Using the latest manufacturing technology, stripping is more stable, winding wire break, movement phenomenon obviously decreased.To optimize the design of the mechanical structure, improve the overall mechanical performance, repeated positioning error further cuts.Using high resolution servo motor, torsion Angle more accurately.Main shaft adopts the Germany technology development and production, further reduce jitter error, satisfies the requirement of various tubular high inner diameter of the coil.Products are widely used in high frequency, new energy, such as the network transformer industry.
