The machine is now cutting fast, I can start the mass production !
Some cleaning to be done …
Here is a new box for noise limitation and safety !
Build with 10 mm and 18 mm medium.
The machine stands on a plate of rubber like material designed for washing machine vibration isolation.
The blue tube is the connection to the external air compressor.
The mill in cooled and lubricated with a home-made microlub.
The oil/air mixer is based on a standard lubricating system. There is a by-pass if only air flow is required. Currently running with 3.5 bars and a oil flow of 10 drops/min.
The nozzle is based on a Locline modified according to http://www.usinages.com/supports-lubrification-eclairage-entretien/realisation-artisanale-systemes-microlubrification-t9118-60.html
The nozzle hole is 1 mm diameter. With 3.5 bars, the air flow is around 30 liters/min.
A short video showing the milling machine cutting a sheet of PVC.
After lot of tuning of my CNC mini-mill, a first real project: the remake of a broken part from a radio mast.
Step #1: an image of the broken part is done with a scanner. Then, the object is reconstructed within TurboCad V12 with a red spline.
Step #2: the toolpath is computed with Cambam CAM software
Step #3: machining on my homebrew CNC mini-mill
Step 4: the remade part with POM-C material
