For ferrous materials like steel and stainless steel, a heavy-duty oil with extreme pressure (EP) additives is necessary to handle the high stress. Choosing the right formulation ensures optimal performance and protects both the tool and the integrity of the workpiece.
Maintaining Cutting Oil Microstructure Integrity During Metal Drilling
When a drill bit rotates and applies pressure, the kinetic energy is converted into thermal energy through friction. Selecting the Right Formulation Not all cutting oils are created equal, and selecting the correct one depends on the base metal being drilled.
The application of a cutting oil serves as a critical intervention, creating a protective barrier that separates the drill from the workpiece. By drawing heat away from the cutting edge, the oil keeps the metal within its optimal working temperature range.
Preserving Cutting Oil Microstructure Integrity During Metal Drilling
This softening process, known as thermal annealing, causes the edge to roll and deform rather than cut, resulting in oversized holes and a frustrating cycle of constant sharpening. If this heat is not dissipated, the metal at the cutting edge reaches a critical temperature where the steel loses its temper.
