Advanced and reasonable structure
(1)The machine has a reasonable layout and good overall rigidity. According to our experience, owing to the cantilever type of upper and lower arm, it constitutes tuning fork type structure with vertical columns so that the strong or weak of the columns rigidity directly affect the stability of the wire frame and roughness and accuracy of workpiece. That is why the columns sections are designed bigger to ensure the whole rigidity.
(2)All the bearings used in the ball screw of worktable parts are specially pairing produced by professional manufacturers (Harbin bearing factory), The pairing bearing can ensure the axial gap of bearings is within 0.004mm.
(3)Upper arm is equipped with taper head, not only it can cut taper workpiece, but also it is more convenient to adjust the molybdenum wire perpendicular degree.
(4)It has a high degree of automation. The processing process is full automatic, and also has the functions of wire broken automatic protection, brown-out protection and automatic center finding.
