TURNING INSERT
Sure! Heres the English translation of the provided technical text:
---
ZCC turning inserts are typically manufactured from tungsten carbide alloy with an approximate density of 14.5 g/cm³ and coatings such as PVD TiAlN or CVD TiCN. The insert thickness ranges between 3.18 to 6.35 mm and the nose radius varies from 0.4 to 1.2 mm. The positive rake angle is designed between 7 to 15 degrees to ensure smooth cutting and reduce vibration. ZCC inserts comply with ISO and DIN standards, allowing compatibility with various tool holders. The precise material composition enhances hardness up to approximately 92 HRA, contributing to stable performance at high cutting speeds.
The optimal cutting speed range for ZCC turning inserts on alloy steels is between 180 and 450 meters per minute. The typical feed rate is set between 0.1 and 0.35 mm/rev. Common geometries include CNMG, SNMG, and WNMG, designed with optimized angles for improved chip evacuation and reduced heat generation. Under proper cooling conditions, tool life can exceed 120 minutes. ZCC’s multilayer coating structure guarantees high resistance to wear and corrosion.
