 — Aerostatic spindles are commonly employed in ultra-precision machines. The aerostatic spindle, as a critical key component for the development of industrial ultra-precision grinding machines, requires an industrial feasible precision engineering approach to robust design and optimization in order to render the high-precision spindle system.

 — Spindles can be designed optimally for either HSC or HPC. If a spindle needs to be used in both areas, a compromise between stiffness and load capacity on the one hand and achievable speeds on the other hand must be made. Structure. Spindles are made up of a large number of individual components. A typical design of a main spindle …

 — If the dulled grains stay in the wheel, they keep on rubbing on work without actually cutting. This defect is known as 'glazing.' If, on the other hand, the abrasive grains break away from the wheel or split prematurely, before becoming dull, it causes a reduction in life of the grinding wheel. Selection of Abrasives in Grinding

 — Vertical spindle/rotary table. This grinding machine is capable of heavy cuts and high metal-removal rates. Vertical spindle machines use cup, cylinder, or segmented wheels.
