Efficiency improvement in the machining of titanium alloy bolts Cutting edge condition in special steel drilling application Cutting edge wear condition after drilling 900 holes

CUTTING CONDITIONS Drilling | Solid | Cutting conditions This cutting condition chart is based on the usage of water-soluble coolant and internal oil supply. Please use quality water-soluble coolant with a dilution factor of approximately 20 times. Please use a precision filter (approximation of 3pm to 5pm) to prevent the oil holes from clogging. 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 oil used. For accurate mounting, acceptable deflection of the body...

ADO-MICRO 12D/15D/20D/25D/30D Recommended drilling method for deep-holes ①ADO-MICRO 2D Make a pilot hole with the ADO-MICRO 2D. ②Insert the long drill into a pilot hole with a low revolution of 500 to 1,000 min-1 (n). ADO-MICRO 2D (140°) The ADO-MICRO 2D (140° point angle) is the recommended pilot hole drills of the ADO-MICRO 12D/20D/30D. ③ Increase the revolution to the designated speed and start drilling. ★ When work ing on a cur ved sur f ace, use the FX-ZDS (end mill for counterboring) or the ADF (carbide flat drill) to counterbore a flat surface before drilling a pilot hole. ④ After...
