Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
Chattering and deflection have always been the bane of machinists’ existence, so much so that the sight of a long and slender tool holder will immediately cause goosebumps. If you understand why a long tool holder behaves the way it does, you’ll know that there are ways to fight back against this bending.
Maintenance is really important and kind of a pain. When it comes to all-important spindle maintenance, you can avoid the pain by using simple tools and devices.
If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original you risk unsatisfactory performance.
Hydraulic Chucks are ideal tool holders for machining processes that require high accuracy such as drills, reamers, ball mills, end mills, diamond reamers and grinding tools.
