[en] High performance, brittle materials are the materials of choice for many of today's engineering applications. This paper describes three separate precision grinding processes developed at Lawrence Liver-more National Laboratory to machine precision ceramic components. Included in the discussion of the precision processes is a variety of grinding wheel dressing, truing and profiling techniques

[en] The article presents the results of testing a prototype vibro-grinding laboratory machine for making samples for metallographic examination. The effectiveness of the method and its suitability for the preparation of thin sections during laboratory studies in the discipline “Material Science” have been established. (paper)

[en] The use of level monitoring devices and safeguards against overfilling are described, with particular reference to the choice of the monitoring points rather than to the function of the equipment employed (microwaves, ultra-sonic measurement, gamma rays). (orig.)

[en] Some ferrous metals have been ground under different conditions with high-speed and speed-stroke in surface grinding operation. The paper describes experimental investigation of grinding forces in grinding some ferrous metals with the application of cutting fluids. Grinding tests have been carried out on mild steel, assab steel and stainless steel with different combinations of down feed and cross feed. The wheel speed was 27 m/sec while the table speed was maintained at the maximum possible 25 m/min. The grindability has been evaluated by measuring the grinding forces, grinding ratio, and surface finish. Grinding forces have been plotted against down feed of the grinding wheel and cross feed of the table. It has been observed that the radial and tangential grinding forces in stainless steel were higher than those in assab steel and mild steel

[en] New designs of cover plates and grinding plates for a universal grinding machine are developed. These designs greatly expand the functional capabilities of the machine. The plates are durable and their operating costs are low.

[en] In view of the lack of relevant research on CNC grinders in the field of reliability research of CNC machine tools at present, This research collected reliability data based on 19 MSK series grinder machine tools of a machine tool factory., found out the crucial subsystem which is the most important component to the whole, and analyzed the reliability of the subsystem adopting FTA (Fault Tree Analysis) . Statistical researched on 438 reliability data collected, combining with the actual production situation, the results shows that cooling system is the key to the reliability of the whole grinder machine tool. The 29 minimum cut sets obtained by FTA can be adjusted to improve the reliability of the cooling system, what is more, the reliability of grinder machine tool would be improved as well. (paper)

[en] The use of a highway grinding unit for the decontamination of a 5,000 square foot surface is described. The type of equipment presently in use is described. Performance characteristics, waste collection and water usage are commented on. Variables in blade design are discussed. Feasibility of the grinding technique for water soluble contaminants and vertical surfaces is referred to
