Spindle arrangement is present at top of the column opposite to the arrangement of the motor. The basic function of the stepped pulley is to control the speed of the rotation of the motor. Out of these two, one pulley will be in an upward direction while the other pulley is inverted.Īlways both the pulleys will be there in the opposite direction. Two steeped pulleys are present on either side of the column at the top. The inside motor shaft is there which is connected to a stepped pulley so that we can increase or decrease the speed of the rotation of the motor. The motor is present at the top of the column. A table can be adjusted at any angle as per the requirement. The table is attached to the column and it can be rotated around the column and can have an upward and downward moment. The table is the place where the workpiece is being mounted. The pillar helps the motor and the spindle head. A pillar is present at the center of the bed. The pillar is a type of vertical column that rests on the bed. The bed is made up of cast iron, so it has high compressive strength and good wear resistance. The bed is the main part of the machine on which the whole machine is being mounted. To perform boring action by a machine a special holder for the boring tool is required. Basically, Boring is a process in which the holes are enlarged that are already being drilled or cored. In the lathe machine, the workpiece rotates and the drilling tool is held stationary in the tailstock.īoring: When we talk about drilling, boring is mostly discussed. Drilling operations can also be performed on Lathe machines. Drilling Machine Definition:Ī drilling machine is a type of machine in which the holes are being made on the workpiece by making use of a rotating tool called drill bit or the twist drill.ĭrilling is basically a technology of creating holes. Now the electric drills are available in a variety of sizes and forms. Present-day electric drills have gone a long way. Inventor: Close to the end of the 18 th century Arthur James Arnot and William Blanch’s brain invented the electric drill machine. Bow drill was used for woodwork, stonework, and dentistry. Similarly, in the past, the Homo sapiens used a rock with pointed edges which they use to spin in between their fingers, and with the other hand, they would hit it so as to create a hole.Īs time passed developments were done on the drilling and the BowDrill is considered as the first drilling machine. Drilling Machine History:ĭrilling is a technology used a long time back in our past. It basically means to create a hole by making use of a tool. Drilling is basically a single-purpose machine tool as its main purpose is to make holes in the workpiece.Ī machine consists of a spindle that provides rotary motion to the drilling tool, which finally makes the hole in the job (workpiece).
