Johnford ST Series horizontal turning centers feature a one piece, 60˚ slant-bed torque tube design. The torque tube, or hole cast through the center of the slant bed, maximizes rigidity and dissipates heat. For optimum strength and accuracy, the machines are cast from rigid Meehanite iron.
Swing over the bed for the 28-machine series ranges from 31″ (533 mm) to 47.2 ” (1,199 mm). Swings over the cross slide are 23.6″ (600 mm) to 39.4″ (1,000 mm). Distance between centers begins at 40″ (1,016 mm) and is 400″ (10,160 mm) on the largest machine.
