INCREASING THE DURABILITY OF THE CUTTING TOOL WITH A WEAR-RESISTANT COATING AFTER REGRINDING, BY GENERATING NANOSTRUCTURES OF LASER ABLATION IN THE LIQUID
In the process of processing products is inevitable wear of the cutting tool. There is partial wear or complete destruction of the cutting edges. The solution to the problem is the timely replacement or regrinding of the cutting tool. Regrinding of the tool is accompanied by the complete removal of the wear-resistant coating from the pads. After tool regrinding cutting conditions are reduced by 20-30% compared to the tool with a wear-resistant coating. In the article, based on the analysis of various methods of hardening treatment, a method is proposed to improve the resistance characteristics of the cutting tool after regrinding, by applying a nanostructure coating on the surface when irradiated with nanosecond laser pulses in a liquid.
