As a well-known Chinese brand in the field of heavy-duty hard cutting, Valin CBN tools solve the problem of low processing efficiency of large high hardness wear-resistant castings (high chromium cast iron pumps, high manganese steel wear-resistant parts, etc.), and better achieve the balance of wear resistance and impact resistance compared with other CBN tools in the industry. In China, South Africa, Peru, Chile, India, Brazil, Australia, Thailand, Russia, Vietnam, Pakistan and other countries used in the processing of mining wear-resistant castings and received high praise.
