Recently, among craftsmen, the use of CNC (computer numerical control) machines for home use has become increasingly popular. At this time, almost everyone has a personal computer, desktop or laptop, which can help control the execution of highly precise and time-consuming routine jobs in the field of modeling, electronics, graphics, etc.
Why do we need a desktop DIY CNC machine?
Well, if an amateur hobbyist has a strong background in theory and experience in manufacturing precision mechanics and electronics, he can design and build an amateur machine for his own purpose. But not everyone can take on this task. To produce an inexpensive amateur machine, he needs a desktop CNC machine. For the “lazy”, a well-established, off-the-shelf machine with stepper motors would be a good option.
Applications
By using the machine as a work tool, you can:
- Drilling (manufacture of printed circuit boards);
- Mill on wood, plastics, particle board, MDF, and similar materials;
- Cut complex shapes from plywood parts (for example, in modeling);
- Engrave on all non-metallic material.
By using the machine like a pen or other pencil, you can make drawings and inscriptions on various materials and objects, including paper, film, CD and DVD drives.
When using the machine as a tool head with a diode laser, you may be able to:
- Engrave images of printed wiring on an amateur production of printed circuit boards;
- Engrave images, graphics, and labels on a variety of materials (wood, plexiglass, plastics, leather, etc.)
- Cut letters, inscriptions and drawings on self-adhesive film-type advertising on microporous materials 1-6 mm thick;
- Burn on wood, plywood photos, make family photos on fire;
- Laser engrave nameplates on plastics and metals;
- Cut non-thick materials into complex shaped parts;
Recommendation
If you need such a machine for home use, I would like to recommend DIY Desktop Triaxial CNC Machine. It is made of aluminum material, durable and solid. With the adjustable focal length, you can use it to carve wood, etc. The main purposes include wood plate engraving, laser engraving, PCB sculpture, acrylic sculpture, etc. In addition, this machine is equipped with a constant current driver board, which ensures stable optical power output. And there is no need for an external driver board. So as far as I’m concerned, this DIY Desktop Triaxial CNC Machine would be a good choice for home use.
