Homemade PCB Drilling Machine


As the author decided to make a drilling machine for printing. boards, but an option such as a collet chuck in a motor circle did not suit anyone and would not suit. He needed something better and heavier in the assembly, but he did not undertake to do it from the bottom. Somehow, in a successful way, he fell under the arms of a well-worn old mini-drill, which he took as a basis for his homemade and restored.

At the beginning, the machine looked very deplorable; the author did not want to look at it, not to mention touching it. There was a spindle head with a jammed spindle, a mechanism used to move the spin (spindle) and a column with a base.

At first he had to grind a new column, because the old one was sorry for the expression was in a wretched state:

On the basis of rubber bipods or legs have been replaced and screwed, this is your right to call them:

The old m4 stop screw at the initial attempt to disconnect broke and not so weakly. He had to make a new stop. handle with bolt m6:


At first he decided to put an asynchronous 220V 6W, but then after an unsuccessful attempt the collector - 12V 12W was replaced and purchased. Attached to the SB is very simple, without any effort through the transition. plate:

A tumbler is installed on it:

He immediately took the pulley for the engine ready, so as not to bother with its manufacture:

Then he had to grind a new spindle. The time that he spent on it took the most, he had to do 6 files with a file, as he said everything turned out fine:

He pulled a pulley from hard rubber:

The mechanism for moving the spindle in a new form looks like this:

Assembly completed, result:

LED backlight will turn on in the place with the engine:

Machine after restoration:

The machine works with a bang! The author installed a collector motor to regulate the voltage rpm, but there was enough power and I did not need this idea.

Wow! It is necessary to disfigure and distort a completely normal, technically competent description! As one teacher at the military department said: "the mind is not extensible." )))
This is not a translation. But the text is of course original-))) the source is also cool, but not to that extent.
collet chuck around motor
spindle head
rubber bipod or legs, this is your right to call them
The time that he spent on it took the most, 6-h he had to do a file
collector motor for regulating the speed of voltage
etc. etc. (((
Zapadlo after auto-translation to read and correct the text? Or will it do so ?!
