Highly Efficient Methods of Machining Titanium for Oil-Gas Drilling Equipment

Resumo

A method is proposed for combined machining of difficultly machinable materials with precooling of blanks. It is demonstrated with reference to titanium and its alloys that high surface quality and assigned performance properties of the components can be ensured with retention of prolonged cutting-tool life by controlling heat fluxes during high-speed machining with precooling. For making tools, the most preferable are tool materials with a high heat conductivity coefficient.
