Gantry milling machine referred to as gantry milling, is a door frame and horizontal long bed milling machine. Gantry milling machine can use multiple milling cutter at the same time processing surface, processing accuracy and production efficiency are relatively high, suitable for batch and mass production in the processing of large parts of the plane and slope. CNC gantry milling machine can also be processed space surface and some special parts.
The gantry milling machine has a similar shape to the gantry planer. The difference is that its beams and columns are loaded with a cutter without a planer but with a spindle box, and the reciprocating motion of the longitudinal table of the gantry milling machine is not the main movement, To the movement, while the rotation of the milling cutter is the main movement.
The Structure of Gantry Milling Machine The gantry milling machine consists of a door frame, a bed table and an electrical control system.
The door frame consists of columns and top beams, with beams in the middle. The beams can be lifted and moved along the two column guides. There are 1 to 2 beams on the beam with a vertical spindle, which can be moved laterally along the beam guide. Two pillars can also be installed with a horizontal spindle of the milling head, it can be along the column for lifting movements. These milling heads can process several surfaces at the same time. Each milling head has a separate motor (power up to 150 kW), variable speed mechanism, operating mechanism and spindle components.
Horizontal long bed with a removable table, and covered with a shield. Processing, the work-piece is installed on the table and with the vertical feed movement.
Gantry milling machines also have some variants to accommodate different processing objects.
gantry boring and milling machine: the beam is equipped with milling and boring milling boring head, the spindle (sleeve or ram) can be used for axial motor feed and fine-tuning device, fine-tuning speed can be as low as 5 mm / min. Can be boring and milling operations.
gantry milling machine: beam with a power head, through the pole with a drill or cutter, to complete the drilling and milling operations.
Gantry milling machine bed is equipped with X-axis guide, gantry milling machine table across the fastening in the bed. The gantry also includes a gantry carriage and a gantry carriage moving on the X-axis guide. Z-axis guide, mounted on the gantry. And the beam is provided with a Z-axis carriage, and the beam is movably clamped on the Z-axis guide through the Z-axis carriage, and the Y-axis guide is also mounted on the beam. Milling device, gantry milling machine milling device activities installed in the Y-axis rails, so that the gantry in the control of CNC control system for X, Y, Z three-axis three-dimensional space milling. The CNC gantry milling machine with high precision milling, drilling, boring, cutting and other operations.
