Romi’s line of CNC lathes offers users outstanding flexibility and can be used for numerous specialty applications. The C 420 and C 510 lathes specifically are ideally set up for manufacturers who are machining gun barrels. 


The C 420 features a distance between centers of 39 in. (1 m), while the C 510 has a generous 59 in. (1.5 m) between centers. These ample sizes give manufacturers great flexibility in the length of the work they can machine, which is critical to gun barrel manufacturing.


Both models are equipped with a Siemens Sinumerik 828D CNC. The operator-friendly control features a 10.4-in. LCD monitor and excellent resources for creating and editing programs. It is the perfect solution for shops that are faced with a great variety of sizes and customization inherent to gun barrel manufacturing.


Key features that help make the Siemens control an ideal choice for this application include canned cycles for turning and drilling, linear and circular interpolation functions, thread opening functions, reference functions, coordinate systems, 256 pairs of tool wear offsets, a tool life cycle manager, background editing and excellent resources for simulation of 2D and 3D machining. Each Romi C Series lathe is equipped with the Romi Manual Machining Package (RMMP) that allows simple operations to be completed manually without any type of programming.


Flexibility and versatility are enhanced with the choice of a pneumatic or hydraulic tailstock, and the ability to utilize customized or specialty work holding devices and steady rests. The machines were built based on an “open design" so that shops can customize many features as needed.


In addition to flexibility in setup, Romi machines exhibit outstanding rigidity. All key components of Romi C 420 and C 510 Series lathes, including the robust monoblock bed, are designed and built in house for complete control and assurance of manufacturing quality. The beds feature a robust structure supported by cast-iron columns and are internally ribbed to absorb vibrations during machining.
