Product Overview
Airway/ventilated sisal buffs are consumable polishing wheels with a structured airflow path, made from sisal cotton. They deliver strong cutting force, durability, and effective cooling during non-plane surface polishing. Used in automatic and semi-automatic polishing machines for medium precision work, hard processing cloth, and fine polishing with mirror finish. Available in outer diameters from 150 mm to 600 mm and inner diameters of iron teeth from 55 mm to 230 mm, or paper cores. Production requires the CRA-800 forming machine, CRA-600 pressing machine, and CRA-700 edge trimming machine.
Key Benefits
- Strong cutting force and durability for consistent polishing performance
- Ventilated structure provides cooling during high-load non-plane polishing
- Suitable for automatic and semi-automatic polishing lines
- Supports medium precision and fine polishing with mirror finish
- Available in outer diameters from 150 mm to 600 mm and iron tooth inner diameters from 55 mm to 230 mm
- Can be mounted on paper cores or iron teeth with round or hexagon holes
Application Scenarios
- A metal finishing shop replacing hand-pressed sisal buffs with machine-made wheels for consistent performance
- A cookware or tableware manufacturer adding ventilated sisal buffs to a semi-automatic polishing line
- A polishing workshop upgrading from manual buffing to automated production with stable output
- A distributor producing their own ventilated sisal buffs to reduce import dependency and freight cost
Who It Is For
- Buffing and polishing wheel manufacturers
- Metal finishing and surface treatment shops
- Cookware, tableware, and sanitary ware producers
- Jewellery and small component polishing workshops
- Distributors of polishing consumables in markets with high import freight
Problems It Solves
- Manual buffing with sisal cloth leads to inconsistent ply density and variable cutting force
- Hand assembly of ventilated wheels cannot maintain repeatable airflow path or edge quality
- Imported sisal buffs have long lead times and high freight costs for frequent reorders
- Lack of standardization in wheel diameter and inner core size limits machine compatibility
Technical Features
- Structured ventilated design allows airflow during polishing for cooling
- Sisal cotton material provides high durability and cutting force
- Outer diameter range from 150 mm to 600 mm supports a wide range of polishing applications
- Inner diameter of iron teeth from 55 mm to 230 mm or paper core mounting option
- Available in no treatment or different hardness treatments for material performance tuning
- Designed for use in automated or semi-automated polishing machines

Materials
- Sisal cotton fabric
- Iron claw centres with round or hexagon holes (55 mm to 230 mm inner diameter)
- Paper cores for mounting
Manufacturing And Process
Step 1
Prepare bias-cut sisal cotton 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 material into the CRA-800 forming machine to create the ventilated wheel body
Step 4
Transfer the formed body to the CRA-600 pressing machine for densification
Step 5
Run the pressed wheel through the CRA-700 edge trimming machine to shape the running face
Step 6
Inspect the finished buff for uniform ply spacing, edge quality, and core alignment
Quality Control
- Hydraulic pressure maintained at 7 MPa during pressing to ensure consistent ply density
- Sample wheels tested before shipment to verify ventilation path and structural integrity
- Free sample testing available using the buyer's own sisal cotton or iron claws
- Installation and operation training provided to ensure correct setup and first-run quality
Customization Options
- Iron claw or paper core mounting options based on the buyer's existing tooling
- Clamp sets provided for specific outer diameter bands within the 150 mm to 600 mm range
- Hardness treatment levels matched to the buyer's polishing requirements
- Machine line packages available with CRA-800, CRA-600, and CRA-700 as a complete production line
Compared With The Alternatives
| CRA-300 Iris Airway Buffs Forming Machine | The CRA-300 covers 100 to 250 mm wheels; use it for small jewellery or bench grinder buffs, not for 150 to 600 mm industrial polishing wheels |
|---|---|
| Manual Sisal Buff Assembly | Hand assembly allows no repeatable ply spacing or airflow path, limits output to under 1000 pieces per day, and increases labor cost |
| Standard Flat Cotton Buffs | Flat cotton buffs lack ventilation and cannot cool effectively during non-plane polishing, leading to heat buildup and material wear |
Use Guide
- Use bias-cut sisal cotton fabric only; straight-cut material will not form properly
- Select the correct iron claw or paper core size to match the inner diameter requirement
- Maintain hydraulic pressure at 7 MPa during pressing to ensure consistent density
- Process formed wheels through pressing and trimming the same shift to prevent ply relaxation

Airway/Ventilated Sisal Buffs FAQ
What outer diameters are available for these ventilated sisal buffs?
From 150 mm to 600 mm (6 inches to 24 inches). The CRA-800 machine covers 200 to 600 mm; for 150 mm wheels, confirm machine compatibility.
Can I use paper cores instead of iron claws?
Yes, paper cores can be nailed into the wheel body. The CRA-800 machine supports both iron claws and paper core mounting.
What hardness treatments are available?
Available in no treatment or different hardness treatments. Specify the required treatment level during order.
What machines are needed to produce these buffs?
The CRA-800 forming machine, CRA-600 pressing machine, and CRA-700 edge trimming machine are required. These are sold separately or as a line.
What is the lead time for delivery?
5 to 15 workdays if in stock, otherwise 15 to 60 workdays depending on model and quantity.
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.
Can you test my own sisal cotton before I buy?
Yes, free sample testing is available. You cover freight and send the specific material you plan to run.
