Detailed Specifications & Features
Robotic Aluminum Polishing Machine For Smart Door Lock
Purpose-built robotic polishing cell for zinc alloy and aluminum die-cast door lock face panels, back covers, and handle bodies. Delivers consistent Ra ≤ 0.2 µm pre-plating finish across complex contoured surfaces — fully automated, zero skilled-operator dependency.
Product Overview
Smart door lock housings are among the most demanding surface finishing challenges in consumer hardware manufacturing. The die-cast zinc alloy or aluminum face panel must clear parting-line flash, gate remnants, and ejector-pin marks — then achieve a mirror-grade or satin finish that survives electroplating, PVD coating, or powder coating without defects.
Manual polishing of these complex, multi-cavity, multi-feature parts is slow, inconsistent, and impossible to scale without a large skilled workforce. The LRMC-DL Series Robotic Polishing Machine solves this with 6-axis force-controlled automation, automatically adapting contact pressure and tool path to the irregular geometry of lock housings — delivering plating-ready surfaces at 3-5* manual throughput.
Key Features
Force-Controlled Polishing — Adapts to Every Curve and Recess
Smart door lock housings are not flat. The face panel combines flat fields, recessed keypad windows, raised boss rings around the cylinder hole, and radiused edges. A rigid-tooling polisher gouges the recesses and skips the bosses.
The LRMC active force control module maintains constant contact force (±0.5 N) regardless of surface angle or height transition, ensuring:
- Uniform material removal across flat zones and contoured surfaces
- No over-polishing at edges or raised bosses
- No under-polishing in shallow recesses and near window cutouts
- Force range: 5-80 N, fully programmable per zone
Dual-Face Program — Front Panel + Back Cover in One Cell
The cell can store separate polishing recipes for the face panel and the back cover/battery compartment housing. A simple fixture swap (< 3 min) switches between the two programs — keeping both halves of the door lock assembly on the same production line.
- Recipe storage: 500+ part programs
- Changeover time (new fixture, same part family): < 5 minutes
- Automatic part recognition via RFID or vision trigger (optional)
Consistent Pre-Plating Surface Quality
Electroplating and PVD coating are unforgiving. Any scratch, pit, or surface waviness left by polishing will telegraph through the plating layer and cause field returns.
The LRMC-DL delivers:
- Surface roughness: Ra ≤ 0.2 µm (pre-plate target for bright chrome / satin nickel / black PVD)
- Waviness Wt ≤ 0.8 µm
- Part-to-part Ra variation: ≤ ±5%
- Zero cross-contamination between abrasive stages (enclosed guard + dust extraction)
ROI Reference (Smart Door Lock Scenario)
Assumptions:
- 2 shifts/day, 250 days/year
- Replace 6 manual polishers @ USD 16/hr fully loaded
- Monthly abrasive spend: USD 2,500 → 30% saving = USD 750/month
- Current plating reject rate: 10% → reduced to 1% on 10,000 pcs/month @ USD 1.20 rework cost
Annual Saving Breakdown:
| Item | Annual Saving (USD) |
|---|---|
| Labor (6 operators * 2 shifts) | ~230,400 |
| Abrasive consumables | ~9,000 |
| Plating rework reduction | ~10,800 |
| Total | ~250,200 |

Frequently Asked Questions
Q: Can the machine handle both zinc alloy and aluminum die-cast door lock housings?
A: Yes. The abrasive selection and force parameters are independently programmable per material. Zinc alloy (Zamak, ZA-8) and aluminum (ADC12, A380) housings run on separate recipes stored in the same controller.
Q: Our face panel has a large round boss around the cylinder hole. Can the robot polish inside the radius without gouging the edge?
A: Yes. The active force control module combined with a conical or tapered polishing wheel is specifically configured for this geometry. The robot path is programmed to follow the boss radius with constant normal-force contact.
Q: What surface finish (Ra) is achievable before electroplating?
A: Typically Ra ≤ 0.2 µm for bright chrome or satin nickel pre-plate requirements. For PVD or decorative black finish, Ra ≤ 0.1 µm is achievable with the 6-stage abrasive sequence.
Q: How long does it take to program the machine for a new door lock housing model?
A: With a DXF or STEP file, a new part program is generated in under 30 minutes. For repeat part families with minor dimensional changes, adapting an existing recipe takes under 10 minutes.
