[Prior art] Referring to FIG. 1, a general tool grinding machine 1 mainly includes a machine table u, a grinding wheel 12 provided at a fixed position of the machine table 11, a knife holder 13 capable of clamping a tool, and a knife holder 13 The transmission device 14, a link unit 15 capable of driving the transmission device 14, and a mold block 16 fixed on the machine table 11. The transmission device 14 has a base 41 fixed on the machine table 、, an axis-moving seat slidingly engaged with the base 141 and capable of sliding along an X-axis direction, and a shaft-moving base 142 sliding and being capable of sliding along a A radial displacement base 143 that slides in the γ-axis direction, and the radial displacement base 143 is used for fixing the cutter base 13. The connecting rod unit 15 has a first connecting rod 151 and a second connecting rod 152 which are juxtaposed to each other and are pivotally connected to the machine table 11 and the radial displacement seat M3, respectively. A first connecting rod 151 and 152 are pivotally connected to the first and second connecting rods 151 and 152.
