The SL series is Colchester-Harrison's slant-bed CNC turning center, sold as the Tornado range and built on high-quality meehanite cast iron with FEA-optimized structure. A 12-station VDI turret works beside an A2-6 or A2-8 spindle under a 15-inch Fanuc 0i-TF Plus control.

Why meehanite cast iron for repeatable turning?

A lightweight fabricated bed flexes under load and grows with temperature, so the part drifts through a shift. The SL series' meehanite casting damps vibration and holds thermal stability, letting the 350 mm diameter stay in tolerance from the first part to the last — the repeatability a production shop relies on when the day warms up.

• 350-550 mm turning diameter, 52-103 mm bar
• A2-6 / A2-8 spindle up to 5,000 rpm
• 12-station VDI turret
• Meehanite cast-iron bed, Fanuc 0i-TF Plus

Against a fabricated-bed lathe, the SL series holds its geometry over a long run — the stability that keeps a shaft or flange in tolerance shift after shift.
