MagicDrill DRC  Applicable workpiece  Not Recommended workpieces Applications Shape of Workpiece Caution for machining Applications Shape of Workpiece 1. Due to good chip control, step machining is not necessary for Low Carbon Steel. Slant Plain 2. When machining SUS304, for hole depths of more than 2.5D, Surface Surface utilize the step machining process. 3. In order to have smooth chip removal, we recommend internal coolant. 1. Fix stacked plates securely to ensure they do not slip while Half Stacked machining. Cylindrical Plates Original hole Next hole Hole 1. If the overlap amount is less than Expansion 1/3 x D, machining is possible. Cored Hole ID Less than 1/3×D Concave 1. When machining concave holes set the feed rates at half or Surface less than continuous hole machining. Pipe 1. Hole machining above the centerline of Material the pipe is possible. 2. Do not machine on curved surface areas.
