A sewing machine is a machine used to sew fabric and materials together with thread. It is an essential tool for both daily living and the clothing business. It is crucial for repairing and preserving home products like curtains and covers in addition to being utilized in the manufacture of apparel. To keep the machine in good operating order, regular maintenance is necessary. The good news is that replacing many sewing machine parts is simple and reasonably priced.
But before you begin any maintenance, it’s crucial to have a thorough understanding of the different sewing machine parts, their names, and functions, as well as diagrams for quick reference.

Parts of a Sewing Machine and their Functions
Spool Pin
The spool is nothing but a small metal rod that holds the spool thread. This spool pin is also called a spool holder. It fixes at one end, and another end tilts to a certain degree. The spool pin is to hold the spool of thread.
Its placement position can be vertical or horizontal depending upon the sewing machine brand. But a horizontal spool pin provides smoother feed.
Bobbin
The bobbin is a cylindrical spindle with a flange on both sides. This bobbin winder spindle wounds the thread in between two flanges.
It is placed in the bobbin during winding. The function of the bobbin is to provide bottom stitches while stitching.
Bobbin Winder Stopper
Bobbin has a particular capacity to store the thread. We can’t insert thread as much as we want. The bobbin winder stopper controls it.
It stops the thread from the collection when the bobbin capacity is rich to a certain level.
Stitch Width Dial
The stitch width dial controls the width between zigzag stitches. Depending on the requirement we can adjust the stitches’ width.
Pattern Selector Dial
The pattern selector dial is to select the type of pattern you want while sewing. It can be achieved by simply rotating the dial into the required pattern. There is the following pattern available in most sewing machines.
1) Straight Pattern
2) Embroidery Pattern
3) Zigzag Pattern
Handwheel
The function of the handwheel is to control the height of the needle by raising and lowering the needle. This process is done only manually with the help of hands.
In almost every sewing machine, the handwheel is on the right side.
Stitch Length Dial
A stitch-length dial is available in the automatic sewing machine. The function of the stitch length dial is to control the length of every stitch while sewing.
Reverse Stitch Lever
When we push the reverse stitch lever, sewing happens in the opposite direction. This lever is very time-saving because it will reduce the time to change the direction of fabric when sewing at one end completes. This reverse stitch lever is very helpful while zigzagging.
Power Switch
The power switch is only found in an automatic sewing machine, not in a manual sewing machine. The function of the power switch is to switch On and Off the electric supply.
Most of the time, the power switch is on the right side of the sewing machine.
Bobbin Winder Thread Guide
The function of the bobbin winder thread guide is to guide the thread. It is easy and time-saving because finding the end of the thread is very difficult.
It helps to insert this thread into the needle and prevents the thread from twisting.
Thread Tension Dial
As we know, tension is important while sewing. If we keep low tension on the cloth, then stitches do not become proper and create more difficulties while sewing.
If the tension on the cloth is high, then the distance between each stitch becomes more. Hence strength in stitches becomes less.
So, to avoid such trouble, the thread tension dial helps to adjust and control the tension by simply tightening and loosening.
Thread Take-Up Lever
The thread take-up lever is above the presser foot of the machine. Its function is to pull the thread from the spool and feed it to the sewing machine.
It helps to lift the thread when the stitches are complete. The thread take-up lever moves up and down as the needle moves.
Needle Clamp Screw
As we know, the needle will not stand in any place. So, to keep the needle in the same place, we use a needle clamp screw to tighten the screw to fit the needle in one position and not move anywhere.
Presser Foot
Presser’s foot is to press and hold the fabric in position just below the feed dog. Another function of the presser foot is to give stability while sewing.
It also helps to prevent wrinkles while sewing. Many types of presser feet come in marker. Zipper, satin, button stitch, and overedge foot are the typical and most used presser feet in the market.
Bobbin Cover
Bopping cover is a steel plate that acts as a coverall for the bobbin. It protects the bobbin from dust and debris particles.
Bobbin Cover Release Button
It is a button used to remove the bobbin cover by pressing the bobbin cover release button and remove the bobbin cover and access the bobbin.
Feed Dog
The function of the feed dog is to move the fabric in forwarding and backward positions depending upon the requirement.
It is usually visible to our eye because it is on the needle plate. We need to change that feed dog and place a new one if it damages.
Needle
The needle is helping to give stitches in the fabric that we have sewed. Different types of needles are available depending on the type of fabric. These needles are easily removable and clamped in a needle clamp.
Needle Plate
A needle plate is a metal plate that is available below the needle and presser foot. The function of the needle plate is to move the fabric in a forward position while sewing.
