Years of production 1978 - 1984
The first machines equipped with NC units to be sold under the Miyano name were the CNC-7BC/6BC series.
Arranging a wide, 12-station turret and a large-diameter spindle in parallel gave a machine construction with little thermal displacement, and combining these with a heavyweight bed made from a monobloc casting resulted in a machine that excelled in the heavy-duty cutting of medium to large diameter workpieces.
It is user-friendly bar & chucker machines that fused the automatic lathe technology built up over many years with the latest NC technology at the time. The optional tailstock also allowed the machining of long workpieces.
