An investigation of attritious and fracture wear of grinding wheels in precision grinding is described in a two paper sequence. Attritious wear, the subject of this first paper, refers to the dulling of the abrasive grain due to rubbing against the workpiece surface. The amount of dulling, measured by the area of the wear flats on the surface of the wheel, is found to be directly …

Grinding tools and grinding processes are no exception. The wear of grinding tools is an important factor in their grinding performance and affects the grinding process outcome strongly. Different wear mechanisms on the grit and bond level lead …

terms of energy requirements and steel consumption related to grinding media and liners. Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power

grinding includes snagging of castings/forging, tool sharpening, weld grinding, cutting off, bench grinding or pedestal grinding applications. Precision grinding is machine grinding where the traverse and or feed rates can be set and process parameters are measured and controlled. As the name indicates, here the need is

The "Touch probes" have been used for updating the wear of grinding stone, however, they cost very high, even it is a single detection of the grinding stone. The client is looking for contact-type sensors, as the grinding stone is stopped during the detection. Touch probes are expensive for wear updating of grinding stone.

This thesis involves the measuring of grinding wheel wear using an improved grinding wheel scanner. The positional resolution of the scanner has been improved from 26.5 μm to 0.65 μm with the addition of a second encoder. A vision based homing system was designed, and is able to track the position of the grinding wheel with a resolution of 2 μm.

Grinding is a precision machining method widely used in the precision manufacturing. Wears of the grinding wheel are common during the grinding process that would lead to the decrease of manufacturing precision. To improve grinding precision, a grinding wheel wear prediction method for multi-axis grinding is presented in this paper. Due to the complex shape …

The wear of Cubic Boron Nitride (CBN) grinding wheel directly affects the workpiece surface integrity and tolerances. This paper summarizes a combined experimental-modeling framework for CBN grinding wheel life expectancy utilized in both cylindrical and surface grinding.

Grinding tables have the features of high hardness, good anti-cracking. We carry out grinding table dressing and finishing machining by arc air gouging and shot-blasting, which can guarantee the quality of steel castings.

Belt grinding occupies a special position among abrasive techniques [].In kinematic and dynamic terms and in terms of the accompanying physical phenomena, this technique is intermediate between grinding by a rigid (practically undeformable) wheel [10, 11] and machining by free abrasive [].Grinding by a flexible abrasive tool is widely used in the auto industry, …

Abrasive belt grinding is the key technology in high-end precision manufacturing field, but the working condition of abrasive particles on the surface of the belt will directly affect the quality and efficiency during processing. Aiming at the problem of the inability to monitor the wearing status of abrasive belt in real-time during the grinding process, and the challenge of …

The nature and extent of grinding wheel wear in precision grinding were investigated directly from the wear particles removed from the wheel. A statistical analysis of the wear particle size distributions was developed to determine the relative amounts of bond fracture, grain fracture, and attritious wear. Most of the wear consists of grain and bond fracture particles with …
