A drilling machine is one of the important machine tools in the workshop. A drilling machine is used to form a hole of different sizes on a job; drilling is a metal removing process, by a drilling machine you can do drilling operation, reaming operation, and boring operation.
A drilling machine consists of many parts. iT comes in Many Shapes and sizes, from small hand-held power drills to bench mounted and finally floor-mounted models.
They can perform operations other than drilling, such as countersinking, counterboring, reaming, and tapping large or small holes. Because the drilling machines can perform all of these operations, this chapter will also cover the types of drill bits, took, and shop formulas for setting up each operation on how to drilling it.
Safety plays a critical part in any operation involving power equipment. This chapter will cover procedures for servicing, maintaining, and setting up the work, proper methods of selecting tools, and work holding devices to get the job done safely without causing damage to the equipment, yourself, or someone nearby.
Drilling Machine Types:
In the market, there are different types of drilling machines available; here, I mention some of the popular types of drilling machines.
- Sensitive Drilling Machine
- Vertical or Pillar
- Radial Arm
- Gang Type
- Numerically control
- Special Purpose Drilling Machine
Sensitive Drilling Machine:
The sensitive drilling machine has only a hand-feed mechanism for feeding the tool into the workpiece. This enables the operator to feel how the drill is cutting, and accordingly, he can control the down feed pressure.
Vertical or Pillar Drilling Machine:
Vertical or Pillar Drilling Machine is free standing and is of a far heavier construction able to take larger drills.
Radial Arm Drilling Machine:
The radial drill machine is free-standing, and the workpiece is clamped in the position on the base. It is used for heavy large and heavy work.
Gang Type Drilling Machine:
In the Gang type Drilling Machine, several spindles/ or stations are mounted on one long table as shown in the
Multi-spindle Drilling Machine:
In the Multi-spindle drilling machine, there are many spindles mounted on one head to allow many holes to be drilled simultaneously.
Numerical Control Drilling Machine:
A numerical control drilling machine can automatically change tooling with a turret or automatic tool changer. Speeds feed, and table position is controlled using a computer program.
Drills are commonly used in woodworking, metalworking, machine tool fabrication, construction, and utility projects. Specially designed versions are made for medicine, space, and miniature applications. Thus, majorly there are two Different types of drilling machines used by maintenance personnel for repairing and fabricating needed parts: hand-feed or power-feed. Other types of drilling machines, such as the radial drill press.
Numerically controlled drilling machine. Multiple spindle drilling machine, gang drilling machine, and turret drill press are all variations of the basic hand and power-feed drilling machines. They are designed for high-speed production and industrial shops. These make our life quite easy and beneficial in day to life.
