Arbe KMT-40 Variable Speed Magnetic Tumbler – 300 Ring Jewelry Magnetic Finisher

The Arbe KMT-40 Variable Speed Magnetic Tumbler is a professional jewelry finishing system designed for fast, efficient polishing of rings, cast jewelry, precious metals, and intricate components. With a capacity of up to 300 rings, this high-capacity magnetic finisher is an excellent choice for jewelry manufacturers, casting facilities, repair shops, goldsmiths, and other high-production environments.

Using powerful magnetic action and stainless steel polishing pins, the KMT-40 reaches into areas that conventional polishing wheels and tumblers can struggle to access, including undercuts, channels, recesses, filigree, settings, and other intricate details.

High-Capacity Magnetic Jewelry Finishing

Designed for demanding professional applications, the Arbe KMT-40 can accommodate approximately 300 rings per cycle, making it ideal for production environments where larger quantities of jewelry need to be processed efficiently.

The system uses up to approximately 850 grams of stainless steel pins. During operation, magnetic force rapidly moves the pins throughout the work bowl, allowing them to contact detailed surfaces and difficult-to-reach areas of jewelry pieces.

Variable Speed Control

The variable speed control gives operators greater flexibility when finishing different types of jewelry and metal components. Adjusting the operating speed allows the finishing process to be tailored to the size, shape, material, and complexity of the pieces being processed.

This added control makes the KMT-40 suitable for everything from detailed jewelry components to larger production batches.

0–60 Minute Timer

An integrated 0–60 minute timer provides convenient control over each finishing cycle. Once the desired operating time is selected, the machine can run for a consistent predetermined period, helping create a repeatable finishing process in busy jewelry production environments.

Ideal for Intricate Jewelry

Magnetic finishing is particularly effective for jewelry with complex surfaces and recessed areas. The small stainless steel pins can reach locations that may be difficult to polish using traditional rotary tumblers or buffing wheels.

The Arbe KMT-40 is ideal for:

• Rings and bands
• Cast jewelry
• Filigree and detailed designs
• Channels and recessed areas
• Undercuts and intricate surfaces
• Pendants and small jewelry components
• Precious metal finishing
• Jewelry manufacturing and production finishing
