美国最近出售一种叫做“超声刀”的新型超声切割工具,可以切割各种坚硬的和易碎的材料,如多层玻璃纤维或石墨纤维制品等,不管干或湿的工件都可以进行切割。超声刀采用超声波换能器激励刀片,刀片以分子态切割,无残余灰尘或碎片。该切割工具不会产噪声或其它使人不舒服的感觉。 The United States recently sold a new type of ultrasonic cutting tool called the “Ultrasonic Knife” that can cut a variety of hard and brittle materials, such as multi-layer glass fiber or graphite fiber products, can be cut regardless of dry or wet workpieces. Ultrasonic blades use ultrasonic transducers to excite the blade, which is molecularly cut without residual dust or debris. The cutting tool does not produce noise or other uncomfortable feeling.
