THE OLD MACHNE
THE OLD MACHNE
The project started in 2016 as home cnc router for PCB boards. At this moment it has: 2.2 kW spindle with liquid coolant, 750W servo drives for X and Y, stepper for Z axis. Top level software was developed in MVS 2012 (MFC) in the Outlook style. It provides many useful functions for operation and debug. Back-end consists of self-made AVR 32bit UC3C board. The software for the UC3C board was developed in Atmel Studio. The machine was recently tested on aluminium.

The new machine
The new machine
This is the 2nd version of my milling machine. I took into account design flaws of the previous version. The main goal is to reduce vibration to make steel processing possible. Main features: 750W Servodrives, 2.2kW Drilling unit, 4 axis controller. NC files are uploaded to the control panel using memory stick.
Mechanical design is made in SolidWorks.
The new machine has more robust design. The machine frame is much heavier and rigid. Instead of trapezoidal screws the ballscrews and linear guides are used. It has more useful options like: oil mist cooling, laser positioning. Instead of self-made PLC (Atmel) a standalone control panel CW40 is used. The controller supports up to 4 axis and has versatile remote controller for fine-tune positioning.

19/06/2019 Finally I have received aluminum parts from my Chinese friends. The quality is outstanding. Thanks to Huachaohui Precision Machinery.
21/06/2019 Z axis is almost complete. Drill clamp and the tooth holder will be mounted in the end.
25/06/2019 Working hard all nights long. XY table assembled. I expect the steel parts of the frame ready by the weekend, then few days to paint them and a week or two to assemble it all together. Hopefully the reference run will be done before my holidays.
01/07/2019 Machine frame arrived.
Total weight of the frame is more than 80kg. Thanks to my friend Peter Kihaev who made the frame.
05/07/2019 Frame painted.
It took a few days to paint the frame. I decided to use the black paint, so the grease spots and dirt will be less visible.
Few holes were made not according to my drawings, I had to redo them.
The design is too compact. Next time I will leave more space for the components to ease wiring.
11/07/2019 Main components installed.
After the main cables have been connected I adjusted the settings of the frequency converter and the servodrives.
Next to do:
- connect signal cables;
- connect limit switches;
- connect the control panel;
- connect the manual positioning wheel.
23/08/2019 First product made.
This first product milled is the cross line holder. The cross line will be installed under the spindle to make precise positioning easy.
30/08/2019 Milling alluminium.
The next product made on this machine is the alluminium legs for the frame. The total production time about 40 min for 4 legs thanks to iMachining technology.
19/10/2019 Milling cell phone shell.
Tool length wireless sensor installed. During this test 5 different tools used.
Tool length measurement tolerance: 0.05 mm.
Covers installed. Machine greased, cleaned and ready for sale.
