NSK's AMS Series Air Turbine Spindles Produce Smooth Surfaces, Even in Heavy Milling Applications



Schaumburg, IL- (July 29, 2003) Studies have determined that NSK America's AMS Air Turbine Spindles with a built-in air bearing effectively machine and produce superior surface finishes during heavy milling.

Through research, NSK has proven heavy milling applications with excellent surface roughness results is possible when using the AMS-1600 and a 3 mm diameter coated end mill. Tests performed on an aluminum block (A5052) generated surface roughness as low as 0.57 5m. These findings were based on a cutting depth of 0.05 x 2.5 mm and a feed rate of 2,500 mm/min.

The AMS high-speed air turbine type spindle utilizes an air bearing which contributes to a longer service life due to lack of friction, wear and heat generation. The spindle and the bearing are finished with an extremely high-accuracy precision process, virtually eliminating vibration and providing extremely high rotating accuracy. Therefore, the AMS spindles are ideal for operations requiring extreme precision.

NSK offers the AMS-400, the AMS-800 and the AMS-1600 with speeds of 57,000, rpm 80,000 rpm and 160,000 rpm respectively.
