Final Fastening Process Overview

The document outlines the stages and parameters involved in the final fastening process, including initial fastening torque, screw head seating, rotation speeds, and timing. Key phases include initial rotation (idle rotation), tap forming, screwing, and final fastening, with emphasis on monitoring torque output and shaft rotation speed throughout these stages.

Key Parameters and Procedures

Initial Fastening Torque: The torque applied during the initial fastening phase before final tightening.
Screw Head Seating: The stage where the screw head is seated properly before final torque application.
Rotation Speeds: Different rotation speeds are specified for initial rotation, tap forming, and final fastening to ensure proper screw engagement and torque accuracy.
Torque Output Monitoring: Continuous monitoring of torque output and shaft rotation speed is critical to verify fastening quality.

Mechanical Specifications and Compatibility

The document provides detailed mechanical specifications for various models and tool units, including mounting flange compatibility, screw thread types, and dimensions.

Mounting Flange and Screw Details

Compatible mounting flanges for 4-M5 screws with 20 x 44 pitch.
Various screw sizes and thread types such as M3, M5, M8, and M10 (notably M10 female thread for NX800T2 only).
Dimensions for screw depths, flange sizes, and spacing for wiring are specified for different models.

Model and Tool Unit Specifications

Models covered include TU series, KX series (KX050T2, KX100T2, KX150T2, KX400T2), NX series (NX008T2, NX020T2, NX050T2, NX100T2, NX180T2, NX250T2, NX500T2, NX800T2), and their respective tool units.
Output shaft types selectable as M (M8 female thread), S (square shank), or H (hex hole), with some models limited to M or H only.
Length and dimension details for each model and tool unit are provided, including total length, shaft diameter, and space for wiring.

Controller and Power Unit Options

Compatible controllers include SD550T, SD550, and SD600T.
AC power units or switch units are available as optional components.

Critical Dimensions and Mechanical Features

The document includes precise mechanical dimensions such as flange diameters, screw hole depths, shaft diameters, and spacing for wiring. These are essential for ensuring proper installation and compatibility across different models and tool units.

Examples include flange hole spacing (e.g., 20 x 44 pitch), screw hole depths (e.g., 7 mm for M3 screws), and shaft diameters (e.g., φ32, φ36).
Special notes such as two-side width measurements and specific thread types for certain models are highlighted.

Summary of Best Practices and Recommendations

Maintain specified rotation speeds during each fastening phase to ensure accurate torque application and screw engagement.
Monitor torque output and shaft rotation speed continuously to detect any anomalies during fastening.
Use compatible mounting flanges and screw types as per model specifications to avoid mechanical incompatibility.
Select appropriate output shaft type (M, S, or H) based on the model and application requirements.
Ensure proper wiring space and controller compatibility for seamless integration.
