General Drilling Operations
β
Note: 1. The table above assumes a milled-flat surface and water soluble coolant. 2. Use a rigid and precise machine and holder. 3. Please minimize overhang length as much as possible during machining. 4. Adjust the rotational speed and feed in accordance with conditions such as the machining shape, machine rigidity, or work holding. 5. Please set up the drill so that the runout of the cutting edge is under 0.0008”. 6. Please select a cutting fluid that is most suitable for the work material with minimal smoke formation. 7. In the case of dry machining, please use air blow to remove chips to prevent clogging. • Please do not machine stainless steel dry. 8. When machining an inclined plane, adjust the rotational speed and feed in accordance with the angle of the incline (β). • When the machining incline angle (β) is less than 30°, please reduce the feed to 40-60%. • When the machining incline angle (β) is over 30°, please reduce the speed to 60-80% , the feed to 20-40%. 9. Please use step drilling when drilling in pre-drilled holes to improve chip separation. 10. If it is necessary to ensure the locating precision of the hole to be machined, adjust the rotational speed and feed as indicated above (in accordance with the machining precision requirement) . 11. 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.
