- ①Longmen boring and milling machine: a milling and boring head can be milled and bored on the beam. The main shaft (sleeve or ram) can be fed axially and has a motion fine adjustment device. The fine adjustment speed can be as low as 5 mm/min. Can perform boring and milling operations.
- ② Gantry drilling and milling machine: a power head is installed on the beam, and a drill or milling cutter is installed through the post to complete the drilling and milling operations.
The gantry milling cnc machine bed is equipped with X-axis guide rail, and the gantry milling machine worktable is fastened across the bed. The movable spanning frame above the worktable is provided with a gantry frame. The gantry frame further includes: a gantry frame carriage, which is movably clamped on the X-axis guide rail. The Z-axis guide rail is installed on the gantry frame. The crossbeam is provided with a Z-axis carriage, the crossbeam is movably clamped on the Z-axis guide rail by the Z-axis carriage, and the Y-axis guideway is also installed on the crossbeam.
Milling device, the milling device of the gantry milling machine is movably installed on the Y-axis guide rail, so that the gantry frame is milled in the three-dimensional space of X, Y and Z under the control of the numerical control circuit control system. The CNC gantry milling machine has high-precision operations such as milling, drilling, boring and cutting.
The main parameter of the gantry milling machine is the width of the table, and there are also parameters of the gantry width.
If the model is SK2015-3 CNC gantry milling, the gantry width is 1.5 meters, the table length is 3 meters, in other words, it can process 1.5 wide and 3 meters long workpieces.
