Product Overview
The CRA-360 forms corrugated or weave polishing buffs, also known as airflow buffs, from sisal or cloth. It produces wheels with outer diameters in 20, 30, 32, 36, and 44 mm options. The machine automates the forming step using a wave forming knife system, cloth rolling device, and pneumatic or hydraulic control. One operator runs the full cycle. It replaces manual folding and shaping, reducing labor and improving consistency. The machine is part of a larger production line that includes bias fabric preparation, pressing, and edge trimming.
Key Benefits
- One operator replaces multiple workers on manual forming of corrugated buffs
- Automated forming ensures consistent wave pattern and ply alignment
- Supports 20 mm to 44 mm outer diameter wheels with clamp set changes
- Runs untreated cotton, treated cotton, and sisal cloth on the same machine
- Pneumatic or hydraulic control systems available for different pressure needs
- Clamp set change takes 20 minutes, allowing quick diameter switching
Application Scenarios
- A polishing wheel factory replacing manual corrugated buff forming with automation
- A distributor adding high-end weave buffs to their product line without hiring more staff
- A workshop producing small-diameter buffs for jewellery or precision metal finishing
- A plant that already uses a CRA-500 bias cutter and needs the forming step next
Who It Is For
- Buffing and polishing wheel manufacturers
- Abrasive product makers expanding into corrugated or airflow buff lines
- Metal finishing shops producing custom buffs in small to medium batches
- Distributors in regions where imported weave buffs have high freight and lead time
Problems It Solves
- Manual corrugated buff forming leads to inconsistent wave depth and ply spacing
- Hand shaping limits output and increases labor cost per wheel
- Changing wheel size by hand requires retraining and new tools
- Inconsistent forming causes uneven wear and poor polishing results on final parts
Technical Features
- Wave forming knife system creates consistent corrugated structure
- Automatic cloth/sisal rolling device feeds material continuously
- Pneumatic or hydraulic control system drives the forming cycle
- Clamp system holds material during forming and allows ring placement
- Electrical control box manages timing and pressure sequences
- Connecting device links the rolling, forming, and clamping stages

Manufacturing And Process
Step 1
Load the fabric or sisal roll onto the winding rack
Step 2
Close the clamps and start the forming cycle via the control panel
Step 3
The wave forming knife creates the corrugated structure during roll forming
Step 4
The machine presses the material into shape and holds it with clamps
Step 5
Place the iron clinch ring onto the formed body
Step 6
Re-close the clamps and press the ring into place
Step 7
Unload the finished corrugated buff for pressing on a CRA-600 or similar
Quality Control

- Hydraulic or pneumatic pressure maintained at 7 to 9 MPa for uniform density
- Clamp set tolerance allows ±100 mm in outer diameter, verified before use
- Free sample testing available on buyer’s own fabric or sisal
- Installation and operation training provided to ensure correct setup
Customization Options
- Voltage and phase configured for destination country
- Clamp sets supplied for 20, 30, 32, 36, and 44 mm diameter bands

Compared With The Alternatives
| CRA-800 Bias Airway Buffs Forming Machine | The CRA-800 forms ventilated airway wheels from 200 to 600 mm; the CRA-360 makes small corrugated buffs from 20 to 44 mm |
|---|---|
| CRA-300 Airway Buffs Forming Iris Machine | The CRA-300 forms small iris-type airway wheels; the CRA-360 forms corrugated weave buffs with a different structure |
| Manual corrugated buff forming | Hand forming requires multiple workers and lacks consistency; the CRA-360 automates the process with one operator |
Use Guide
- Ensure fabric or sisal is bias-cut before loading; straight-cut material will not form correctly
- Change clamp sets only when switching between diameter bands; each change takes 20 minutes
- Maintain air pressure between 7 and 9 MPa for consistent wave formation and ring seating
- Do not skip the iron clinch ring step; it is required for structural integrity
- Contact us on WhatsApp for the English operation video if the operator is new to corrugated forming
CRA-360 Airflow Buffs/Corrugated Polishing Buffs Making Machine FAQ
What diameter of corrugated buffs can this machine make?
From 20 mm to 44 mm outer diameter. The machine supports 20, 30, 32, 36, and 44 mm options.
How many people are needed to run it?
One operator. The machine handles winding, forming, clamping, and ring pressing automatically.
What is the daily output?
Not specified in the source. Output depends on diameter, ply count, and material.
Do I need other machines to make a finished wheel?
Yes. The CRA-360 forms the body. After that, pressing and edge trimming are required. We supply CRA-600 and CRA-700 for those steps.
What is the lead time?
5 to 15 workdays if 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.
Can you test my own fabric before I buy?
Yes, free sample testing is available. You cover freight and send the specific material you plan to run.
