Research into cycloidal gearing gave Olly Dmitriev, CEO of Vert Rotors UK, the idea that the principles of this technology could be applied to a compressor. The new type of oil-free screw compressor developed and patented by Vert Rotors has proved to be 35 % more energy efficient than dry oil-free machines. The main reason for this energy saving is that there is no stator in the design, which is common in rotary twin shaft compressors and which allows the gas being compressed to leak back.
After SAUER had set the benchmark for the machining of CVD and PCD tool blades with its LASERTEC 20 PrecisionTool, the product portfolio in the ULTRASONIC range has now been extended by the addition of the ULTRASONIC 20 linear. This machine is capable of machining carbide metal tool bodies economically.
