Dynamatic Balance Machine- Milling Deweighting Balancing Machine
Overview
The balancing machine is an instrument used to determine the unbalance of the rotor. The balancing machine is a hard-supported balancing machine. The swing frame is very rigid. The measurement result of the dynamic balancing machine is used to correct the unbalance of the rotor, so that the vibration generated when the rotor rotates or acts on the vibration on the bearing is reduced to the allowable range to achieve the purpose of reducing vibration, improving performance and improving product quality.
HZ-9707A Milling Deweighting Balancing Machine,it is a fully automatic de-weighting and balancing machine that achieves the balance and correction of the work piece by de-duplication according to the design requirements of the customer's work piece. The product is milled and deduplicated. The product is suitable for the peace measurement and automatic calibration of disc parts such as brake discs, pulleys, brake hubs, clutches, flywheels, etc. This series of products generally need to be customized according to customer requirements. We will provide fully automatic products that meet customer's specified workpiece balance needs.
Application
IIt is mainly a hard-bearing balancing machine which is a combination of high-precision mechanical parts and advanced electrical parts. This series of products is a milling balancing machine developed, designed and manufactured by our company based on core technologies at home and abroad.
This product is mainly used for balance measurement and weight removal of automobile brake discs, high-speed rail brake discs, brake hubs, and water pumps.
The feature of this product is that the balance measurement of the workpiece and the milling deduplication are completed on the same equipment.
This product has high production efficiency, high precision, convenient measurement and weight removal. Equipped with different fixtures can meet the needs of multiple specifications, and is suitable for batch and single-piece production of products.
The electromechanical measurement system can be equipped with a microcomputer digital display measurement system or a computer measurement system.

Purpose
An unbalanced rotor generates a pressure on its supporting structure and the rotor itself during its rotation, and causes vibration. Therefore, the dynamic balance of the rotor is very necessary. The balancing machine is to check the dynamic balance of the rotor in the rotating state. The function of dynamic balance is:
● Improve the quality of the rotor and its components
● Reduce noise
● Reduce vibration
● Improve the trial life of supporting parts (bearings)
● Reduce user discomfort
● Reduce the power consumption of the product
Unbalance amount calculation
Where mper is the allowable unbalance:
M: represents the weight of the rotor, the unit is kg
G: represents the balance accuracy grade of the rotor, the unit is mm/s
r : represents the correction radius of the rotor, the unit is mm
n: represents the speed of the rotor, the unit is rpm.
