Designer Jaws Boost Finishing-Machine Efficiency

SCHUNK claims the intelligent jaw design of its UVB-HS soft chuck jaws defines a new class of efficiency in lathe chuck technology. With a combination of over-height and angle cutting, it achieves a numerous efficiency effects during finish machining of workpieces. The unusual jaw height allows for a larger clamping surface on the workpiece, which reduces deformations. Alternatively, the distance between the workpiece to the chuck face can be increased and thus accessibility can be optimized.

 

In comparison to conventional mono-block jaws, the UVB-HS reduces the jaw weight by at least 20% depending on the size. 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 allows for higher holding forces on the workpiece, which means increased process reliability.

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

Angle cutting minimizes the danger of collisions with the turret and improves the fluid dynamics during machining. At high speeds, UVB-HS chuck jaws lower noise emissions up to 10 dB, which halves the level of the perceived noise. Since significantly lower cooling lubricant is swirled around the machining area, it is easier to see the machining process. This also lowers the need for aerosols in the air when the machine is opened. For greater knowledge, visit SCHUNK.
