A place where hand tools and power – driven tools are used for making,
finishing, or repairing machines or machine parts.
Machine Shop
Is the process of forming and shaping metals to create useful tools, objects,
equipment parts, and structures.
Metal Working
Is a process where pieces of sheet metal are modified to its geometry
rather than removing any materials.
Sheet Metal
Is a process used to form cylindrical parts by rotating a piece of sheet metal
while forces are applied to one side.
Spinning
Is a form of machining, a material process, which is used to create
rotational parts by cutting away unwanted material.
Turning
Is used to produce square holes, keyways, spline holes, etc.
Broaching
is a device used to measure the dimensions of an object.
Caliper
Are standard tools in an auto-garage or workshop, and they come in handy
in measuring the internal distance of objects.
Inside Caliper
Is also known as the hermaphrodite or odd leg caliper is a unique
instrument due to its features.
Jenny Caliper
is the resistance of an object to a force that could tear it apart

Broaching machine
is a machine tool that is used
to remove metals from a workpiece to give a
desired shape and size.
Lathe Machine
is the most widely used lathe
machine and still, it is, in every workshop, this machine is present.
Center or Engine Lathe Machine
is also called a Wood Lathe. As the name indicates “Speed” the machine works with high speed.
Speed lathe
This is an advanced technology of the manufacturing industry.
The capstan and turret lathe machine is used for Mass production (large Quantity) and is a
modified version of the engine lathe machine.
Capstan and Turret Lathe:
It is mainly used in grindings, working on the tool, die gauges, and machining work where accuracy
is needed.
Tool Room Lathe:
This type of lathe machine is small in size and use for very small precision work. It has all the
similar parts of engine lathe and speed lathe.
Bench Lathe:
performs work automatically. Standard lathes have some drawbacks i.e. they are not used for mass production. But this
lathes are used for mass production. Some mechanisms are responsible for the automation in it.
Automatic Lathe
the machine performs the special types of operation
which can not be performed on standard and other machines.
Special Purpose Lathe
stands for Computerized numerically controlled. This is widely used as a lathe in the present time because of its fast and accurate working. It is one
of the most advanced types.
CNC Lathe Machine
A Lathe Machine consists of the following operation: (Give atleast 5)
Centering
Facing
Turning
Chamfering
Knurling
Thread cutting
Drilling
Boring
Reaming
Spinning
Tapping
Parting off
Uses of the Ball Peen Hammer?
-The ball peen hammer was made for use in striking and shaping
metal materials
Importance of Ballpeen hammer
Driving cold chisels
The steel ball peen head is hardened and is less likely than a
claw hammer’s to chip, making it better suited to drive punches
and cold chisels, set rivets, and shape metal.
Ball-peen Hammer
A cross-peen hammer has the
wedge end of the head (the peen)
angled horizontally relative to
the handle.
Cross-peen Hammer
A straight peen or straight pein
hammer has the wedge shape of the
peen running vertically, parallel to
the line of the handle.
Straight Peen Hammer
They are also
particularly used in riveting.
Straight Peen Hammer
are handy tools for numerous jobs around the home, from installing large picture hangers to making furniture.
Power drills
is used to cut holes into or through metal, wood, or other materials. The drilling machine or drilling press is commonly used in the engineering field.
drilling machine/drill press
The operation of making holes on the surface of the workpiece by the use of drill bit
Drilling Operation
The operation of sizing and finishing an existing hole with the help of a reamer
Reaming Operation
It is the operation of creating internal threads by means of a cutting tool
Tapping Operation
The operation of enlarging an existing hole
Boring Operation
is a method used to create an even surface on the inside wall of pipe end.
Counter-boring Operation
is a process for the post-processing of existing drilled holes.
Countersinking Operation
This is an operation of removing the chips from the surface of the hole such that proper seating of bolts takes place and this removal can be done through end mill cutter using a drilling machine.
Spot Facing Operation
Without drilling, a _____________ is used for producing a large-size hole of more than 50mm in diameter
Trepanning Operation
In this operation, the tool will rotate and reciprocate about its axis for producing very smooth holes
Honing Operation
Types of Drilling Tools
- Hand Drill
- Standard Electric Drill
- Hammer Drill
Types of Drilling Bits
Twist Bits Masonry Bits Dowel Bits Flat Bits Augers Bits
is the most basic type of drill. They’re great for pre-drilling holes before inserting screws
Hand Drill
These drills are ideal for the majority of repair operations
Standard Electric Drill
are comparable to conventional drills, but they have a “hammering” aspect as well.
Hammer Drill
These are the most commonly utilized bits
Twist Bits
These are great for hammering bricks, stones, and mortar, but they should always be used with the hammering on.
Masonry Bits
The cutting edges of these bits are usually in the opposite direction, and they always have a sharp tip.
Dowel Bits
are a relatively old form of drill bit that can be utilized effectively in a variety of applications.
Flat Bits
These are high-torque, low-speed bits. They save electricity and make extremely clean holes.
Augers Bits
Types of drilling machines
Portable Drilling Machine Sensitive Drilling Machine Upright Drilling Machine Radial Drilling Machine Gang Drilling Machine Multi-Spindle Drilling Machine Automatic Drilling Machine Deep-Hole Drilling Machine
are commonly used in all the workshops. Used to drill small sized holes
Portable Drilling Machine
Used to drill small holes at high speed in lighter jobs.
Sensitive Drilling Machine
It is larger in size and stronger than sensitive drilling machine.
Upright Drilling Machine
is an industrial product and specially designed and manufactured for large and heavy work items.
Radial Drilling Machine
This type of machine tool is used to drill a large number of holes in the same job at a faster rate.
Gang Drilling Machine
It is used to drill the number of holes in the same workpiece simultaneously and to reproduce the same work in a number of similar jobs.
Multi-Spindle Drilling Machine
that can perform a series of machining operations at successive units and transfer the work from one unit to the other automatically.
Automatic Drilling Machine
This may be the either horizontal or vertical type of machine. In this drilling machine, the part to be drilled is rotated and the drill bit that makes the hole is kept stationary
Deep-Hole Drilling Machine
is a machine tool equipped with an abrasive wheel used for producing fine finishes or making light cuts on metals and other materials.
GRINDING MACHINE
TYPES OF GRINDING MACHINES
Bench Type Grinding Machine Portable Grinder Pedestal Grinder Flexible Grinder Precision Grinding Plundge Cut Grinder Form Grinder Internal Grinder Centerless Grinder Surface Grinder
is a grinding equipment that uses abrasive wheels to drive things.
Bench Type Grinding Machine

Flexible Grinder
is a manufacturing technique that is used to fabricate and finish metal products with extremely tight tolerances.
Precision Grinding
These are also called crankshaft grinding machines
Plundge Cut Grinder
These wheels are given feed and accurate grinding is done as per the shape of the grinding wheel on the moving cylindrical surface
Form Grinder
These grinders are used for grinding round and hollow jobs whether the internal surface of these job is completely round, ditched round, or is in taper.
Internal Grinder
is used in modern workshops for mass production. Jobs of glass, porcelain, wood, rubber, plastic, iron and steel and alloy are polished and finished with this grinder.
Centerless Grinder
