Flexibility through Configurability

Romis new mid-sized CNC lathe: multiple configurations + live tooling.

The new Romi C620 combination lathe achieves maximum flexibility because it can be configured according to customers’ needs.


Romi Machine Tools Ltd. is introducing a new CNC lathe, the C620, to achieve maximum flexibility thanks to its configurability, according to customers’ needs. It’ s available in a variety of headstocks, bed lengths, turrets, tooling and operating choices. The new machines are now shipping in one- or two-meter bed lengths. The swing over the bed is 620 mm, or 24.4 in. A 2- to 8-in. spindle is standard.

The C620 is driven by a Siemens Sinumerik 802 sl with 10.4 in. LCD monitor. Both manual and hydraulic tailstocks are available.

For chucking work, Romi indicates customers usually will choose the one-meter design, which offers a smaller footprint; the two-meter bed length is more suited to shaft work.

Customers who require heavy low-end torque will want the geared headstock, the builder indicates, and parts that demand higher RPM and better finishes will be produced better with the v-belt, direct-drive headstock.

Both bed lengths are available with live tooling options. The C620 can be equipped with an electric disk-type turret drive, with VDI-40 tooling or a servo driven WTO tool turret, so it’s possible to machine parts with static and live tools.

A four-station electric vertical-axis turret drive is available, too, as is a three-position quick-change toolholder.

According to Romi, the geared headstock version of the C620 can be equipped with a hydraulic indexing system, with 72 positions for milling and drilling. With the direct-drive headstock, optional disc brakes make it possible to mill and drill in 360 different angular positions. Rigid tapping is possible thanks to the transmission’s no-play feature.

With the optional Romi Manual Machining package, the C620 Combination Lathe achieves three operating modes, depending on the operator’s skill level.

In Manual Mode, the operator machines parts as on a conventional lathe, using the control apron. In this mode, it’s possible to perform parallel turning, taper turning, radius turning, drilling and grooving can all be performed in Manual Mode.

In semi-automatic Cycles Mode, the machinist installs information on Control for Feed, Speed and Cycle Data through in the “conversational” screens, and approaches the part manually using the control apron. Once he initiates the machining cycle by engaging the Cycle Start button, he’s able to drilling, tapping, grooving, cutoff, threading, and rough and finish turning.

In Teach Mode, the operator programs into the control memory a step-by-step review of the first part to be machined. The control converts these machining steps into a program that can be run automatically on subsequent parts. Manual operations and cycles operations can be saved together into the same program, and stored in the CNC memory or Flash Card.
