FAMAR S.r.l., established in 1972 in Avigliana, near Turin, manufactures 16 different models of vertical lathes specialized in turning, but also in milling, boring, drilling and tapping. Thanks to electro spindles added to the turret, FAMAR machines are able to do the gear cutting and grinding. Furthermore, through the technology of fixed or driven tools fixed on the turrets, FAMAR lathes can even allow the machining of heat - treated materials.
ERGO operating system is quite simple: while the spindle carrier of the “Z” vertical axis, running over closed lubricated guideways, brings the centred spindle to its working position, the movement of the “X” axis is generated by the sliding of the complete carrier over pre-loaded guides, which are positioned over the bedframe. Re - circulating ballscrews guarantee the best precision level of the moving, the highest speed and acceleration, very good loading ability associated with long durability and a simple maintenance. The axis are motorized by asynchronous Brushless motors.
The machine bedframe (FAMAR patent) is made of electrowelded steel; its loop shape guarantees high stability and excellent sturdiness. Being filled with special polymerized concrete, that is responsible for an extraordinary level of vibration absorption as well as thermic stability. This kind of bedframe brings remarkable improvements in comparison with the normal ones, which are made of cast iron: lower tool wear and consequently a better quality of the finished workpieces surface. Comparing this particular closed ring conception with the traditional hanging spindle technology, this solution performs much better results both in repositioning precision and in displacements speed.
The special turret that is fitted on FAMAR machines is flanged on the bedframe. This solution eliminates machining errors due to heat changes. Moreover this system offers greater stability, even during heavy machining, and a more homogeneous spread of the cutting forces.
All FAMAR machines are ergonomic and manufactured according to TPM and EC standards, so that all the mechanical and electronic components can be easily accessed to simplify inspections and maintenance.
The work area and the loading/unloading area are isolated and protected from the machining chips and separated by two sliding metal guards. This set up assures cleanliness and ideal workplace conditions.
The NC system is the digital ground configuration of Siemens 840 D the Fanuc 21T. The highest level components and the use of the most up to date technologies guarantee the best quality of a product, which is the machine of the future.
