I have an older SCMI basic 2 edge bander. I still have to do some filing, etc. Is there an edge bander that, when the panel comes out, it's 100%? What does a scraper and buffer station help accomplish? I am looking at a Holz-Her 1432 SE for 10K. Is this a good deal?
From contributor A:
I don't know if the Holz-Her is a good deal or not. I have an SCMI Selecta D. At other shops I have worked at, we had edgebanders ranging from a top-of-the-line Biesse to some POS no name thing. In all instances, everything came off finished. It is all about the operator and how well maintained the machine is. Depending on what edgebander you have now, if it is paid for, you may be able to afford some repairs. 10K probably won't buy you much of a machine unless it is a new, stripped down edgebander. The scraper and buffer are for doing 3mm and are invaluable. I have a heater on mine also, Leister, that is essentially a heat gun on steroids and heats the panel before going to the buffer station, leaving a smooth as glass edge. If you don't do 3mm or hardwood edging, a new 10K bander wouldn't be a bad thing. But 10K on a used bander will get you a lot of options. I can't find any info on the Holz-Her you asked about other than a couple of photos, but it doesn't look big enough to have all the bells and whistles. But it is all about what you need.
For a hot air machine, the Mini-Max ME-15 did a fantastic job. A very close second to the best job. The best machine was the Cheisa Pro. I think it was the 8. It ran either 24k or 32k. I know it would run shop made hardwood edgeband. It's a glue pot machine. Anyway, those two machines were far better than the rest of the machines. Noticeable quality difference of finished product. I would consider both machines to have a 100% finished edge when they came off the machines. Those were the only two.
I go to the 5 setting for pvd, to create about 420 degrees on the dial. I spray Teflon spray on all parts that the tape will touch... brass channel, finger before it, plate before it. Before doing that, the tape would often foul up after just a few boards passed through it.
P.S. You should never need to touch a piece that comes out of a well tuned bander except to put it in the rack.
Edgebanders are pretty complex machines and if not running properly, they will drive you nuts. We had bought a used Cehisa edgebander before and it was, let's say, very moody, and it drove us nuts.
Like everyone else, I'll recommend that you have it checked by a qualified tech. If you can afford a little extra or are willing to lease, I would put that money towards a new machine. You don't have to get one with a computerized interface. Also check out Felder - they have a compact edgebander which is pretty inexpensive.
Here is some food for thought. Do you want a glue pot or a cartridge machine? Our 1411 is a cartridge machine and is hot-to-trot in about 3-4 minutes. Most glue pots I've seen take a lot longer to heat up. The cartridge machines are a lot cleaner I've observed also - no stuff falling in the glue pot, dust, etc.
The edgebander is a big mechanical copy device. It copies four sides. Granted, some machines are better designed and if previously owned, some are in better condition than others.
100% finished product is possible to a point, but it takes planning and there is a cost involved to do it consistently. The operator must be a qualified person (trained) who is conscientious of his job and knows how to achieve his goal of a high quality product. It's sad to say that the industry has spent a lot more time selling the product than it has educating the market on how to properly use the product.
