A compact drill press is a must in a home lab. If you are engaged in the construction of various kinds of devices, then the acquisition of such a machine becomes a necessity. But you can always make a drilling machine with your own hands, it is much more interesting and cheaper. Moreover, this does not require scarce materials, this task is within the power of each of us. The main thing is to decide for what purposes you will use this device and what power is ultimately needed for the machine to work.
If you are a radio amateur, then for drilling holes in
printed circuit boards it is quite possible to use a small-sized home-made drilling machine of small power. It consists of an engine with a cartridge, which can be purchased at a specialized store. It is proposed to use the FZF frame here as the moving part. Such devices were designed for macro photography and now they are no longer needed. If there are parts, making a small drilling machine with your own hands will not be difficult and will not take much time. You will also need a small piece of organic glass or textolite.
We begin the assembly. First, we cut out organic glass or textolite in size and fasten it to the base of the future machine.
Next, prepare the hole for mounting the engine and install it. Now we organize the power supply of the electric motor, assemble the circuit through a small switch. Motors of this power can be powered by DC voltage, which means that you need a power supply. Everything, you have assembled a home-made compact drilling machine with your own hands. Before starting for the first time, be sure to check the ohmic resistance of the motor and the integrity of the switch. The position of the electric motor is adjustable
screw on the right.
If you want to assemble a drilling machine with your own hands of greater power, then to implement this idea you will need a powerful electric motor powered by a household network. An electric drill may be an ideal option in this case, moreover, there is no need to search for a cartridge for drills. The main difficulty will be the design of the mobile base. This problem is solved using a lifting table or a base from a vice. Of course, you can use the mobile support on which the drill is mounted, but in this case you will have to deal with the vibration that will necessarily occur during the operation of the machine.
Securely drill on a vertical base with mounting brackets. It is best to use two or more mounts. Turn on the drill and at maximum speed under load, check its operation for vibration. Then mount the mobile horizontal base. To make a bench drilling machine, it does not take much time, the main thing is to carefully assemble all the main parts of the product. Such a device is quite suitable for performing carpentry work, in addition, it can cope with the drilling of miniature holes for printed circuit boards or homemade products.
