FC-Steel-3 Automatic Lapping and Polishing Machine (Medium Type Wet Lapping Equipment)

Multi-Workpiece Precision Processing × Adjustable Work Rings × High-Efficiency Mirror Polishing

FC-Steel-3 is designed specifically for medium-sized workpieces and supports wet precision lapping and polishing of various metal and non-metal materials. It is ideal for applications such as SKD11 steel plates, ceramic components, wafer and chip materials, and aluminum parts, ensuring excellent flatness and surface roughness control.

 

Wet lapping system design

  • Circulating slurry system: The slurry is automatically circulated to maintain stable lapping plate temperature, effectively preventing workpiece deformation caused by excessive heat.

  • 800 mm worktable diameter: Supports maximum workpiece size up to 480 × 280 mm (depending on the selected work ring configuration).

 

  • Four adjustable work rings: Flexible setup for single-piece, dual-piece, or four-piece simultaneous processing.

 

Multi-motion modes and control features

  • Adjustable processing parameters

  • Three work ring movement modes: synchronous, alternating, and independent operation

  • Customizable dwell time and reciprocation cycles

  • Worktable rotation speed adjustable as needed

 

Adjustable work rings

Configuration: Four work rings in total, each driven by a cylinder to achieve reciprocating motion.

 

Motion modes:

  • Synchronous mode: Work rings 1 and 3 operate simultaneously; upon completion, work rings 2 and 4 perform the motion.

  • Sequential mode: Work rings perform reciprocating motion in sequence (1 → 2 → 3 → 4).

  • Independent mode: Any single work ring can be operated independently as required.

 

Motion parameters:

The reciprocation cycles for each work ring can be independently configured, and the dwell times for forward and backward can be individually adjusted.

 

Rotary motor:

  • Rotary motor power: AC single-phase 220V, 6W x 4 units;

  • When the workpiece is positioned within the work ring, the small motor drives the rotation of the workpiece, with individually adjustable stepless speed control.

 

Intelligent operation interface

  • Equipped with a 7" Weintek MT8071iE HMI.

  • Multilingual interface: Traditional Chinese, English, Vietnamese, Indonesian, Thai.

  • The interface displays real-time operating status and all key settings.

  • Supports manual testing of individual components, sensor status display, and overtime alarm functions.

 

FineCause patented design advantages

  • Pneumatic cylinder-driven design: Automatically drives the work rings, reducing manual operation wear.

  • Detachable lapping pad module: Enables easy daily maintenance and quick replacement.

  • Multi-segment lapping block structure: Ensures uniform slurry distribution and enhances overall processing consistency.

  • Four-point displacement structure: Prevents excessive wear in localized areas of the lapping plate and extends equipment lifespan.

  • The surface roughness measurement report can be provided.

  • Different grades of diamond abrasive and dedicated polishing pads can be selected according to your requirements to achieve multi-stage polishing levels.

  • Test lapping for various workpieces is available — contact us to schedule an appointment!

  • Applicable materials and applications

 

Materials that can be lapped:

Cast iron, aluminum, copper, platinum, gold, silver, high-carbon steel, alloy steel, glass, ceramics, rubber, plastics, quartz, silicon, granite, marble, nylon, carbon, and more.

 

Common workpieces:

SKD11 pad printing steel plates (heat-treated), ceramic components, tungsten carbide parts, crystal materials, watch glass, sapphire, water valves, mobile phone components, oscillators, clutch plates, refrigeration compressor parts, and others.

 

Typical lapping process (Example: SKD11 steel plate)

  • 1️⃣ Rough grinding: Surface irregularities are removed using a surface grinding machine with a grinding wheel.

  • 2️⃣ Precision lapping: The surface is refined using a wet lapping machine with diamond abrasive slurry.

  • 3️⃣ Mirror finishing: A polishing compound and polishing pad are used to achieve high gloss and excellent flatness.

⚠️ Most processing ends at the second stage. However, industries with higher standards—such as contact lens and semiconductor manufacturing—require the third stage of mirror polishing.
