With the continuous improvement of the status of fingerprint password lock, users have higher and higher requirements for fingerprint opening and password opening. Compared with traditional mechanical locks, smart fingerprint password locks facilitate the unlocking process of users and do not carry keys with them. What is the principle of users purchasing smart fingerprint password lock?
The principle of users purchasing smart fingerprint password lock
1, can provide more than fingerprints to open the door (because home or office is often more than one or two people), product quality must be stable, can be good;
2, can open the door with permission (it is impossible for the head of the household and nanny, cleaners have the same open management authority);
3, you can freely increase or decrease the fingerprint of opening the door (since the nanny leaves the post can easily remove her fingerprint);
4, with some password function, touch screen buttons is the trend of development, the temporary situation, the owner can use the password to open the door, the old people often or often finger contact with the rough type of work is the fingerprint crack more recommendations have a large button touch function fingerprint code lock , Such as Keyu fingerprint code lock 918 crown series.
5, must have a mechanical key, this is a way to open the door, like aircraft, brakes, although there are automatic control status, but it is not retained as part of the manual control, which is a safety consideration.
How to buy lock body?
1, because it is a combination of mechanical and electrical products, mechanical and electric drive, the clutch is very important, combined with the domestic production process, spiral spring transmission locking pin mechanism, play a solid ring of the most stable mechanism of the ring drive, those electromagnetic absorption class The market remains to be verified, because of the differences in precision and materials, some processes may not be adapted in the country.
2, choose a good lock body. The performance of the lock body, the quality is directly related to your door's flood resistance and stability. This part is also very important, fingerprint password lock is no better, and ultimately can not be separated from the cylinder part. The market always talks about the public and reasonable, and the woman is right. The best is to refer to how to choose the manufacturer, choose a good manufacturer, listen to them, qualified manufacturers will give the lock body opening and closing life, the experimental data of the handle opening and closing life, the lock body should have the lock tongue axial, Supported by lateral force data, the National Class B standard bolt has a lateral force of 3000N.
The above is about the principle of the user when buying the smart fingerprint password lock and how to buy the lock body. I hope to help everyone.

Precision Parts By Four-axis Machining
Precision parts are essential components of various machines and products that require high accuracy and reliability. The four-axis machining technology has ushered in a new era of precision manufacturing, where complex shapes and geometries can be achieved with greater efficiency and precision.
Four-axis machining involves the use of a computer numerical control (CNC) machine that has four axes of motion – X, Y, Z, and rotational axis. This advanced technology enables the machine to produce intricate and complicated parts with high precision and accuracy. Unlike the traditional three-axis machining, which can only move in three directions, the four-axis can rotate the part being machined, providing greater flexibility in terms of geometry and design.
Precision parts made using four-axis machining technology are widely used in various applications, including aerospace, medical equipment, automotive, and electronics industry. These parts are designed to meet stringent standards, making them reliable and durable. The four-axis machine can achieve tolerances as low as 0.001 inches, providing superior precision that is unmatched by manual machining.
One significant advantage of using four-axis machining technology is increased efficiency. The four-axis machine can perform multiple operations in a single cycle, reducing the time required to produce a part. This technology can also handle large volumes of parts with consistency, making it ideal for mass production.
In summary, precision parts made using four-axis machining technology offer a superior level of accuracy, reliability, and efficiency. These parts are widely used in various industries, and their high precision and accuracy make them a popular choice for critical applications. As manufacturing technology continues to evolve, we can expect more advanced techniques that will offer even greater efficiency and precision.
