Product Description
Automated Two Stations Of CNC Polishing Machine For Hardware Door Handle
Automated two-station CNC polishing machine for door handles: load, buff, unload — continuous cycle for lever handles & knobs. Up to 1,200 pcs/shift with 1 operator.
Purpose-built for high-volume door hardware
Lever handles, knobs and pulls loaded by conveyor, buffed at two dedicated stations, unloaded automatically. One operator keeps the cell running — output that used to need a polishing line.
- 1,200 pcs/shift typical output on lever handles (2-station continuous cycle)
- Automatic loading & unloading — operator only tops up the magazine
- Ra 0.05 µm mirror finish on brass / zinc alloy / stainless handles
- 6-8× labor saving vs manual buffing line (1 operator vs 6-8 polishers)
The Challenge — Door Handles Are High-Volume, Low-Margin, Finish-Sensitive
An automated two-station CNC cell turns door handle polishing from a labor bottleneck into a continuous, predictable process.
Why Automated Two Stations?
Two stations mean an optimal division of labor: the surface finishing process for door handles essentially consists of two steps—coarse polishing (base prep) and fine polishing (finishing). A two-station setup completes both in a single pass, requiring lower investment and offering a faster return on investment (ROI) compared to four-station systems.
Automated loading and unloading is the core: Door handles have regular shapes and allow for batch feeding; they are ideal for tray or vibratory feeding combined with automatic unloading, truly enabling "continuous machine operation with minimal human oversight."
Cycle times suited for mass production: With a cycle time of 8-20 seconds per piece and alternating operation between the two stations, equipment utilization is high, driving the cost per unit down to just 1/5-1/8 of manual processing costs.
Rapid changeover for multiple specifications: Dedicated fixtures and programs exist for levers, knobs, and pull handles; changeover takes less than 10 minutes, allowing for mixed-model production without stopping the line.
Compatibility across the door handle product family: A single production line can handle the three mainstream types—doorknobs, lever handles, and pull handles.
Suitable Workpieces and Application Scenarios
- Lever handles (Mainstream in Europe; includes mortise/tubular base types)
- Doorknobs (Mainstream in the US)
- Pull handles (Commercial pulls, long bar handles)
- Escutcheons / Backplates (Keyhole covers, mounting plates)
- Dummy handles / Flush pulls (Decorative handles, recessed pulls)
Frequently Asked Questions
What makes this "automated" — do we still need operators?
The machine loads, polishes and unloads automatically. One operator tops up the feeder and removes finished bins — typically one person runs two cells.
Can it do both lever handles and round knobs?
Yes. Each shape has a dedicated fixture and stored program; changeover takes under 10 minutes, so mixed lever/knob/pull production runs without stopping.
Our handles go to electroplating after polishing — will the surface be consistent enough?
Yes. Force-controlled polishing keeps material removal uniform, so the pre-plate surface is consistent batch to batch — reducing plating defects and color mismatch.
What about cast handles with gate marks?
Add the deburring option at Station 1 — gates and mold lines are removed in the same pass before the finishing buff.
Can you give a cycle time for our specific handle?
Send the part drawing and target finish — we return cycle time, consumables plan and payback within 48 hours.
What if our order volume changes seasonally?
The cell scales with demand: run one shift, two shifts, or add a second machine. Labor cost follows output automatically — no idle payroll.
