ROMI M17 Offers Superior Flexibility, Rigidity and Ease-of-Use

ERLANGER, KY - Romi Machine Tools, Ltd, an industry leader in turning machine technology, has built a reputation on providing customer-driven solutions to a broad array of precision turned-part challenges. The M Series of Combination lathes is yet another step in providing these solutions ever-more flexibly and is ideal for mixed volume, short run operations as well as dedicated high-volume applications.

With a swing of 16.9" and a distance between centers of 43.46", the M17 combines high performance turning and large machining capacity within a compact 107.09" x 49.76" space-saving footprint. Rapid traverse rates of 394 imp (Xaxis) and 295 (Zaxis) mean accelerated machine cycle times and reduced non-cut time which increases overall throughput. Also increasing cycle time is an optional automatic electric drum turret offering a fast 0.48 second station-to-station indexing time. The turret holds eight tools with pockets for square tool holders and bolt-on I.D. tool blocks.

The M17 has a rigid cast iron "H" bed design. All guideways are induction hardened and ground. They feature a Turcite-coated carriage and cross-slide that move smoothly on the solid cast iron bed and saddle guideways, thus ensuring superior rigidity, increased accuracy, improved cutting tool performance and long machine life.

The spindle. A new belt-driven cartridge-style gearless headstock featuring a high-torque 10 hp AC GE Fanuc "P"-type spindle motor with a variable speed drive permits full horsepower at spindle speeds as low as 375 RPM. Three spindle options allow you to match the spindle speed and size to specific production needs. A2 spindles feature rigid mounting, larger through-hole capacities and higher FPM, while Dl Camlock spindles offer quick chuck changing between three- and four-jaw chucks. The A2-5" has a through hole of 2.09" and a speed range of 4 to 4,000 RPM, while the A2-6" and Dl-6 have through holes of 2.56" and 2.09" respectively and a speed range of 3 to 3.000 RPM.

To assure the rigidity required for heavy-duty cutting, the spindle is supported by angular contact ball bearings at the nose and a double-row of cylindrical roller bearings at the rear. The spindle cartridge is lubricated for life, and the spindle design eliminates the need for oil recirculation or refrigeration systems to maintain spindle temperature, thus offering years of reliable performance with reduced operating and maintenance costs.

A rigid tailstock with dual clamping affords rigidity for turning heavy parts or manual large diameter drilling. The tailstock has a large manually operated quill with cast-in tang stop and drill knock-out.

An automated lubrication system, a complete coolant system and splash guards with overlapping doors are standard.

The control. The GE Fanuc 21i-T features the latest technological advancements in a uniquely small space. The 10.4" color LCD and full keyboard conveniently swivel for ease of operation. A shock absorber keeps the control in position when keys are pressed. GE Fanuc CNCs and associated spindle and servo drives have an exceptional reputation for reliability. For example, according to GE Fanuc, sub-system failures per month are nearly unheard of - 0.00495 on the CNC, 0.00099 on the servo drive and 0.00376 on the spindle drive.

Operator-friendly software. Romi Machine Guidance software in the 21i-T is the ideal CNC for operators with varying levels of experience, as it simplifies the transition from manual programming to G code programming. As the operator's skill level rises and/or part geometry complexity increases, the operator can easily move through four levels of part programming generation. These are:

Manual Cutting. The operator uses the electronic handwheels, and the CNC's position registers to cut the part manually. This is the simplest mode, and the moves are limited to X and Z cuts.

Guidance Single Cutting. The operator uses the electronic handwheels, and the CNC's position registers to cut the part. The operator enters additional data and uses one handwheel to cut tapers and radii on the part. In this mode, the axis moves and other commands can be recorded as a part program. The "taught" program can be "played back" to produce additional parts.

Guidance Cycle Cutting. The 21i-T CNC has built-in machining cycles for profiling (rough and finish), grooving, threading, drilling, boring, and rigid lapping. These cycles generate a part program based on information the operator enters, as prompted, to describe the part. The CNC automatically generates the part program, which then can be converted to a standard G code format.

G Code Programming. The 21i-T can be programmed offline or online using G code language, allowing the use of standard G code features available from GE Fanuc.

For more than 70 years and some 140,000 installations Romi's innovation, reliability, dependability and ease-of-use have set it apart - and ahead - of the competition. Romi's Combination and CNC lathes, turning and machining centers are meticulously built at its eight-plant manufacturing complex in Santa Barbara d'Oeste, Brazil, and are sold and supported in more than 60 countries. From its North American Headquarters in Erlanger, Kentucky, Romi provides an unparalleled degree of training, service and support for all Romi machine tool products.
