LT1250

 

Computer numerical control lathes are modern metal cutting machines, full of technological opportunities. They are suitable for processing parts with highly complex surfaces where the requirements for dimensional accuracy do not tolerate any deviation. These lathes are used in a variety of serial productions in the field of mechanical and automobile engineering, and many others, of course.

We offer two types of CNC machines: LT and LCC.

The CNC machines of LCC type can be implemented with C–axis motor driven turret. Their speed control is infinitely variable, while the machines of LT type are equipped with a headstock with 3 or 4 speed range changes where the switching between the speed ranges is done manually.

Usually, simpler systems are used for the main motor control. All modern CNC systems have built-in additional functions to implement simple cycles, and thus they are called cyclical controlled. Cyclical controlled lathes, just like all numerical machines, are characterized by great processing accuracy and high efficiency. They are designed in such a way that their service is easy and convenient – their processing and cycles are easily reached, without any serious knowledge of CNC system programming being required.

They are fully implemented in line with the customers’ requirements on CNC systems and the necessary equipment.

For the machine’s computer numerical control system, the client is allowed to choose among the latest versions of the systems of Fanuc, Siemens, Fagor, or Hiedenhein.
