DECO The productivity of a cam-controlled automatic with the flexibility of a numerical control. TB-DECO Software that guides you from print to programming of precision turned parts on a Windows™ based program. PNC-DECO Major innovations of this control system are : the central clock (electronic camshaft) and virtual electronic cams. – Online programming on a portable PC. – Easy, versatile and rapid use of the system. – Real time calculation of machining times. – Instantaneous program transfer to the NC. – Graphic simulation of tool paths. – ISO language. – No physical angular limits. –...

DECO 20a PNC-DECO PARALLEL NUMERIC CONTROL (concept patented by Tornos SA) The only solution to match the high productivity of a cam controlled automatic on an NC machine. Axes paths are calculated by data processing and stored on tables (virtual cams). A clock synchronizes the reading of these paths (virtual camshaft). Tool correctors are selected automatically and can be adjusted by the operator from the machine’s control panel. This type of control, similar to all DECO, assures maximum reduction of non productive time. Numerous positive experiences with smaller diameters have clearly...

TB-DECO PROGRAMMING SOFTWARE The patented TB-DECO interface has been entirely developed by Tornos. It takes into account all the aspects of the specific programming and machining methods of sliding headstock automatics. Running on Windows, it also offers the easy use of that well known interface. The system is ergonomic and permits simple, logical and rapid programming. A simulator permits a fast display of the paths. Once the programme has been prepared with the software, it can be transferred immediately to the PNC-DECO control. All the programming operations are effected automatically....

DECO 20a KINEMATICS Tornos guarantees an excellent machine configuration to fit our customers needs. Optimal machining conditions are offered by the machine’s ergonomics and simplicity ; with good visibility of the machining area. The unique features of the numerical control permit the following operations with the high productivity of a cam controlled machine : Turning with two tools at the same time, the tools being separately interpolated. Rough turning and finishing in the same operation. Cross operations interpolated with 6 driven spindles and Y-axis for cross-milling, eccentric...

■ Main spindle and counter spindle have program- mable spindle positioning for all kinds of milling operations or other machining requests. ■ Optimized management of feeds and speeds (no excessive efforts on material). Tools enter the material at the ideal moment, no waiting time ■ C-axis function at main and counter spindle Permanent indexing will permit to produce very specific shapes. Each of these characteristics linked to the basic design offer: ■ Powerful and efficient motor drives ■ Outstanding thermal stability ■ Large swarf bins ■ A continuously adjustable coolant flow ■ Clamping...
