Beam saw vs flat table

anthony Member

Hi all
hope you having a great day
i would like to ask if the cnc router flat table is able to do a good and clean job in nesting melamine boards and what is the "plus" that a cnc router gives that a beam saw cant?
and what is the more cost effective plan the cnc or the beam saw knowing that every panel is cut in a different sizes ?
hope you can help me with that i am closing a deal in the near future thank you in advance

You have not provided enough information for a valuable answer. What are you making? What other machines do you have? Do your parts require much face machining? If so, what machine to you have to process these after a beam saw?

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.

hello Gary
thank you for your response
i have a regular carpentry where i work with doors , wall panels , cabinets and i am looking to add machines to my carpentry so i can be self sufficient and will not have to always depend on others for nesting my melamine and edge bending my parts
so i am looking to get a beam saw and a cnc pod and rail and an edge bender
or on the other hand a big cnc router along with an edge bender
after this purchase i can get my own work done and other carpenters will be able to use my new machines as a service
and i can use this cnc to make my wall panels for decoration and make my key door lock hols to make the work faster
and knowing that their is competitors in my area but the only thing that this are lack is a big cnc router that can handle a full melamine board 3660mm*1880mm

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 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.

U are totlay right about the over the pond thing i work with europ made sheets
This is why i am looking at a big machine that can handle this big sheet
I would like what is the material handeling ? ( load unload tables?)

And what do u meen by core surface

I currently ron a nested base router and previously had a beam saw ptp combination.
Cut quality on cnc requires no adjustment, beam saw always fine tuning scoring blade.
Nested base very little secondary operation, beam saw always seconday operations.
Beam saw can cut a lot of parts fast, IF they are all the same size. Nested base can bore all holes needed and cut them to.size reasonably fast regardless of size.
Beam saw takes up a lot of real estate in the shop.
Unless you have parts that need extended edge drilling, i am a firm believer in nested base.

thank you Derrek for your response
i would like to add what type of bits do you use for a clean cut ?

6/6/16       #11: Beam saw vs flat table ...

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 ?

6/6/16       #14: Beam saw vs flat table ...

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 would like to know which has the least power consumption between the pod and rail & beam saw vs flat table
hope you can help me with that

6/16/16       #16: Beam saw vs flat table ...

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.

7/3/16       #18: Beam saw vs flat table ...

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 ??

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
