MagicDrill DRA Flanged shank SF Cautions for installation on machining center For installation of Magic Drill DRA 1st choice 2nd choice Hydro chuck, power chuck, collet chuck, etc. Side lock arbor Hydro chuck Power chuck Install Magic Drill DRA to the chucks Collet chuck Example of side lock arbor Cautions for machining with 8D/12D holder Precautions for KM chipbreaker Recommended machining Machining on casting surface 1 Make a center spot using DRA 1.5D/3D/5D type. Decrease feed to 0.15 mm/rev until full drill diameter has entered the workpiece (Center spot should be at least half of cutting diameter) 2 Then drill the hole using DRA (8D/12D type). Decrease feed rate as chisel point 1 DRA 2 DRA 8D/12D enters the workpiece until full diameter is achieved K Spot drilling Applicable workpieces Not recommended workpieces Applications Shape ofworkpiece Caution for machining Applications Shape of workpiece Applications Shape of workpiece 1. When machining stainless steel, for hole depths of up to Plain 0.5DC, keep feed rate at 0.15mm/rev or less. *Hole expansion *Slant surface surface 2. Internal coolant is recommended for smooth chip removal. For stainless steel, the combination of internal and external coolant is recommended. 1. Fix stacked plates securely to ensure they do not slip Stacked while machining. Applications Shape of workpiece Applications Shape of workpiece plates Half cylindrical *Cored hole 1. When machining concave holes, set the feed rate at half of Concave recommended feed or less for continuous hole machining. surface 2. Utilize a step feeding if chips are not broken short at the inlet. * Machining possible with FTP and 1.5D toolholder 1. Hole machining above the centerline Pipe material of the pipe is possible. 2. Do not machine on curved surface areas. Center portion *Curved surface machining portion machining * Machining possible with FTP and 1.5D toolholder K28 Drilling
