Romi Machine Tools’ flexible C620 CNC lathe features a variety of headstocks, turrets, tooling and operating choices. Swing over the bed is 620 mm (24.4"), and an A2-8" spindle is standard. The lathe is also equipped with the Siemens Sinumerik 802 sl, which features a 10.4" LCD monitor.
The machine is available in 1- or 2-m bed lengths and with live tooling options, The 1-m bed features a smaller footprint and is suited for chucking work while the 2-m bed is suited for shaft work.
The geared headstock version can be equipped with a hydraulic indexing system with 72 positions for milling and drilling operations. It is suited for users requiring heavy, low-end torque. The V-belt, direct-drive headstock is suited for parts requiring higher rpm and better finish, the company says. With the direct-drive headstock, an optional disc brake system enables milling and drilling operations in 360 different angular positions. The transmission includes a no-play feature that enables rigid tapping. Both manual and hydraulic tailstocks are available.
The lathe can be equipped with an electrically driven, disk-type turret with VDI-40 tooling or a servo-driven WTO tool turret, which enables machining with static and live tools. A four-station, electrically driven, vertical-axis turret is also available, as is a three-position quick-change toolholder.
With an optional manual machining package is available, the lathe can be used in manual, cycles or teach mode, depending on operator skill levels, the company says.
Filling Bins While the Building is Empty
Over the past decade, technology has advanced to the point that lights-out machining is more seamless than ever
before, with built-in safety systems and even the ability to switch from one part to another in the middle of the night.
