Abstract

PURPOSE:To simplify constitution of a grindstone and perform grinding of a drill with a different point angle, by providing a chuck, holding the drill, in a rotary table and arranging the rotary table in a diagonally movable state for the grindstone. CONSTITUTION:The rotary shaft of a grindstone G is bearing supported to a quill 16 rotated by a motor ML. The quill 16 is vertically movably supportd to a spindle housing 17 horizontally sliding on a slide part 18. A rotary table 2 is provided by three rollers 35 to a diagonally moving plate 31, diagonally movably and fixably provided to a main unit 1, and rotated by a motor M2. A chuck 3a, holding a drill D, is provided in the rotary table 2. A turning axis of the diagonally moving plate 31 passes through the contact point of the point end of the drill D to the grindstone. Holding the drill D, if the rotary table 2 is rotated, the grindstone G is vertically and horizontally moved by cams 45, 46, provided in the periphery of the rotary table, through a link mechanism, in this way, adjustment of a grinding condition in accordance with change of a point angle can be easily performed.
