DIY CNC Router: Design

2223

This is the first post in a series documenting the design and build of a CNC Router. After completing the build of my first CNC router (Openbuilds OX), I wasn’t entirely happy with the performance of the machine. I decided to have a go at designing a custom machine which would better suit my expectations. After several weeks of design and analysis I came to the final design which you can see in the images above. The machine will primarily be used for cutting sheet stock; wood and aluminium.

All three axis of the machine will be ballscrew driven, dual drives on the gantry (Y axis) and single drives on the X and Z. The working envelope will be approximately 850mm x 600 mm x 140 mm.

Key components:

  • Welded steel base frame
  • THK precision linear slides 2xSSR15x760 mm, 2xSSR20x1080 mm 2xSR15x300 mm
  • Ballscrews: RM1605 (C7) – 290 mm, 790 mm, 1060 mm (x2)
  • Nema 23 425 oz-in motors (‘CNC Router Parts’ 4-Axis Kit)
  • 2.2kW water-cooled spindle
  • CNC machined 6061 aluminium plate

    Well done for your work, I’m a good machinist, I’m not very good at it
    drawing. I would like to know if you have a free version I am interested in young people who are going to drop out of school and I would like to interest them in making a cnc machine
    To show them not to drop out of school
    If possible for you
