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.
