Tsune

What Tsune does

Tsune America LLC, headquartered in Edinburgh, Indiana, is the sole North, Central, and South American distribution partner of Japan-based Tsune Seiki, a brand with more than 100 years of industrial metal-cutting heritage. Founded in 2005 (with prior operations tracing to 1996 as Rohbi America LLC), the company manufactures and distributes CNC automated circular sawing systems for ferrous and non-ferrous metal cutting, serving industrial manufacturers including steel service centers, metal fabrication shops, aluminum extrusion companies, and automotive suppliers. Tsune America is the only manufacturer in its segment that produces both the cutting machines and the consumable blades they use, through its subsidiary TSB LLC (founded 2011, expanded 2023), creating a vertically integrated equipment-and-consumable model.

The company's core technology stack includes AC servo motors with ball-screw precision feeding, the proprietary TSUNE Mist coolant system, automatic clamping, and integrated blade manufacturing — combining into 13 machine models, 150+ configurations, and over 100 blade SKUs across product families such as Hi-Tech, Hi-Performance, Heavy Duty, TSL TigerSaw, TSL TigerServo, and the Compact Series, with power ranging from 1.5kW compact units to 37kW heavy-duty systems. Recent additions include the TMB-53 servo-driven chamfering machine extending beyond core circular sawing. The Edinburgh, Indiana facility operates on solar power, supporting a low-overhead manufacturing footprint.

Tsune America's go-to-market is enterprise field sales supported by distributor networks, with a named engineering sales team covering the US and a dedicated Monterrey-based engineer for Mexico, Central, and South America. Revenue mechanics include machine sales, consumable blade sales (via TSB), parts, and service/installation/training — with quote-based pricing and Net 30 payment terms typical of industrial B2B. The company claims 1,000+ active customers across the Americas, indicating a distributed rather than concentrated revenue base.

Core offering

Tsune manufactures and sells high-production CNC automated circular sawing systems for industrial ferrous and non-ferrous metal cutting, including 13 machine models (ranging from a 1.5kW TKA50 to a 37kW TK5C-260G), the TMB-53 automatic chamfer machine, and a line of US-manufactured circular saw blades. The company also provides replacement parts, installation, training, and ongoing technical support from its Edinburgh, Indiana headquarters serving the entire Americas.

Product overview

Tsune is the industry leader in high-production circular sawing systems for both ferrous and non-ferrous applications. The product portfolio consists of 13 machine models organized into two main categories: Ferrous Saws (TKA50, TK-80GL, TK130GL, TK160GL, TK200GL, TK5C-260G) designed for cutting iron, steel, and other ferrous metals; and Non-Ferrous Saws (TKA50SC, TK5M-90GL, TK5M-150GL, TK5M-260G, TK2M16GII) designed for cutting aluminum, copper, and other non-ferrous materials. Additionally, Tsune offers the TMB-53 high-precision automatic chamfer machine and a complete line of circular saw blades (Ferrous Blades and Non-Ferrous Blades) specifically engineered to work with their machines. This integrated approach, where Tsune manufactures both the cutting equipment and the blades, allows them to control and optimize the entire cutting process for maximum performance.
