• The SIEMENS 828D numerical control system is adopted to realize the motion control of the longitudinal motion of the worktable (Z axis), the transverse motion of the grinding wheel frame (X axis), the rotation of the workpiece spindle (C axis) and the rotation of the grinding wheel frame (A axis), and also control the two analog spindles of the grinding wheel spindle motor and the diamond roller correction motor;
• The machine has the special functions of automatic grinding cycle, automatic online dressing of grinding wheel and automatic compensation of dressing amount;
• The grinding wheel dresser can be installed with diamond disc wheel, and the grinding wheel can be trimmed into various required cross-sectional shapes through the linkage of X-axis and Z-axis. Diamond rollers can also be installed to carry out high-efficiency molding correction on the grinding wheel to meet the needs of mass machining parts;
• X-axis, Z-axis configuration grating, C- axis configuration circular grating, to achieve full closed-loop control;
• The adjustment of the grinding wheel frame angle is automatically controlled by the servo motor, and the spiral angle value of the thread of the processed part can be displayed on the operation interface, which is convenient for the operation of the machine tool.
