Description
Product Overview
Polycrystalline Cubic Boron Nitride (PCBN) cutting tools are the ultimate solution for machining ferrous materials — hardened steels, alloy steels, tool steels, and cast irons. Unlike diamond, which chemically reacts with iron, PCBN maintains its cutting edge integrity when machining ferrous metals at high temperatures.
SINO SEIKO（Sino Qtech Industries Co., Ltd.） supplies a comprehensive range of PCBN cutting tools including solid PCBN, carbided PCBN, and PCBN inserts. Our tools are manufactured from micron-grade CBN powder sintered under ultra-high pressure and high temperature (HPHT), ensuring consistent quality and performance across every batch.

Key Advantages
🔥 High Thermal Stability
Stable up to 1,400°C — ideal for dry machining of hardened steels and cast irons.
⚙️ Hard Turning
Replace grinding with hard turning — faster, cleaner, and more cost-effective for hardened components.
🛡️ Ferrous Compatible
Unlike diamond, PCBN doesn’t chemically react with iron — perfect for steel and cast iron machining.
