Through Coolant Type (MQS) Spindles Revolving Through Coolant Coolant Type Machine Type Coolant pressure is approx. 0.5MPa 7MPa Stepped Holes Divide the two processes. Drill the larger hole first. Atool for machining both chamfer and spot face can be produced to order. Drill Length A DC x 1.5 Coolant Handling MMS Type (1)Small particles of swarf will jam in the oil hole. Use a filter as a preventative measure. When using small diameter drills use a fine mesh filter. (2)Dirt and dust particles in old coolant can clog the oil hole and prevent effective 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. interrupted Cutting 1 One Process O Lower the feed when drilling the interrupted part. Requires Prior Machining A Spot face with an end mill prior to drilling. N076
