DB Series – Industrial Grade, Tub-Style, Floor Model, Vibratory Tumbler

DB Series Industrial Grade Tubs | Vibratory Finisher for Industrial Deburring and Polishing

The DB Series Industrial Grade Tubs are floor-model vibratory finishing machines designed for regular-use mass finishing applications. This Vibratory Finisher is available in two sizes for different batch requirements and is designed for users who need an economical, durable system for deburring, polishing, burnishing, cleaning, and other surface-finishing operations.

The tub-style design provides a practical solution for longer parts and larger batches. Kramer Industries offers the DB Series as a starter system for manufacturers who are new to mass finishing or need a reliable machine for regular production work.

Vibratory Finisher for Mass Finishing

A Vibratory Finisher uses controlled vibratory motion to move parts and finishing media together. As the parts move through the media, repeated contact helps remove burrs, machining marks, scale, rust, and other surface imperfections.

The DB Series is designed as a regular-use tub vibrator and can be used for both wet and dry processing. Its tub configuration provides a longer processing area than many bowl-style systems, making it useful when the parts being processed are long or when the application requires a larger working area.

Kramer Industries designed the DB Series with heavy-gauge steel construction and a rust-preventive enamel finish. The tubs are lined with durable polyurethane, helping protect the equipment during repeated finishing cycles.

DB Series Industrial Grade Tubs for Different Batch Sizes

The DB Series is available in the DB300 and DB650 models. The DB300 provides a 3.0 ft³ capacity, while the DB650 provides a 6.5 ft³ capacity. The two configurations allow users to select equipment according to batch size and production requirements.

The DB Series can support both shorter and longer finishing cycles. This flexibility allows the same equipment category to handle different production requirements, from quick parts testing and smaller production runs to scale-up production.

For manufacturers evaluating a Vibratory Finisher, machine capacity should be considered together with the part size, media volume, workpiece loading, and required finishing time. The tub-style configuration can also be useful when parts require additional length within the finishing chamber.

Vibrating Polisher for Deburring and Polishing

A vibrating polisher works by creating movement between the workpieces and the selected finishing media. This repeated contact can produce a controlled finishing action across the exposed surfaces of the parts.

The DB Series can be used for deburring and polishing operations, as well as burnishing, cleaning, rust removal, and scale removal. The appropriate media and compound can be selected according to the material and surface result required.

When choosing a vibrating polisher, manufacturers should consider whether the process will be wet or dry, the type of material being finished, the amount of material removal required, and the desired final surface condition.

The DB Series includes a complete fluid circulation and recirculation system, including the pump, fluid container, hoses, and fittings. This supports wet processing when liquid compounds or other process fluids are required.

Vibratory Tumblers for Wet and Dry Processing

Vibratory tumblers can be configured for different finishing processes depending on the equipment, media, compounds, and workpiece. The DB Series supports both wet and dry processing, providing flexibility for different production requirements.

Wet processing can be used when a liquid compound is required for cleaning, rust inhibition, lubrication, or another finishing function. Dry processing can be selected when the application does not require water or liquid compounds.

The DB Series also provides a compact footprint compared with the processing capacity offered by the tub configuration. This can make the equipment practical for production areas where floor space needs to be considered alongside finishing capacity.

Optional Tubular Rotary Separator Attachments can be connected to the DB tub outlet for parts and media separation. Tub dividers are also available as an option when additional separation within the tub is required.

Vibratory Tumbling for Longer Parts

The tub design is particularly useful for parts that may not be well suited to smaller bowl-style equipment. Vibratory tumbling in a tub allows longer workpieces to move through the finishing media while maintaining contact throughout the processing cycle.

The DB Series can be used for small batch production runs, cellular manufacturing, quick parts testing, and scale-up production. This range of uses makes the equipment suitable for manufacturers developing or expanding a mass-finishing process.

For longer parts, selecting the appropriate media size is important. Media should provide sufficient contact with the workpiece while avoiding lodging in holes, slots, or other openings. The finishing compound and process time should also be selected according to the material and required finish.

Large Vibratory Tumblers for Production Applications

Large vibratory tumblers are commonly used when production requirements exceed the capacity of smaller bench or bowl systems. The DB650 provides a 6.5 ft³ capacity and is designed for larger batch requirements than the DB300.

Large vibratory tumblers should be selected based on more than machine volume. The actual part size, number of parts per batch, media-to-part ratio, finishing objective, and required cycle time all affect the appropriate machine size.

The DB Series can also be useful when a manufacturer needs to test a finishing process before moving toward larger-scale production. The combination of two available capacities and flexible processing options allows the system to support different stages of production.

Selecting the Right Vibratory Finishing System

The right vibratory finishing system depends on the parts being processed and the result required. A Vibratory Finisher may be selected for deburring, polishing, burnishing, cleaning, scale removal, or rust removal, while the machine size should be matched to the batch requirement.

Part geometry is another important consideration. The DB Series tub configuration is particularly useful for longer parts and applications where a tub-style machine provides more suitable processing space.

Media selection also affects the final result. Ceramic, plastic, synthetic, stainless steel, and other media types can provide different levels of cutting and polishing action. The appropriate media should be matched to the part material, starting surface condition, and required finish.

Kramer Industries provides a range of vibratory finishing systems and finishing media, allowing the equipment and process to be matched to different manufacturing requirements.
