Modern Machine Shop 161 TOOLING AND WORKHOLDING techspex.com IN PARTNERSHIP WITH: Search Machines Smarter. Machining Center Drill/Tap Boring Mill Milling Machine Machine Type: The Machine Tool Search Engine Jaws Increase Efficiency in Finish Machining 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, the company says. Also, fewer aerosols are released when the machine is opened. | Schunk Inc. | 800-772-4865 | schunk.com
