SD300-WJS+2D/3D Series – Precision Automotive Deburring & Polishing System for High-Speed Stamping Lines

“What You Don’t Finish Properly, You’ll Fix Expensively Later.”

Ask any automotive QA manager: bad paint adhesion always leads back to poor surface prep.
And in stamping lines pushing 10,000+ parts/day, manual deburring simply can’t keep up—or stay consistent.

That’s where the SD300-WJS+2D/3D Series steps in.

Engineered for high-volume, high-precision finishing, it ensures that each stamped steel or aluminum component is burr-free, oxide-free, oil-free—and coating-ready.

“Stamping is about speed. Finishing is about control.”

The Problem with Most Automotive Deburring Solutions

High-speed stamping causes:

• Micro-burrs around holes and flanges

• Oxide buildup from thermal effects

• Embedded oil residues from lubricants

These lead to:

• Peeling at corners after coating

• Poor plating durability

• Increased warranty claims due to surface defects

In my own experience supporting Tier 1 suppliers in North America, I’ve seen powder coating reject rates drop over 70% just by switching to automated burr + oil removal systems.

What Makes This System Different?

1. Wide Abrasive Belt Deburring Head

• High-pressure belt removes primary burrs, weld spatter, and surface scale

• Prepares a clean surface for brushing and polishing

2. 2D/3D Disc Brush Polishing Heads

• Flexible brush arms adapt to part contours

• Smooths edge transitions and internal holes without rounding flat planes

3. Automated Batch Feeding

• Conveyor-driven workflow supports continuous feeding from stamping press or buffer rack

• Vacuum table or magnetic rollers ensure small parts stay aligned

4. Intelligent Control Panel

• Preset programs for steel, aluminum, or coated parts

• Real-time adjustments for brush pressure, rotation speed, and belt wear

Applications – From Bumper Brackets to Sensor Shields

This system is currently deployed in plants manufacturing:

• Suspension and chassis mounting brackets

• Transmission support frames

• Electronic control unit (ECU) housings

• Sensor and camera housings

• Decorative trims requiring scratch-free edges

Materials handled:

• High-strength steel

• Hot-dip galvanized sheet

• Aluminum alloy (5000/6000 series)

• Stainless (304, 430) with protective films

Real-World Results – Case Study: Tier 1 Supplier in Central Europe

Problem:
Manual grinders couldn’t consistently finish complex punch-outs on structural brackets. Paint adhesion failures in salt spray testing caused rework and customer dissatisfaction.

Solution:
Installed SD300-WJS+2D with dual brush configuration and oil mist filter.

Results after 90 days:

• Coating failure rate dropped from 11.5% → 1.2%

• Grinding-related injuries: 0

• Paint yield improved from 82% → 96.7%

• Annualized rework cost savings: €78,000

Summary – This Isn’t Just About Removing Burrs. It’s About Building Trust.

Key Takeaways:

• 3-in-1 process: burr removal + oxide elimination + edge polishing

• Reduces dependency on manual labor and improves safety

• Increases coating yield and plating bond strength

• Handles complex shapes with flexible brush systems

• Fits into lean, high-output production environments

“Quality isn’t inspected into a part. It’s engineered from the first burr.”

If you’re still using angle grinders in a 10,000-unit production line—you’re not automating. You’re improvising.

Your Opinion Counts – Where Do You Stand?

✅ Do you believe manual grinding still has a place in automotive production?
✅ Or should robotic + automated systems handle the finishing phase entirely?
✅ What’s your take on coating defects—powder problem or prep problem?
✅ Would you trust a line that doesn’t control surface roughness before painting?
