ROMI M 33

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.

Headstock lubrication is temperature controlled using a system that is outside the machine, thereby minimizes heat distortion.

The CNC control panel is mounted on a pendant that is rigidly supported by an overheard arm and is attached to the apron. The pendant and apron are capable of traveling the length of the bed for operator convenience. All controls are outside the guards where they are not exposed to chips and coolant.

A two piece tailstock is standard on all the M33 lathes. The two piece construction allows easy alignment. A dual clamp design means you can do very large diameter drilling using the tailstock. The front mounted quill hand wheel makes positioning of the quill an easy reach from the end of the part.

The two speed manual quill can be quickly moved into position or fine feed can be used for drilling. The tailstock body is positioned using the carriage.

The automatic lubrication system supplies lube oil to the carriage and cross slide. Warning messages are displayed on the CNC to indicate low lube oil level and lubrication system faults.

Romi has also incorporated the latest GE-Fanuc 50 HP spindle drive motor for the M series. The two speed gearbox gives the M 33 maximum torque for heavy cutting with full horsepower at speeds as low as 48 RPM. Spindle speeds are infinitely variable within each range.
