CARBIDE I OPERATIONAL GUIDANCE Drill Holding Thrust bearing type collet chuck holds the drill securely. Thin Workpiece hi id OK Support the Workpiece NG If Bending Occurs Coolant Method (MVE) 1 J Is Two coolant positions, at the end and at the center are ideal. Drill Length A > DC x 1.5(DC over 2.0 for DC<3) Interrupted Cutting Va I/P One Process OK Lower the feed when drilling the interrupted part. J 3 Requires Prior Machining Spot face with an end mill prior to drilling. Through Coolant Type (MVS) Spindles Revolving Through Coolant Coolant Type Machine Type Less than 03mm : 1,5MPa-7MP More than 03mm : 0.5MPa-7MPa More than 3MPa is recommended. Drill Installation NG Do not clamp on the flutes. Stepped Holes Divide the two processes. Drill the larger hole first. A tool for machining both chamfer and spot face can be produced to order. Coolant Handling MVS Type> 1) Small particles of swarf will jam in the oil hole of small diameter drills. Always use a fine mesh filter as a preventative measure. 2) Dirt and dust particles adhere to the oil in old coolant and prevent an efficient flow. Regular coolant exchange is recommended. NOTES ON USE (For DC<3mm) Please use a fine mesh filter (mesh<3jum) for coolant to prevent jamming in the oil hole. For deep drilling with the long type drill, machining a pilot hole is recommended. (Otherwise, centrifugal forces may cause drill breakage.) Installation Tolerance Run-out 0.03mm Burring and Workpiece Chipping Lower the feed rate by 50% at the end of through cutting. 0Add a 45°chamfer. Change the point angle. Drill Installation Make approx. DCx1 (DC=drill diameter) pilot hole by using the MVS with the shortest flutes. Use the pilot hole as a guide and machine by the drill with coolant hole. Depending on the application, carry out pecking. TECHNICAL DATA > R001 P049 DRILLING
