A summary of railway track rectification and grinding wheel for track grinding;

JS1100 automatic controlled rotation test machine for grinding wheel;

Application of grinding wheel construction voucher of intelligence type;

Improvement and application of abrasive wheel adjuster;

The paper enumerates the section calculation formula of sprocket hob grinding abrasive wheel and its calculation process.

For influence of the interaction of vibration of wheel and workpiece on a ripple on the workpiece surface, this system adopts single-plane balance correction for the principal axises of wheel and workpiece synchronouslly,and it analyzes integrally the balance condition of whole system and the surface error of workpiece by processing the vibration data of wheel and worpiece together.

Analysed the influence of the abrasive wheel microvibration to the workpiece surface quality on ultra-precision grinding process, and established a mathematical model describing how vibration led to the error of workpiece surface profile.

As the material of grinding wheel dresser, the dressing Performance of PCD is near to that of a single crystal diamond, but itS price is relatively lower.

The clash between the emery wheel and the brown rice in rice milling machine,can get rid of most or all of bran.

The emery wheel and cutting piece manufactured by this adhesive have fine functions.

Because the vibration produced by emery wheel spindle system directly inflrences the processing precision of parts,a kind of monitoring circuit is designed for measuringthe vibration in tensity in this paper.
