45º shaper tooling question1/12
I am looking for advice about tooling approaches
We have a dedicated shaper with power feeder that produces a 45º edge on plywood and lumber. Over the years we have used carbide for this but it tends to get nicks in the tooling. I would like to consider insert tooling if this would be viable with the plywood. (I am concerned about the effects of plywood glue on the steel tooling.)
The cutter head needs to be able to spin counterclockwise with the long side of the miter being on the table. (This allows us to use variable thickness material).
It must be capable of cleanly cutting 24mm thick stock (minimum).
Could this be done with an adjustable angle cutter head?
Can anybody advise me on the merits of insert tooling for something like this and can anybody recommend a vendor for this tooling?
Your existing tooling is brazed carbide? Insert carbide is typically more durable as only certain types of carbide can be used on brazed tooling. Glue lines are very abrasive and of course always hit in the same spot when running plywood. High speed steel would be far worse on the glue lines.
I would think any vendor can quote you a 45 degree insert head left or right rotation. Never used an adjustable angle head, but if it is accurate and of good quality why not!
You will be a lot happier with insert tooling. We can use a harder grade of carbide because it does not have to be brazed. This does allow for longer wear. I would think a 2 wing should be fine. I am not a big fan of adjustable angle cutters. JB, is correct, the glue lines will cause you problems. But with the insert tooling you simple change the insert and you are back running without any setup change.
I have a vari angle amana set up in exactly the way you want to use it on a dedicated shaper. We use it for our v folds. Having the long cutter edge on the bottom allows us to only have to move the powerfeed to miter different material thicknesses.
Replacing the cutters is simple. The plywood dulls cutters quickly. I would say you can run roughly 750-1,000 lineal on .75'' ply before swapping cutters. For solid wood or premium MDF it's more like 3-4000 lineal before swapping.
I would always go with insert tooling if given the choice.
