How to achieve extended tool life and an improved finish
Simon concluded: “Tools with highly polished surfaces means better cutting edges which will ensure extended tool life and improve the finish on the machined part. We have seen the demand for tools with a superior surface finish continue to increase and cutting tool manufacturers are producing more highly polished tools in larger quantities.”
Tips on achieving a superior tooling surface finish
- The quality of the grinding wheel is critical in achieving a high-quality surface finish. A fine-grit wheel can form small chips during grinding which could impart fine marks on the flute face and gash.
- Using a fine-grit also poses a challenge as the wheel must be fine enough to produce the required surface finish while maintaining a good toroid radius over a batch of tools.
- Ensure the wheel is properly trued and dressed so that it performs as expected.
- Ensure efficient coolant delivery and fine filtration systems are in place.
- Ensure the grinding wheels are balanced correctly using iBalance
