Beam saw vs flat table6/2/16
A beam saw will cut out shelves WAY faster than a router could.....But, any odd shapes can be cut much faster on a router...Even normal cabinet parts will go faster on a router than a beam saw and the consequent post processing on something else....
Honestly at this point, the only reason I'd recommend a beam saw/ point to point combo is if you have much edge work (Slots, edge profiles, etc.) that won't work well on a nest. BUT, if you only do that stuff once in a great while, you can even handle that on most routers with pods or jigs....Like I said, you need to provide more information.
Look at your size and volume use. Beam saw, PTP and A Bander will give you some High production and a CNC bander combo will give slightly less with more capability in custom.
Indeed....Another thing to consider is manpower...to get high volume out of the Saw/P2P/Bander combo you'll need 3 people. A well setup workcell (router & bander) can parts at a slower pace, with just 1 person.
Also....I'm guessing your from across the pond as those sheet sizes are huge by american standards. (74" x 144") You'll need to consider some material handling.
will a cnc router give cleaner cut than a beam saw?
Setup well, you'll get chip free edges off of both, but the core surface will tend to be cleaner with a saw (but acceptable on both).
If you're looking at a new bander, I'd suggest getting one with pre-mill, then it doesn't even matter what the edge looks like off the saw or router.
And what do u meen by core surface
I currently ron a nested base router and previously had a beam saw ptp combination.
thank you Derrek for your response
We cut exclusively 3/4" melamine on a pb core. We use Vortex 1/2" compression bits at 800"/ minute. We buy 20 at a time and sharpen as a group so we don't have to spend time changing for tool diameter.
and how many melamine sheet does a bit cut as average ?
Depends a lot on cutting the size of the parts excetera received 40 to 80 sheets for a bit and lose about 10% pet sharpening
thank you all for your response
I have both a pod & rail, beam saw and a nested router. Total labor time depends on how repetitive your parts are. Beam saw can stack cut heaps of parts per day. But then you have to handle them again to the P2P. The only time I would consider a P2P now would be if I was doing a lot of solid wood parts. We get about 60 - 80 sheets using the coated Onsurd 3/8" compression bits. We don't have them sharpened. Cut quality depends a lot on how good the core is on your melamine board. Too many variables to give good answers on machines. How many tool change locations do you need? How many drills, horizontals also? Do you need a C-axis & aggregates? If you use those big sheets you will need to have mechanical handling. Vacuum lifting is better than using a system that slides the panels. Sliding panels can result in scratches. If you've got the money a heavier bander with pre-mill is going to give better results than the lighter machines. If you can afford it, the "laser" or plasma machines give the best result.
It is really easy, you need both, a beam saw and a router. We run two of each.
Beam saws are great if you stack cut a lot. We plan to retire our beam saw and P2P and replace them with another router.
and what about the cutting yield how can a router with a 1.2 cm bit go vs a 4 mm blade ??
