Comprehensive Analysis of Milling Cutter Panel Splitters: Core Technology, Industry Applications, and Zhimao Technology’s Vietnam Customer Case

I. Working Principle and System Overview of Milling Cutter Panel Splitters

As a critical piece of equipment in modern electronics manufacturing, the milling cutter type panel splitter excels in precision panel separation applications due to its unique operating principle. This device employs an innovative dual-slide rail and pneumatic cylinder dual-platform coordination mechanism, achieving automated operation through a precision CNC system. During operation, it can simultaneously process two different specifications of PCB panels, effectively resolving the efficiency bottlenecks caused by single-platform designs in traditional panel splitting equipment.

Seprays’s independently developed GAM-320 series milling cutter depanelizer further optimizes performance by upgrading the dual-platform design to a switchable mode. It can operate as an independent dual-station setup or convert to a large-size single-station configuration, supporting maximum processing dimensions of 350×300mm. This significantly enhances equipment adaptability and production flexibility.

II. Detailed Analysis of Core Advantages

1. Precision Stress Control Technology

Equipped with a Swiss-made high-speed electric spindle offering stepless speed adjustment from 0-60,000 RPM, the machine employs Seprays’s proprietary stress control system to maintain cutting stress below 150μɛ. This effectively prevents component damage and solder joint cracking, ensuring zero damage to sensitive components during the de-panelization process.

2. Intelligent Tool Monitoring System

Incorporating Seprays’s patented tool health monitoring system, it utilizes multi-sensor data fusion technology to collect real-time spindle load, vibration frequency, and temperature data. Upon detecting tool abnormalities, the system automatically shuts down within 50ms for protection and alerts operators via audible and visual alarms, significantly reducing product scrap rates caused by tool breakage.

3. Advanced Vision Positioning System

Utilizing a high-resolution CCD camera paired with an intelligent ring light system, featuring 256-level brightness adjustment and automatic white balance. This system precisely identifies mark points on various special-process boards, including highly reflective gold-plated boards, dark-colored immersion gold boards, and PCBs with diverse surface treatments, achieving positioning accuracy of ±0.01mm.

III. Primary Application Industries

The milling cutter depaneling machine finds extensive application across the following sectors due to its high precision and low-stress characteristics:

– Automotive Electronics: Manufactures critical components such as engine control units, in-vehicle infotainment systems, and ADAS (Advanced Driver Assistance Systems), meeting the stringent reliability demands of automotive electronics.

– Medical Device Industry: Used for circuit board separation in precision medical equipment like pacemakers, medical monitoring devices, and portable medical instruments, ensuring compliance with medical-grade quality standards.
