Working Details

• Phase 1: Requirements & Manoeuvre Catalogue – Established budget ceilings and durability targets, then mapped a sequence of polishing manoeuvres optimised for throughput, edge quality, and long‑term reliability.

• Phase 2: Primary Edge Correction – Addressed the non‑vertical edges left by slab cutting with five sequential polishers of graduated grit, aligned perpendicular to the slab face to achieve an initial mirror finish.

• Phase 3: Final Shine & Safety – Integrated six additional polishers arranged as two tri‑motor pairs acting 90° apart along the edge. Each half‑ton waterproof motor applied ~70 N m² perpendicular load while executing a radial path via a four‑bar linkage sized using an RDF cycloidal‑didial polynomial for the required oscillatory effect.

• Phase 4: Kinematic Design – Derived linkage lengths and cam profiles to maintain synchronous motion and uniform contact pressure across variable slab geometries, using SolidWorks motion studies and Fusion 360 validation loops.

• Phase 5: Fabrication & Assembly – Machined structural and kinematic components on VMCs, applied GD&T for interchangeability, and integrated pneumatic jacks and proximity sensors for automated in‑feed control. Field assembly by technicians resulted in a fully operational system at roughly one‑tenth the cost of a comparable Chinese import.

Post‑commission tests confirmed edge accuracy, surface roughness, and cycle time met or exceeded benchmarks, validating the controlled‑loop architecture and synchronous drive strategy.
