CARBIDE OPERATIONAL GUIDANCE Drill Holding Thrust bearing type collet chuck holds the drill securely. Coolant Method MZE) Two coolant positions at the end and at the center are Ideal. Thin Workpiece t hi id If Bending Occurs X Support the Workpiece O Drill Length DC x 1.5 Through Coolant Type (MZS) Spindles Through Coolant Type Revolving Coolant Machine Type 4 i Coolant pressure is approx. 0.5-1 MPa (05:2 3MPa). Coolant volume is 1.5- .OI min. interrupted Cutting s Y One Process O Lower the feed when drilling the interrupted part. Requires Prior Machining A Spot face with an end mill prior to drilling. Drill Installation Do not clamp on the flutes. Drill Installation When machining a prepared hole with the MZE-SA please set the depth to 1 DC (DCdrill diameter). 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 Divide the two processes. Drill the larger hole first. Atool for machining both chamfer and spot face can be produced to order. Installation Tolerance Run-out 0.03mm Coolant Handling MZS 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. Burring and Workpiece Chipping Lower the feed rate by 50% at the end of through cutting. Add a 45chamfer. Change the point angle. CAUTION TO USE MZS TYPE (Drill Diameter t3) Please use a fine mesh filter (mesh3jum) for coolant to prevent jamming in the oil hole. For deep drilling (l d3) machining guiding hole is recommended. (Use MZE..; :. SA type for guiding hole.) Pick drilling is also effective.
