Complete machining
The TNC 640 features an extensive package of cycles for milling, drilling, boring, grinding, and turning operations. It also provides special cycles for complex applications such as interpolation turning and hobbing. All of this functionality can be programmed with Klartext functions and cycles.
Optimal machining
The OCM option optimizes roughing processes, using special trochoidal milling cycles to machine any countour with high efficiency. Productivity is significantly increased, while tool wear is considerably reduced. The optimal cutting data are determined by an integrated cutting-data calculator.
Exceptional availability
Dynamic Collision Monitoring (DCM) monitors the work envelope during all operating modes and stops traversing movements before a pending collision. DCM therefore allows optimal use of the machine envelope, preventing machine damage and costly downtime.
Efficient workstation
Extended Workspace seamlessly brings PCs and external applications to the control's screen. The comfort version adds an additional display to the work area, while the compact version offers an extra application window inside the 24-inch widescreen.
