Machine Tool Spindles

With the development of automated machining, the need for specialized secondary operations has resulted in the development of a wide variety of compact machining spindles capable of milling, drilling, slotting, engraving, and deburring. And as molds, dies and machined parts have been engineered smaller and more intricate, cutter diameters have likewise decreased, creating the need for increased spindle speeds to drive the cutting tools.

We have gathered together products from the leading manufacturers of compact machining spindles. Whether you are engraving details on a mold cavity, cutting electrodes for and EDM, drilling holes with a robotic arm, or turning intricate medical parts on a swiss screw machine, these spindles will offer many solutions for time-saving operations that will increase productivity and reduce cycle times.

Spindles fall into three main categories – belt driven, pneumatically (air) driven, and electrically driven. Belt-driven spindles are usually designed for specialty application machine building. Air-driven spindles are the most popular, as they generally, provide longer spindle life due to the air cooling and oil-mist lubrication. They are usually less than half the price of the electric spindles. Electric spindles, on the other hand, offer increased flexibility with a wider range of speeds, greater maximum power output, coupled with a flatter torque curve.
