After the power supply of the cordless circular saw is turned on, the built-in electric motor can convert the electrical energy into mechanical energy and start running, generally using direct current or alternating current, and the power range ranges from a few hundred watts to several thousand watts. The motor transmits power to the saw blade through the belt or gear, so that it rotates rapidly, the speed can reach several thousand revolutions per minute, and the saw blade rubs against the material to be cut during the rotation process to form a cutting force, so as to realize the cutting of wood, plastic, metal and other materials.
The saw blade of the cordless electric circular saw is the core component of the electric circular saw, which is usually made of hard steel and plated with tungsten or other hard materials on the surface, different saw blades are suitable for different materials, such as wood saw blades with large tooth pitch, suitable for cutting softwood and hardwood; The tip of the metal saw blade is specially treated and used to cut metal materials. Electric motor: As a power source, many rechargeable electric circular saws now use brushless motors, which have the advantages of low noise, high efficiency and long service life. Base plate: It plays the role of supporting the saw body, usually made of metal or plastic, and is used to ensure the stability of the saw during work and ensure the accuracy of cutting.
Adjustment lever and depth adjustment device: It is more convenient to adjust the depth and angle of sawing, so as to adapt to different cutting needs and meet diverse working scenarios. Blade Guard: It is used to protect the safety of the operator, prevent the saw blade from accidentally injuring people during the cutting process, and also prevent the splashing of wood chips.
Cutting accuracy:
Many cordless circular saws support the free adjustment of the blade angle from 0-45° or even larger, combined with the precise adjustment mechanism and stable locking design, it can achieve precise cutting at various angles such as straight lines and inclined planes.
Endurance:
The application of high-performance lithium batteries makes the rechargeable electric circular saw have a long battery life, and some rechargeable electric circular saws also support fast charging technology, which can fully charge the battery in a short time, reduce the user's waiting time, and improve work efficiency. Safety design: Equipped with a variety of safety protection devices, such as anti-self-locking safety switch, which needs to be started by pressing the switch and the self-locking button at the same time, effectively preventing misoperation; There are also products with battery electronic protection devices to prevent battery overload, overheating, and deep discharge.
FAQ
Q:How long does a cordless circular saw last on a full charge?
A: The battery life depends on the battery capacity and load, generally the 20V lithium battery can be continuously cut for 30-60 minutes when fully charged, and it is recommended to have a backup battery to cope with long-term operation.
Q: How do I safely change a saw blade?
A:Turn off the power first and take out the battery, loosen the spindle nut with a special wrench, replace the saw blade of the same specification and tighten it to ensure that the installation direction of the saw blade is consistent with the identification of the fuselage.
Q: Is it normal for the battery to heat up while charging?
A: If the temperature is too high or the charging is abnormal (such as not charging), stop using it and check whether the charger and battery contacts are oxidized or damaged.
