High Speed Spindle Design and Construction : .

This allows the spindle to rotate at higher speeds as a complete unit, without the additional limitations of belts or gears. In general, a complete motor-spindle is comprised of the spindle shaft, including motor element, and tooling system. The spindle shaft is held in position by a set of high precision bearings. The bearings require a lubrication method, such as grease or oil. The spindle ...

Super-High Speed Point Grinding | Scientific.Net

Abstract: The technology of super-high speed point (SHSP) grinding will bring in higher precision and productivity for component manufacturing. The surface roughness attained by SHSP grinding is analyzed in this paper based on the contact area and the probability distribution of chip thickness while the swivel angle of α exists, proposing a new method to predicate the value of the roughness ...

Analytical prediction for depth of subsurface .

Therefore, lower SSD depth can be achieved with lower feed rate, lower wafer rotation speed, and higher grinding wheel speed. 5. Conclusions (1) A theoretical model that can predict the SSD depth in silicon wafer during self-rotating grinding is proposed, and SSD depth is analytically expressed as a formula of the grinding parameters, the size of the abrasive grains and the radial distance ...

High speed CNC grinding - FANUC

During grinding, the effect of wear on the grinding wheel has an impact on the accuracy of the finished workpiece. This effect is exaggerated on longer grinding processes. To counter this and ensure consistent accuracy, your CNC needs to be able to compensate for wear by adjusting the position and speed of the grinding wheel.
