CNC machine for Modelers

Original here Modelers, because of the specificity of their hobbies, often need the services of CNC machine tools. Much easier to assemble balsa model aircraft, if its parts are cut CNC machine and going without fitting than spending days on the job with a scalpel and podshkurivat each connection. Modelers with a nick Graf and was developed by the next version of CNC machine tool - a self-made CNC machine made of wood. Download drawings CNC machine here. As a material for the manufacture of plywood taken 8 mm thick. In addition it uses 10 mm thick plywood to make the base for the axis Z (main panel). In addition to this need and a 4-millimeter plywood for the ribs, 2-parts leash on the beam and sidewall axis Z. As the lead screw used standard threaded rods, which can be found at stroyrynkah or DIY stores such as Leroy Merlin. Reducing bushes and running the nuts is better to reserve the turner and make bronze. When operating the machine wear out in the main themselves lead screws and bronze nuts running will still work after the change of the machine. Rails and a carriage for moving axes in the original design of CNC machines used on older devices. If the old equipment on hand not, you can buy such guides in the stores, "servo". For mounting rails used screws 3x10. Bearings in the CNC machine is usually not angular contact. Machine Count like a work of art - complete forms, full functionality and tidy appearance. Usually homemade CNC machine tools have a "garage" design, giblets out, done anyhow - leash would work. The second distinguishing feature of the CNC machine is the installation of stiffeners during assembly. The design is a much more robust than if we used a complex aluminum profiles. Earl wrote that the assembled machine made two sets to build the same machine. Problems with the divergence of the dimensions obtained details and repeatability have arisen. It is these edges can get a great machine rigidity with low weight. And that's rigidity allows the machine to be easily cut cutter 10 mm plywood without distorting the proportions. In the video below you can see how a homemade CNC machine with spindle Proxon cracked down on plywood. In this case, the manufacturer produced another piece to the same machine. Pay attention to the cutting speed. In 90% of video homemade mills cutting speed lower than 5-10 times. Such a self-made CNC machine can be used for cutting metal, plastic, plywood, wood, ferrous metals and fine engraving on steel mill. This homemade CNC milling machine makes it easy for making kits for assembling a model airplane (whales) from balsa and plywood. What has to work on balsa speed can be increased, because it is easy to cut Lada conventional scalpel. Make CNC Machine
