The development of balancing machines has been more than a hundred years old. In 1866, the German company Siemens invented the generator. Four years later, Canadian Henry Martinson applied for a patent for balancing technology, which kicked off the balance correction industry. In 1907, Dr. Franz Lawaczek provided improved balancing techniques to Mr. Carl Schenck, who produced the first double-sided balancing machine in 1915. Until the late 1940s, all balancing processes were carried out using purely mechanical balancing equipment. The equilibrium speed of the rotor is usually taken from the resonant speed of the vibration system to maximize the amplitude. Measuring the rotor balance in this way, the measurement error is large and unsafe.
With the development of electronic technology and the popularity of rigid rotor balance theory, most of the balance equipment after the 1950s adopted electronic measurement technology. The balancing machine of the plane separation circuit technology effectively eliminates the interaction between the left and right sides of the balance workpiece. The electrical measurement system has experienced flash, wattmeter, digital, and microcomputer-based stages from the end, and finally the automatic balancing machine appeared.
As production continues to evolve, more and more parts need to be balanced, and the volume is larger. In order to improve labor productivity and improve working conditions, industrial countries have studied balance automation technology as early as the 1950s, and have successively produced semi-automatic balancing machines and dynamic balancing automatic lines. In the late 1950s, due to the needs of production development, China began to gradually study this. The development of the crankshaft automatic balancing machine was carried out, and the test prototype was made, which took the first step in the research of China's dynamic balance automation technology. In the late 1960s, China began to develop China's first CNC six-cylinder crankshaft dynamic balance automatic line, and successfully trial production in 1970. The microprocessor control technology of the balance tester is one of the development directions of the world's dynamic balance technology.
