CarvLock® CTHDL Manual Cluster Towers

Kurt® Workholding’s CarvLock® CTHDL manual cluster towers are designed for use with mid-size and larger CNC machining centers, including horizontal and vertical machining centers with a fourth axis and/or indexable tables. These manually operated, eight station vise towers are capable of producing up to 7,460 lbs. of clamping force at just 70 ft-lbs. of torque. They provide exceptional workpiece immobility while dampening cutter-induced vibration. Ductile iron column construction ensures strength, rigidity, and long term accuracy.
A self-adjusting holding block on either the front jaw or back jaw allows for easy clamping of same or differently-sized parts. To provide faster operation, an adjustable pre-load feature reduces the number of handle turns required for opening and closing the clamping stations.
With eighteen CTHDL models available, with 4” or 6” jaws, it’s easy to find the right manual cluster tower for your unique workholding needs. Order the CarvLock® CTHDL cluster tower your application requires, or contact Kurt Workholding for more information.
