Rotary Polishing Machine
& Polishing Line

Polishing is the classic slow, dusty, hard-to-staff job: pressure comes from the hand, consistency depends on the person, and both rework and consumable cost run out of control. We broke the process into stages — skin pass, rough, fine, satin — and built them into machines with multi-station belt and flap-wheel heads. One unit extends to several linked machines, then to a complete line with robots and conveyors. Dust collection moved from a water-curtain booth to our own dry pulse-jet cabinet: no water, no waste water.

WHY AUTOMATED POLISHING

From “feel”
to parameters

Hand polishing quality depends on the person: change shift, change operator, lose energy, and pressure and dwell time change with it — rework rate and consumable consumption swing with them. The point of automating is not speed. It is that force, time and path are identical every cycle, so craft becomes parameters and a new operator can hold the finish.

  • Staged process — skin pass → rough → fine → satin, with dedicated stations for inner wall, inner base, outer wall and outer base
  • Multi-station build — outer polisher / belt machine / inner polisher / satin machine combined to suit the part; two stations is the basic unit
  • Servo positioning — position and dwell time are stored as recipes — a new size doesn't start from zero
  • Pulse-jet dust cabinet — our own dry system: no water, no waste water, dust collected in a drawer, automatic cleaning
  • Grows into a line — single unit → linked machines → full line with robots and conveyors, manual or automatic loading

DELIVERY & ACCEPTANCE

Delivery and acceptance

01

Scope confirmed first

Part dimensions, target output, existing process and site conditions are agreed before the machine is configured.

02

Pre-acceptance at our plant

You test with your own parts and approve cycle time and finished quality before shipment.

03

Installation on site

We install, tune the parameters, and run it until it produces steadily.

04

Training and support

Operator and maintenance training; long-term technical support, on site when needed.

FAQ

What customers ask us most

These are the questions that actually come up on calls and on site. Answers describe how we really work, including what we can't do.

We have four people polishing. How many does a machine replace?

Before counting heads, find out what actually jams this step. If hiring is the problem — you can't recruit or retain — the value of the machine is removing “person” as a variable. If rework is the problem, the fix is process, not headcount. Typically one line runs with one operator inspecting and one handling load, but the real number depends on how many stations and which parts.

Will the finish be worse than our senior polisher?

Short term yes, long term no. A good polisher does have the touch — but only those few people, and it changes when you change shift or they get tired. A machine won't match that person's best piece, but every piece sits on the same line. If you want to compare, send samples and we'll put roughness and gloss figures on the table instead of adjectives.

Dust is heavy. How do we pass an environmental inspection?

We build enclosed machines with internal filtration, the wash water is recirculated, and dust is collected in a box for disposal. But robot loading and dry polishing will still produce dust — that's honest. Dust is captured at the station, air volume sized to the number of stations, outlet connected to your existing extraction main. Inspectors check workplace concentration and the discharge point; we supply the duct drawing and airflow figures you submit. Wet polishing has less dust, but needs slurry circulation and drying, plus floor and water treatment.

We already own a polishing machine. Is it worth replacing?

First look at where it hurts: can't reach the grade, consumables eat too much, changeover too slow, or people won't stay. The first three can often be fixed — different belt spec, constant-pressure control, new fixtures — without a new machine. Replace only when cycle time and consistency are both stuck. Send me your current parameters and reject rate and I'll tell you if it's worth it.

Roughly what does a set cost?

Driven by station count, which parts you polish, and whether you need robots and extraction. Two quotes for “the same class” of machine can differ by 2x — the money is in stations and automation level, not the brand. Give me part dimensions, required surface and shift output, and I'll quote a range against a proposal.

What do consumables cost per year?

Belts, cloth wheels, sisal wheels and polishing compound — the big part of long-term cost, well above electricity. How much depends on material and how much stock you remove. We build that number into the selection exercise; comparing machine price alone is misleading.

Can we trial-polish our own parts?

That's the right way. Send parts, or let us visit and watch how you polish today. Afterwards you get a roughness and gloss comparison plus a sample you can hold and touch — photos and video don't settle polishing.

How hard is it to run? Do we need to hire a specialist?

Automating is turning hand skill into parameters. Tuning them takes some experience, but far less than finding a polisher who can hold a grade. Recipes are stored; recall one for a new part. We train your people.
