The R-150DG is a four-axis CNC tool grinding machine, consisting of a grinding wheel swing axis (X-axis), grinding wheel tilt angle (B-axis), workpiece horizontal plane rotation axis (C-axis), and workpiece feed axis (Y-axis). The workpiece feed axis (Y-axis) is equipped with an encoder for closed-loop position feedback, ensuring micrometer-level grinding accuracy. This machine tool is suitable for the production of medium to large quantities of alloy inserts, PCD inserts, and CBN inserts. Once centered, a single switch press automatically completes the grinding under the force of a heavy hammer, achieving the ideal state of "constant pressure grinding and flexible feed." Due to the high hardness of diamond materials (PCD), the grinding wheel wears quickly, and the system can automatically detect and compensate for this wear, maintaining the size accuracy of the grinding process for extended periods.
