CarvLock® CTHDH Hydraulic Cluster Towers

Kurt® Workholding’s CarvLock® CTHDH hydraulic cluster towers are engineered for use with horizontal CNC machining centers and vertical CNC machining centers with indexable tables. The unique design of these vise towers provides workpiece immobility and dampens cutter-induced vibration.
All models in the CTHDH line of hydraulic workholding towers offer eight work stations and can provide up to 7,100 lbs. of clamping force at 5,000 hydraulic psi. Hydraulic components are integrated into the vise and tower body to conserve space on the machining table. Towers can easily be converted to manual operation when needed.
We offer sixteen hydraulic Cluster Tower® models, making it easy to find the right option for your workholding needs. Order a CarvLock CTHDH cluster tower for your application, or contact Kurt Workholding for more information.
See individual product listings for additional information and specifications. All models are protected by Kurt’s Lifetime Iron Clad Warranty.

Hydraulic Cluster Towers for All Machining Operations

CTHDH cluster towers are identical in capacity and features to our CarvLock HD manual cluster towers, with the added benefit of hydraulic actuation. The hydraulic piston is an integral part of the vise nut within the vise and tower body, which reduces the tower’s footprint and minimizes spindle travel, part to part, for greater throughput without sacrificing holding accuracy. Eight workstations allow for simultaneous machining of multiple parts, while elevated columns make it easy to clear chips and contaminants.
Our CTHDH (Cluster Tower® – Heavy Duty – Hydraulic) cluster towers are among the most compact and high density hydraulic vise towers on the market today. Available with 300 mm, 400 mm, 500 mm, or 630 mm bases. Ductile iron construction ensures superior strength, rigidity, and long term accuracy.
Multiple jaw options are available to fit your unique application, including machinable aluminum jaws, machinable ductile iron jaws, and aluminum fixture plates. Jaws are indexable 180°.
