MB-type medium-feed wire EDM machine

◆ The machine tool is equipped with a reactive stepper motor. ◆ The T-shaped bed is manufactured using resin-bonded sand casting and undergoes two high-temperature heat treatments, effectively controlling machine tool deformation. ◆ It employs precision linear guides from Taiwan and precision ball screws with double nuts from Taiwan, ensuring long-term maintenance of machining accuracy. Low-voltage, non-blocking, constant-current high-frequency power supplies are used for cutting operations, resulting in leading domestic performance in key process metrics such as cutting efficiency, surface roughness, and molybdenum wire wear. ◆ A constant-voltage power supply with narrow pulse width and high current is used for tool dressing, significantly enhancing the stability, consistency, and overall process performance of multi-pass cutting. ◆ Rational, environmentally friendly, enclosed structural design.

MB-type medium-feed wire EDM machine

◆ The machine tool is equipped with a reactive stepper motor.
◆ The T-shaped bed is manufactured using resin-bonded sand casting and undergoes two high-temperature heat treatments, effectively controlling machine tool deformation.
◆ Employs precision linear guides from Taiwan and high-precision ball screws with double nuts, ensuring long-term maintenance of machining accuracy. Utilizes low-voltage, impedance-free, constant-current high-frequency power supplies for cutting operations, resulting in process performance metrics—such as cutting efficiency, surface roughness, and molybdenum wire wear—that are among the best in China.
◆ A constant-voltage power supply with a narrow pulse width and high current is used for tool dressing, significantly enhancing the stability, consistency, and process performance of multi-pass cutting.
◆ Rational, environmentally friendly enclosed structural design.
