■Features This machine (FM513VZ) allows for the adjustment of thrust (the force that presses the screw) according to the screw tightening process. Torque and speed settings can be configured individually, achieving optimal screw tightening based on material, hardness, thickness, and other factors, as well as the intended use and location. ■What is the thrust control function (patented)? This function performs ideal screw tightening close to manual tightening with the optimal thrust preset according to the type of screw and workpiece. ■What is different from a general-purpose single-axis robot + driver? Have you ever experienced difficulties in achieving proper screw tightening when trying to create a low-cost screw tightening device by combining commercially available single-axis robots and drivers, unclear responsibility from manufacturers, and ultimately not being able to meet equipment delivery deadlines, resulting in higher labor costs? Automatic screw tightening involves various factors such as screw shape and work material, making it far from simple. Using a commercially available general-purpose single-axis robot without careful consideration can lead to troubles. Our company, as a leading company in screw tightening, provides strong support with extensive experience and unique technology. ■Everything is made by our company All components, including the driver, lifting section, chuck section, screw feeder, and controllers, are manufactured by Nitto Seiko. Please consult us for special requirements.

Three elements required for fastening drill screws can be maximized!! ■Features■ 1) High-speed, high-quality fastening Our screw tightening machine's driver "KX Driver" has been improved to a drill screw-specific type, enabling a maximum high-speed rotation of 2000 min-1 during hole processing, and stable low-speed rotation with high torque control during thread formation and tightening, allowing for high-speed and high-quality fastening of drill screws. Settings can be customized according to conditions such as plate thickness and material. 2) Low inertia, high thrust During hole processing in steel plates, a stable thrust of 300 to 500 N (the force that presses the screw) is required. To achieve this, we have positioned the air cylinder on the driver bit axis, creating a structure that efficiently transmits thrust to the screw. Additionally, by reducing the weight of the lifting mechanism and re-evaluating the placement of the driver motor, we have minimized inertia, reducing the impact load on the workpiece during hole penetration. 3) Compact We have achieved a size reduction of 25% in width, 19% in depth, and 8% in overall length compared to conventional machines based on our general-purpose screw tightening machine. This increases the flexibility of the screw tightening machine layout, allowing for placement in narrow pitches (minimum pitch of 110 mm).

Solve the worry of loosening in self-tapping fastening to resin materials! "Giza Tight®" is a self-tapping screw for resin that utilizes the deformation of the counterpart resin material during self-tapping, providing a high loosening prevention function. By providing evenly spaced grooves along the vertical direction of the screw flange surface, the deformed resin during self-tapping wraps around the grooves, creating resistance against the reverse rotation direction and shutting out loosening. Especially under harsh environmental conditions such as expansion and contraction of the counterpart resin due to temperature changes and reverse rotation caused by vibrations, it exhibits tremendous loosening prevention performance due to mechanical elements (the wedging effect from the resin wrapping around the grooves). 【Features】 ■ Grooves at four locations on the outer circumference exhibit loosening prevention effects ■ Asymmetric screw threads prevent boss cracking ■ Usable with a wide range of resin materials *For more details, please download the PDF document or feel free to contact us.
