ASA - Automated Solutions Australia is a leading robotic automation integrator supplying customized five-axis high-speed machining centers to automotive, aerospace and precision mold industries worldwide.
Conventional general P4 bearings could not sustain 28,000 r/min long-cycle cutting—rapid heat accumulation, gradual precision attenuation and spindle chatter failed high-gloss machining and damaged overseas reputation.
Supply custom P4S reinforced ultra-precision spindle bearings with low heat generation, stable long-term accuracy and strong rigidity to replace imported bearings, sustaining 28,000 r/min operation and lifting export machine-tool competitiveness.
28,000 r/min cyclic cutting made ordinary P4 bearings generate massive friction heat, triggering precision decay and vibration.
Aerospace and mold workpieces demand ultra-low spindle runout; bearing-error vibration caused poor gloss and high scrap rate.
Bearings had to balance ultra-high speed, high axial rigidity and sustained heat resistance at once—standard bearings could not.
Centrifugal force threw grease out during long high-speed runs, causing dry friction and accelerated wear.
Super-finished raceways minimize waviness and ball deviation, drastically cutting high-speed friction heat.
Full micron-level control of ring dimensions, face runout and radial clearance ensures repetitive positioning accuracy.
Low-viscosity grease resists centrifugal throw-out for stable long-term heat dissipation and continuous lubrication.
Boosted axial rigidity suppresses spindle chatter during heavy alternating five-axis cutting.
Spindles fitted with 60BNR10S P4S bearings sustain steady 28,000 r/min cutting with temperature rise below 28℃; workpiece surface finish improved one grade, precision-attenuation failures dropped 92%, and ASA's overseas five-axis export orders grew significantly.
