CARBIDE ISB/MB/LB/XB TYPE DRILL OPERATIONAL GUIDANCE Drill Holding Thrust bearing type collet chuck holds the drill securely. Coolant pressure is approx. 0.5-1 MPa (2-3MPa for DC<5, 1,5MPa at minimum for DC<3 Recommended coolant pressure:>3Mpa). Coolant volume is 1.5 4.0l/min. (For DC>3) Interrupted Cutting(DC>3) v i X J One Process OK Lower the feed when drilling the interrupted part. Requires Prior Machining Spot face with an end mill prior to drilling. Drill Length VPl A 1 , DC A>D< (DCxover 2 :xi.5 0 for DC<3) Drill Installation When machining a prepared hole with the MWS-SB please set the depth to 1 DC (DC=drill diameter). For pilot hole drilling when DC Is up to 3, use the SB type drill. Use the prepared hole as a guide when using a drill with an oil hole. Depending on the cutting conditions, peck feed Is recommended. Stepped Holes(DC>3) Divide the two processes. Drill the larger hole first, A tool for machining both chamfer and spot face can be produced to order. Drill Installation NG Do not clamp on the flutes. Installation Tolerance(DC>3) Run-out 0.03mm Coolant Handling 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. Burring and Workpiece Chipping(DC>3) r 1 Lower the at the end cutting. Add a 45°c Change the eed rate by 50% Df through hamfer. point angle. NOTES ON USE (For DC<3) Please use a fine mesh filter (mesh<3Atm) 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.) Through Coolant Type(DC>3) Spindles Through Coolant Type 4 Revolving Coolant Machine Type TECHNICAL DATA > R001 P119 DRILLING
