Lathe chucks, hand operated

Power chuck TOPlus

Unequalled rigidity

Up to 25 % more clamping force and higher output - with the same clamping cylinder that is used to actuate our SPANNTOP chucks. The pyramid arrangement of glide surfaces makes it possible. The clamping head rests with full-surface contact in the TOPlus chuck body - even with large workpiece tolerances.

Insensitive to dirt

In addition this geometry ensures that TOPlus is significantly less sensitive to contamination than previous chuck/clamping head solutions, and with a concentric precision of approx. 0.015 mm [for chuck size 65]! Thus TOPlus is even better suited for raw material, cast and forged parts, as well as fi ne-particle non-ferrous metals such as brass. Therefore, all-round optimized values make the chuck an ideal partner for modern manufacturing strategies and state-of-the-art machine tools.

TOPlus - simply revolutionary!

Lathe chucks, hand operated
2-jaw module
Change over from O.D. clamping to jaw clamping or centric clamping in 2 minutes - without clamping device change-over and without having to align ? No problem, with the jaw modules. Because the basic unit, into which the jaw module is inserted, is a HAINBUCH chuck or stationary chuck. If at times the clamping head reaches its limits because it must clamp a larger area, then use one of the jaw modules.

The 3-jaw module is best suited for round workpieces, and if you have cubic workpieces, then rely on the 2-jaw module. This means that for a large parts spectrum you are completely flexible and always have the solution that is ideally suited for the respective clamping situation.

Both are small, lightweight, and can be quickly changed over
- an ingenious solution for small-series production.

Power chuck SPANNTOP nova
Reliable and long life

SPANNTOP nova - this development represents more than 30 years of SPANNTOP experience. It exploits all the advantages of the latest machine tools. The components are optimized for balance quality, and have an extended guide length. The clamping length of the workpieces is also significantly greater. This chuck is designed for maximum RPM and holding power at ideal concentricity. It is extremely rigid, precise, and has an extremely long life.

Convenient change

The position-oriented base end-stop of the »combi pull-back« and »combi deadlength« variants can be conveniently changed from the outside via three clamping screws countersunk in the chuck, and for standard chucks, provides excellent accuracy for face location combined with through-bore capacity.

Chuck SPANNTOP nova: reliable and solid.
The product is the result of more than 30 years of experience!

Power chuck TOPlus mini
Lower mass

The »mini« series really shines with a mass reduced by as much as 30 %, and a chuck diameter that is reduced by 1/3. This means reduced energy consumption and better tool accessibility. Naturally, add on clamping elements can also be used with the TOPlus mini chuck. To maintain the minimal interference contour, the TOPlus mini chuck has its own adaptation devices with a smaller bolt hole circle.

Reduced interference contour

Thanks to the reduced interference contour, it is easier to choose the tool that you need. Now it can also be shorter and more stable - on the main and sub spindles. Particularly in the case of limited installation space and in series operation, the TOPlus mini chuck is ideal: Lower energy consumption, dynamic spindle acceleration, and shorter cycle times reduce the costs per workpiece.

Minimalism that pays off!

Power chuck TOPlus premium
Maximum precision in a mini format

The TOPlus premium chuck is ideal for high-precision clamping of delicate and thin-walled parts, as well as solid and massive parts. In combination with premium clamping heads and when clamping against the end-stop, you benefit from incredible run-out accuracy of ? 5 ?m.

That makes the standard TOPlus premium chuck a better and less expensive alternative to hydro-expansion and diaphragm clamping devices. In addition to high precision, the large opening stroke also facilitates automated loading of the machine - even if the robot is somewhat inaccurate. By the way, slight contact with the workpiece during loading has no negative effect on the TOPlus premium. Despite its high precision it remains »robust« and your process remains stable.

The most accurate of all HAINBUCH chucks!
