An air film between bearings and a high performance motor, high-precision and ultra high speed machining are possible. Also, as the spindle life is long and cleanliness of supply air is very high, this spindle is widely used as the main spindle, wheel spindle and indexing spindle in a broader range from high-precision machining to ultra high speed machining.
Aerostatic table spindle:
This spindle is widely used for the turn table and indexing table of high-precision machine tools. It can also serve effectively as the attachment for machining and measuring high-precision parts. The spindle life is long.
Performance of the V-V slide guideway is assured by our outstanding workmanship. It is very ideal in terms of accuracy, rigtdity, movement and stability, and is essential for the guide of high-precision machine tool, equipment and measuring instruments.
This guideway eliminates friction which is present in sliding guideways, by featuring very precise needle bearings, thus accurate positioning can be realized. Fine undulation is as small as 20 nm or less, which assures remarkable accuracy equivalent to a hydrostatic bearing. The table floats less at high speed travel. This technology is essential for the guide of a linear coater requiring high speed motion and high accuracy positioning. The V-V guideway has a structure preloaded by gravity. A vertical V-V roller guideway is also available applying preload with aerostatic pressure.
