Experimental Study on the Cutting Performance of Cemented Carbide Rods Made by New Process

摘要

Cemented carbide rods, which are mostly made by powder extrusion molding, are workblank for various cutting tools. In this paper, new cemented carbide rods, namely GU20, were made by new optimized process, and were manufactured into uncoated and coated cutting tools to evaluate their cutting performance. Experiment results showed that the uncoated and coated tools made of the new cemented carbide rods had better cutting performance than those made of the old rods made by old process.
