A MICRO DRILL REGRINDING DEVICE

摘要

The present invention relates to a drill bit regrinding device and, more specifically, relates to a drill bit regrinding device having a micro-drill bit pressurized and fixated during regrinding, and having an efficiency of washing foreign materials enhanced before a quality inspection to raise the quality of regrinding the micro drill bit. Also, the drill bit regrinding device to regrind a micro drill bit comprises: a tray having a micro drill bit to be reground mounted thereon; a transfer part to transfer a tray; a rotating part to rotate horizontally at a predetermined angle while having the micro drill bit to be reground fixated thereto; a grinding part to regrind one among the drill bits to be reground, which has been fixated to the rotating part; and a clamping part to pressurize and fixate a side surface of a blade of the micro drill bit from an upside to prevent a defect caused by a trembling of the micro drill bit during regrinding via the grinding part.
