Question #: 3527

Question: How small of end mills are commonly used for cutting balsa? What thickness of balsa can these smaller mills handle?

Current Solution

The size of end mills can vary to extremely tiny to very large cutting diameters. The smaller the cutting diameters, the shorter the available cutting length due to the possibility of breakage. You will first need to determine the thickness, or depth you will need to cut and find the available cut diameters for that depth.

To cut balsa wood, almost any standard 1 to 4 flute end mill will be fine that are intended to be used with wood. The end mill will state the materials that it can cut. Wood end mills will exhibit a flute geometry that is more stretched out to straight.

  • For cutting with the BlackTooth, what is the best type of clear plastic/acrylic to use, and can you recommend a source?

    The blackTooth will cut acrylic very easily. The type of acrylic (cast or extruded) is not important since the acrylic itself has 100% absorption with CO2 lasers. Any plastic retailer, even the home improvements stores will have sheets of acrylic.

    Avoid using plastics that will off-gas toxic and corrosive fumes. One example is PVC which is Polyvinyl Chloride. The burning of that material will exhaust chloride into the air and combine with the hydrogen in the air causing a chemical reaction yielding hydrochloric acid which is corrosive and highly toxic to humans.

    Always read the MSDS (Material Safety Data Sheet) for any material that you intend to burn with the CO2 laser.

  • Which end mill would you advise to buy for cutting in full depth MDF and plywood of up to 20mm thickness? I am about to install a 2.2k spindel on my cnc.
  • Please can you suggest which cutting machine is very suitable to cut vehicle tires of any thickness precisely and neat, thanks

    Any of our machines can cut or mill tire material. What you need to consider is the machine size (will the tire fit in the machine with the proper modifications to the table) and the milling tool (end mill) used to mill or cut the tire material. The end mill will need to be specifically designed to mill the volcanized rubber material and the steel belts embedded within the tire.

  • What is the Max thickness of wood that can be placed in the 4x8 cnc milling machine?

    Tricky question. That depends on the way the table is built. If the table is built with a step down area, you can put as thick a material as you want. If the table is flat, the clearance is 6 inches. Now, the thickness depends on the size end mill you insert into the collet. If you use an end mill that has a 2 inch cutting length, then your material thickness is 4 inches without a spoilboard. If you need to mill thick material, I would suggest that you fashion the table accordingly so the table can accomodate any thickness you desire. That's one of the great aspects of the buildyourcnc machines, adaptability.

  • All of the pics and videos show your cncs cutting sheet materials, I'm interested in carving 3d images in plastic and hardwood slabs up to 2" thick. What machine and software would you recommend?

    All of our CNC machines can carve at that depth without a problem and do 3d carving. Our typical application is cutting sheet materials, but a good percentage of our customers cut 3D bas reliefs or even more complex 3D objects using reference points and jigs.

    Most of our CNC machines have a Z travel of at least 6 inches for the smaller machines and 7 to 10 inches for our larger machines. The Fabricator Pro has a Z travel of 10 inches.

    Depending on your application, you will need to consider the length of the end mill (more than the deepest depth of the 3D carving) and the stock that you will be using. If the stock plus the length of the end mill exceed the clearance with the Z axis raised to the top extent, then you will need to consider the way the table/bed of the machine is formed (maybe with a depression to take advantage of the greater need for clearance).

    The greenBull has the capability of Z axis travel of up to 36 inches, but I would recommend, if milling wood, that the Z-axis not extend more than 12 inches to reduce deflection.

    Additional Information:
    Most of the CAM software on the market will have 3D profile machining operation capabilities. CAMBAM has a very nice 3D prpfiling feature. The Vectric line of software can definitely handle this as well.

  • Can a sample be sent and or brought to you for confirmation of the end results when cutting carpet tile and or hard surface tile?

  • What is the largest thickness of material that the BlackTooth can accomodate

    A standard 40W CO2 laser will cut up to 1/4" thick of material, be it wood, acrylic, card stock, leather, fabric, foam, cork, etc. (Decent speed and final cut are heavily dependent on a strong air assist upgrade)

    Metals cannot be cut due to the power level and wavelength of the CO2 laser. But it can be marked with special solutions like Cermark or Thermark.

  • What is the max thickness of material that the 80W laser can cut in plywood?

    An 80 watt laser can cut plywood up to 1/2 inch thick. Make sure to use a high pressure source of air to knock out all of the charring during the cutting process so the laser can work efficiently.

    Additional Information:
    I have a Chinese 80W laser. Just finished a cut test with 1/2" plywood. It cut through at 95% power 7-4mm/s with significant charring after two passes with no refocusing done between passes.

    Additional Information:
    That's great information. What is your PSI of the air assist on your laser? What focal lens distance do you have? And where did you place the focus of the lens (at the surface, or within the material)?

  • my end mills (router bits) are breaking during my cutting or milling process

    Broken end mills are generally a function of the end mills getting too hot, so it is a good practice to check your feedrates and depth per pass to make sure your end mill is not getting hot. After a small job, touch the end mill immediately after the spindle stops (or use a device that can measure the temperature). If it is hot to the touch, then you probably need to increase the feedrate and decrease the depth per pass. Increasing the feedrate will cause the end mill to mill new "cool" material faster, thereby keeping the end mill cool. Reducing the depth per pass will allow the end mill to acept this faster feedrate and maintain your desired edge finish.

  • LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.

    BYCNC Response:
    This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

    User Response:
    I am using the cnc planet software for your USB board. Are the limit configurations in this software?

    BYCNC Response:
    Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

  • What metal sheets can I cut with the 80W laser? What thickness, alumium, steel? What about the 100 or 130W upgrades?

    Cutting metals with a CO2 laser is nearly impossible with just the laser by itself, no matter what the power. The wavelength that a CO2 laser outputs is not best for cutting metals.

    However, if you add oxygen as a cutting assist in the cutting process, metals can be cut, but we do not advise this as it is very dangerous.

  • MY QUESTION THAT KNOW CANCER CAN BE CAUSED WHEN OUR BODY EXPOSED TO DOSES OF 50 CGY OR HIGHER. WHAT DOES STAND FOR? DO EMIT?

    The term cGy (centigray) is a unit of absorbed dose of ionizing radiation such as x rays or gamma rays. Cell phones do not emit ionizing radiation. They emit nonionizing radiation, namely radiofrequency (RF) energy. Absorption of nonionizing radiation in the body is measured in terms of the specific absorption rate (SAR) in units of watts per kilogram. Both ionizing and nonionizing radiation are forms of electromagnetic energy. The difference is that ionizing radiation has sufficient energy per photon to cause ionization of molecules. Nonionizing radiation does not. It is the ionizing effect of ionizing radiation that has been linked to increased risk of cancer. For more information on cell phones and health check out a Medical College of Wisconsin website. For more information on ionizing versus nonionizing radiation check out a University of Michigan website. Gary Zeman, ScD, CHP Lawrence Berkeley National Laboratory
