This cutting condition chart is based on the usage of water-soluble coolant and internal supply . 2. Please use quality water-soluble coolant with a dilution factor of approximately 20 times, e.g. 5% concentration. 3. Please use a precision filter (rating of 3 μ m to 5 μ m) to prevent the oil holes from clogging. 5. For accurate mounting, acceptable deflection of the body cylindrical part at the shank end should be less than 0.002μm , as shown in the illustrated figure. 6. For work materials with poor chip evacuation, please perform step drilling as required.
7. Please always use the appropriate cutting fluid recommended by the cutting fluid manufacturer in the machining of magnesium alloys. Be cautious with the cutting chips as they are highly flammable and may pose a serious fire risk if not properly handled.
4. Although the recommended coolant pressure is 3 MPa or more, please adjust accordingly if the level of flow volume is unsatisfactory due to the type and concentration of cutting fluid used.
