SCM K201plus Edgebander Issue10/15
When parts are fed, they hit a bar that causes the end trim to follow the panel. On shorter parts, this impact is causing the parts to twist slightly and causes two issues. Issue only occurs on parts less than about 16".
1st issue is the trailing end of the panel comes off the pressure roller so tape doesnt get pressed firmly against the panel and is sometimes loose.
2nd issue is the part is now running a little crooked through the other stations and this is effecting the quality of top/bottom trimming.
Because this is only happenning on shorter parts, we suspect the part slippage is due to insufficient clamping pressure between the track and the beam.
We have tried reducing the beam height (example, setting height to 15.5mm for 16mm material) so more pressure is applied to the panel. This doesnt seem to work.
Our next thought was that the track pads were too slippery, so we tried scuffing them a little with sandpaper. This doesnt seem to work.
Our current thought is to replace all the track pads.....but this is not cheap....so thought I would put this out here.
How long should a set of track pads last? Should a 10 year old machine that has seen light use require new pads?
Any other suggestions or anything we should be looking at?
Have you tried using mineral oil (such as that sold in drug stores) on the pads and rollers? It helped our little cehisa. We were told this by a tech.
I have not. I guess the idea is to try and soften the rubber a little?
We have tried using thinner, naphtha, and finally scuffing with sandpaper. No luck on any of those. Will give the mineral oil a try.
I had that same machine for about 6 years. Try reducing the pressure that holds up the front end trimmer. The problem is that the end trim unit is being held up in position so tightly that when the part hits the shoe the force being exerted on the part is too much to handle and the part moves in the track. You can also try lowering the beam height a bit so as to get more pressure on the part and have it stay more firmly in place.
Thanks John, but thats not it. We have that pressure reduced to as little as possible. Any lower and the saw barely stays up and wont return quick enough to trim the trailing end of the panel.
