Рекомендации являются только начальными параметрами и могут изменяться в зависимости от условий резания, таких как жесткость шпинделя и приспособления. Для надлежащей работы сверла требуется минимум 250 psi охлаждающей жидкости через инструмент. Если это невозможно, параметры резания может потребоваться снизить.
Начните с середины диапазона и отрегулируйте параметры резания в соответствии с вашими условиями резания. Для сверл с соотношением длины к диаметру 4:1 может потребоваться уменьшить подачу на 40% для первых 0,06 дюйма глубины сверления. Затем увеличьте до полной подачи для остальной части резания.
