11.5T Weight CNC Plate Flange Drilling Machine Dedicated Servo Spindle Motor High-Speed Rotary Joint and Drill Center Outlet CNC Milling Machine for Precision Processing

High Speed CNC Plate Drilling and Milling Machine Model PHD2020

Mobile Saddle:

The mobile saddle is a precision cast iron structural component. It is equipped with two ultra-high load-bearing CNC linear rail slides, a set of precision ball screw assemblies, and a high-precision planetary reducer connected to a servo motor. This configuration balances the weight of the power head, reducing the load on the screw and extending its service life. The drilling power head is driven to move along the Z-axis, enabling actions such as rapid advance, working feed, rapid retraction, and stopping. It also features functions including automatic chip breaking, chip withdrawal, and pause.

Drilling head:

The drilling power head adopts a dedicated servo spindle motor, which drives a dedicated precision spindle through a toothed synchronous belt to increase torque. The spindle adopts a front four and rear two type six-row Japanese angular contact bearing to achieve stepless speed change. The spindle is equipped with a pneumatic tool change system to make tool replacement quick and convenient. The feed is driven by a servo motor and a ball screw. The X and Y axes can be linked and semi-closed loop control is adopted to realize linear and circular interpolation functions. The spindle end is a BT50 taper hole, equipped with a high-speed rotary joint, and can be processed with a high-speed U drill center outlet.

Transmission device:

It adopts high-precision design of guide rails and sliders imported from Taiwan, which runs smoothly and effectively improves the heavy-load capacity.

1. The X-axis and Z-axis respectively adopt two rolling linear guides as guide and load-bearing tracks for lateral and longitudinal movement. It can meet the technical requirements of high-speed drilling. The X-axis and Z-axis transmission adopts AC servo motors to drive the precision ball screw to rotate and realize linear motion.

2. There are two heavy-duty rolling linear guides on both sides of the Y-axis, one of which is a side-hanging structure, which together form the Y-axis sliding track. It can meet the high rigidity strength requirements of the gantry frame, and can also meet the technical advantages of small friction coefficient, fast moving speed, good vibration absorption performance and long service life. The X-axis transmission adopts dual servo motor synchronous drive technology, that is, one servo motor on each side, synchronously drives the ball screw to rotate, drives the gantry frame to move, and realizes CNC machining.

Automatic lubrication device and protective device:

This machine tool is equipped with a Taiwan-made volumetric partial pressure automatic lubrication device, which can automatically lubricate the guide rails, lead screws, racks and other moving pairs without any dead angles, ensuring the service life of the machine tool. The X-axis and Y-axis of the machine tool are equipped with dustproof protective covers, and waterproof splash shields are installed around the workbench.

Laser interferometer:

Each device is calibrated with the American API laser interferometer to accurately inspect and compensate for pitch error, backlash, positioning accuracy, repeated positioning accuracy, etc., to ensure the dynamic and static stability and processing accuracy of the machine. To ensure the 3D processing accuracy and circularity of the machine.
