There are many different types of CNC milling machines. Although there are differences in the composition of different types of CNC milling machines, there are many similarities. The XK5040A CNC vertical lifting table milling machine is taken as an example to introduce its composition. XI Saw 040A CNC vertical lifting table milling machine is equipped with IV four 3MA numerical control system, using all digital AC servo drive. The machine consists of six main parts. That is, the bed part, the milling head part, the worktable part, the cross feed part, the lift part, the cooling and lubrication part. The internal layout of the bed is reasonable and has good rigidity. There are 4 adjusting bolts on the base to facilitate the horizontal adjustment of the machine tool. The cutting fluid storage tank is located inside the machine tool seat. Words：cnc milling service/ cnc precision milling/ high speed milling/ mill parts/ milling/ precision milling
