The Model 3110 Screwdriving Work-Cell is an ideal work station for semi-automatic assembly operations. This cell requires an operator to manually place the workpiece into a work holding fixture and to initiate cycle. This Cell can be fitted with several different screwdriver heads if required for specific driving requirements. The size of the vibratory feeder bowl is determined by size of the fastener. Appropriate operator guards such as light curtains sensors are selected because of the manual placement and removal of workpieces.
