How Does a Roller Tumbler Work?
A Roller Tumbler rotates a barrel on precision-ground urethane bars. As the barrel turns, parts and media roll and cascade against each other, creating controlled contact for finishing. The MT Series Roller Barrel is designed for this rotary action in a compact table-top format.
The rolling action can be adjusted through the available drive configurations. For applications involving delicate parts, the optional variable speed control can help reduce or increase the intensity of the process as needed.
MT Series Roller Barrel for Wet and Dry Processing
The MT Series Roller Barrel uses water-tight barrels that can be used for both wet and dry processing. Wet processing can combine parts, media, water, and compounds for cleaning, deburring, polishing, or burnishing. Dry processing can support polishing, drying, and other finishing applications where liquid is not required.
The Roller Barrel Tumbler can accommodate different barrel sizes on the same roller base, allowing operators to select a capacity suited to the batch. This flexibility makes the system useful for different part sizes and processing requirements.
Mini-Barrel Tumbler Series for Small Batches
The Mini-Barrel Tumbler Series is suited to small batch sizes and small parts. Multiple barrel sizes can be used on the same roller base, allowing the equipment to be configured for different load volumes and part requirements.
The MT Series is available with barrel capacities from 22 fl oz to 8 gallons. This range allows the Mini-Barrel Tumbler Series to support laboratory testing, small production runs, hobbyist work, and R&D applications.
MT Barrels and Available Capacities
MT barrels are available in several configurations, including MT-1, MT-2, MT-3, MT-4, MT-6, and MDT-1. Each barrel has its own dimensions, opening, capacity, and operating speed, while the same roller base can accommodate multiple barrel configurations.
When selecting MT barrels, consider the required capacity, barrel dimensions, part geometry, media load, and process requirements. Additional or replacement barrels and replacement barrel covers are available for the MT Series.
Roller Tumbler for Deburring and Polishing
A Roller Tumbler can be used for deburring, polishing, burnishing, cleaning and rust removal, and scale removal. These processes can be adapted to the part material, media, compound, cycle time, and desired finish.
For small parts, the MT Series Roller Barrel provides controlled rotary movement while keeping the equipment footprint compact. The system can be configured for wet or dry processing depending on the required finishing process.
Roller Barrel Tumbler for Sensitive Parts
The Roller Barrel Tumbler can be used for sensitive and fragile parts when the process is configured appropriately. The optional variable speed drive allows the operator to adjust the rotary action and control how parts interact with the finishing media.
A Roller Tumbler is useful when the application requires controlled movement rather than the vibration-based action of a vibratory finishing machine. Media selection, load level, cycle time, and speed should be matched to the part and desired finish.
Selecting a Barrel Tumbler Machine
A barrel tumbler machine for small batch processing should be selected based on part size, batch volume, finishing objective, wet or dry requirements, available space, and required cycle time. The MT Series supports multiple barrel configurations on the same roller base.
The MT Series is designed for compact processing and can be used where a larger industrial system is unnecessary. Kramer Industries offers the equipment for small production runs, laboratory testing, and R&D applications.
Equipment Features and Process Control
The MT Series base uses precision-ground urethane bars and a standard two-speed drive. An optional variable speed drive is available for applications that require additional process control. The bases are available in domestic and international voltages.
The Roller Tumbler can be configured with additional or replacement barrels and replacement barrel covers. The equipment can therefore be adapted as processing requirements change.
Replacement Barrels and Maintenance
A replacement barrel should match the specific base, barrel model, dimensions, drive arrangement, and application. Kramer Industries provides multiple MT barrel configurations for the same roller base, allowing operators to change capacity as processing requirements change.
When replacing a barrel, verify the model and capacity before ordering. Proper barrel selection helps maintain the intended operating speed, load volume, and compatibility with the roller base.

Frequently Asked Questions (FAQs)
Q1. What does a rotary tumbler do?
A rotary tumbler rotates parts and finishing media inside a barrel so they roll and cascade against each other. This controlled movement can help deburr, polish, burnish, clean, remove scale, and improve the surface finish of parts.
Q2. What are the differences between a vibrating and a rolling rock tumbler?
A rolling or rotary tumbler rotates a barrel around an axis, creating a rolling and cascading action. A vibrating tumbler uses vibration to move the parts and media. The appropriate system depends on the parts, media, batch size, desired finish, and processing requirements.
Q3. What is the best high-end rock tumbler?
There is no single best tumbler for every application. The appropriate equipment depends on batch size, part or rock dimensions, cycle time, desired finish, wet or dry processing, and available space. The MT Series is designed for small batches, small parts, hobbyist work, small shops, and R&D applications.
Q4. What is a Roller Barrel Tumbler used for?
A Roller Barrel Tumbler is used for deburring, polishing, burnishing, cleaning, rust removal, and scale removal. The MT Series can perform these processes using wet or dry methods depending on the application.
Q5. Can the MT Series use different barrel sizes?
Yes. The MT Series is designed to use multiple barrel sizes on the same roller base. This allows operators to select a suitable capacity for different batch sizes and processing requirements.
