GAM386 Offline Bottom-Cutting PCB Depaneling Machine

Description

The SEPRAYS GAM386 is a high-performance offline bottom-cut PCB depaneling, designed for manufacturers requiring precision, speed, and flexible PCB depaneling. Ideal for taller components and high-mix production, the system delivers reliable performance while minimizing downtime.

Dual Worktables for Maximum Efficiency

Equipped with dual platen work platforms (300 × 350 mm each), the GAM386 enables simultaneous loading and cutting to reduce waiting time and maximize throughput. The tables can also be combined into a single large platen (620 × 350 mm) for oversized boards, providing versatile operation for a wide range of PCB sizes.

Bottom-Cutting for High Components

The bottom-cutting design safely processes PCBAs with tall top-side components, reducing mechanical stress and preventing damage to sensitive assemblies. This makes it perfect for high-density and complex PCBs.

Precision and Automation

A high-speed CCD vision alignment system ensures accurate positioning for every cut, while a precision screw-driven worktable delivers stable, high-accuracy movement. The auto tool-change spindle minimizes manual intervention and reduces production downtime.

Safety and Integration

With no platen entry or exit during operation and an optional light curtain, operator safety is maximized. The system supports robotic arm I/O points for integration into automated workflows. Additional options include milling tool diameter detection, a handheld barcode reader, and custom MES connectivity for smart manufacturing.

Proven Reliability

Trusted by top global brands, the GAM386 PCB depaneling combines robust hardware, intelligent software, and advanced dust management to ensure stable and high-yield operation.

Q1: What is the maximum PCB size the GAM386 can handle?

The dual platen setup handles 300 × 350 mm each, or can be merged into a single 620 × 350 mm platen for larger boards.

Q2: Can it process PCBs with tall components?

Yes, the bottom-cutting design supports top-side components up to 45 mm, ensuring safe separation without damage.

Q3: How does the CCD vision system improve accuracy?

The high-speed CCD automatically detects reference points and board edges, performing real-time positional correction for precise cuts.

Q4: Is the machine suitable for high-mix or low-volume production?

Absolutely. Dual worktables and offline programming allow fast changeovers, making it ideal for high-mix, low-volume, or prototype production.

Q5: What safety features are included?

No platen entry or exit, optional light curtain, and robotic I/O points enhance operator safety and line integration.

Q6: How is milling tool life managed?

The patented floating brush allows multi-stage cutter usage, and software monitors cutter height, slippage, and breakage to prevent damage.

Q7: Can the machine integrate with MES or other automated systems?

Yes. Optional MES connectivity and robotic I/O points enable seamless integration into automated workflows.

Q8: How is dust handled during cutting?

Equipped with a high-power dust collector and HEPA filtration, combined with negative pressure monitoring and a floating brush for enhanced efficiency.
