INCREASING ENVIRONMENTAL SAFETY OF WORKERS 'LIFE IN PRODUCTION CONDITIONS ON TECHNOLOGICAL OPERATIONS OF DIAMOND GRINDING

Abstract

The paper substantiates the main directions of improving the environmental safety of workers' life in production conditions at technological operations of diamond grinding by using environmentally friendly technology of electro-erosion restoration of diamond wheels on high-strength metal bonds. It is shown that this technology, in contrast to the traditional technology of abrasive dressing, excludes the formation of abrasive dust at the workplace, and, in contrast to electrochemical dressing, excludes the use of strong electrolytes. Instead, ordinary industrial water is used. However, in the process of electro-erosion reduction, sparking occurs in the processing zone, which is undesirable for a worker with a long dressing time. Therefore, a new technical solution is proposed in the work, which consists in using a manual insulated electrode, which provides short-term electro-erosion restoration. This virtually eliminates the negative impact of sparking on the worker's organs of vision. On this basis, practical recommendations have been developed for the creation of environmentally friendly technologies for grinding with diamond-abrasive tools on metal bonds of products made of difficult-to-machine materials (hard alloys, natural diamonds, ceramics, ferrites, etc.) This, firstly,  allows the manufacture of competitive industrial products and, secondly, it improves the environmental protection of the workplace and production in general, increases the safety and efficiency of the worker.
