Chuck clamping - Import export

Application The SG 175 support grinder is designed for grinding the conical seating surface of valves of medium speed diesel engines on a standard lathe. Handling The support grinder is clamped in the toolpost located on the top slide of the lathe. The grinding angle corresponding to the required valve seat angle is adjusted by turning the top slide of the lathe to an angular position which corresponds to the valve seat angle and which is defined by the template supplied with the grinder. The valve stem is clamped in the chuck of the lathe and the valve face is ground by feeding the grinding wheel into the rotating valve face. Features The precision grinding spindle is permanetly sealed and lubricated for lifetime accuracy. The wheel guarding system is designed to the prevailing safety regulations. The cone-shaped head of the template is provided with a bore receiving the dressing diamond so that the grinding wheel can be properly dressed after adjustment of the grinding angle.

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.

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!

With our hexagonal clamping heads you get up to 25 % more clamping force and higher output with the same clamping cylinder actuating force that is used to actuate our SPANNTOP chucks. The pyramid arrangement of glide surfaces makes it possible. In addition the hexagonal geometry ensures that TOPlus is more resistant to contamination than former clamping head / chuck systems. Therefore, TOPlus is even better suited for raw material, cast and forged parts, as well as fine-particle non-ferrous metals such as brass. With a concentric precision of ≤ 0.005 mm!

Large workpieces – large chucks – large clamping heads. So far so good, but sometimes you also have to machine smaller workpieces? Instead of buying large clamping heads with a small diameter, there is now a better alternative: the clamping head adapter. For example, it can basically turn a size 100 chuck into a size 65 chuck and you can then change your normal size 65 heads using this clamping head adapter. Your advantages are in-stock availability and a lower price for the smaller clamping heads. You also save the costs of purchasing new large clamping heads if you are already using smaller clamping heads. Changing the clamping head adapter is fast and easy with the suitable changer interface.

4-jaw clamping device InoFlex VF — ideal for the raw parts milling machining OP10 — 4-sided clamping with compensation of the opposing jaws and 2-sided clamping possible as a stationary chuck or centric clamping vice — ideal for clamping workpieces sensitive to deformation — for I.D. & O.D. clamping — high repeatability & run-out accuracy

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!

Easy manual actuation The TOROK manual chuck is primarily used in tool prototyping on machines without a clamping cylinder. For example, thanks to its easy manual actuation, when used on grinding machines you can safely and delicately clamp. In combination with our clamping device adaptations, such as the MANDO Adapt mandrel-in-chuck or the jaw module, many more clamping options are possible. Lightweight variant And most recent: Thanks to the optional lightweight CFRP design, with the TOROK CFK you save one-third the weight. This is particularly set-up friendly and it offloads the machine spindle bearings.

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 μm. 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!

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.

Flexibility thanks the modular system I.D., O.D. or jaw clamping – it‘s easy with the B-Top3 modular system. Everything fits together. With MANDO Adapt segmented mandrel, you can change to perfect I.D. clamping in less than 2 minutes. The SPANNTOP adaptation is the right partner if you have reached your holding power and accuracy limits for O.D. clamping. And all without removing the chuck!
