The jaw design of Schunk’s UVB-HS soft-chuck jaws provides efficient gripping for lathe workholding. With a combination of overheight and angle cutting, it achieves multiple efficiency goals for finishing processes on workpieces.

The unusual jaw height creates a larger clamping surface on the workpiece, reducing deformations. Alternatively, the distance between the workpiece to the chuck face can be increased, optimizing accessibility. Compared to conventional monoblock jaws, this system reduces the jaw weight by at least 20 percent. This increases energy efficiency and shortens the processing time, since the lathe chuck can be accelerated and braked faster. At the same time, the reduced jaw centrifugal force enables higher holding forces on the workpiece, increasing process reliability.

Angle cutting minimizes the danger of collisions with the turret and improves fluid dynamics during machining. At high speeds, the chuck jaws lower noise emissions by as much as 10 dB, which halves the level of perceived noise. Since less cooling lubricant is swirled around the machining area, it is easier to see the machining process. By the same token, fewer aerosols are released when the machine is opened.

The jaws are available for wedge-bar lathe chucks with straight serration in sizes 200, 250/260 and 315. They can be turned individually to the desired diameter.

    A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.

  • A Study Of The Steady Rest

    When the length and stiffness of a workpiece make it difficult to machine without distorting or deflecting the part, many manufacturers turn to the steady rest as a workpiece support device. This is especially true for long axles, shafts and similar parts used in automotive or heavy equipment applications, and in oil drilling components. The most common application is to support a workpiece during turning or milling and, increasingly, during secondary operations such as ID drilling, boring and producing end face bolthole patterns.
