Consider the life of wheel bearings on a conventional car driven at conventional speeds. Next, consider the life of wheel bearings in a race car that goes 200 miles per hour. When the spindle is rotating the tool at a high speed, runout and unbalance conditions can lead to excessive wear on one side of the tool, which can result in a variety of problems. Tool balancing is a must. Otherwise, there could be a dangerous projectile flying through the plant.
Small variations tend to be greatly amplified when the speeds and feeds are turned up.
So careful consideration of all aspects is essential. Which leads us to a fundamental question of whether the capabilities of machine tools have outstripped the performance capabilities of the cutting tools. Perhaps not surprisingly, Pitsker doesn't think that's the case. He argues that given the right planning, it is a draw between what the machines can do and how the tools can perform.
