Horizontal Turning Center Features Thermal Compensation

Romi’s new GL 250 horizontal turning center features thermal compensation with sensors to maintain stable, dimensional results. According to Romi, the use of sensors provides accurate, real time compensation as opposed to compensation based on pre-defined algorithms. The result is more accurate machining over extended periods of time when the machine temperature increases.

The GL 250 has a maximum cutting diameter ranging from 11″ (282 mm), and a z-travel of 23.6″ (600 mm). The new machine is designed for medium- to high-production environments and features high power, torque and feed force, in addition to rigidity and precision attributed to the monoblock base.

Additionally, the new turning center is constructed with durable roller ways on all axes to produce high rigidity. A built-in spindle motor with a chiller incorporated and direct drive servo-motors reportedly facilitates high response speed, accuracy, less vibration and lower maintenance requirements. Romi says chilling the motor increases life expectancy and produces less thermal expansion.

The GL 250 also features a tailstock that is programmable and servo-driven. Position, speed and force are determined directly via the FANUC controller that reduces setup time. The turning center also inclues a 12-station turret with a choice of fixed tools with a Romi disk, driven tools with a VDI (Verein Deutscher Ingenieure) or BMT (base-mounted turret) disk, driven tools with y-axis or dual spindle with driven tools and y-axis.

The CNC control features a FANUC Oi-TF with 15″ LCD touchscreen and Fanuc 32iB with 19″ LCD touchscreen for dual spindle version machines and is the newest generation of FANUC’s Series iHMI. It is designed to produce faster, more accurate performance for turning applications with separate areas on the main screen for planning, machining, improvements and utilities. Functions are said to be accessible with just two clicks, and the system comes standard with an Ethernet interface, as well as a compact flash card and USB ports.
