The new line of GGTRONIC turning and milling centres, also designed for use in an unmanned environment, can machine cylinders and complex components up to 4,000 mm in diameter and 20,000 mm in length.
These machines are high-powered turning and milling centres, particularly suited to heavy-duty machining in the precision mechanics sector, to the machining of ship masts, wind turbine masts, turbine shafts, oil pipeline valves, crankshafts and rolls, to the machining of large winch drums, and so on.
One of our key objectives during the design stage were the machine's ergonomic features, as well as ease of clamping, tool visibility throughout the various stages of machining, and the different measurements once the part has been finished.
A forerunner in the movement of the longitudinal axis (Z axis), we have used INA RUE 100 linear roller guideways, high stiffness guideways, and sliding on preloaded roller guide shoes.
Traverse speeds of 20,000 mm/min can be reached using this system.
As for the longitudinal axis, the X and Y axes also slide on preloaded roller guide shoes.
With a B-axis machine, parts can be machined both on 5 sides, in a single setup, or by using all 5 axes to machine any complex profile.
Positioning precision and repeatability, ± 0.01 and ± 0.005 mm, are particularly noteworthy.
The machine structure, built entirely of cast iron, is strong enough to take anti-vibration boring bars, suitable for internal boring to a depth of over 4,000 mm.
