PCBN Cutting Tools in the Air-Conditioning Compressor Industry

Typical parts of an air conditioning compressor that can be machined using PCBN cutting tools include flanges, cylinders, and crankshafts. The material is a gray cast iron. The service life of our PCBN cutting tools are 5-10 times longer than coated carbide tools, and are 1-3 times as efficient.

About the Customer
The customer is a refrigeration equipment manufacturer based in Guangzhou. Due to the serious discontinuity of flange processing, the cutting tool was damaged quickly by the impact. The coated carbide tool requires frequent replacement, which results in a rising cost. In addition, the replacement of cutting tools takes time and lowers production efficiency. PCBN cutting inserts from other companies ended up chipped or broken.

Customer Feedback
Since we started using Funik's PCBN cutting inserts, we have only needed to replace the inserts once per shift. It works 4-6 times longer than that of cutting tools from other suppliers. The speed is also increased from 800 r/minute, to 1200 r/minute., and the production efficiency has been increased by more than 50%.
