Just remember that more flutes = higher feed speed. (which you may or may not be able to keep up with, depending on how complex your routing patterns are).
how are you mounting your tools?
Also, if you are just cutting to size, why not use a saw?
Our routing is very simple its vision panel holes in doors so mainly rectangular. Been testing a 3 flute @ 15vf this seems to be fine so will start there.
We are using mainly HSK holders
Im assuming you are machining GCC Fire Blanks 44mm & 54mm the same as us. We are using Leuco PCD Tooling 22 x 64 x Z2 (25Dia Shank) in Hydro Tool Holders.
We do Vision Panel Cutouts both 44mm & 54mm in 3 Equal Cut Depths @ 15m/min. You can do it in 2 passes happily on the 44mm but its particularly noisy on the 54mm and will only save ~5 - 10 seconds. I find the tool and machine are much happier running the 3 step cut.
I can't see Carbide tooling lasting very long doing this operation depending on the quantities and durations involved, potentially a spiral roughing tool would last depending on the finish required.
You could potentially run faster with 3 Flute tooling & Large diameter, however larger diameter is harder on the spindle and leaves the problem of correcting corner radius / square notching.
Speak to Steve Noton @ Leuco he is very good and will recommend a suitable tool (Probably PCD).
Thanks for your input mate, ive used PCD tooling at a previous company and found with chipboard i was always getting the tips replaced. Now that may have been because it was few years ago and PCD tooling was quite a new thing.
I know what you saying about STC maybe not lasting but compared to what is used at the moment it will be a massive improvement in time and replacement of cutters.
I did get a test spiral roughing cutter 18mm dia with 3 flutes and this went through 54mm in 2 hits with ease so im going to test with a 18mm 3 flute compression and see how it goes.
I think with the quality of chipboard we use the diamond cutters wont last so I'm defiantly going to use STC. We currently use leuco tooling as they are quite local to us.
After a bit of googling different spirals i think taking out about 25/28mm at a time @ 15 Vf
Yes, are your tools mostly solid carbide spirals?
I like the leitz 1/2" compression spiral for most nesting applications.
Maybe a diamond tip would be good for larger quantities. Chipboard is quite abrasive so would expect higher tool wear than with MDF
No at the moment the company is using TC throw away tipped tools which take a few passes to get thru 44mm chipboard, im looking at changing over to the STC spirals and with any luck getting thru 44/54mm chipboard in 2 passes.
Is anyone using one of these tools with their Homag machine to plunge and cut out shapes in chipboard?
We only use bearing type lock nuts now as they do give you a little better clamp tension on the tool and supposed to have a better balance. From my experience theres not a great deal difference in price so also having the option to use both rotation tools anytime in the future make them a no brainer for us.
Anyone on here using either of these? Pro's - Con's please
Thought that pretty crap really
Anyone know how I can get freeform pocketing to lead in on the fly instead of just plunging in? normal pocketing does it automatically??
All you have to do then is add several vertical trimming macros (depending on the amount of steps you want), with different Z depths.
Have a look at the file that I'll attach with this post.
Yes that is a way round it but very very long winded when we use so many different board thicknesses and other operations connected, I would have to rewrite all the my components which could take months. I still cant believe there isn't an area where you can control the tool descent like many other manufacturers SCA Biesse etc etc
yes your file works fine I think because you are going to the absolute depth but we are using milling in steps it doesn't seem to like it.
To be able to control approach and retract path speeds, you'll have to draw those paths as contours, I'm sending you a sample file to give you an idea.
Yes I tried that a few weeks ago and used the CTP but it still didn't work. Have you got something like this working at your end? could be possible something no quiet right with my system.
Thanks in advance.
That's exactly what I thought but I've tried with no luck, ive also spoken to Homag about this and they cant help.
Ok Guy's n Girl's
I'm trying to find a way to control the Z axis lowing speed for when dropping into wood using on the fly, the machine will only drop in @ the speed set for the feed. I've tried various different ways with no joy, I'm using contours not pockets.
Surely the max rotation speed is etched on the saw?
