T70 Mixto Maquijoy Combination Roller

Maquijoy T 70 Combination Roller for Sheet Metal and Wire with 4:1 Gear Ratio

The Maquijoy T 70 is a compact, hand-operated combination roller manufactured in Spain for sheet metal and square wire. Maquijoy has been manufacturing machines and tools for goldsmiths in Zaragoza for over 60 years, having emerged from the long-established company Talleres Tatum. The T 70 is particularly well-suited for smaller goldsmithing and repair shops.

The 70 mm-wide rollers are divided into a flat section of 45 mm for sheet metal and four square wire grooves measuring 3.4 mm, 2.6 mm, 1.7 mm, and 1 mm. They are made of hardened, dimensionally stable steel with an induction-hardened surface and are precision-ground.

A 4:1 reduction gear significantly reduces the effort required for rolling. The frame is made of cast steel and is neatly machined. The rollers run in maintenance-free bronze slide bearings. The crank is included in the scope of delivery.

For safe operation, the roller should be securely mounted on a sturdy workbench. For significant reductions in cross-sectional area, it is recommended to anneal the material between individual rolling passes.
