Fully Automatic Robotic Deburring and Polishing Machine for Aluminum Wheel Hub
Aluminum wheel hubs present a unique finishing challenge: they are the largest, most geometrically complex aluminum castings in automotive production, yet their as-cast defects are highly visible to end customers. Any remnant gate, spoke flash line, or burred PCD hole that reaches the paint line becomes a visible defect after painting, leading to warranty claims.
Wheel hubs require finishing across three distinct zones:
The cosmetic face - spokes and rim barrel, visible from all angles under various lighting conditions
The functional face - bolt holes (PCD), centre bore, lug-nut seats, and bead seats that govern mounting, torque, and tire sealing
The invisible back - spoke backs, window undersides, and vent openings where flash lines can cause balance weight adhesion failure
The LR-DP-WH is a fully automatic robotic deburring and polishing machine specifically designed for these three-zone requirements. It removes gates and risers, trims spoke and window flash, edge-breaks every PCD hole and centre bore, and conditions surfaces for painting - or polishes to mirror finish for premium applications. Operating on centre-bore-registered fixtures that protect runout-critical dimensions, this system integrates with casting and paint lines to finish wheels unattended at line rate with comprehensive quality control records.
Proprietary Selling Points
1. Centre-Bore Datum Registration - Runout-Critical Geometry Protection
The wheel's centre bore serves as the mounting datum for the hub, balancing machine, and wheel-bore centring fixtures. Any tool contact with this critical surface can compromise hub-centricity.
Each wheel registers on a centre-bore pilot fixture matched to the machined bore
All deburring and polishing paths reference the pilot axis, ensuring consistent spoke pattern, PCD bolt circle, and rim barrel finishing
The bore surface and pilot bore face are hard path-excluded with [TBC] mm clearance
Bore entry edge deburring uses separate axial tools that approach from outside, never contacting the bore wall
Bead seats and lug-nut seats receive identical protection through path exclusion zones
Bore pilot precision: [TBC] mm concentricity; bore exclusion clearance: [TBC] mm; lug-seat exclusion: [TBC] mm from seat cone
Phase P1 conditioning to paint Ra window; peel eliminated at source
Mirror segment
Manual mirror polishing not scalable
Phase P2 flannel sequence; Ra ≤ [TBC] µm at line rate
Line rate
Benches bottleneck between casting and paint
Twin-station index + conveyor link; [TBC] wheels/h
QC documentation
Visual spot check
Dual gates + per-wheel record; traceable by DMC
Frequently Asked Questions
1. Our bolt holes and centre bore are machined to tight tolerance. How does the deburr stage avoid touching them?
Through datum registration and hard path exclusion. Every wheel registers on a centre-bore pilot matched to the machined bore - all paths reference the bore axis. The bore surface and pilot bore face are hard path-excluded with [TBC] mm clearance. Bolt-hole deburring uses axial entry tools that edge-break hole entries and exits while maintaining [TBC] mm clearance from lug-seat cones. Bead seats and lug-nut seats receive identical protection. Runout-critical geometry remains untouched by deburring or polishing tools - confirmed through your wheel drawings before programming.
2. We paint our wheels high-gloss and fight orange-peel. Is that a paint problem or a polishing problem?
Typically, it's a substrate problem first. Cast skin roughness telegraphs through high-gloss paint as orange-peel - paint booths cannot compensate for substrate Ra variation. The LR-DP-WH's Phase P1 conditioning pass reduces cosmetic faces to the Ra window your paint specification requires before wheels enter the booth. Orange-peel from substrate variation is eliminated at source. Send us painted wheels with peel issues, and we'll measure substrate Ra contribution during trials.
3. How does the machine reach the back of the wheel - the riser zone and back-window flash that always cause balance-weight problems?
The back receives dedicated programming as a full phase, not just secondary operation. Phase R (riser/gate removal) processes back pads with cut-off discs or carbide burrs to [TBC] mm flush limits. Phase W reaches into back-window and vent openings with specialized tools for full-perimeter edge deburring. The C-axis fixture presents wheels back-first to tools, providing direct access to all back zones at each spoke index position.
4. We run 5-spoke, 6-spoke and 8-spoke wheels in the same month. How is changeover handled?
Wheel changeover involves: fixture pilot change (bore diameter) + recipe selection (spoke count, PCD pitch, programme bay geometry). Programming stores per wheel family as single-bay paths repeated at spoke pitch intervals. Changing from 5-spoke to 6-spoke calls the 6-spoke recipe with its specific bay programme and pitch. Target changeover: [TBC] minutes. Pilot and recipe libraries cover your complete wheel family range.
