Non-uniform rational B-spline (NURBS) curves are combined with the Kriging model to present a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking the removed area of the rail profile cross-section by grinding as the calculation index of ...

Grinding wheels come in many different sizes, shapes, and abrasives (Figure 5-7). Some of the various types are listed below. Straight Straight wheels, numbers 1, 5, and 7, are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and …
However, the grinding mechanism with such products has not been explained precisely yet. In order to understand it, we study the effect of two grinding aids on clinker grinding using a planetary mill.
Grinding for short periods was utilised to investigate the mechanism of formation for the hydrogen-bonded cocrystals of na and suberic acid (sub). The results suggest that the cocrystal formation occurs in a stepwise manner, wherein the cocrystal ( na )·( sub ) appears as an intermediate in the synthesis of the ( na ) 2 ·( sub ) cocrystal ...

Grinding behaviour and wear mechanism of self-fabricated rail grinding stones (GS) using zirconia alumina (ZA), white fused alumina (WA) and brown fused alumina (A) were investigated in detail. The results illustrated that the grinding efficiency grew ...
In this paper, surface/subsurface damage mechanism of engineering ceramics under ultrasonic vibration assisted grinding was studied by experiment based on its theoretical study. The study shows: under the same grinding conditions, ultrasonic grinding can realize plastic grinding and low crack damage surface grinding in a larger range of cutting depth than that under common grinding, that can ...
This is a small grinder operated with electric power. It can be easily carried anywhere. Grinding can be done by holding it in hand. It is used for cleaning the heavy welding jobs.. On one end of the motor shaft, a grinding wheel is fitted and on the …
