Demand for wooden stairs and dining tables is also growing rapidly as people's spending levels rise. In this context, the manufacture of wooden stair handrails and table legs has become the bottleneck in the furniture industry, automatic CNC woodworking lathe came into being.

交流伺服在数控木工车床上的应用

 

First, CNC woodworking lathe features:

 1, the operating system is simple and friendly Chinese user interface, easy to operate.

 2, high precision, with a stable processing quality. Wood surface processing quality than ordinary woodworking lathe, subsequent grinding workload greatly reduced, can improve work efficiency.

 3, automatic tool change of the four-station electric knife holder.

 4, the processing of parts changes, generally only need to change the NC program, saving production preparation time.

 5, the machine itself, high precision, strong rigidity.

CNC woodworking lathe is a two-axis linkage, semi-closed-loop control. High rigidity of the structural design and shock absorption, to ensure high-precision machining. The servo drives and motors that control the X, Z axes of the feed axes require high dynamic response and precise positioning, making the tool post of the machine tool fast, stable and with high positioning accuracy.

The spindle of the machine must be a high-speed, high-rigidity spindles with quick start-stop characteristics, high efficiency and low noise design, so that parts can be processed with high efficiency, high precision and high speed means high production effectiveness.

Second, the system design:

CNC lathe system architecture

  (1) CNC control system

  (2) spindle system: spindle motor

  (3) X-axis drive system: 750W set

  (4) Y-axis drive system: 1KW set, for the servo axis X, Z servo performance requirements are mainly servo system has a high dynamic response and high positioning accuracy. Shinchikawa servo hardware platform based on DSP + FPGA + IPM, with high-speed frequency response, speed response bandwidth of 450HZ, living in the forefront of domestic servo; with resonance suppression, can be precisely tuned to eliminate vibration; control accuracy can reach 1 pulse, The maximum input frequency can reach 500Kpps, which are very good to ensure the required drive shaft requirements.

Third, sum up:

As an important function of CNC machine tools, the characteristics of servo system has been an important indicator of system performance. Power Chuan servo well meet the requirements of the numerical control industry for the domestic CNC industry made its own contribution.
