The SIR 36 is a high-performance automatic bar feeder from IEMCA, specifically optimized for multi-spindle lathes with both 6 and 8 spindles. It is distinguished by its operational philosophy: Simple, Flexible, and Superfast. This feeder is capable of expertly handling round bars ranging from 5 mm up to 36 mm in diameter, with bar lengths supported between $2-500$ mm and $4-300$ mm.

A significant feature is the maximum flexibility available on the market for diameter changeover, achieved through IEMCA’s patented system of adjustable bobbins. The design is highly efficient, allowing for nimbly charged bars and the management of remnant recovery without needing a stock reel, which results in substantial space savings on the ground. The bar changeover time is remarkably fast, taking approximately 30 seconds for a 3300 mm bar. The SIR 36 guarantees the highest speed rotation possible while maintaining stability and is available with either a multi-rack magazine (11 bars plus 200 mm) or a larger bundle magazine (2 tons) to match different production volumes. This combination of speed, flexibility, and space-saving design makes the SIR 36 an ideal solution for maximizing throughput on demanding fixed-headstock multi-spindle applications.
