Flexible CNC Polishing Machine For Handle Hardware
Flexible CNC Polishing Machine For Handle Hardware
Flexible by Design — Changeover in Minutes, Not Days
Handle hardware is a family business: dozens of models, small batches, constant changeovers. A machine that needs half a day to re-setup is a machine that loses money.
- Recipe-based programming stores every model — lever, T-bar pull, cup pull, knob, escutcheon — called up by part number.
- Quick-change fixtures and zero-point clamping swap tooling in minutes; family-of-parts fixtures cover multiple lengths and profiles.
- The same cell switches surface finish by program, not by hardware change: mirror today, satin this afternoon, pre-plating base tomorrow morning.
Precision & Consistency — One Finish, Every Handle
- Force-controlled polishing holds contact pressure constant along bars, ends and curves — identical surface on every handle in the batch, and the next batch, and the one after.
- ±0.05 mm repeatability and locked recipes deliver Ra-consistent finish, part after part.
- No orange peel, no waviness, no burn marks on thin handle cross-sections.
Multi-Material Ready — Brass, Zinc, Aluminum, Steel
Handle hardware is made from everything — and a polisher that handles only one alloy only serves part of your range.
- Brass H59/H62 and lead-free brass: force-controlled, burn-free mirror base.
- Die-cast zinc: light pressure, fast passes — no smearing, no over-polish on the soft alloy.
- Aluminum: pre-anodizing base prep, scratch-free.
- Stainless steel 304/316: satin and mirror paths for the growing stainless segment.
- Material-specific pressure profiles are stored per model — switch material with the recipe, not a manual re-tune.
Surface Versatility — Mirror, Satin, Pre-Plating
Handles sell on surface: polished brass, satin nickel, brushed chrome, PVD-ready base. The finish is part of the product spec.
- Mirror finishing to Ra μm for polished brass and chrome-ready bases.
- Satin and brushed paths for brushed nickel, satin chrome and architectural finishes.
- Pre-plating base prep that plating lines accept without re-polish.
- Finish is a program parameter — the same physical cell delivers any surface in your catalog.
Small-Batch Economics — Profit on Runs of 100
- Changeover in minutes means a 100-piece run is economical — no minimum batch size to justify setup.
- Family fixtures batch several handle models in one cycle: load mixed models, polish all, unload.
- WIP shrinks: no need to accumulate large batches before a changeover makes sense.
Automation & Integration — Tray In, Finished Out
- Tray or conveyor feed interfaces with your production line; PLC handshake and MES connectivity are standard.
- Integrated dust and compound extraction keeps the cell clean and compliant.
- Cell guarding to ISO 10218, ready for plant audits.
Load the tray of handles. Collect the finished batch.
Traceability — Batch Records for Every Model
- Per-piece logging records force, cycle time and result status, tagged by barcode or tray position.
- Batch-level records per model — a finish complaint traces to its parameters in minutes.
- MES export builds audit-ready quality files for OEM and export compliance.
Frequently Asked Questions
How fast is the changeover between handle models?
Within the same fixture family, changeover is a recipe call — typically minutes, including tooling swap via quick-change fixtures. Between families, zero-point clamping keeps re-setup under minutes. Final numbers come from a changeover demonstration on your parts.
Can the same cell really handle brass, zinc, aluminum and stainless steel?
Yes. Material-specific pressure profiles are stored per model: lead-free and die-cast zinc run light and slow to avoid over-polish, brass and steel run standard, aluminum gets pre-anodizing prep paths. Switching material is a recipe parameter, not a machine re-tune.
Can it switch between mirror and satin finish without changing hardware?
Yes — surface finish is a program parameter. Mirror, satin and pre-plating base paths use the same tooling with different speeds, pressures and media; the cell switches by program. Media change for extreme cases uses the quick-change spindle.
Is a 100-piece batch economical on this machine?
Yes. With changeover in minutes, the setup cost per run collapses — there's no minimum batch size to justify the machine. Family fixtures even batch several models in one cycle: load mixed handles, polish all, unload.
What Ra can you guarantee?
Mirror finish target is Ra μm on brass and steel, validated on a sample piece before you commit. Satin and brushed paths are spec'd against your reference sample.
What is the payback for replacing 2-3 polishers?
Typically 12-18 months, driven by scarce-polisher labor cost, reduced changeover downtime and lower re-polish rates. We model it with your actual labor cost, batch mix and shift plan.
