cnc compression bits2/18
OK - suggestions on 3/8" compression bits especially for 3/4" thick laidup plastic laminate panels? It's that wear spot at the laminate on top of the panel. We were getting some from our sharpener and getting 50-60 sheets per but apparently he's got a new supplier and the new ones not so good.
We'd have the coated Onsrud before which cut well at first but did not after coming back from the local sharpener.
Just a note are you adjusting your feed rate after the bit is sharpened? If not, that will help also.
Ask your sharpener is they are grinding just the Diameter of the bit or the flute and diameter which is how we grind on our CNC and it makes a big difference.
Like Dan had said also, make sure your collets are good or have been changed recently. We recommend 2 times a year if you are running production.
In my experience, that is a typical number for prelam sheets. I have found the Vortex bits to be best for us, and I tried their line of "XP" bits just for running prelams. I found that the extra cost of the XP line was not justified, because the regular line of carbide bits performed nearly as well. As others have stated, expect the resharpened bits to last a bit less than new ones, and for this operation, expect less tool life altogether since the nature of the material is harder on tooling. I have tried bits with coatings from a number of different manufacturers, and found the benefits to be negligible and cost to be unjustified. This is my experience and am not endorsing or belittling any one product or manufacturer, just stating my experience for the benefit of the poster. :)
I think it is a good idea to have the manufacturer of the tool resharpen it.
If the re-sharpening process does not include a re-application of the coating, the tool will never achieve the cut quality/life of the coated original.
Diamond tooling. No personal experience, but not hard to find them.
coated definitely helps for laid up laminate sheets, but like other said, u need to find sharpener with recoating.50-60 sheets is not bad for hpl laid up sheetsgoods. bout high side of average.
Gonna put in for cnc-tool.com coated 3/8 cutter.
We cut a lot of layed up panels and we have noticed Formica brand just chewing up our bits. New or re-sharpened.
Are you using a torque wrench ? Collet replacement is imperative
As others mentioned feed rate adjustment and in my opinion send it to the mfr for sharpening. They know the tool better than anyone
Make sure when you get the cutter in you inspect it
If you are standing the panels up against a
we use Taiwan brand(but i almost sure its chines produce)Arden 6 mm up/down ,very very cheap ,can cut 120 board plywood 17 mm(4*8) and then replace
Yes, Arden is a famous Taiwan brand, you can find Arden products here
