Hello everyone,
How have you been going with winding angle selection? I understand the 90’ is optimal for burst strength (which many of you will use for rocketry), but I am generally trying to optimise bending stiffness. I started…
Read more…Hello everyone,
I'm excited to finally have our machine up and running and winding mandrels, but would really love to hear guys experiences in the resin ratio / viscosity used, and how to control the layer…
Read more…So, after producing 15 or so poles on my x winder I was wondering what everyone has been using for their mandrels? So far it looks like cardboard is popular, but I imagine this would be too inconsistent for my parts. I have read that mandrels…
Read more…Hi, I am a new user so this may have a simple fix that I am not aware of.
I am trying to create a 45-degree 2-axis layup in 3-axis mode. The 4-axis winder that I am working with has been having an issue where the dwell times are…
Read more…Hi guys, we just got our X-Winder (Prague) and have the same issue as many - tow is slipping at the ends of mandrel even with maximum rotation of 230 degrees. We were thinking of adding plate of same diameter as mandrel with pins at both ends of…
Read more…is there a calualtion or table where is can figure out the thickenss of different degree completed layers. like i have incountered that 12k tow at 75 degrees is .48-.55 mm for a completed single layer. this would be really helpful when trying to…
Read more…Hello All!
I have a custom machine, 105 IN carriage.
Mandrel is 6:1
Carriage uses T2,5 mm teeth 1º pulley 20 to 2º pulley 60 teeth.
My problem is that 4.2 seems not posible to configure carriage out of standard gearing…
Read more…Hello everyone, Great to be part of this forum for this machine, already thinking about how I can redesign the squeeze without even winding yet.
I have been having extensive trouble and been trying to get my 4-axis X-winder up and…
if I'm wrapping a oval shaped mandrel thats about 80mm by 30mm what do i set at the mandrel size in the software? 80mm? or do i have to calculate the circumference?
Read more…I also made this roller with teflon stock. It's kept in place with two aluminum angles with pins as axle so it rolls…
Read more…when i begin my winding (2x) the carriage will go to the limit switch and then begin the next process but when it comes back it will hit the limit switch hard and just bang against it. i have tried messing with the z offset value but it keeps…
