1. Tool change time = $195,000
The incumbent tooling and gang plate were quite outdated and required a tool change time of nearly 25 minutes twice per day for each of the 4 tools in the gang.
This resulted in 3 hours of spindle down time per shift! Once the AFC system was installed the tool change times immediately fell to 30 seconds for each tool, thus reducing spindle downtime to a mere 8 minutes per shift.
2. Tool life and increased parameters = $479,500
Adopting ARNO's through coolant tool holders with insert grades and geometries that were designed specifically for high production applications had a profound impact on productivity. Tables were submitted in the document that showed time reduction in turning, grooving, and parting operations with some process times being reduced by 75%.
Of course, the through coolant feature increased tool life which further reduced the need for spindle idle time. This total revenue bump was calculated using 325 hours of increased spindle uptime per month. That's nearly 4000 hours of productivity gained annually... which resulted in another big advantage: The customer was able to bring subcontracted jobs back in house.
At ARNO USA we love combining our years of manufacturing experience with game changing innovative technology to make huge impacts on our customers' productivity, accuracy, quality, and process stability. The ARNO FAST CHANGE program is pretty vast with new additions coming on line on a regular basis. There are nearly 50 gang plates presently available for the following machine manufacturers: Citizen, Star, Hanwha, DMG, Nexturn, and Tornos!
