TQ-3D Semi-Automatic Integrated Cutting & Grinding Terminal Cross-Section Analyzer
Product Overview
The TQ-3D is a semi-automatic precision inspection system specifically developed for quality control in the wire harness industry. Featuring a patented integrated cutting and grinding design, it consolidates precision sectioning, grinding, etching, high-definition imaging, and intelligent analysis into a compact unit. It can complete the entire process from sample preparation to analysis for a single terminal (up to 120mm²) in approximately 5 minutes. With user-friendly operation, Japanese optical components, and professional analysis software capable of automatic pass/fail judgment,it is an ideal tool for enhancing quality control efficiency on the production line.
Key Features
Integrated & Efficient Sample Prep: Utilizes a patented integrated cutting and grinding device to perform sectioning and grinding in one step, guaranteeing perfectly flat cross-sections and eliminating transfer errors.
Intelligent Analysis & Judgment: Built-in professional software automatically measures dozens of parameters including crimp height/width/radius, wall thickness, burrs, compression ratio, void ratio, wire count etc. and automatically calculates results against international standards to provide a pass/fail judgment, exporting a comprehensive Word report with data and cross-section images.
High-Definition Optical Imaging: Equipped with a 12-megapixel industrial camera and an Extended Depth of Field (EDOF) optical system, delivering clear magnified images from 45X to 512X for precise measurement.
Broad Compatibility & Coverage: Includes dedicated fixtures for various terminal sizes. The analysis range covers 0.01mm² to 120mm², meeting the inspection needs of wire harnesses across industries including home appliances, automotive, electrical, IT peripherals and rail transportation.
