Design features

The cast frame

The high rigidity of the machine is achieved through a cast 45° inclined frame made of the patented material MEEHANITE strength of which is 2 times superior to gray iron.

Up-to-the-minute CNC conversational mode

The touch control system is developed on the basis of the powerful and flexible Siemens platform. It is designed for maximum performance and provides everything necessary for fast and efficient production:

  • Conversational mode for simple programming.
  • A full set of production cycle programming software.
  • Hot keys and resource control.
  • G-code programming and editing that is compatible with Fanuc, Siemens and Haas G-codes.
  • Automatic calculation of dimensions missing from the drawing.
  • Real-time visualization available while programming.
  • Modeling of 3D solids.

Unique traveling column design that features high rigidity with small footprint

Heavy-duty turret head with hydraulic fixation

High-tech brushless electric motors

  • Brushless alternating current servomotors
  • Rare-earth magnets provide higher torque.
  • DriveClic high-resolution sensors.
  • Totally sensor controlled – no access to reference positions needed.
  • High-tech cables from Siemens.

Smooth movement and rapid traverse

Movements are smooth and rapid traverse can increase up to 15 m/min; extra endurance is provided by sliding boxways that feature special Turcite B anti-friction way and gib liners.

Systematic testing of mechanics

  • Test run time – 100 hours
  • Measurements and temperature changes are recorded also during the night-time work
  • More than 89 different inspections for mechanics
  • Precision granite surface plates and indicators are calibrated annually
  • Full cooling system check
  • Each bolt is tightened to its specification and marked
  • Customary process upgrades

Full electronic quality control of each machine

  • Laser calibration of all 3 axes by Renishaw.
  • Renishaw Ballbar system tests.
  • Electronic balancing of all rotating components.

Precision and performance quality control

  • A sample part Circle Diamond Square cutting test.
  • Exact sample part measurements made after the test.
  • Full test report given after checking the sample part.

International quality certificate delivered with every machine

  • Laser calibration report
  • Ballbar test calibration report
  • Circle Diamond Square Test sample
  • Quality certificate assigned by Manufacturer, Chief Inspector, and Electric Engineer
