The utility model discloses a
grinding wheel dressing device which comprises a
machine frame, an X-axis stand column sliding table and a Y-axis sliding table, the X-axis stand column sliding table and the Y-axis sliding table are arranged on the upper side of the
machine frame, a Z-axis sliding table is arranged on the upper side of the X-axis stand column sliding table, a C-axis sliding table is arranged at the
tail end of the lower side of the Z-axis sliding table, a spindle motor is arranged on the lower side of the C-axis sliding table, and a spindle is arranged on the spindle motor. Through the design of the collecting
barrel, chippings generated by abrasion of the abutting position of the
diamond pen and the
grinding wheel body can be effectively collected in the
grinding wheel body finishing process. In this way, later cleaning work is facilitated, the cleanliness of the
working environment is kept, potential hazards of chippings to equipment and operators are reduced, and after the
grinding wheel body is trimmed, the collecting
barrel is reset and abuts against the abutting
barrel through a spring in the inner cavity, so that the collecting barrel is reset. And the mechanism plays a role in protecting the
diamond pen when the
diamond pen is not used, so that the damage of the diamond pen caused by accidental collision or environmental factors is reduced, and the service life of the diamond pen is prolonged.
