Product Overview
Airway/ventilated cotton buffs are used in automatic and semi-automatic polishing machines for medium precision polishing, hard processing cloth polishing, and mirror finish applications. They are made from pure cotton or flannel fabric, with outer diameters from 150 mm to 600 mm and inner diameters of iron teeth from 55 mm to 230 mm, or paper cores. The fabric can be naturally soft or treated in grey, pink, yellow, orange, or blue for different hardness levels. These buffs are produced using the CRA-800 forming machine, CRA-600 pressing machine, and CRA-700 edge trimming machine in sequence.
Key Benefits
- Used in automatic and semi-automatic polishing lines for consistent finish quality
- Outer diameter range from 150 mm to 600 mm covers most industrial polishing needs
- Inner diameter supports iron claws from 55 mm to 230 mm or paper cores for custom mounting
- Fabric options include natural cotton, flannel, and treated colours for varying hardness
- Hardness levels match different polishing stages from medium precision to mirror finish
- Machine line integration ensures repeatable shape and ply spacing across production runs
Application Scenarios
- A polishing line upgrading from hand-made buffs to automated production with consistent wheel shape
- A manufacturer adding ventilated cotton buffs to their product range for mirror finish applications
- A workshop producing buffs in-house to reduce reliance on imported consumables
- A metal finishing shop needing medium precision polishing with low cost, high durability buffs
Who It Is For
- Buffing and polishing wheel manufacturers
- Metal finishing shops using automatic or semi-automatic polishing machines
- Cookware and tableware producers requiring mirror finish on stainless steel
- Sanitary ware polishing lines needing durable, ventilated buffs for hard processing
Problems It Solves
- Hand-made cotton buffs vary in ply spacing and shape, leading to inconsistent polishing results
- Manual production limits output and increases labour cost per unit
- Imported cotton buffs carry high freight and long lead times for reorders
- Changing hardness or diameter by hand requires retraining rather than tooling adjustment
Technical Features
- Ventilated structure allows heat and debris to escape during high-speed polishing
- Cotton or flannel fabric can be used in natural or treated forms for different hardness
- Iron claw or paper core mounting supports inner diameters from 55 mm to 230 mm
- Treated fabric in grey, pink, yellow, orange, blue provides adjustable hardness
- Designed for use with CRA-800 forming, CRA-600 pressing, and CRA-700 trimming machines
- Outer diameter range from 150 mm to 600 mm covers standard industrial wheel sizes

Manufacturing And Process
Step 1
Prepare bias-cut cotton or flannel fabric on a CRA-500 bias cutting and rolling machine
Step 2
Load the fabric roll and select the iron claw or paper core for the wheel centre
Step 3
Feed the fabric into the CRA-800 forming machine to fold and index the material into a ventilated body
Step 4
Transfer the formed body to the CRA-600 pressing machine to compress the ply stack
Step 5
Move the pressed wheel to the CRA-700 trimming machine to cut the edge and define the running face
Step 6
Inspect the finished buff for shape, ply density, and edge quality before packaging
Quality Control
- Hydraulic pressure maintained at 7 MPa on the CRA-600 press to ensure consistent ply density
- Sample buffs tested before shipment to verify shape, hardness, and edge finish
- Free sample testing available using the buyer's own fabric or treated cloth
- Installation and operation training provided to ensure correct setup and first-run success
Customization Options
- Iron claw tooling supplied for the inner diameter range the buyer uses
- Clamp sets and forming dies matched to the target outer diameter bands
- Fabric treatment colour and hardness level specified by the buyer
- Machine line can be quoted with CRA-500, CRA-800, CRA-600, and CRA-700 as a complete system
Compared With The Alternatives
| CRA-300 Airway Buffs Forming Iris Machine | The CRA-300 covers 100 to 250 mm wheels; use it for small bench tools, not for 150 to 600 mm industrial polishing wheels |
|---|---|
| CRA-360 Airflow Corrugated Buffs Making Machine | The CRA-360 forms corrugated buffs with a different structure, not ventilated cotton buffs |
| Manual cotton buff assembly | Hand assembly is slower, less repeatable, and cannot support daily output above 1000 units per shift |
Use Guide
- Ensure fabric is cut on the bias before forming; straight-cut material will not fold evenly
- Change iron claw or paper core size to match the target inner diameter; tooling change is not required daily
- Maintain consistent hydraulic pressure on the CRA-600 press to avoid loose or dense ply stacking
- Process formed wheels through pressing and trimming the same shift to prevent ply relaxation

Airway/Ventilated Cotton Buffs FAQ
What outer diameters can these cotton buffs make?
From 150 mm to 600 mm. For wheels below 150 mm, use the CRA-300 iris machine.
Can I use paper cores instead of iron claws?
Yes, paper cores can be used for mounting. The inner diameter range is 55 mm to 230 mm.
What fabric types are available?
Pure cotton and flannel. Fabric can be natural or treated in grey, pink, yellow, orange, or blue for different hardness levels.
What machines are needed to produce these buffs?
The CRA-800 forming machine, CRA-600 pressing machine, and CRA-700 trimming machine are required in sequence.
What is the lead time for production?
5 to 15 workdays if the machine is in stock, otherwise 15 to 60 workdays depending on quantity and model.
What are the payment terms?
Orders up to 10000 USD are 100% in advance. Above 10000 USD, it is 30% T/T deposit with the balance before shipment.
