Fast tool servo machining refers to the fast tool servo micro-feed mechanism installed on the Z axis to drive the tool for high-frequency response, small amplitude axial rapid feed movement during the turning process, coordinating with high-precision return axis and radial feed to complete this turning process. Compared with the feed frequency of the Z axis which is generally tens of Hz, the feed frequency of the fast tool servo micro-feed mechanism can reach several kilohertz or even higher, which greatly improves the processing efficiency.
Compared with other ultra-precision processing methods, the fast tool servo turning processing technology has the characteristics of high frequency response and high efficiency. It can obtain complex microstructure surfaces with high surface accuracy in one processing, which is suitable for high efficiency and high quality of microstructure components such as optical components processing
Fast tool servo turning processing requires high-frequency response and high-precision micro-feed. At present, the driving mode of the micro-feed mechanism is mainly driven by piezoelectric ceramics. The fast tool servo driven by piezoelectric ceramics has many advantages such as fast response speed, high acceleration, wide frequency response range, and easy control.
The fast-tool servo micro-feed mechanism is a very important component in the fast-tool servo processing system. As a high-speed and high-precision displacement output mechanism, its performance has a direct impact on the surface quality of the micro-structure processed by the fast-tool servo processing. The P92 and P93 series piezoelectric fast tool positioners designed and developed by CoreMorrow have the advantages of large bearing capacity, fast response speed, wide frequency range, and nanometer precision. They are the first choice for fast tool servos
