drilling operations do not differ particularly complex and often require no other equipment, except for the usual drill.Therefore, in the home workshops drilling machine may be missing.However, if you have made with their own hands tabletop drill press, you can breathe a sigh of relief, as part of your troubles resolved itself.

Sometimes there are situations when the electric hand drill, or not able to provide the desired parameters of the drilled holes.Often amateur practice need to produce printed circuit boards, where many holes should be drilled which have a small diameter.Drilled holes with a diameter of 0.5-1 mm manual or electric drill or a large drilling machine uncomfortable, and may break drill.
Buying industrial drilling machines is not always economically feasible, and then you can make a homemade drill press.Many people choose is a mini drilling machines, as, despite the apparent complexity of the design, they are actually very simple equipment and consist of four parts.
Homemade drilling machine designed for drilling through and blind holes in solid material, for example, reaming, deployment, zenkerovka, cutting discs from sheet materials and tapping.In drilling and milling machines can perform milling, surface grinding, end milling inclined and horizontal milling.
to perform the above operations using countersink, drill, tap, reamer and other tools.Using special tools and more tools, you can cut a hole with a larger diameter to bore a hole and accurately grind a hole.
drilling machines Drilling machines are these types: single- and multi-spindle semi-automatic machines, vertical boring, boring, radial drilling, horizontal boring, horizontal boring, diamond-boring.Models indicate the numbers and letters.The first digit indicates the group to which the machine is referred, the second - a kind of machine, the third and fourth - dimensions of the machine, or the size of the workpiece.
letter that stands after the first digit, it means that a certain model of the drilling machine is upgraded.If a letter is placed at the end, it must be understood that on the basis of the main model produced a different drilling machine.You can select from all the boring machines are the main varieties of universal machines: multi- and single-spindle, radial and horizontal drilling.
depending on the use, distinguish the special and universal drilling equipment.Widely adopted and specialized machines for mass production and mass industry, that are made on the basis of universal machines through their equipment and multi-spindle drilling heads change die and by automating the work cycle.
drilling machine, as well as other production machines, consists of the components: the transmission to the engine, controls and working body.Gear is designed to transmit motion from the electric motor to the working body, which is considered to be a drill that is mounted in a holder fitted on the spindle - rotating shaft.
rotation to the spindle of the electric motor is transmitted by means of belt transmission.Turn the handle and the drill chuck can be lowered or lifted using a rack and pinion.
The front panel buttons are located drill off and the motor.The device drill is simple: turn on the machine by pressing one of the buttons to extreme depending on the desired direction of rotation of the spindle, turn off the machine by pressing the red button on the middle.
machine is attached to the base of the screw-fixed vertical column.Turning the knob can be moved up or down along the screw spindle head, the second handle is used to fix it in the desired position.Controls the depth of blind holes provided through the scale.
depending on the workpiece material, require different drilling speed.To do this, it made to establish a specific spindle speed, throw on a belt pulleys of different diameters belt transmission.In the shops of the plant uses more complex circuit drilling machines than they were just considered.
principle of operation of the machine
Before drilling using a home-made machine must be removed from the desktop all the excess.Parison with the planned centers of the holes must be secured in a vise.Then insert the desired diameter of the drill bit into the chuck and fixed with a special key.To verify the correctness of the work machine includes a time.
If you have properly installed the drill rotates at its tip does not describe a circle.If it is set at a slant, and is its heartbeat, the drilling machine should be shut down and secure the drill according to the manual drill.Then turn the handle feed, lower the drill and install a vise with the workpiece in such a way as to coincide with the edge of the core drill.
Turn on the machine and drill a hole in the handle, press the feed smoothly, without much effort and jerks.When drilling through-hole, set the workpiece on a piece of wood to drill is not broke, and the machine table is not corrupted.
when drilling deep holes from time to time-out drill holes and cools it by dipping into a bowl with the coolant.Force push on the handle at the end of drilling is recommended to reduce.Drill holes and rotate the wheel feed, spindle lift to its highest position and turn off the machine.
drilling machine is easy to make your own hands.In life beneficial to have on hand tools and tools for carpentry and plumbing work.After the obsolescence of many appliances in the home side's arsenal remains a lot of useful parts and electric motors, from which you can optionally make such useful equipment such as drilling machine.
