Automatic tool change High Speed CNC Plate Drilling and Milling Machine Model PHD2525
Application:
It is mainly used for efficient drilling of workpieces whose thickness is within the effective range, such as flanges, discs, rings, and plates. Through holes and blind holes can be drilled on elemental material parts and composite materials. The machining process of the machine tool is digitally controlled, and the operation is very convenient. It can realize automation, high precision, multi-variety and mass production.
Machine structure:
The machine bed is cast, mainly composed of worktable, movable gantry, movable sliding saddle, drilling and milling power head, automatic lubrication device, protective device, circulating cooling device, digital control system, electrical system, etc. Rolling hard rail pair support and guidance, precision lead screw pair drive, the machine tool has high positioning accuracy and repeat positioning accuracy.
1. Movable gantry:
The movable gantry is made of gray cast iron (HT250). The front side of the gantry is equipped with two ultra-high bearing capacity rolling linear guide pairs, a set of precision ball screws and a servo motor, so that the power head slide is used as the Y axis. When moving in the same direction, the drilling power head is installed on the power head slide plate. The gantry movement is realized by the rotation of the ball screw driven by the servo motor through the precision coupling.
2. Drilling power head:
The drilling power head adopts a dedicated servo spindle motor, and the geared synchronous belt decelerates to increase the torque to drive the precision spindle. The spindle adopts the first three rear two five-row Japanese angular contact bearings to achieve stepless speed change. The spindle is equipped with a pneumatic tool change system to enable tool replacement Fast and convenient, the feed is driven by a servo motor and a ball screw. The X and Y axes can be linked, using semi-closed loop control, which can realize linear and circular interpolation functions. The spindle end is a BT50 taper hole, equipped with high-speed rotary joint, and can use high-speed U-drilling center to discharge water.
3.Center water filtration system:
Equipped with a central water filtering system, which can effectively filter the impurities in the cutting coolant. The internal water spray system can prevent iron pins from being wound on the tool during processing, reduce tool wear, extend tool life, improve workpiece surface finish, and tool tip The high-pressure water outlet pin can well protect the surface of the workpiece, protect the high-speed rotary joint, prevent impurities from blocking the rotary joint, and improve the overall quality of the workpiece and improve work efficiency.
4.Automatic lubrication device and protective device:
Equipped with Taiwan's original volumetric partial pressure automatic lubrication device, it can automatically lubricate various motion pairs such as guide rails, screws, racks, etc., without dead angles, and ensure the service life of the machine tool. The X-axis and Y-axis of the machine tool are equipped with dust-proof protective covers, and splash-proof baffles are installed around the workbench.
