With the advent of ultrasonic vibration processing machines, Gitemai Group has brought a revolution in the field of brittle material processing, enabling efficient processing including ceramics, glass, cemented carbide, silicon, graphite, composite materials and precious stones. The concept is completely new.
Today, in the medical equipment, optical industry, automotive industry and other fields, the demand for high-hardness parts is increasing, and the popularity of "advanced materials" such as ceramics, glass and hard alloys meets the needs. However, on the one hand, these materials have extremely excellent properties (such as: light weight, corrosion resistance, high temperature resistance, abrasion resistance, etc.); on the other hand, due to the high hardness and brittleness of these materials, they are processed using conventional processing methods. Machining, such as grinding with a diamond wheel, is almost impossible or very expensive.
In the face of challenges, ultrasonic vibration processing technology has made a leap in processing in this field. This technology is based on the theory of vibration cutting with 30 years of experience and was developed by Sauer GmbH, Germany. Since Gitemai has a controlling stake in the company, Sauer GmbH became the tenth production plant of the Gitemai Group, the largest manufacturer of metal cutting machine tools in Europe.
"Ultrasonic vibration processing", as the name suggests, is the addition of ultrasonic vibration during the cutting process. Milling knives, drill bits or grinding wheels made of industrial diamond granules, which can strike up to 20,000 times/s on the surface of the part during processing, even the hardest material, in such high-frequency vibration tapping Underneath, a small cutting force can also disintegrate it. Of course, the feed force we use is still relatively large. In the past, when such a brittle material was processed, it usually took several different steps and consumed a lot of time. At the same time, the processing cost was greatly increased due to the wear of the tool. In contrast, the use of ultrasonic vibration processing makes the whole process simple and straightforward, and has many unprecedented advantages:
(1) Compared with the traditional method, the processing efficiency is increased by up to 5 times.
(2) Excellent surface quality, Ra
(4) Due to the low cutting force and temperature rise, the tool and workpiece can be optimally protected.
(5) Diamond tools without passivation have low cutting force and high material removal rate.
(6) Long machine life.
