Lathe chucks, hand operated
Horizontal stationary chuck
Special stationary clamping devices

Do you have extremely precise components that must be located on one diameter and machined on both faces? Our horizontal stationary chuck is just right for the job.

Clamping pressure is maintained

This clamping fixture, can additionally be actuated via a manual valve, has an extremely short clamping length between the machining points. The complete hydraulic system with accumulator and valve is housed in or on the clamping device. Thus, clamping pressure is maintained even when uncoupling the fixture from the clamping hydraulics.

Convincing holding power

Also convincing is the extremely high holding power offered by the fixture, which allows clamping almost without deformation at a precisely centric position. Position accuracy of 0.005 mm is attainable due to the axial draw force on the end-stop. Chips simply flow off of the chip-deflecting contour.

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.

The most important to know

• Quick change-over to I.D. clamping or 3-jaw clamping [modular system]
• 25 % higher holding power than SPANNTOP
• Significantly reduced interference contour
• Improved tool accessibility
• Ideal for limited installation space
• Lower mass
• Minimal inertia loss compared to 3-jaw chucks


Advantages

• Workpiece stabilization through axial draw force applied against the workpiece end-stop
• Prepared for inside and front end-stop
• Converts to a fully functional »bar chuck« when the end-stop plate is removed

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.

The most important to know

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.

Concentric and eccentric complete machining

Concentric and eccentric complete machining in a single clamping set-up? That’s right! With our compact chuck you can turn an eccentric position on the workpiece – in a single set-up without having to re-chuck it! Thus you save time and money.

Automatic change-over

Change-over from concentric to eccentric takes just a few seconds – it is automatic and convenient due to the setting tool in the turret and the c-axis of the machine spindle. Minimum set-up times and no machine changes whatsoever. And first and foremost: You can use your normal clamping cylinder.


Key advantages

• Infinite eccentric adjustment via the c-axis
• Concentric and eccentric machining in a single clamping set-up
• Different eccentric dimensions are possible with the same chuck
• and clamping head
• Minimal inertia loss compared to 3-jaw chucks
• Workpiece stabilization through axial draw force applied against the workpiece end-stop
• Standard clamping heads can be used

The InoFlex 4-jaw compensation Chuck is perfect if you would hook round, rectangular, misshapen geometric or deformation-sensitive work pieces. Thanks to the 4 jaw clamping technology, in which the pairs of JAWS balancing go on the Center, the workpiece is centered always to the Middle looking forward - no matter how misshapen, it is.
And also the roughing part of OP10 material tolerances are compensated. The voltage is therefore much safer and more stable than with conventional 3 - jaw chucks.

Of course, the 4-jaw compensation Chuck is also ideally suited for work pieces such as sawing sections, cast or forged parts.

The key points in brief

• ideal for the roughing part of OP10
• 4-side tension [2 x 2] with compensation of the opposing JAWS
• ideal for deformation-sensitive workpieces clamping • for indoor and outdoor voltage
• high repeatability and runout accuracy

Always use the right clamping device

With the jaw module in our HAINBUCH modular system, you are able to always use the right clamping device. More than 80 % of the workpieces are covered with the small jaw module and for large workpieces you can change-over within 2 minutes the larger jaw module.


Basic unit is a chuck or stationary chuck

Do you need a full through-bore? Do you want to implement workpiece clamping with the pull-back effect? If so, it’s all possible! Because the basic unit, into which the jaw module is inserted, is a HAINBUCH chuck or stationary chuck. If necessary, clamping heads or mandrels may also be inserted. Therefore, you always have the right solution for your clamping situation.


Always the right solution

• Jaw clamping with a HAINBUCH chuck or stationary chuck
• Enlarged clamping range of the basic clamping device
• Machining between the jaws is possible [milling or drilling]
• Deadlength clamping
• Optimum lubrication and insensitive to dirt through lubrication system
• New: more comfortable assembly mechanism

Magnet module
Clamp difficult or easily deformable workpieces

In daily use you are optimally equipped with the TOPlus or SPANNTOP chucks. However, there are always components that are difficult to clamp due to the contour, or that will be deformed through radial clamping. So what is required is an axial chuck, which in addition can also be set-up very fast.

Clamp axially on a neodymium magnet

The answer: HAINBUCH magnet module. With the magnet module you can clamp components axially on a neodymium magnet. The HAINBUCH magnet module is set-up in only 30 seconds. Your basic clamping device is already mounted. You exchange the clamping head that is included in the scope of delivery. When clamping, the magnetic clamping device is pulled onto the flat contact area of your basic clamping device.

Planar change-over accuracy of 2 μm

If, after initial installation, the magnet module is planed flat and the install position is marked, a planar change-over accuracy of 2 μm can be achieved. The workpiece itself is clamped by hand on the magnet.


Adaptation to magnetic clamping

• End face axial clamping via neodymium magnet
• High face-run change-over accuracy
• High holding force of 140 N/cm²
• Assembly in 30 seconds without aligning
• low-maintenance, resistant to contamination
