Multifunction CNC Plate Cutting And Drilling Machine With Disc Tool Changer

Multifunction High Speed CNC Plate Drilling and Milling Machine with Disc Tool Changer

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.Laser interferometer:

The laser interferometer is used to calibrate, and accurately check and compensate the pitch error, backlash, positioning accuracy, repeat positioning accuracy, etc., to ensure the dynamic, static stability and processing accuracy of the machine. Ballbar inspection Each machine uses a British RENISHAW company ballbar to calibrate the true circle accuracy and machine geometric accuracy, and perform circular cutting experiments at the same time to ensure the machine's 3D machining accuracy and circle accuracy.
