NCA
For the highest precision of your workpieces, the NCA, with its mechanical power amplifier is the ideal solution. The NCA is particularly suitable for use in machining centres, both horizontally and vertically.
- Jaw configuration guarantees highest accuracy
- Spindle can be removed in 10 s. to screw on the clamp centrally
- Integrated step-bar quick-change system

Work pieces that are susceptible to distortion can be ideally machined due to the precisely adjustable clamping force preselection (guaranteed exactly reproducible clamping force). Simple and quick adjustment of the clamping range by means of the integrated crank. In addition, the NCA is fully compatible with the ALLMATIC clamps TC, LC, NC8, and that at a competitive price!

FAQ – frequently asked questions
All relevant dimensions and technical data are compatible with ALLMATIC types TC, LC and NC8.
This means that the vises can be interchanged and existing jaws can also be used.
Both vises are absolutely equivalent in quality, each with their own special unique advantages. Our Kesel service team will be happy to show you which vise is the better solution for your application.
Yes, with the integrated mechanical force amplifier, a high clamping force can be achieved without any problems. Due to the fine force adjustment, this can be reproduced very well.
For the 90 mm size, the desired clamping force is adjusted manually with a sliding ring; for the 125 mm and 160 mm sizes, it is adjusted with a Allen key SW6 in the groove on the front side.
No, the chips can be flushed out of the NCA High Pressure Machine Vise through the large elongated holes on the side or on the face of the fixed jaw.
In addition, the spindle is protected against chips with highly effective seals.
These are spring-loaded pressure points. Our Kesel step ledges (support ledges) can be clicked into these.
