MASTURN 550i Universal centre lathe with CNC system
Simple machines suitable for piece and small lot production parts.
High precision, performance, easy operation.
Constant cutting speed – part machining of high quality.
Graphic simulation of machining.
Possibility of machining by means of manual control as on conventional lathe or via automatic cycles with CNC system support running on the basis of fixed cycles.
Program can be written as contour programming or DIN programming.
Cutting conditions and geometrical data of the part shape are entered via keyboard in control system which processes them automatically.
On demand, the software for creation of programs and their realization in your PC is available.
