Coatings: speed meets performance

A new circular arc technology has been developed for fast and reliable deposition of smooth tool coatings. Michiel Eerden, Product Manager at the Dutch PVD coating expert IHI Hauzer Techno Coating B.V.: “The technology is called CARC+ and has been tested by several toolmakers and job coaters with excellent results, outperforming other benchmark coatings.”

Before people buy a new car, they want to go for a test drive.This is now also possible for the new circular arc technology CARC+. Testing is believing!

“CARC+ is the abbreviation for Circular Arc Plus, an innovative technology with which tool makers are be able to distinguish their tools favourably from the ones of their competitors” says Michiel. One of the features of CARC+ technology is its fast cycle time. One batch will deposit a layer of 2 µm of AlTiN coating on the shaft of a tool (corresponding with approximately 3 µm on the cutting edge) in a cycle time of less than four hours.

Cost, quality, stability…
“With the new CARC+ technology, batch costs improved 44% compared with regular circular arc technology,” Michiel says. “Due to extremely high target utilization, the target costs per batch were even reduced with 83%. Furthermore, CARC+ improves the smoothness of the coatings considerably. For an AlTiN coating of 2 µm the Ra has been measured as low as 0.16 µm. The surface has fewer and smaller defects and is overall smoother. The technology has proven to be very stable.”

Successful results
Tool makers who have tested the technology achieved good results. Ball nose end mills coated with AlCrN; TiN coating on fluteless taps and shaft tools with TiAlN coatings; they all achieved significant improvements in performance, especially after longer cutting lengths. The technology is available on the Hauzer Flexicoat® 850, new or as an upgrade afterwards.

Opportunity to test customers’ production
Hauzer gives tool makers and job coaters the opportunity to test the new CARC+ technology by themselves on a Hauzer Flexicoat® 850 machine in their competence centres in Venlo, The Netherlands or Shanghai, China. They can use the machine for one week, of course supported by Hauzer process engineers. Michiel: “Cooperation is something we cherish and what better way to get convinced than to convince yourself.”

THe new technology by Hauzer can be discovered at EMO on Hall 3, Stand A28.
