The Eldorado M75-48-R1 is a single-spindle reaming machine designed for lower-volume gun barrel manufacturers. Our standard DeHoff reaming machine has two spindles, automated barrel loading, and automated tool handling. The new Eldorado reaming machine has only a single spindle and requires manual loading of the barrels and reamer tooling. This makes the Eldorado machine smaller and less expensive, which makes it perfect for low-volume barrel manufacturers.
The Eldorado M75-48-R1 has a maximum reaming diameter of 0.75 inches (19 mm) and a maximum barrel length of 36 inches (914 mm). The machine features hardened steel box ways and hand-scraped spindle housings (versus linear guide ways and milled surfaces). This results in superior vibration damping, extended tool life, and improved surface finish.
