Titanium alloy Ti-6Al-4V (Grade 5) is a cornerstone material in aerospace, medical, and energy sectors due to its exceptional strength-to-weight ratio and corrosion resistance. However, its machining challenges—low thermal conductivity, high chemical reactivity, and work hardening—demand meticulous optimization of cutting parameters. This article dives into the "golden ratio" of speed, feed, and depth of cut […]

The point angle of a drill is a critical geometric parameter that directly dictates cutting performance, chip formation, tool life, and hole quality in metal machining. Selecting the optimal angle is contingent on workpiece material properties (hardness, ductility, toughness), hole requirements (precision, depth, surface finish), and machining conditions. This article dissects the three most common […]

If you're in the business of metal cutting—drilling, milling, turning—you know the coating on your tool isn't just a fancy finish; it's its armor. It’s what stands between a sharp, productive edge and a worn-out, expensive piece of scrap. The two heavyweight champions in this arena are Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). While both […]

1. Introduction Milling cutters are core tools in machining, and their performance directly determines processing efficiency, workpiece quality, and production costs. Plastic deformation and rapid flank wear are two common and costly issues in milling operations. These problems not only shorten the service life of the cutter but also lead to poor surface finish of […]
