Purpose of equipment: 
CNC drilling and milling machine series are mainly used for efficient drilling and milling of flanges, discs, rings, plates and other workpieces with a thickness within the effective range. It can drill through hole and blind hole in single material parts and composite materials. Machine tool processing process digital control, operation is very convenient. Can realize automation, high precision, multiple varieties, mass production.

Equipment structure: 
The whole casting equipment is mainly composed of side beam, table, gantry, mobile sliding saddle, drilling and milling power head, automatic lubrication device, protective device, circulating cooling device, digital control system, electrical system and so on. The machine has high positioning accuracy and repeated positioning accuracy. 
1. Casting side beam and worktable: 
The whole casting material of the side beam and the worktable is gray cast iron (HT**0), which is finished after secondary tempering and vibration aging treatment, with good rigidity and no deformation. The worktable is constructed by casting. 
2. Moving saddle: 
The moving saddle is a precision cast iron structure, and the saddle is equipped with a precision ball screw pair with ultra-high bearing capacity and a high-precision planetary reducer connected with a servo motor, which drives the drilling power head to move in the Z-axis direction, and can realize the fast forward, work forward, fast back, stop and other actions of the power head. With automatic chip breaking, chip withdrawal, pause function. 
3. Drilling power head: 
The drilling power head adopts a special servo spindle motor, through the gear synchronous belt deceleration to increase the torque to drive the precision spindle, the spindle adopts stepless transmission, the spindle is equipped with pneumatic tool changing system, so that the tool replacement is quick and convenient, the feed is driven by the servo motor and ball screw. X and Y axes can be linked, using semi-closed loop control, can realize linear and circular interpolation function. The spindle end is a BT*0 cone hole, which can be drilled with high speed U. 
4. Automatic lubrication device and protective device: 
The machine tool is equipped with a displacement type automatic partial pressure lubrication device, which can automatically lubrulate the moving parts such as guide rails and lead screws, without dead Angle, and ensure the service life of the machine tool. The X-axis and Y-axis of t
