GSM2 and FlexJet heads | 10 October, 2009

I would if someone can share his "real-life" experience with FlexJet (7-spindle) heads. We are currently running machines with Flex heads (4-spindle), which are very easy to maintain, but I suppose 7-spindle has more throughput. All comments are welcome.

we have both flexjet and flexhead, we also have the new inline 7 head on some genesis dual beams we just put into operation. If you have a choice in flexjet heads take the inline 7. The flexjet 09 head is very labor intensive, stay away from them, even on what you think is a good deal. the 03 flexjet head is much better than an 09 in that the touch down sensors using the pin mirrors are much more reliable but the new inline 7 has the same touchdown setup as your old flexhead, much easier and way more reliable. we have had many instances on our 03 flexjets that the lower coupling gets damaged, even universal is unable to determine how this happens but I think that it happens when the head does a gang drop and pick of nozzles, from the changers. We also see issues with nozzles coming off in production on the 03 heads and its a real pain to find them with a loaded feeder bank! Also the newer flexjet type machines come now with only upward looking cameras, the "on the head" has lots of mirror clutch wear issues and its a pain to change clutches the way it is put together. If you buying new get the inline 7, if you going used get the 03 head and if possible get upward cameras and just remove the on the head camera,they offer a kit so you can remove it so what little speed you lose you will get back in reliability. Hope this helps.

Can you tell me how to distinguish between them? I recently bought a second GSM2. With it I've got two FlexJet heads (dismounted). The serial number of both heads starts with FJ7P, so I assume they are of FJ7 type? The issue is - it seems that the heads need a different type of cabling that I have on the machine (which has two Flex heads). At leats, that 64-pol flat cable connector has to be wired somewhere... I've tried to find some information about it in the documentation, but found nothing. Otherwise, machine is L-block. It would be nice if I would be able to get them running, but I can live with Flex heads too...

There is a retrofit kit to take care of the head cable problem that you mention. The s/n with 7P in it represents what is called the 7 Plus level of the head. There was one more level after that (09) for the GSM. The better heads mentioned in the earlier reply (FJ3 and In-Line 7) can not be used on your machine.

Thanks for the explanation - it's hard to get any information from UIC when it comes to the older equipment, so I am stucked to this forum. Can you maybe give me a hint where to ask for such conversion kit?
