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

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

 

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

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.

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.

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:

  • 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.

 

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.
