One of the most impressive material characteristics of cemented carbide is its stiffness compared to steel. This property is expressed in engineering terms as Modulus of Elasticity or Young's Modulus. All steel materials have a Young's Modulus value of 30,000,000 psi whereas cemented carbide has a value of 94,000,000 psi. Thus, carbide is 3 times more rigid or "stiffer" than steel. No other application takes better advantage of this distinguishing physical property than a boring bar application. The boring bar must extend inside a cylinder's bore or inside diameter for extreme lengths while performing a metalcutting operation with minimal deflection so as to reduce chatter and vibration. General Carbide has many years of experience in producing boring bar blanks with proper material characteristics and high quality to perform in this application. We can produce an as-sintered blank or a blank with a ultility grind to make it easy for our customer's final finishing operations and brazed attachments. |  |
