Sandvik’s Golden Rule

For several years Sandvik has been publishing a series of “Tips Films” designed to provide hands-on application knowledge. This collection of videos, most of which are two minutes or less, gives users a treasure trove of information. All you need to do is scan the list of topics and pick what interests you.

The Golden Rule

As an example, there’s a video called “The Golden Rule” that shows the advantages of thick to thin milling. They show why generating thick chips on exit leads to edge failure and poor tool life. The cutter position forms the chip, and it’s much better to create a thick chip as you enter, and a thin chip as you exit, resulting in less stress on the insert. Sandvik encourages us to remember the Golden Rule: “Think to Thin.” This process should ensure the smallest chip thickness possible when exiting a cut. Proper cutting action and chip formation saves time, money, and ensures a stable process.
