  • Highlights
  • Technical data

Interchangeable shuttle pallets The presence of interchangeable shuttle-type pallets without lifting the lower pallet (cutting is carried out at two levels) allows for quick replacement of workpieces, the re-rolling time is no more than 15 seconds

Z-axis acceleration is up to 3g It is important for maintaining a constant distance between the nozzle and the metal sheet at high speeds

Automatic tracking system Allows you to maintain optimal focus with an accuracy of 100 microns, which increases and stabilizes the cutting speed and results in getting a high-quality smooth surface of the cut edge

Linear motors in three axes It improves the accuracy and speed of cutting parts. We guarantee the performance of our machines and confirm this in practice

Cutting head with auto focus Precitec Procutter cutting head guarantee of reliability and quality

Due to technical know-how, we use 1 linear motor in X-axis It avoids delays when synchronizing with the second motor

Composite Y-beam, which is not subject to deformation due to temperature fluctuations Significantly improves the accuracy of machine tools compared to steel and aluminum beams

The X-axis in Navicut machines is located on top, unlike other machines Allows you to avoid sparks on cable routes during cutting

The acceleration set parameter is 28ms, one of the best values among all manufacturers Gives an advantage in the cutting speed of complex parts when many braking-acceleration cycles are required

Large weight of machines, damping system Vibration reduction and work accuracy increase

4 opening doors on both sides of the machine Facilitates the work of the operator in case of need for access to the working field. Possibility of location of the machine anywhere in the production area

CNC from B&R, one of the world leaders in industrial automation These are real-time CNCs that track the position parameters of moving parts up to the 5th derivative. Affects the speed and accuracy of data processing

The Navicut machine control software is supplied by the world leader in this field, Metalix Increases the convenience of the operator, and also allows you to use all the features of the machine

Cabinet system for all Navicut machines with door position control sensor and viewing windows Ensures safe operation

Components of world leaders French linear motors, German compressors, Italian filtration plant. Precitec laser head, IPG laser source, Japanese THK or German INA guides, IGUS flexible cable channels
