What is "normal" tooling style for Weinig molders11/4
We are waiting for our used Weinig Profimat 23 5 head molder and used Rondamat 925 to arrive. We plan to have a molder guru come and train us on our machines (probably early December, maybe late November) but right now while waiting I am trying to learn about the world of Weinig molders and begin to form our tooling strategy. We are moving from a Wm & Hussey which has been a faithful tool for over a decade to a "big boy planer" and have a lot to learn. A few general tooling questions:
1. What is the “normal” kind of knife run on Weinig molders in general –
a. is it HSS corrugated knives ground by the woodwork factory itself on a Rondamat or equivalent? From looking at Weinig USA online tooling catalog it seems corrugated knives are “normal”.
b. Is it welded carbide knives custom ordered from tooling companies like those commonly used on shapers? How often are these welded “shaper” cutters used on Weinig molders?
c. Is it solid carbide insert tooling like Leitz, Vortex, Garniga, Leuco, etc?
d. When would I choose one of these over the other options? I am planning to use insert tooling for flooring and cabinet and passage door sticking profiles that have precision mating profiles – I’d be afraid to try to have our guys consistently grind these accurately.
2. These two profiles shown below – what kind of knife do you recommend for the 127mm crown and the 70mm door casing? We run these often, but in small quantities. 100% of our production is for a single home or project at a time made to order. So a typical run on the molder might be anywhere from 5 to 200 meters of stock on a given profile, and always in hardwoods such as walnut, cherry, oak or alder.
Especially interested in response from people who have Weinigs or are very familiar with them.
Corrugated knifes are the most common type of tool for in house grinding. The use of carbide inserts is also very common.
The brazed on tools are still used on moulders but are not as common as the corrugated version.
I use the carbide insert tooling for the straight tools and sometimes for the angle cuts. The profile tools I recommend either M2 steel unless the rums are long or out of maple, then I recommend DGK knife steel.

I went through the same thing your going through about seven years ago. I have a Weinig Unimat 23 and a R934 grinder. It took a little while to work everything out but we now run around 150,000' through it a year. I run a spiral insert head on my first head for "hogging" off the excess wood. The rest of the heads are corragated M3 HSS. We run anything from shoe mould to 8" crown. I've tried Terminus straight knife heads but it is easier and cheaper to grind your own straight knives, at least in my opinion. The biggest learning curve for me was learning the grinding process. I happened upon Jim at Alliance Knife Grinding and actually visited him at his shop. He gave me a crash coarse on grinding and that was a huge help. I still get all my grinding supplies from him and he is awesome. Hope this helps a little, if you ever want to talk shoot me your number.
Congratulations on your purchase of your Weinig Moulder. Weinig can supply you tooling for all of current an future tooling applications, as well as diagnostic support an etc. I specialized in special tooling applications for Michael Weinig, such as corrugated tooling both HSS/Carbide, custom insert tooling & outside tooling sales. Please do not hesitate to give me call or email at your earliest convenience. Please message for contact info. I look forward to helping in anyway I can.
