High-Precision Robotic Deburring And Polishing Machine for Three
Way Pipe Connector
Product Overview
The two parts in the photograph tell the complete story. On the
left: a tri-arm aluminium die cast pipe connector fresh from the
casting die with parting-line flash, rough casting skin, and
oxidised tube bore. On the right: the same casting after processing
with the LR-DP-HP-PC machine - clean parting lines, flat arm faces,
mirror-finished flanges, and smooth tube bore. This represents true
high-precision deburring and polishing that prepares parts for
chrome or PVD finishing.
Three-Way Aluminium Pipe Connector Applications
This structural and aesthetic fitting is used in premium furniture,
retail and exhibition displays, architectural hardware, and
industrial equipment. The connector must meet both dimensional
precision and mirror-finish aesthetic requirements simultaneously.
- Premium furniture: Central column-base on dining tables, office desks and display
pedestals
- Retail and exhibition display: Structural node of display systems and shop fittings
- Architectural hardware: Stair baluster bases, balcony handrail supports, shower enclosure
fittings
- Industrial equipment: Pipe-support structures, modular machine frames, conveyor-rail
intersections
Key Technical Features
Compound-Curve Parting-Line Flash Removal
Phase D1 uses a curve-following edge tool programmed from the
connector's CAD profile that traces exact parting-line geometry
while maintaining consistent contact force through all geometry
changes. The surrounding arm face and boss material are never
contacted by the flash-removal tool.
Boss-Face Protection
Phase D3 and Phase P2 include boss-face flatness protection
protocols that ensure flat faces for clamping or sealing
applications. Tools stop at precise distances from the face plane,
preserving flatness while achieving required surface refinement.
Frequently Asked Questions
1. Can the machine reach parting-line geometry through fillet
transitions?
Yes - Phase D1 specifically addresses this challenge. The tool path
follows the parting line through straight arm sections, curved
fillet transitions, and boss circumference with continuous approach
angle changes. The fillet material and boss surface are protected
by a path clearance zone.
2. How does the machine ensure consistent sheen levels across all
three arms?
The LR-DP-HP-PC uses C-axis arm indexing where the same programme
runs on each arm in sequence with identical contact force, dwell
time, and tool state. After Phase P3, the GU sensor measures each
arm separately and correction passes are applied as needed to
maintain arm-to-arm GU deviation within specified tolerances.
3. Will the deburring tool contact the centre bore wall?
No. The bore ID is hard path-excluded with specified clearance. The
part is registered on the bore OD shoulder, and all paths reference
the bore axis without entering the bore. The bore-entry edge is
conditioned by an axial-approach tool that works from outside the
bore without contacting the bore wall.
