Centric clamp KASTR CU-T 77

A new clamp KASTR CU-T 77 is a special type of a centric clamp with hard toothed jaws developed for four-axial and five-axial machining, but it can also be used for many applications on three-axial machining centers.

The clamp is designed for a primary clamping on 3 mm without any limitation by the cutting conditions and the machine possibilities. By the geometry optimization, seeking for new materials, and by the heat treatment we have moved the workpiece holding possibilities to a new dimension where the clamped semi-product mass - at the clamping on 3 mm - exceeds the clamp mass twenty times absolutely safely at any inclination and in any roughing process.

Unlimited possibilities of setting

The clamp can be simply set into a standard precise cross groove, without the clamp body overrunning the jaw width. As a result of that, more clamps can be set for the clamping of larger workpieces according to any configurations and various arrangements. If you have any zero point system, you can easily modify our clamps KASTR CU-T 77 to the system you have run in.

Without pre-marking

Using most of the competitors clamps, it is necessary to first pre-mark the tooth prints with hydraulic devices. At the clamping of shape parts if the individual clamps are not mutually parallel, it is very complicated, expensive, or even entirely impossible to use the hydraulic pre-marking. Last but not least, the hydraulic pre-marking is an extra operation, which uselessly costs you an expensive work force as well as much time. Our clamps KASTR CU-T 77 need no pre-marking;, it holds a workipeace perfectly.

Surface quality

The clamp KASTR CU-T 77 eliminate the vibrations arising by the machining process. As a result of that, an outstanding quality of the surface can be achieved on a strong machine with a good tool. On our machines we usually achieve the surface quality of Ra 0,2 by front milling and using a suitable tool.

KASTR CU-T 77 is delivered as a set of body of clamp, screw and two jaws, which are enable to by 180° rotation according to currently needs. Clamp is designed for multidimenzional use, it can be easily hanged to "double" clamp by changing screw and adding a central jaw (which is not included in base package). With this modification you can clamp 2 pieces on the same time. When you will want to take the clamp back to base position it is very easy. Just change the screw back. All of this without body of clamp removal.

Clamping dimension

We are manufacturing KASTR CU-T in 2 sizes 170mm and 210mm:
Length 210 mm/170 mm
Dimension v mm
Height 70/70
Width 77/77
Length 210/170

See the full dimension brochure KASTR CU-T 77

Jaws

Together with a long lifetime of the clamps we also guarantee a long lifetime of the clamping jaws. At the clamping of aluminium and copper alloys the lifetime is almost unlimited. At the steel clamping of 20 HRC initial hardness the lifetime can be supposed to be in the orders of tens of thousands cycles. Using the centric jaw, the clamp can be divided into two smaller ones.
