POWER WITH BITE. THE DURO-A. FROM RÖHM. FOR WHOM Automatically clamping CNC turning centers The chucks of the DURO-A family apply up to 250 kN (in the 400-series version) clamping force to the workpiece and are thus champions in the discipline of clamping WHICH APPLICATIONS Machining of rods, tubes, flanges, washers The DURO-A is a three-jaw chuck with a force. No comparable chuck can achieve more. Thanks to the highest clamping forces, the workpieces are held securely. This enables the highest cutting performance. This saves expensive machine time. through-hole that can be clamped...

But the lubrication system on the DURO-A can do a lot more: Our ROHM engineers have designed all the grooves and bores so that the lubrication system is sealed tight when the chuck is under pressure. The advantage is obvious: No lubricant is lost. This protects the environment, saves lubricant, and guarantees that the lubricant is available when it is needed. And your service technicians will appreciate the fact that their hands stay clean when dismantling the machine.

Really for all applications. Jaws are the most direct connection to the workpiece. Therefore, they are also of particularly high priority for us. So much so that a ROHM jaw is developed and produced at ROHM. Made in Germany. And because we have been manufacturing for decades ourselves, there are also all possibilities for individual jaws at Rohm. There is hardly any jaws geometry that we haven't already manufactured for machining specialists. And if not, then we look forward to your geometry, which we have not made (yet). Customized Special jaw with exchangeable inserts for external and...

INSTALLATION MAKING THE MATCH ZA or KK The DURO-A is attached to the spindle of the machine tool via a standard connection with three screws. For an exact fit, the DURO-A is optionally available with a cylindrical mount (ISO 702-4) or a short taper mount (ISO 702-1). Do you have several machines with different spindle mounts? Then opt for the DURO-A with a center mount and use an adapter flange as well. This means that you can also mount this DURO-A on a machine with a short taper mount (DIN55027, ISO 702-1, “Attachment from the front”) or a machine with ASA B 5.9 A1/A2. At ROHM, we...

No question, with the DURO-A we have developed a power chuck that gets the best out of your machine tool. But perhaps you have requirements that can be covered better with a special solution. Maybe because you have other requirements of the geometries to be machined. Or, there are other boundary conditions due to the number of units you have to manufacture. In any case, we at ROHM have the right clamping solution. That's a promise. because you have flexible production with greatly changing part geometries. There is the DURO-A RC from ROHM for this. This automatic lathe chuck from the Duro...
