What is cutting oil?
Cutting oil is a lubricant used during machining operations such as grinding, drilling, and turning. The oil is applied to the cutting tool to cool and lubricate the tool and workpiece, reducing friction and heat buildup. Cutting oils also prevent chips from welding to the tool and workpiece, making chips easier to remove. Cutting oils typically contain sulfur, chlorine, and other chemicals that can be harmful to the environment and human health.
How often should I reapply cutting oil?
While there is no one answer to this question as it will depend on the specific cutting oil being used as well as the application, in general, it is typically recommended to reapply cutting oil every few hours. This will help to ensure that the cutting oil is effective and can help to prolong the life of your tools.
