C3 ft OPERATIONAL GUIDANCE Drill Length A DC x 1.5 Interrupted Cutting v J One Process O Lower the feed when drilling the interrupted part. Requires Prior Machining A Spot face with an end mill prior to drilling. Through Coolant Type MVS) Spindles Through Coolant Type 4 Revolving Coolant Machine Type Coolant pressure is approx. 0.5-1 MPa ( 5:2 3MPa). Coolant volume is 1.5 4.0l min. Drill Installation Do not clamp on the flutes. Stepped Holes Divide the two processes. Drill the larger hole first. Atool 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. Installation Tolerance Run-out 0.03mm Burring and Workpiece Chipping Lower the feed rate by 50% at the end of through cutting. (2)Add a 45chamfer. Change the point angle.
