Key Features & Benefits

Our high-efficiency centrifugal barrel tumbler feature durable design and customizable high speed polishing solutions to meet small and precision parts finishing requirement.

⚡

Heavy-duty Motor

The CB40 runs on a 4.0 kW motor with a frequency inverter (VFD), allowing stepless speed control from 0 to 220 rpm. Variable speed matters because different part materials and target finishes require different centrifugal forces — softer metals and delicate parts run at lower speed; aggressive deburring of hardened steel uses higher rpm. The VFD also enables soft start, reducing mechanical stress on the drive system and extending machine service life.

  • High-efficiency motor design
  • Consistent performance
  • Reduced energy consumption
⚡

48 Independent PU-Lined Barrels

Each of the 48 barrels is lined with a removable polyurethane insert. The PU lining cushions part-to-part contact to protect delicate surfaces, and absorbs vibration to reduce operating noise. Barrels are removable and interchangeable — an optional second set of 48 barrels allows pre-loading while the machine is running, cutting idle time between batches to near zero.

  • Durable design materials
  • Noise reduction technology
  • Extended service life
⚡

Compact Footprint, High Output

Total machine footprint is 1,425 × 1,000 mm with a 40 L capacity across 48 barrels. The multi-barrel layout means you can run up to 48 different part types or batches simultaneously in separate chambers, preventing cross-contamination between part types. This is a practical advantage for jewelry workshops and medical device manufacturers running mixed production with strict batch traceability requirements.

  • Variable speed control
  • Material-specific settings
  • Precision finishing control

Frequently Asked Questions

Find answers to common questions about our products.

What is a Centrifugal Barrel Tumbler Machine?

+

It is a high-energy mass finishing machine that uses rotating barrels mounted on a turret to generate centrifugal force for rapid polishing, deburring, and cleaning. The controlled barrel action delivers consistent results and is ideal for small, delicate, or high-precision parts.

What are the key advantages of centrifugal barrel tumblers over vibratory machines?

+

  • Faster processing: typically 4–10× shorter cycle times

  • Higher surface quality: can achieve a bright to mirror-like finish

  • Ideal for small, fragile, or complex parts: controlled action minimizes part damage and improves consistency

What materials can be processed with this machine?

+

It can process metal, plastic, ceramic, and even 3D-printed parts. Typical applications include medical instruments, aerospace components, jewelry, and watch components.

What sizes and capacities are available?

+

A typical configuration includes 48 barrels with a total capacity of 40 liters. Each barrel holds about 1 liter, making the system ideal for multi-batch and small-batch processing, while still supporting industrial-scale finishing with high throughput.

Can the machine be automated?

+

Yes—models are available with PLC control, frequency converters (VFDs), and automated unloading. These options improve process consistency, reduce labor, and make it easier to integrate the machine into automated production lines.

How does the CB40 differ from the CB30A and the standard CB series with automatic unloading?

+

The CB30A (30 L, 4 removable barrels) suits very small batches and maximum batch flexibility — typically dental labs and jewelry workshops processing one SKU at a time. The CB40 (40 L, 48 barrels) provides higher throughput with more simultaneous batches, while keeping each barrel small enough for delicate parts. The standard CB series with automatic unloading (30–320 L, 4 large barrels) is designed for larger parts and higher volume where automatic discharge reduces manual handling. If you are processing small, mixed batches of delicate parts, the CB40 is typically the better choice over the 4-barrel automatic-unload models.

What media and compounds are compatible with the CB40?

+

The CB40 is compatible with ceramic tumbling media (triangle, cylinder, star cut shapes), plastic tumbling media (cone, triangle, nipple shapes), stainless steel shot and pins, porcelain media, and walnut shell or corn cob for dry polishing. The specific media selection depends on your part material and target finish. Inovatec can recommend the correct combination based on a part sample before purchase.
