The biggest challenge in automatic screwdriving isn’t speed or torque accuracy: It’s getting the fastener to the tool reliably and oriented correctly. Fortunately, assemblers have several options for feeding screws to fully or semiautomatic drivers, including screw presenters, bowl feeders and step feeders.
Threaded fasteners are, by far, the most common method of assembling parts. According to ASSEMBLY magazine's annual Capital Equipment Spending Survey, screwdriving is performed at 58 percent of U.S. assembly plants, making it more popular than welding, pressing, adhesive bonding or riveting.
Sooner or later, most manufacturers need to consider investing in automatic screwdriving equipment. If an assembly calls for multiple screws of the same size, an autofeed screwdriver is an easy way to boost accuracy, productivity and quality.
