For high productivity processing, a higher feed rate is required to make the spindle speed at the beginning of the modern CNC era twenty years ago when it is considered impossible.
Faster rotation of the cutting tool is productive, and as the physics of the rotating body becomes dominant, the new problems of the tool will also pay attention. It is not enough to tighten a chuck with only one box wrench.
Today, if the operation requires the use of today‘s machines and cutting tools to provide maximum performance, then the balance, shape factor and a variety of vibration modes must be considered some factors.
Key tool properties remain well.
Does the cutting tool affect retention? More than many mechanics and engineers realized. The amount of handle available for gripping is an important factor. BIG KAISER recommends the following length
It is important not to forget other factors.
Polished handle to reduce friction, as well as the knife handle and turret cleanliness. Oil and coolant reduce clamping force. The cutting tool roundness is usually considered close enough to be perfectly ignored, but in fact high speed performance requires 25 parts per million tolerance.
Similarly, the tool handle diameter of the ISO h6 tolerance is important, for smaller tools, this can mean 0-6 micron repeatability. Most shops lack the ability to check the tolerance of low micron diameters, so a good tool supplier is essential.
