Technical parameters for die polishing machine Processing range (mm): 0.35-5.00 Power: 220V 50HZ Maximum output power (W): 150 Transducer: Japanese nickel-chip inductive Frequency (KHZ): 25 Die-seat speed (rpm / min): 180 Die-seat swing (time / min): 150 Swing angle: not less than 12 degrees (adjustable)   C.working principle and equipment constitutes This machine uses ultrasonic high-speed vibration, and via the steel needle and abrasive to strike on the processed surface, grind processed surface to meet the needed shape and size. This equipment consists of ultrasonic generator, transducer and machine base. (1) ultrasonic generator: ultrasonic generator is installed in a 450mm * 210mm * 410 mm iron box. Line uses automatic frequency tracking, correct automatically frequency of different steel needle to match each other, so as to achieve ultrasound output and shock effect. (2) transducer: It is pure nickel film of water-cooling type with efficient transducer effect.The ultrasound can be converted into smooth ultrasound shock, using water cycle cooling, and has the characteristic of low noise. We can make wire drawing machine,layer winding machine,drum packing machine,die polishing machine,pay off machine and take up machine,butt welding machine and pointing machine.
