A brief overview of the machine including inside the finished electrical and pump/air solenoid enclosure cabinets followed by some footage of the first part being machined. This part was cut with 12mm DOC, 1mm stepover and 1400mm/min. This was quickly realised to be too slow a feed rate as the machine didn’t seem to be […]
In part 13: – Wiring up the operators control panel – Add an upper limit switch for the Z axis – Add a pneumatic strut to support the Z – First machine movements and backlash testing _____________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling
This time I screw with my balls… This video covers the installation of the ball screws and ball nuts. ______________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much
DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much bigger mill to get the axis surfaces flat and parallel. By using aluminum tool plate (which is in theory pre-machined
In this episode I make the X Axis mounting plate for the NEMA 34 Hybrid (closed loop) stepper motor. _____________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much
In this episode I use my brother’s CNC router (that he originally built for making guitars) to machine out the Z axis motor mount and I build my own 70 volt DC power supply for the stepper motors… Transformer: Toroidal 750VA 230v AC – 24 x 24 AC output – wired in series – AirlinkTransformers.com
In this video I build the machine stand out of 60x40x3mm RHS (box) section as well as mate the X and Y axes together. ______________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building
In this video I begin wiring up the machine, mounting the limit switches and attaching the drag chain for the X axis wiring. _____________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a
This time I’m building the Z axis and mounting it to the column. I’m probably going to regret saying this, but hopefully this concludes the majority of the locating, drilling and tapping of holes. ______________________________________ DIY CNC Milling machine build. My objective for this project is to design and build a CNC milling machine without
In this video I’ll be building the enclosure around the machine. I have used 3030 aluminium extrusion to construct the frame and 4mm polycarbonate for the doors and front panel. I used a cheaper (but arguably less safe) material for the sides where people are much less likely to be stood if a cutter tries
