Metalloinvest launches unique crushing
and conveyor complex at Mikhailovsky
GOK Metalloinvest, a leading manufacturer and
supplier of iron ore products and hot briquetted
iron in the world market, one of the regional
producers of high-quality steel, has implemented
it at the Mikhailovsky Mining and Processing Plant
named after A.V. Varicheva advanced conveyor
technology for transporting ore from a quarry.

NEW TURNING GRADES FOR CAST
IRON AND CAST STAINLESS STEEL
Mitsubishi Materials has expanded its comprehensive
range of premium insert grades for turning. BC5110 is
a specially coated CBN specifically for machining grey
cast irons such as GG25 and GG30. Whereas the MH515
grade is a CVD coated carbide grade designed for cast
austenitic stainless steels as well as ductile cast iron.
The new BC5110 delivers a variety of performance and
benefits by drawing on the vast R&D work built up over
years of producing other high performance CBN grades.
This work has created a composition of a fine grain, high
CBN content substrate that greatly improves chipping
resistance. This results in process reliability and longer
tool life. Meanwhile, the hard ceramic coating layer
adds to the user benefits by providing wear and notching MH515
