What kind of a machine for a small wooden part

2/8/22       
Arto

I have been manufacturing a wooden part, roughly 70mm long, 65x35mm.

The grain goes in the 70mm direction.

It is like an oval, with holes drilled through it to the direction of the grain.
I am currently making these on a normal homag cnc, with a jig that holds a 900mm piece of wood vertically (from floor to the work area). When the piece is done with the outside shape and holes, its cut of. Than i rise the piece of material and start over.

I would like to have a machine, that vertically feeds a longer piece of lumber, and has vertical spindles for the operations. Seems like the best way in my opinion to do it. Kind of like a metal lathe with live tools and a bar feeder. Just i dont need the lathe here, just a feed and horizontal tools.

Buying another huge machine for these small parts seems kinda dumb. Would prefer something more suited for this kind of work.
Kinda like a cnc tenoner with more tools and automatic feed.

Anyone know any machine like i describe here?

Maybe look into farming it out to a production mill-turn shop that can turn/re-fixture very quickly. Sometimes farming out work to a specialized shop is more profitable than the work of brining in a machine for single op.

Why not cut your blanks first to rough thickness. Build fixtures to hold several on the cnc. You would get a more efficient work flow and you could break the machining into two zones where an operator can be loading one zone while the machine is working the other.
Vertical feeding is bound to be inaccurate and limited to one at a time machining.

Tom:
That is what i do at the moment. A machine working the way i describe would not tie the ooerator so much.

Mark: Do you know which brand machines those kind of shops would use?

This post reminded me of something I'd seen on Instagram a while back. Not US based, but this could certainly make the part that you're referencing. (link below)

I assume you have some kind of vise that is holding the 900mm piece.

Can you turn vacuum on and off with M codes?

I would use pneumatic or air vise control by an M code somehow. May need to get creative but I'm sure there is a way.

Nest make a tool that will slightly grip the 35mm by 65mm end of the blank.

When the first part is finished, load your super custom gripper tool.

Spindle speed zero.

Drop the spindle down until your super tool grabs the top of the blank.

Use M code to open the vise

Move Z axis up 70mm plus 2 or 3mm so you can kiss the top for accurate length.

Use M code to clamp blank.

Raise Z axis off the blank.

Face top of blank and cut part.

Repeat until 900mm used up.

You could just bolt a gripper to the gantry somewhere with the appropriate offsets and not use the spindle.

If you don't understand what I am talking about google bar puller cnc lathe and you'll figure it out.

  • 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.
