Electrical equipment
The machine is completely controlled with the CNC control system in 4 axes with possibility of circular and linear interpolation. By use of the new and up-to-date components is the long life running reliability guaranteed.
Control system
The machine is equipped with control system HEIDENHAIN i530 including colour monitor, portable auxiliary control panel with an electronical hand wheel. Control panel is placed on a rotation holder on lift platform.
Motors
Drives of the transports are equipped with fully digital AC motors Heidenhain EcoDyn. Every axe is equipped with the separate drive in the 5-drives version the best solution. Drive of the spindle is new and controlled with new DC drive.
Measuring
Axes X, Y, Z, W are equipped with linear opti-electronic sensors.
Axe B (table rotating) is equipped with rotation sensor.
Revolutions of the spindle are measured by IRC sensor.
Limit switches Balluff check all the limits.
Position of W and B axe is indicated on the control panel
