DRILLING DRILLING(SOLID carbide) MHS WSTAR DRILLS OPERATIONAL GUIDANCE Drill Holding Thrust bearing type collet chuck holds the drill securely. Drill Installation 1) Make approx. DCx1 (DC=drill diameter) pilot hole by using the MHS with the shortest flutes. 2) Use the pilot hole as a guide and machine by the drill with coolant hole. Depending on the application, carry out pecking. Stepped Holes Divide the two processes, Drill the larger hole first, A tool for machining both chamfer and spot face can be produced to order, Drill Length A> DC x 2 Drill Installation NG Do not clamp on the flutes. Coolant Method Spindles Through Coolant Type Revolving Coolant Machine Type Less than 03mm: 1,5MPa-7MP More than 03mm : 0.5MPa-7MPa More than 3MPa is recommended. 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.
