My story of the construction of CNC machine with their own hands
Greetings to all residents of Geektimes! Today I want to tell you my story of the construction of a budget classic portal milling machine.
I want to start with a story that began in late 2015. Having met my friend then, he suggested that I make a CNC milling machine for cutting plywood and plastic. Without thinking twice, I told him that for cutting out various words, frames and other things, the machine would not pay for itself and become unprofitable, to which he replied to me "think of something" ...
Since the project was based on interest, I, of course, took it. But everything would be fine, but there was no money for the proposed project, and there was no free time either. Then, based on the tasks assigned to the machine, the following was designed:
')
As a result, 20 tr were allocated to the whole machine. Working field - 550x950 mm. As a control, I chose the Chinese blue board on the TB6560 drivers on 4 axes, the kit also includes 4 engines, a power supply unit, a CD with software and a wire for connecting to a PC, at that time it cost me 14 kopecks etc.
Since it was planned to do something like a designer, and without resorting to milling, boring, grinding works, the entire structure was made of 8 mm thick structural steel, cut on a laser CNC machine tool. But turning was not without turning, as it is necessary to sharpen the bearings, sleeves, slip, grind the ends of the screws and this helped our subsidiary. In general, with regard to metalworking in Russia, I tried to express my thoughts in a blog so as not to flood here.
Bearing support.
As a result, the cutting of all parts to the machine from a metal sheet came out in 1.5 tons., Another 2 tons. I gave for turning, the rest was spent on fasteners, bearings and other moments that were not certain to me.
Next, I would like to show a few videos about the assembly process and the operation of the machine, as well as a photo of what I tried to cut.
And one more thing: I decided to use an ordinary drill as a spindle, due to the low speed of the machine.
Tried to burn
According to the results of the assembly of the setup and verification, it can be said that the machine turned out to be workable, but quite “liquid”, but this was understandable in the budgeted budget. And he performed his tasks perfectly ... The machine was assembled by the end of February and paid off from a friend before the summer, after which he successfully sold it for 30 tr. Sold for a reason - tired, lost interest, and unwillingness to work.
I may have missed something and did not describe it, I hope that there is all the missing information on the video. In the other case, leave comments.
