Romi's CNC Teach Lathes Can Operate Manually, Automatically

Romi Machine Tools' C Series CNC teach lathes can be operated manually or automatically. The series includes six models ranging from the C 420 — which has a 17" (430 mm) swing-over bed; 4,000-rpm, 12.5-hp main motor; and 39" between centers — to the C 1000, which has a 40" (1,000 mm) swing-over bed; 500-rpm, 45-hp main motor; and up to 197" between centers.

Each Romi C Series lathe is equipped with the Romi Manual Machining Package (RMMP) that allows basic operations to be completed without any type of programming. The company says it is as simple to use as a manual lathe, but has the added capability and productivity of a CNC lathe.

An operator using the RMMP can machine parts in manual mode using the handwheels and also in automatic mode using a joystick and start cycle. The operator can also fill in the fields on the CNC screen, indicating spindle speed, feeds, cutting depth, coordinates and angles, and start the machining with the cycle start button.

All key components of Romi C Series lathes, including the monoblock bed, are designed and built in-house for quality control. The beds are said to feature a strong structure supported by cast-iron columns and are internally ribbed to absorb vibrations during machining. Flat and prismatic guides are hardened and ground to ensure high wear resistance and are self-adjusting to provide permanent contact of the cross-slide over the bed. These features result in high rigidity, stability and precision in machining operations at full power, according to the company.

All C Series models are equipped with a Siemens Sinumerik 828D CNC that features a 10.4" LCD color monitor and provides intuitive conversational programming, operation and machining simulation resources.
