps even raw material cast/forged parts with draft (up to 20°) to ensure consistent dimensional accuracy in the axial direction even during heavy-duty cutting.
Two-jaw or three-jaw structure is available. The chuck can be easily changed for either OD (outer diameter) or ID (inner diameter) chucking.
Jaws, stoppers and other upper parts are designed according to customer’s individual needs. Also, a wide variety of jaws are selectable for various kinds of workpieces.
The carbide-insert jaw and special-shape jaw are effective for machining difficult-to-cut materials. The high-tensile aluminum jaw is suitable for high-speed machining. The Master/Jawpiece type and Quick Jaw Change System(Q.J.C.) are useful for Many kind of workpiece/small lot parts machining.

UBL Centralizing
Unparalleled high performance in the machining of castings and forgings
The UBL ball lock chuck developed by N.A. Woodworth [now FORKARDT] is an oscillating power chuck that offers unparalleled performance in the machining of die cast and forged materials. Since 1969, when we acquired the exclusive right to manufacture and sell Woodworth patented products such as its UBL and diaphragm chucks in Asia, our chucks have been used as indispensable work-holding devices in the machining of automobile parts, and our unique UBL new design has been used to meet the most difficult requirements. We are always ready to respond to your needs.
A broad chucking range allows optimum machining.
The UBL Chuck is a locking type power chuck that offers high levels of gripping performance, rigidity and durability to allow secure gripping of cast or forged materials with a draft angle and workpieces with an overhang, which conventional chucks can not grip. Also, they can improve the roundness of thin-walled parts and respond to difficult-to-grip complex-shape workpieces.
Our Designs based on original technology and know-how.
In addition to such basic types as Centralizing type (for general chucking) and Compensating type (for chucking with respect to boss or center hole), many other types such as ON-OFF (switchover type), Long Stroke, Large-Diameter Through Hole, and 6-Jaw types (for ID and OD chucking) are available as standard. Also, depending on applications, Quick Jaw, Special Jaw-actuator (base jaw), or Light-weight Jaw can be selected.Since we design the entire chuck, with safety and machining performance taken into account, reliable and comfortable operations will be ensured. * While there are many copies and similar products on the market, we always aim for the most advanced quality and performance with our long-accumulated technology, diverse repertoire, and know-how in materials, heat treatment, and processing.
