Coolant Adjustment

Coolant Recommendation Example | Imperial If the recommended coolant pressure and flow is 600 PSI and 12 GPM for a 3xD tool, the adjusted pressure and flow for a 9xD tool would be: 600 x 1.2 = 720 PSI 12 x 1.2 = 14.4 GPM Coolant Recommendation Example | Metric If the recommended coolant pressure and flow is 42 bar and 32 LPM for a 3xD tool, the adjusted pressure and flow for a 9xD tool would be: 42 x 1.2 = 50.4 bar 32 x 1.2 = 38.4 LPM

Refer to Speed and Feed charts for recommended adjustments to speeds and feeds. Refer to page 196 for deep hole drilling guidelines.

Factory technical assistance is available for your specific applicaƟons through our ApplicaƟon Engineering Team. ext: 7611 | email: appeng@alliedmachine.com WARNING

NOTES: • Coolant must have proper addiƟves to prevent excessive foaming during drilling cycle. • PosiƟve displacement coolant pump is recommended to maintain coolant flow at recommended values. • The coolant filter must be less than 5 microns. Fine filtraƟon is necessary to prevent blockage of the smaller coolant holes of the solid carbide tool.
