Whitney created horizontal milling machine in 1818; In order to mill the spiral groove of twist drill, American Brown created the first universal milling machine in 1862, which is the prototype of lifting table milling machine; The gantry milling machine appeared around 1884; In the 1920s, semi-automatic milling machine appeared, and the worktable can complete the automatic conversion of "feed fast" or "fast feed" by using the block.

Gantry milling machine has enough rigidity, high efficiency, easy operation, simple structure, comprehensive performance and other characteristics.

Its specific performance characteristics vary according to the type, model and manufacturer, which is closely related to the technology used. Taking SK Series three-axis CNC gantry milling as an example, its performance features are as follows:

1. The end milling head is equipped with tx400 heavy gantry milling head, double rectangular guide rail, strong rigidity;

2. The milling head is equipped with ball screw, pneumatic broach device and servo motor drive;

3. The side milling head is equipped with V5 type gantry milling head, equipped with independent lubrication device, and the lifting is driven by ordinary reducer with variable frequency speed regulation;

4. Conventional milling / NC milling one key conversion three-axis CNC system, which can be programmed and operated manually by using the extended panel, is highly realizable in the actual machining process;

5. Taiwan ball screw is equipped on the bed, beam and end milling head, which is driven by servo motor;

6. Equipped with synchronous belt and synchronous wheel;

7. Hand held electronic hand wheel unit, convenient for three-axis tool setting;

8. The unique cross beam lifting safety interlock device ensures the repeated positioning accuracy of the machine tool;

9. The cycloidal pump set of taibiao has low failure rate due to continuous lubrication.
