What are the basic parts of drill machine?

The basic parts of a drilling machine are a base, column, drill head and spindle. The base made of cast iron may rest on a bench, pedestal or floor depending upon the design. Larger and heavy duty machines are grounded on the floor. The column is mounted vertically upon the base.

What is drilling machine and its types?

Types of Drilling Machines: Upright drilling machine. Automatic drilling machine. Multiple Spindle drilling machine. Deep hole drilling machine. Sensitive drilling machine.

What is the working principle of drilling machine?

Working Principle of Drilling Machine: When the power is given to the motor, the spindle rotates, and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion.

How is drilling machine specified?

Drilling machines are specified according to their type. A portable drilling machine is specified by the maximum diameter of the drill that it can handle. The size of the sensitive and upright drilling machines are specified by the size of the largest workpiece that can be centered under the spindle.

What are the four main types of drilling?

There are many different types or configurations of drilling machines, but most drilling machines will fall into four broad categories: upright sensitive, upright, radial, and special purpose.

What is meaning of drill machine?

Definition of drilling machine : a machine for drilling, reaming, counterboring, and tapping holes especially : a power machine for drilling holes in metal (as a drill press or radial drill)

Which motor is used in drill machine?

Universal motors can run at high speeds and are light and compact. The portable drill machine is one of the applications of the universal motor.

Is a drill AC or DC?

There are two main types of motors used in most applications: DC (or universal) motors and induction motors. DC motors are much easier to understand, so I will start with those. Universal motors are used in most hand held power tools, such as drills, routers, jigsaws and sanders.

What is drill torque?

Torque is the force the drill produces to turn an object, not how fast an object will turn. In recent years torque ratings have been steadily increasing to levels beyond what is actually needed to complete applications.

What are types of drilling?

Drilling methods

• Jetting. Sludging.
• Hand-auger. drilling.
• Percussion. drilling.
• Rotary drilling. with flush.
• Rotary. percussion.
• Hand-auger drilling. Percussion drilling.
• Sludging (reverse jetting) Method: This method has been de- veloped and used extensively in Bang- ladesh.
• Rotary drilling with flush.

Which motor is used in drill?

What kind of motor is used in electric drill?

Universal motors are used in most hand held power tools, such as drills, routers, jigsaws and sanders. I opened up one of my drills to show the insides and take out the rotor to demonstrate it.

What is a drilling machine?

Conclusion: The drilling machine is defined as a machine which is used to make a circular hole, a tool used to drill the holes of different size and other related operations using a drill bit. The drilling machine is one of the most important machines in a workshop. As regards its importance it is second only to the lathe machines.

What are the different types of drilling machine tools?

4. Drilling Machine Tools 4.1. 1. Flat or Spade Drill 4.2. 2. Straight Fluted Drill: 4.3. 3. Twist Drill 4.4. 4. Taper Shank Core Drill (three or four fluted)

What are the parts of a drilling machine?

The base of a drilling machine is generally made of cast iron or steel, and it is very rigid. At the top of the base, there are some slots provided to support the big jobs. And on one side of the base, a radial column or a pillar is situated.

What type of motor is used in a drilling machine?

In a drilling machine, we use a single-phase ac motor. Which can run at an rpm of 600-5000, or maybe more for high duty drilling machine. Pully or gears is used to transmit power and also for getting different speed. In a drilling machine, we use bevel gear to transmit power at an angle of 90 degrees.
