This material is required to build a 25T trolley that will be moving a manipulator up and down a 100m track. We're really looking for mass rather than strength due to the fabrication of the rest of the structure. This material was previously supplied by Corrus here in the UK but they have since...
Sorry I haven't been in touch, I've been in Germany on a different job.
Thanks for your replies, we haven't yet checked the drawbar strength, I will talk with my bosses and get the OTT tool for my next trip out. We have been given a recomendation of 25kN from OTT.
I will post the results as soon...
We manufacture large grinding and cutting equipment. Recently we produced a grinder with an automatic tool changing system but have been experiencing problems with the tools sticking in the taper. We are using a SKF 50 style taper and an OTT Jacob clamp/push cylinder for holding/ejecting the...

For those of you intrested in the actual control system needed for these systems there is a good article on the Danaher website:

We are finalising the supplier list at the moment and gathering quotes. It is more than...
As a follow up if anyone is still watching this thread.
We have found two companies who have implemented this system: NUM-Schneider and SEW Eurodrive, applied mainly to large CNC machinery.
Initial figures for the motors show that in single-direction motor movement we need a little over 100NM...
On another note Servocam, I'll probably see your UK counterparts in a week or so at the Drive and Controls Exhibition in England. Do you guys do a lot of business in Europe?
The only problem with using the external feedback encoder (ie. not on the motor shaft) is if there is a lot of backlash the controller can "hunt" for position. The controller will continually oscillate back and forth through the backlash producing a very unstable machine. As the rotary...
What I wanted to hear to be honset :)
I'll grab a Demo of Concept, strange that Schneider are usually quite reasonable when it comes to software costs, Siemens are usually the ones charging through the nose.
Thanks
Has anyone used Modicon Premium or Quantum PLC/Motion controllers? On paper they will do the job we require but having only used Siemens and Indramat in the past I am not sure about the ease of use, flexibility or reliability of the Modicon range.
How does their programming environment compare...
Thanks for the response!
The Dual Motor system came from my boss who has used them in the past. The controller that he used previously meant that the combined power of the motors was equal to running torque required. Indramat and Siemens systems on offer today do not support this configuration...
We are building a high inertia robot that requires very high precision on several rotary axis. We need a a system to negate the backlash and have decided that Back To Back motors would be best. Because one motor is "dragging" on the other Indramat and Siemens solutions only allow one...
If you can't find a local distributor check here:
http://mall.ad.siemens.com
You can buy direct from there or it is possible to find lists of local suppliers.
