The HPS series spindles NSK America Corp. (Schaumburg, IL) are fully automatic tool changeable from the machine magazine to the main machine spindle. Available with either 25,000 rpm or 50,000 rpm and accurate within 1µm (T.I.R.), these pneumatically driven spindles are perfect for applications where small diameter hole drilling or light finish milling are required. The HPS series eliminates the need to rotate the machine’s main spindle, saving main spindle wear. The gearless operation eliminates heat and vibration affording high rpm for micro milling and drilling of all material. Available with either BT30 or CAT 40 arbors, the HPS series can convert a standard slow rpm machine into a high speed machining center.
