To achieve a good knurl, what should you apply to the workpiece?

  1. Heat

  2. Water

  3. Coolant

  4. Grease

The correct answer is: Coolant

To achieve a good knurl on a workpiece, applying coolant is crucial. Coolant serves multiple purposes during the knurling process. It helps reduce friction between the knurling tool and the workpiece, which is essential for ensuring a clean and precise pattern. Additionally, coolant helps dissipate heat generated during the machining process, which can degrade both the tool and the surface finish of the workpiece. Moreover, using coolant allows for better chip removal from the knurling area, preventing chip buildup that could lead to a poor quality knurl. The application of coolant contributes to prolonged tool life and enhances the overall effectiveness of the knurling operation, ensuring that the desired texture and grip are achieved without compromising the integrity of the material.
