Hard part turning with CB7105 and CB7115
Hard part turning is usually a finishing or semi-finishing process with high dimensional accuracy and surface quality requirements.
Sandvik Coromant's new grades CB7105 and CB7115 break new ground in hard part turning. The new grades are based on the newest generation Cubic Boron Nitride (CBN) material. This material enhances crater wear resistance and fracture resistance at high cutting speeds in case hardened and induction hardened material.
BIDEMICS all the buzz at NTK Cutting Tools
During a brief interview at IMTS 2018, Steve Howard, marketing and engineering manager for NTK Cutting Tools, discussed the significance of the company's patented BIDEMICS material, calling it "the first real improvement in ceramics in 20 or 30 years."
Chatting with Cutting Tool Engineering Publisher Dennis Spaeth, Howard said BIDEMICS makes it possible to increase cutting speeds in heat-resistant alloys by 17 times over carbide. The new composite material reportedly is capable of running at 1,600 sfm to 1,700 sfm.
