Product Overview
The CRA-600 presses buffing and polishing wheels after forming on the CRA-800 or CRA-300. It applies hydraulic pressure up to 45 tons to compact the wheel body, ensuring consistent density and improved endurance. The machine handles cotton, sisal, airway buffs, nylon, and similar materials. It is the pressing step in a four-machine line: bias cutting on the CRA-500, forming on the CRA-800 or CRA-300, pressing here, and edge trimming on the CRA-700.
Key Benefits
- One operator runs the pressing step, replacing manual or semi-automatic pressing methods
- Maximum hydraulic pressure of 45 tons ensures consistent density across all wheel types
- Handles cotton, sisal, airway buffs, nylon, and similar materials without retooling
- Adjustable pressing height for different wheel thicknesses and moulds
- Moulds can be changed quickly to switch between wheel types or sizes
- Control interface and machine language are in English for clear operation
Application Scenarios
- A buffing wheel factory replacing hand pressing with automated, repeatable pressure
- A workshop adding a new wheel type like nylon or airway buffs and needing a reliable press
- A manufacturer scaling up production from 1000 to 5000 wheels per day and needing consistent pressing
- A company integrating the CRA-600 into a full line with CRA-500, CRA-800, and CRA-700
Who It Is For
- Buffing and polishing wheel manufacturers
- Metal finishing shops producing their own wheels in volume
- Cookware and sanitary ware polishing lines requiring durable wheels
- Jewellery polishing workshops needing consistent wheel density
Problems It Solves
- Manual pressing leads to inconsistent density, causing uneven wear and short wheel life
- Hand or low-pressure pressing cannot achieve the 45 ton density needed for high-end wheels
- Changing wheel types requires different pressing tools; the CRA-600 allows quick mould swaps
- Lack of pressure control causes batch-to-batch variation in wheel hardness and performance
Technical Features
- Hydraulic system with maximum pressure of 45 tons for wheel compaction
- Adjustable pressing height to match mould and wheel thickness
- Upper and lower moulds with quick-change mechanism for different wheel types
- Control panel with pressure gauge and on/off switch for monitoring
- Oil reservoir with fill port; oil must be added after shipping due to loss during transit
- Sturdy steel frame with anti-vibration mounting for stable operation

Manufacturing And Process
Step 1
Load the formed wheel body onto the lower mould
Step 2
Select and install the correct upper and lower moulds for the target wheel type
Step 3
Adjust the pressing height to match the wheel thickness
Step 4
Start the hydraulic press; the system applies pressure up to 45 tons
Step 5
Hold pressure for the set cycle time, then release and remove the pressed wheel
Step 6
Transfer the pressed wheel to the CRA-700 edge trimming machine for finishing
Quality Control
- Hydraulic pressure held at 45 tons during pressing to ensure consistent density
- Sample wheels tested before shipment to verify compaction and shape
- Free sample testing available on buyer's own formed bodies before purchase
- Installation and operation training provided so the first production run is supervised
Customization Options
- Voltage and phase configured for the destination market
- Mould sets supplied for the wheel types and sizes the buyer produces
- Pressing height adjustment range tailored to the buyer's wheel thickness range
- Machine can be quoted as part of a CRA-500, CRA-800, CRA-600, CRA-700 line
Compared With The Alternatives
| Manual pressing with hand tools or low-pressure hydraulic presses | Manual pressing lacks consistent pressure, leading to variable density and shorter wheel life |
|---|---|
| CRA-800 forming machine | The CRA-800 forms the wheel body; the CRA-600 presses it. They are sequential steps in the same process |
| CRA-700 edge trimming machine | The CRA-700 trims the wheel face after pressing; it is the final step in the line |
Use Guide
- Confirm the formed wheel body is correctly aligned on the lower mould before pressing
- Change the upper and lower moulds when switching between wheel types or sizes
- Check the hydraulic oil level after delivery and refill before first use
- Set the pressing height to match the wheel thickness; too high causes incomplete compaction
- Contact us on WhatsApp for the English operation video if the operator is new to pressing
CRA-600 Buffing Polishing Wheel Pressing Machine FAQ
What is the maximum pressure the machine can apply?
45 tons, which ensures high density and endurance in the finished wheel
How many people are needed to run it?
One operator. The machine handles pressing, pressure control, and cycle timing
Can it press different types of wheels?
Yes. It handles cotton, sisal, airway buffs, nylon, and similar materials with the correct moulds
Do I need other machines to make a finished wheel?
Yes. The wheel must be formed first on the CRA-800 or CRA-300, then pressed here, and trimmed on the CRA-700
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 formed wheel before I buy?
Yes, free sample testing is available. You cover freight and send the specific formed body you plan to press
