Lapping Polishing Machine(Small-Scale )

Lapping Polishing Machine(Small-Scale )-FC-Steel-2

Compact in size, high in efficiency—an ideal choice for steel plate regeneration!

Developed in-house by FINE CAUSE, the FC-Steel-2 combines semiconductor-grade polishing techniques with practical engineering, making steel plate regrinding fast and cost-effective.

Suitable for a wide range of materials, including:

SKD11 heat-treated plates, ceramic components, sapphire, mobile device parts, watch glass, tungsten carbide, silicon, and more.

Key Design Features:

Wet lapping system design

Closed-loop slurry flow helps maintain stable platen temperature and avoids deformation caused by overheating.

720mm Platen Diameter

Can accommodate up to four 90×200mm or two 120×240mm plates (depending on work ring configuration).

Four Pneumatically-Driven Work Rings

Allow for flexible single, dual, or quad-piece operation—either in sync or independently.

Adjustable Motion & Intelligent Controls

• Multiple motion modes: synchronized, sequential, and individual control

• Customizable delay time and reciprocation count

• Independent stroke settings for each work ring

• Each part rotates via an individual small AC motor (single-phase 220V), with stepless speed adjustment

User-Friendly HMI Panel

• 7” touch screen (Weintek MT8071iE) supporting Traditional Chinese, English, Vietnamese, Indonesian, and Thai

• Real-time display of machine status and parameter settings

• Manual component testing, sensor monitoring, and timeout alarm features

Patented Design Advantages

• Pneumatic push-ring system reduces manual error and mechanical wear

• Detachable abrasive modules for easy maintenance and quick replacement

• Multi-point displacement structure avoids localized platen wear

• Optional polishing pads and diamond lapping film available for multi-stage processing

Importance of Pressure Application Methods in Lapping and Polishing Performance

Common pressure application methods currently include: pneumatic pressure systems and weighted block pressure systems.

✅ Custom Pneumatic Pressure System (Suitable for High-Precision Material Processing)

Pneumatic pressure systems provide stable and uniform pressure, making them especially suitable for high-precision workpieces such as electronic components and semiconductor substrates.

📌 Advantages: Precise and controllable pressure, ideal for mass production and quality inspection analysis
 

✅ Weighted Block Pressure System (Suitable for General Parts and Custom Thickness Applications)

Standard equipment commonly uses a weighted block pressure system. Different thicknesses and weights of pressure blocks can be flexibly selected according to the workpiece weight and processing requirements.

📌 Advantages: Simple structure, high flexibility, and easy maintenance
 

Applicable Materials & Workpieces

• Metals: Cast iron, copper, aluminum, alloy steel, high-carbon steel, platinum, gold, silver, etc.

• Non-metals: Glass, silicon, quartz, rubber, plastic, marble, ceramic, and more

Application Examples:

• SKD11 plate regrinding (extending tool life)

• Precision valve plates, water-stopper valves, wafer components

• Compressor and refrigeration components

Typical 3-Stage Lapping Process (e.g., for pad printing plates)

• 1️⃣ Rough Grinding: Surface imperfections removed using a wheel-based surface grinder

• 2️⃣ Fine Grinding: Wet lapping using diamond slurry for surface refinement

• 3️⃣ Mirror Polishing: Achieve ultra-flat, glossy finish with polishing pad and compound

⚠️ Most industries stop at stage two, but high-spec industries such as contact lens mold making and semiconductors require final-stage mirror polishing.

Fine Cause uses the FC-Steel-3 automatic lapping and polishing machine / wet grinding equipment together with FUJIMI Green Silicon Carbide for surface grinding, allowing pad printing steel plates to be reused with new patterns, effectively extending plate life and reducing costs.
