The CNC machining center is composed of mechanical equipment and a CNC system, and is suitable for high-efficiency automatic machine tools for processing complex parts. 

It concentrates the functions of milling, boring, drilling, tapping and thread cutting on one device, so that it has a variety of processing methods. 

Machine tool manufacturing is an important part of equipment manufacturing, and equipment manufacturing is the foundation of our country's economic construction. 

Therefore, in recent years, my country has increased policy support for machine tool manufacturing.

Sine Electric cooperates with CNC numerical control system, adopts EA180E series Ethercat bus control scheme, up to 100M communication rate, 

short synchronization cycle, simple wiring, quiet and stable operation, quick response, and accurate positioning.

The four-axis drilling, attacking and milling compound machining center is composed of the main shaft (spindle motor), 

X-axis, Y-axis, Z-axis and the workpiece rotation axis. One machine replaces the processing efficiency of three machining centers, 

and the tool change time is saved during the process. . It is suitable for medium and large batch processing of copper, zinc alloy, aluminum alloy, 

stainless steel, and steel parts. It can complete drilling, tapping, and milling processes in one clamping, and can be used for heavy cutting.

It is composed of controller, servo system, pneumatic system, sensors, etc.:

1. Controller: including HMI and CNC system, is the core of the whole set of equipment, mainly responsible for data calculation and processing, display of various states, and parameter setting;

2. Servo system: an important part of the whole scheme. Responsible for executing CNC instructions, completing corresponding actions quickly and accurately, 

and has high requirements for responsiveness and stability.

3. Pneumatic system: clamping and positioning of the workpiece, holding brake.

4. Sensor: origin position, limit, etc.

Topology diagram:

Ethercat bus communication, high communication rate, short synchronization cycle, simple wiring, no interference;

The parameter setting is simple, only need to set a few parameters;

Servo gain tuning is easy to use, just set the rigidity and inertia to adapt to different loads and working conditions;

High precision: repeated positioning accuracy is 0.008mm
