CNC gantry milling machine is a milling machine with a gantry frame and a long horizontal bed. The CNC gantry milling machine can use multiple milling cutters to process the surface simultaneously, with high machining accuracy and production efficiency. It has the characteristics of long service life, low energy consumption, high control accuracy, strong anti-interference ability, and can be manually adjusted under automatic control conditions, making it easy to operate. Suitable for processing large workpieces on flat and inclined surfaces in batch and mass production. The CNC gantry milling machine can also process spatial surfaces and some special parts.

So what standards should be considered when choosing a CNC gantry milling machine? The specific introduction is as follows:

(1) According to whether the processing part is a frame shaped plane or steps of different heights, a CNC milling machine with a point position linear system can be selected.

(2) According to the requirements for part processing, on the basis of general CNC milling machines, add a CNC indexing head or CNC rotary workbench. At this time, the machine tool system is a four coordinate CNC system, which can process spiral grooves, blade parts, etc.

(3) Select according to the accuracy requirements of the processed parts. China has established accuracy standards for CNC milling machines and CNC gantry milling machines. From the perspective of accuracy selection, general CNC milling machines can meet the processing needs of most parts. For parts with high precision requirements, CNC gantry milling machines should be considered.

(4) If the processing part is a curved surface contour, the selection of a two coordinate linkage and a three coordinate linkage system should be based on the geometric shape of the surface.
