ROMI M 20

The Romi M series is the latest version of the technology pioneered by Romi since the early 1990’s. Romi has manufactured more combination lathes than any other manufacturer. Romi combination lathe technology has now been combined with GE Fanuc reliability to create the most advanced combination lathe ever built.

Software developed by Romi and GE/Fanuc gives powerful conversational programming capabilities to the 21i-T control that have not been available on any other lathe. The 21i-T retains the ability to function as a G code control. The fiber optic cable connection to the servo amplifiers as well as the compact design makes the 21i-T the ideal control for this type of lathe. A color monitor enhances visibility and ease of operation.

All machines in this series have Romi’s patented apron technology. All controls are outside the guards where they are not exposed to chips and coolant. The apron can be attached or detached from the carriage as selected by the operator. This allows automatic operation without having the apron travel longitudinally with the carriage. Attaching the apron also allows the operator to choose the most comfortable operating position during manual machining and set up. The joystick can be used for facing and turning cuts at selected feeds and speeds.

A two piece tailstock is standard on all the M20 lathes. The two piece construction allows for easy alignment. A dual clamp design means you can do very large diameter drilling using the tailstock.

The automatic lubrication system has the oil fill port conveniently located on the front of the machine. Warning messages are displayed on the CNC to indicate lube oil level low and lubrication system faults.

Romi has also incorporated the latest GE-Fanuc spindle drive motor for the M series. This “P” type drive has an 8:1 constant horsepower output. That gives the M 20 series full horsepower at speeds as low as 275 RPM. The advantages of the “P” drive have allowed us to eliminate the gearbox without significant loss of torque at the spindle
