Pneumatic Cylinder Draw Bar clamp/unclamp
Posted: Tue 03 Apr , 2018 15:15 pm
Hi
I have a Denford ATC Star Mill (1994) and the draw bar cylinder clamp/unclamp stroke is only 4.5mm which is not enough to release the tool holder. It has got steadily worse, but I wouldn’t know what the stroke was initially.
The part number on the cylinder is Compair Climax L.11.B VB439-C. The threaded diameter is 48mm. (see attached photo).
I have another Star Mill (identical) and that cylinder has a stroke of 10mm which is fine. The part number stamped on that is VB489-C J-17T.
Would it still be possible to source this type of cylinder?
If not, is there a re-placement cylinder which could be used?
Any help appreciated.
Kind Regards
Mark