drilling machine from the drill
The simplest solution would be for you to build a mini drill with your hands using a drill.Drill bit of weight, so the rack can be made of particle board, boards or sheet metal.For comfortable work on such a machine must be homemade, so it turned out pretty massive drills to absorb vibration and quite stable.
important between the holder and the base to get the right angle.Typically, the drill is secured using two clamps (better to put between the clamp and drill a rubber gasket) to the board, which moves along the guide rails that are fixed to the board of the mobile and fixed to another board.Movement of the movable boards up and down is controlled by the associated lever.
movement of the lever down, you can restrict the bar, propped up the lever in the lower position.Fixed board is fixed to a horizontal pipe through the flange.Horizontal pipe through the square fastened to the vertical pipe that is attached through the flange to the base of the machine (to a thick wide board) or to the bench.
The height of the bar that limits the lowest position of the lever, adjust that allows you to change the depth of drilling.Take in the moving board 4 holes that are used for fixing the drill collars.On its side that faces the fixed board, glued narrow reechki who smeared wax for a better glide.Drill
apart clamps, fixed by means of two rods, which support it from below.Since such a form of mounting drills strictly vertical position does not provide drill bits, you need to stick to the board reechku compensates for this.
for free running drill guides should be prepared strictly in the vertical direction.They may be the projection of aluminum metal profiles which fasten with screws threaded to the boards along the entire length.Gathering a strong and stable structure, it is necessary to strengthen the profile of the guide is strictly perpendicular to the plane of the base and parallel to each other.
The photo made with their own hands drilling machines are clearly visible attachment points to the mobile platform drills and methods of installation guide profiles.The guide should provide high-quality mobile pressing the fixed board.The main condition in this case acts as the absence of distortions and play.
When assembling the lever, remember that you can not delay the moving parts for locking nuts made use of the second nut.Rake, which leads to the movable board of the lever, on the end to be rounded.After reducing the forces pressing for automatic lifting drill to the top position on the need to put the spring compression or stretching.
One end of the spring is fixed to a horizontal wire conduit, and a second end attached to the bottom of the movable board.When the spring is not flexible enough, and prevents the fixed board, then do it through the rope.
machine of the motor from a washing machine
drawing drill that is going through the motor of the washing machine is different from the above discussed complex mechanics and the type of drive.Asynchronous motor from an old washing machine is more weighty and has a large vibration.Shaking will be stronger, the farther from the front is the engine.
excessive vibration provokes inaccurate drilling and drill breakage.There are two ways - to make a strong frame, that when lowering the drill is lowered and the drive motor or put still closer to the front of the holder, then it will go only working part of the drill.
The second method involves a more complex design.There is needed a pulley and a belt, which can adjust the speed of rotation.There are many solutions and without a belt drive with drive placed against a wall.They are much easier to assemble, but the assembly, which will be discussed below, is characterized by non-standard approach, and some applied techniques may be useful.
Vibrations still remain, but they are so minimal that when drilling iron using a 0.7 mm drill bit, drill a whole number.At home on the high precision in the manufacture of such mechanisms can only dream of, yet it is necessary to strive for maximum fitting parts.From this will depend on the characteristics of the drilling machine and its performance.
machine movable part comprises an axial hexagon suitably sized tube, a clamping ring and two bearing and tube with inner thread for fixing the cartridge.On the hexagon part of the future of the transfer system, then puts on a pulley.The tube must first be to saw grinder along both ends, with the top nadpily make deep enough to ensure a secure grip with Allen.
Login must be made dense, drive with a hammer.If there is no putting much effort, it is necessary to choose a handset.Then fill the compression ring and bearings.Adjusting adjustment system consists of a tube with nadpilami and pinion.To make sure nadpily need to roll out clay, and it will drive the gears.
There will be a mark that is easy to measure and to make the appropriate adjustment pipe layout.The length of the ladder should correspond to the maximum height at which the drill can be raised.Allen was pressed axle bearings and the chimney with slits.
This design will go back and forth vertically in a stationary tube frame when scrolling occurs gears.Simultaneously, the horizontal axis of rotation through a belt transmission.The frame is made of metal angle by means of bolts.The entire structure is fastened to the wall.
And finally, remember that the first version of the assembly drill is preferred.The proposed second embodiment of the assembly can be completed or improved.However, such a simplified solution worthy of attention.
