Ultrasonic trimming is the special cutting method to cut materials by the cutter equipped at the toe of the ultrasonic oscillator with 35,000 times/sec.

Combined ultrasonic cutter unit is equipped with robots to cut work in 3-D way.

While Ultrasonic cutter is already applied in various field, we hereby introduce the method mainly applied for automotive interior material. Namely, it is applied for relatively soft and thick material which has complicated 3-D surface and contains glass fiber.

The cutter blade is made of high speed tool steel and carbide.

The oscillator is specified for high speed & heavy load cutting. The oscillator consists of PZT and auto tracing control is employed to secure stable cutting.

The cutting tool is held with 6 axes or 7 axes vertically articulated robot so that most suitable motion is available for this method.

Following technologies constitute this method; Material fixing, pressure cutting, profiling cutting, cutting condition optimization (feeding rate, feeding direction, blade position and oscillating direction etc.), blade monitoring, auto grinding, off-line teaching and robot engineering etc.
