CARBIDE SB MB LB XB Type Dril Drill Holding Thrust bearing type collet chuck holds the drill securely. Through Coolant Type(DC3) Coolant pressure is approx. 0.5-1 MPa (2-3MPa for DC5 1.5MPa at minimum for DC3 Recommended coolant pressure:3Mpa). Coolant volume is 1.5 4.0l min. (For DC 3) Interrupted Cutting(DC3) One Process O Lower the feed when drilling the interrupted part. Requires Prior Machining A Spot face with an end mill prior to drilling. OPERATIONAL GUIDANC Drill Length A DC x 15(DC over 2.0 for DC3) Drill Installation When machining a prepared hole with the MWE-SB please set the depth to 1 DC (DCdrill diameter). For pilot hole drilling when DC is up to 3 use the SB type drill. (2)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(DC3) Divide the two processes. Drill the larger hole first. Atool for machining both chamfer and spot lice can be produced to order. Drill Installation Do not clamp on the flutes. 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. installation Tolerance(DC3) Run-out 0.03mm Burring and Workpiece Chipping(DC3) Lower the feed rate by 50% at the end of through cutting. Add a 45chamfer. Change the point angle. NOTES ON USE (For DC3) Please use a fine mesh filter (mesh3 im) 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.) TECHNICAL DATA -Q001 N051 DRILLING
