Case Study

Cargo Plane Floor

SUCCESS STORY
The customer makes parts (cargo plane floors) and couldn’t get access to drill the approximately 380 holes in diameters of 2.5 and 6 mm, so the operation time was 4:30 hours. We used the Micro 90° with AIR drive to machine the difficult to access parts for other types of tool and could reduce the operation time by 67% to 1:30 hours.
