NITTOSEIKO CO., LTD. Product Lineup

Single-axis screw Driving machine that can tighten screws with "ultra-low thrust". Prevents defects such as seizing and misalignment that could not be avoided with conventional screw tightening automation. Also, reduces the load onto the workpiece. By minimizing the deflection of the workpiece, it also contributes to improve the accuarcy of screw float detection. 【Features】 1. By offsetting the weight of the driver unit against push down thrust (weight cancellation function), the thrust during tightening is reduced by approximately 70% compared to conventional machines. This prevents issues such as seizing and misalignment caused by excessive thrust. Furthermore, it allows for gentle tightening on the workpiece, reducing deflection and contribute to improve the accuracy of screw float detection. 2. 《Reduce Cycle Time》 By advanced motion control system, remarkable cycle time reduction has been achieved. The increased speed of the driver unit brings great improvement, especially in processes of long tightening strokes. *For more details, please download the PDF or feel free to contact us.

"Screw Tightening Machine with Ultra-High Precision Screw Floating Detect Function" is a product that solves issues such as the risk of screw floated products being shipped out, or the burden of complecated screw float inspection work. The system re-learns the relative distance between the bit and the screw seating surface every time a screw is supplied from the feeder. Re-teaching after bit replacement is no longer required, and even slight screwfloating can be detected. Perfectly suitable for automotive components. [For these issues] ■ Dimensional variations of screws caused by manufacturing tolerances. ■ Dimensional changes of the bit caused by wear. *For more details, please download the PDF or feel free to contact us.

In the automotive industry's quality assurance, proper tightening of screws is essential for ensuring product safety and reliability. Particularly for automotive parts exposed to vibrations and impacts, loosening or breaking of screws can lead to serious accidents. Our internal threads inspection robot automates the inspection after internal threads processing, contributing to improve accuracy in quality control. 【Application examples】 - Quality control departments of automotive parts manufacturers - Sampling inspections on the manufacturing line - Quality evaluation during the prototype stage 【Benefits of Implementation】 - Increase efficiency and accuracy of inspections - Cost reduction through early detection of defective products - Improvement in product quality and customer satisfaction
