Gentiger GT-138V



Optimal Machine Structure

The GT-138V features a specially designed T-shaped machine structure for superior rigidity. The width of the column is the same as the base.
The table is independently installed on the base, and fully supported through the entire stroke, assuring maximum accuracy and dependability. Long term accuracy at high speed machining is assured.

Lifetime Accuracy

All castings are stress relieved and seasoning treated for long term accuracy and long service life.

Three Axes Linear Guideway

The three axes are equipped with extra heavy duty roller-type linear guideways, ensuring superior dynamic accuracy and a long service life.
The extra powerful servomotor drive greatly reduces machining time for large molds while increasing profitavility.
Three Axes Feedrates:
20m/min. rapid feedrate
20m/min. cutting feddrate
Positioning Accuracy: 0.005mm/Full Stroke. (ISO-230-2)
Reoeatability: < 0.004mm/Full Stroke. (ISO-230-2)
Cutter needs to be dynamically balanced to within G2.5.
