CASE STUDY LARGE SCALE AEROSPACE PARTS MANUFACTURER
When Mountz approached the company, the primary question Rob Ralph, Mountz sales manager asked was, “What if you could work faster and smarter by increasing your screwdriver RPM and reducing the risk of cross- threading?” For any assembly operation, when you’re approached with opportunities to boost productivity and improve quality, you have to investigate. Solutions ADJUSTABLE RPM ELECTRIC SCREWDRIVERS WITH SOFT START TECHNOLOGY Previously, they were using a 750RPM driver. Mountz proposed transitioning to the E-DRIV® NF-220 Brushless Electric Screwdriver that offers adjustable speeds ranging from 700 to 1,200 RPM. With 40% higher RPM capacity, assembly speed could be increased, while reducing the risk of cross-threading in the first few turns by using the device’s soft start feature. With soft start, the tool is powered at 30% operating RPM during the first .2-.6 milliseconds until the first 2-3 threads are engaged. This helps reduce or eliminate the risk of cross-threading. The tool also gave them the flexibility to adjust RPM in 50RPM increments to fine tune the operations. Additionally, the company decided to add the Scout II Screw Counter to the NF-220 to eliminate the risk of improperly seated or missing fasteners, as well as a dynamic rotary torque sensor for inline torque testing. This allowed them to capture torque data over time to better apply quality control procedures
“ When you think about productivity and quality you have to look at the full picture to find the right tool. A smart investment upfront can help you maximize the capacity of your existing lines, respond to spikes in demand more effectively, and reduce waste or
rework. ” Rob Ralph, Mountz Sales Manager
