During machining, high speed is often associated with heat generation. But with the Alberti air-driven turboflex spindles from Koma Precision Inc. it’s possible to reach 60,000 rpm without overheating the tool, according to the company. They are available as a straight or 90° tool.
These high-performance spindles can be easily installed on the machine through a special stop block and controller unit connected to the NC. ATC spindle designs can be integrated to automated tool change systems to provide faster tool changes and increased productivity. These are most suited for micromachining, engraving, small drilling, milling and polishing operations.

gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- numerical control ( NC)
numerical control ( NC)
Any controlled equipment that allows an operator to program its movement by entering a series of coded numbers and symbols. See CNC, computer numerical control; DNC, direct numerical control.
Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.
