The above review of the current research status of whetstone from the aspects of whetstone molding (raw material and process), whetstone performance evaluation methods, rail burns, etc., summarizes that the design and manufacture of whetstone is a multidisci...

One of the main drawbacks of domestically produced grinding stones at present is the tendency to burn steel rails [1]. During the process of rail grinding, the grinding effect of abrasives (sliding, plowing, cutting) and the friction between the binder and rai...

Grinding stone commonly used abrasives for corundum class abrasives (zirconium corundum, brown corundum, white corundum, etc., such as Figure 11)[1,2] , some super-hard abrasives (CBN)[3] and SiC, WC, etc. Because diamond and transition metal element Fe has st...

The binding agent plays a pivotal role in securely bonding abrasive particles, thereby ensuring that the grinding stone possesses crucial mechanical properties such as strength, toughness, wear resistance, and heat resistance. It also provides the necessary ho...

Grinding Stone Performance Evaluation Method The most crucial aspect of the grinding stone development process lies in evaluating and verifying its performance (including size and accuracy, dynamic/static balance, rotational strength, load-bearing capacity, g...

Regular rail grinidng reduces or removes rail damage and extends their service life, which is widely recognized as one of the effective maintenance methods in rail transit systems. Based on the behavior of rail damage and combined with the needs of railway tra...

Rail grinding is a process of material removal by rotating grinding wheels. The grinding mileage is quite long, using cutting fluid will not only increase the maintenance cost, but also cause widespread pollution.  

At Guilin West Station in Guangxi, the Hasco PGM96C rail grinding car is busy carrying out rail grinding operations. This equipment ensures the smoothness and safety of railway tracks with its efficient operational capabilities. In this assignment, Fashan brand grinding wheels were used, which are widely recognized for their wear resistance and excellent grinding performance.

Grinding is a machining process which an abrasive grinding wheel (GS, as given in Fig.1) is utilized to remove materials at a certain rotating speed [1]. The grinding wheel is composed of abrasives, binding agent, fillers and pores, etc. In which, the abrasive plays a role of cutting edge during the grinding process. 

At the Qijiang Station interval in Chongqing, 12-head grinding machines are using Fasan brand grinding wheels for rail grinding operations. This operation is crucial for maintaining the safety of railway tracks and extending the service life of the rails. By precise grinding, irregularities and wear on the rail surface can be eliminated, thereby reducing noise and vibration during train operation and improving passenger comfort. Regular grinding operations also help prevent premature fatigue and breakage of the rails, ensuring the continuity and reliability of railway transportation.
