A planer is a remarkable tool that plays a crucial role in woodworking. It is used to create a smooth, flat surface on a piece of wood by removing excess material. This simple yet powerful tool is essential for tasks such as smoothing rough lumber, leveling uneven surfaces, or reducing the thickness of a wooden board. Traditionally, there are two types of planers, with this article focusing on the hand planer. This handheld tool requires the user to manually guide it along the piece of wood, allowing for greater precision and control. In order to fully comprehend its usage, it is crucial to understand the working principle of a hand planer. By knowing how the tool operates, its advantages, and certain precautions to take, individuals can achieve highly satisfactory results while working with wood.
A planer is a power tool that aids in smooth and flat work on rough surface materials. Let’s find out with Thptlaihoa.edu.vn what a planer is, what it is used for and how the operating principle of a hand-held planer is commonly used!
What is a planer?
A planer is an electrical device that flattens or smooths rough surfaces made of wood, stone and concrete.
This is a device commonly used in metalworking as well as mechanical processing in general, in order to shorten the user’s time of planing and smoothing the material.
Planers have many types with their own specific structures such as:
- Hand planer : Commonly used in woodworking and production work.
- Wood planer : Specialized equipment in the carpentry industry, helping to smooth and flat wood surfaces quickly and easily.
- Mini table planer : Compact design, supports flexible and faster wood planing and smoothing.
- Planing machine : Specializing in planing long wooden bars that need high flatness and straightness, processing 2 perpendicular planes, or supporting inclined planing, loose surface planing, … and small-headed wood planer.
- Roller planer : Helps the wood surfaces to be uniform in thickness, thereby optimally supporting the construction and assembly.
Applications of the planer in life
The planer marks the outstanding development of modern mechanical processing technology, especially supporting a lot in production. Therefore, the planer is widely used in life such as:
- Flatten rough surfaces or machine 2 perpendicular planes.
- Planing concave, inclined planing, planing large and small heads, etc. of the material.
- Bevel the edges of the wood and plan the end grain.
Working principle of hand planer
The motor is an important part of the hand planer, including the shaft and the wire frame:
- Shaft : Made of sturdy steel, specially shaped to be pressed against the surface of the rotor – this part is placed on two brass faces and rotates around the stator’s axis to enhance the machine’s efficiency in operation.
- Wireframe : Made of copper wire, coiled into a circle and has insulating properties. The head of the coil is attached to the commutator brass commutators, where the commutator is insulated from the mica shaft.
In general, the hand-held wood planer has the following operating principle:
After supplying power to the hand planer, turn on the switch and then pull the trigger. At this time, a closed circuit appears , the current will flow around the stator and rotor , causing the motor to rotate due to the phenomenon of thermal induction.
When the alternating current occurs, the force acting on the rotor remains constant, thereby making the motor able to rotate continuously. The motor combined with the zipper moves the blade part, so that the user can plan and smooth the material.

Hopefully the above sharing has helped you better understand what a planer is, what it is used for and how the operating principle of a hand planer is in today’s life!
In conclusion, a planer is a versatile and essential tool used in woodworking to create smooth surfaces and remove imperfections from wooden materials. It consists of a flat base or sole, a cutting blade or iron, and a method of adjustment to control the depth of cut. The working principle of a hand planer involves the manual movement of the tool across the wood, while the blade shaves off thin layers to achieve desired results.
When using a hand planer, the first thing to do is to ensure proper safety precautions are taken, such as wearing protective goggles and gloves. The wooden material should be securely held in place or clamped down to prevent movement during planing. Additionally, it is important to understand the direction of the wood grain to achieve optimal results.
To operate the hand planer, start with adjusting the blade or iron to the desired depth of cut. This can be done by either loosening or tightening the adjustment knobs on the tool. Ideally, it is recommended to start with a shallow depth of cut and gradually increase it to avoid any potential damage to the wood.
Next, hold the handle firmly and position the planer at the beginning of the wooden surface. Apply even pressure and push the planer forward, maintaining consistent movement until the entire area is planed. It is crucial to maintain a steady pace to avoid creating uneven surfaces or creating deep gouges in the wood.
Throughout the planing process, pay attention to the sound and feel of the tool. A smooth and consistent sound indicates that the blade is cutting evenly, while any irregularities may suggest adjustments are needed. It is also important to periodically check the blade for sharpness and resharpen or replace it as necessary.
In summary, understanding the concept and working principle of a hand planer is crucial for achieving desired results in woodworking. By following proper safety guidelines, adjusting the tool correctly, and maintaining steady movement, users can effortlessly transform rough wooden surfaces into smooth and flawless finishings.
