Innovative PXD2020 Series High-Speed Gantry CNC Plate Drilling Milling Machine

This  machine  is  gantry  mobile  CNC  high-speed  drilling  and  milling  machine.   It  is  mainly  used  for  drilling  and milling of flanges,  heat  exchangers,  tube  sheets,  slewing  supports  and  other  workpieces.   It  can  not  only  use carbide drill bits for high-speed drilling with internal cooling, but also High-speed steel twist drill bits can be used to  drill  holes with  external  cooling.   The  processing  process  is  numerically  controlled,  the  operation  is  very convenient, and it can realize automated, high-precision, and multi-variety mass production.



Application

The machine is mainly used for drilling and milling of steel structure,iron tower, bridge, mechanical processing and other industries, such as connecting plate and floor board,drilling and milling of tubes, baffles and flanges in industries such as boiler petrochemical, pressure vessel and so on; drilling holes, blind holes, step holes, chamfering and light milling.

Features

CNC control system Siemens 808D

The CNC system of the machine adopts a full set of Siemens 808D bus version control system, and is equipped with RS232 interface and LCD screen, drilling coordinates can realize CAD/CAM direct conversion, convenient programming, storage, display and communication, the operation interface has man-machine dialogue, error compensation, automatic alarm and other functions. The CNC operating system is installed on the right side of the gantry, which can be moved longitudinally with the gantry for easy operation. This machine is equipped with CAD drawing conversion software independently developed by our company, and manual programming is not required for drilling. The workpiece hole position can be input using the keyboard or CAD floppy disk and the processing program can be automatically generated. It has the function of previewing and rechecking the hole position before drilling, and is easy to operate.

Drilling head BT50

The main spindle of the power head adopts a precision spindle (high-speed internal cooling), the spindle taper hole is BT50, and has a butterfly spring automatic broaching mechanism. The air-hydraulic pressure cylinder loosens the knife, making it very convenient to replace the tool. It can be equipped with carbide internal coolant drill bits and high-speed steel twist drill bits, and has a spindle taper hole purging and cleaning function.

Fixture of workpiece

This model suitable for big flanges with less holes , can add chuck self centering for easy fix of flanges Integrated design of high-quality casting workbench and bed. Increased equipment rigidity. A number of transverse T-shaped grooves are processed on the workbench, as well as an automatic centering mechanism, on which the workpiece to be processed can be placed. After centering is completed. The workpiece can be pressed tightly with a pressing plate through the T-shaped slot.
