One of the most important machine tools in a workshop is the Drilling Machine. Concerning importance, it comes second after a lathe machine. Its primary design enables it to create holes on a surface. However, it can perform several other operations as well. With a driller, you can bore holes at the lowest possible costs. The rotating end of the cutting tool generates the holes on the work-piece clamped on the table. Since the device exerts upward pressure on the material, it is known as a drill press. Several kinds of drillers are available in the market, including the hand-held ones and the pillar-type.
The classification
As already mentioned, drillers are of various types. You can classify them based on their type and size. The maximum size of a drill which you can hold in your hand specifies a portable driller. The diameter of the largest work-piece that a drilling machine can operate on determines its sensitivity. A few other specifications for drillers include the maximum size of the boring tip, the diameter of the table, the speed at which the spindle rotates, and the number of speed regulators available. You can also determine the device by the Morse taper number on the axis, the weight of the machine, and the floor space you need.
The way it operates
You can create holes on a material with a twist drill or a flat drill. You can also bore in with one or multiple single-point tools or cutters which you mount on a bar or the head. You can go for reaming too, which is generally a finishing procedure. You apply this process on a hole created by the Drilling Machine, to give it a better finish. Your choice between a driller, a borer, or a reaming machine will depend on multiple factors, but the impetus will be on the size and the number of holes. For instance, if you require two components for an accurately positioned hole, you will need a single-point tool. Make sure to choose a reliable drilling machine manufacturer when buying a drilling machine.
Importance, purposes, and parts
The primary goal of a Drilling Machine is to make cylindrical holes, but it also serves a few other operations. You can use it for boring, spot facing, counter-boring, tapping, lapping, reaming, trepanning, bottoming, lapping, grinding, and much more. It is an inexpensive device which you can install almost everywhere. With this machine, you can drill accurately shaped holes and perform other operations while minimizing the costs. The main parts of a driller are the base, the rectangular table, the lever to set the table, the drill chuck, the feeding lever, the pillar, the spindle, and the main motor.
For metals and wood
A vertical driller serves its purpose in metalworking, and you can use it on relatively small work-pieces. It is the best device for individual works and small-lot production. You can see this device in the maintenance shops too. If you have to make a very deep hole, then you must use a horizontal drilling tool. You can utilize such a driller for axles, gun barrels, firearms, artillery pieces, and shafts. A center-drilling device digs holes in the ends of blanks. Some of these devices come with supports which cut off the blank before centering. For woodworks, you mostly have to resort to the single and multiple-spindle drillers, which can be one or two-sided and horizontal or vertically operating.
