MACHINE-TOOL AND CUTTING TOOLS PRODUCTION

Grishin Yu. A., Kuranov V. V., Malykh M. V., Gorbokonin N.V . — Research of the cutting tool coating for machining technology optimization of the gray irons SCh-20/25

The object of research was making a theoretical and practical model of relationship of temperature in a cutting zone of grey iron and coating material of the cutting tool.
There are temperature values of grey iron cutting carried out by two-cutter dynamic thermocouple method with use of cutters covered by TiN, ZrN, ZrTiN and without a covering, The calculations of temperatures values are executed using the Deform software at turning operation of grey iron feedwork. The received values of temperatures of cutting are correlated with the results received experimentally.
It is shown that TiN and ZrN coverings of cutting tool allows to reduce temperature in a cutting zone grey iron (and materials which properties are close to grey iron) in comparison with the tool without a covering or with ZrTiN combined covering.
Key words: cemented carbide tool, turning, two-cutter dynamic thermocouple, gray cast iron, TiN coating, ZrN coating, simulation, Deform

TECHNOLOGIES FOR OBTAINING PERMANENT CONNECTIONS

Boldyrev A. M., Gushchin D. A., Grebenchuk V. G. — Titanium dioxide interaction with a welding bath at automatic flux welding of the steel 10HSND with metal-chemical addition

The article presents investigations of interaction between electrochemical additive and a welding bath at machine welding of the 10KhSND steel under a layer of flux AN-47. Introduction of titanium dioxide with metal grainer into the welding bath favours formation of inclusions with high-melting nitride-titanium sheath. This prevents microvoids and crack formation in the weld metal, 20—25 % raises impact toughness of the weld material.
Key words: metal chemical additive, metal grainer, welding bath, titanium dioxide, crystallization centre
