What is "normal" tooling style for Weinig molders

11/4/15       
scott Member

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.

Be Safe,

Dr. David Rankin

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.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    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. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    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).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
