Veidt Weighing is a Mechanical Balance factory in china. Mechanical balance is a precision weighing instrument designed based on the principle of lever balance, which has a wide range of applications in scientific experiments, industrial production, education and research fields. Compared with modern electronic scales, Mechanical balances, although relatively complex to operate, still play an irreplaceable role in many situations due to their simple structure, high stability, and easy maintenance.

Precision mechanical construction is the core feature of Mechanical balances, which mainly consists of the following parts:
Beam system: The "heart" of a balance, usually made of lightweight high-strength materials such as aluminum alloy, with an agate blade as a fulcrum in the center and weighing plates suspended at both ends.
Support system: including pillars, bases, and horizontal adjustment devices to ensure the stability of the balance during operation.
Pointer and scale: used to visually display balance status and small mass differences, high-precision scales are usually equipped with optical amplification systems.
Braking device: a mechanical structure that protects the blade from impact and is used during movement or adjustment.
Weighting system: including game codes, weights, etc., used to balance the mass of the measured object.

The mechanical balance operates based on the principle of lever balance. When the torque acting on both ends of the crossbeam is equal, the system reaches a state of equilibrium. According to their structure and purpose, Mechanical balances can be divided into various types:
Equal arm balance: The most common type, with equal arm lengths and a simple and intuitive measurement principle.
Unequal arm balance: such as analytical balance, which amplifies measurement accuracy through lever ratio.
Torque balance: measures small changes in mass using the torsional torque of elastic elements.
Spring balance: Measuring mass through the deformation of a spring, commonly used for teaching demonstrations.
Single disc balance: a modern improved model that reduces the impact of environmental factors on measurement.

Correct operation is the key to ensuring the measurement accuracy of a mechanical balance:
Preparation work: level adjustment, preheating time, and cleaning of the weighing plate are all essential.
Weighing steps: gradually approach the equilibrium point from coarse to fine adjustment to avoid using beyond the range.
Reading method: Master the technique of cursor reading and pay attention to keeping the line of sight perpendicular to the scale.
Daily maintenance: Regularly clean and lubricate key parts to avoid blade damage.
Environmental control: Keeping away from vibration sources and maintaining a constant temperature and humidity environment can significantly improve measurement stability.

In the future, Mechanical balances may be combined with sensor technology and digital display systems to develop hybrid measuring instruments that combine traditional reliability with modern convenience. However, no matter how it develops, the status of Mechanical balances as classic measuring tools and the precision mechanical design ideas they embody will always be worthy of research and reference.
