The Short Version
Jewellery and small metal parts polishing requires consistent, fine finish wheels with tight diameter control. The CRA-300 iris machine forms airway buffs from 100 mm to 250 mm, covering the standard size range for rings, findings and bench polishing. A dedicated edge fuzzing napping machine raises the wheel surface to hold polishing compound. Small wheels for angle grinders are made on the 200A mini cloth sisal forming machine.
Where It Goes Wrong
- Hand forming small wheels leads to inconsistent ply spacing and uneven finish on delicate parts
- Manual edge trimming on small buffs leaves frayed fibres that scratch jewellery surfaces
- Lack of dedicated small wheel machines means using oversized equipment with poor control
- Compound does not adhere well on flat wheel faces without surface texture
- Small batch production requires frequent machine setup changes with no standard tooling
What Buyers Need
- A forming machine that holds precise 100 to 250 mm outer diameter across shifts
- Tooling that matches existing 2 inch and 2.5 inch iron claws and plates
- An edge fuzzing napping machine to raise the wheel face for compound retention
- A compact forming machine for 200 mm and smaller wheels used in angle grinders
- English interface and operation manual to match the control panel
Typical Situations
- A jewellery polishing workshop automating the production of 150 mm mirror finish wheels for ring polishing
- A small parts manufacturer adding 100 mm buffs for finding and tool polishing using the CRA-300
- A workshop producing 200 mm wheels for angle grinders with the 200A mini forming machine
- A bench polishing line upgrading from hand folding to a fully automated forming and fuzzing process
How The Work Runs
Step 1
Bias fabric cutting and rolling on the CRA-500 for consistent feed to the CRA-300
Step 2
Forming on the CRA-300 iris machine for 100 to 250 mm outer diameter wheels
Step 3
Edge fuzzing napping on a dedicated machine to raise the surface for compound retention
Step 4
Pressing on the CRA-600 for consistent density and shape
Step 5
Trimming on the CRA-700 for clean edges, or manual trimming if batch size is low
