What are the advantages of precision machining about precision machining CNC milling machine in various forms, different types of CNC milling machine in the composition although there are differences, but there are many similarities. The following XK5040A type CNC vertical lifting table milling machine as an example to introduce its composition. Ⅺ saw 040A type CNC vertical elevating table milling machine with Ⅳ four 3MA CNC system, using full digital AC servo drive. The machine tool consists of six main parts. That is, the bed part, milling head part, table part, cross feed part, elevating table part, cooling, lubrication part. The internal layout of the bed is correct, with good rigidity, the base is equipped with 4 adjusting bolts, which is convenient for horizontal adjustment of the machine tool, and the cutting fluid storage rags are located inside the machine base.

1, cooling system. The cooling system of the machine tool is composed of cooling pump, outlet pipe, return pipe, switch and nozzle, etc. The cooling pump is installed in the inner cavity of the machine base, and the cooling pump will beat the cutting fluid from the reservoir inside the base to the outlet pipe, and then sprayed out through the nozzle to cool the cutting zone.

2, lubrication system and mode. The lubrication system is composed of manual lubrication oil pump, oil distributor, throttle valve, oil pipe and so on. The machine tool adopts cycle lubrication method, using manual lubrication oil pump, through the oil distributor to lubricate the spindle sleeve, longitudinal and transverse guideway and three-way ball screw to enhance the service life of the machine tool.
