The CNC gantry milling machine is mainly composed of bed, column, beam, transverse sliding table, worktable, spindle, screw rod, lubrication system, cooling system, numerical control gantry milling machine control operation panel and electronic control system.
There are two processing and walking methods for CNC gantry milling machines: one is fixed beam CNC gantry milling machine, and the other is moving beam CNC gantry milling machine.
As the name implies, the fixed-beam CNC gantry milling machine means that the “door” that looks like a “door” is fixed, and the machining workpieces required by the machine tool are fixed on the worktable, the worktable is movable, and the worktable drags the work piece. Walk to complete the processing task.
The advantage of the fixed beam CNC gantry milling machine lies in its high accuracy. Because the beam and column of the fixed beam CNC gantry milling machine are fixed, the machine has considerable stability, so the machining accuracy of the machine tool is very high. The disadvantage of fixed-beam CNC gantry milling machines is that the processing limitations of the machine tool are large. For example, a fixed-beam CNC gantry milling machine with a gantry span of 3 meters and a worktable of 6 meters can only process 3*6 workpieces. Below meters.
On the contrary, the “door” of the moving beam type CNC gantry milling machine is movable and the worktable is fixed. The moving beam type CNC gantry milling machine fixes the workpiece to be processed on the worktable when it is working, and then the gantry of the machine tool starts to work. In order to complete the processing tasks of the workpiece. The advantage of the moving beam type CNC gantry milling machine lies in the low price of the machine tool. The moving beam type CNC gantry milling machine works by moving the beam and column. The appearance design of the machine tool is two beds and one beam, and the two columns are walking on two beds. Therefore, the weight of the machine tool is relatively light, which reduces the cost of the machine tool and the price of the machine tool.
