Hydraulic vise with single- and double-acting actuation
- Published: December 23, 2017
The new KHU6 Hydraulic vise unit from Kurt Workholding comes with both single- and double-acting capabilities, providing convenient adaptation to the user’s preferred clamping method.
The single-acting method uses hydraulic clamping and spring return for unclamping. The double-acting capability uses both hydraulics to clamp and unclamp for faster, more precise setup.
Switching between single and double acting only requires switching out the brass breather fitting with the supplied hydraulic fitting. The KHU6 is available as a retrofit for existing vises and will come standard on all Kurt 6-inch hydraulic vises for the HDH690, HDH691 and 3600H, 3610H, 3630H, XL6H and XL6HR models.
The KHU6 hydraulic unit uses 3200 PSI operating pressure which provides a .25” stroke and 7200 pounds of clamping force. Clamping consistency and improved part quality are benefits of hydraulic vise actuation. Clamping speed is also significantly faster than manually closing and opening vise jaws and can save hundreds of hours over the course of a year, which means a rapid ROI.
