Gantry Milling Machine

X3020

The machine structure design is reasonable, with enough static/dynamic rigidity and good accuracy retention, using reasonable technology to ensure the machining efficiency of the machine.
The machine tool is easy to use and maintain and has sufficient safety.
The main functional parts and key parts of the machine are of high quality, and some of them are famous brand products.
The whole casting adopts HT250 gray cast iron, which is tempered to eliminate stress in time to ensure the minimum deformation.
The guide rail of the worktable is pasted with wear-resisting sheet, the guide surface of the base, beam and column is subjected to high-frequency heat treatment and precision grinding to ensure the transmission accuracy: the hardness of the guide rail can reach HRC48-52.
Table and beam movement are controlled by frequency conversion speed regulating motor, cutting speed is easy to control.
Spindle adopts SCM21 alloy steel precision machining, after quenching and tempering carburizing treatment, with precision bearing, can withstand long-term high-speed operation.
Beam locking adopts hydraulic locking, A single oil pump is used for independent lubrication of bed flat -V rail.
The main rail of the machine tool is equipped with mobile protective cover, and the beam is equipped with an organ type protective cover.
