FAMAR S.r.l 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.
FAMAR S.r.l 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 preloaded guides, which are positioned over the bedframe. Recirculating 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 axes are motorized by asynchronous brushless motors.
The machine bedframe (FAMAR patent) is made of electro-welded steel; its loop shape reportedly 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.
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 setup assures cleanliness and ideal workplace conditions.
The NC system is the digital ground configuration of Siemens 840 D the FANUC 21T.
