Gantry CNC engraving and milling machine

Gantry CNC engraving and milling machine

 Gantry-type CNC engraving and milling machine, including a gantry-type bed, a table, a beam, a vertical feed ram, and a numerical control unit; the gantry-type bed is composed of a base and columns provided on both sides of the base; a beam is erected on both sides The guide rail of the vertical column can slide along it, and the cross beam is connected with the driving device installed on the vertical post; the vertical feed ram is connected with the guide rail on the cross beam through the connection plate and slides along the guide rail, and the connection plate is installed on the cross beam The horizontal drive is connected; the workbench is mounted on the base. The gantry CNC engraving and milling machine body adopts a gantry vertical structure, which can clamp larger workpieces compared to existing fixed beam NC engraving and milling machines. The gantry bed is integrated with the workbench, which not only has good rigidity, but also there is no installation error between the two. It will not affect the machining accuracy for a long time. The double-end drive device is used in the beam, and the center of gravity of the drive center is closer to the beam. Improved machine stability.

Beam guide structure of gantry machining center

 The beam guide structure of the gantry machining center includes a beam, a guide rail and a pressing plate which cooperate with the axle slide plate. The guide rails are respectively located between the stern axle slide plate and the beam and between the press plate and the beam plate. And the value of α is between 30 ° and 45 °. The utility model not only increases the torsional moment and rigidity of the cross beam and the slide plate, improves the heavy cutting ability of the machine tool, but also reduces the influence of the heating of the stern screw on the guide rail. In addition, the utility model changes the traditional sliding guide to a rolling guide, which greatly reduces the friction coefficient, makes it difficult to produce low-speed crawling, and improves the fast-forward speed and acceleration capability of the gantry machining center.
