I. Control method

1.NC bending machine:

Digital control is adopted to control the bending angle, stroke and other parameters through pre-set programs.

Generally, only simple straight line bending can be achieved, and the bending processing capacity of complex shapes is limited.

2.CNC bending machine:

Computer digital control, with higher precision and flexibility.

It can realize multi-axis linkage, and can perform complex three-dimensional bending operations to meet the processing needs of various complex shapes of workpieces.

II. Convenience of operation

1.NC bending machine:

Programming is relatively simple, and processing parameters are usually set by manually entering digital instructions.

The operation interface is relatively simple and the functions are relatively simple.

2.CNC bending machine:

Equipped with an intuitive human-machine interface, the operation is more convenient and quick.

It can be programmed through graphical programming or importing CAD/CAM design files, which greatly improves programming efficiency.

III. Accuracy and stability

1.NC bending machine:

The accuracy is relatively low, and the repeat positioning accuracy is generally around ±0.1mm.

The stability is also slightly poor, and certain errors may occur after long-term operation.

2.CNC bending machine:

High accuracy, the repeat positioning accuracy can reach ±0.05mm or even higher.

The use of advanced control systems and high-precision sensors ensures the stability and reliability of the equipment.

IV. Processing efficiency

1.NC bending machine:

The processing speed is relatively slow, and the time for adjusting parameters and changing molds is long.

The efficiency for mass production is low.

2.CNC bending machine:

The processing speed is fast, and high-speed continuous bending can be achieved.

The degree of automation is high, and the parameters can be adjusted and the mold can be replaced automatically, which greatly improves the production efficiency.

V. Scope of application

1.NC bending machine:

Suitable for the processing of some simple-shaped workpieces, such as right-angle bending, U-shaped bending, etc.

It is more suitable for production occasions with low precision requirements and small batches.

2.CNC bending machine:

It can process workpieces of various complex shapes, such as arcs, cones, polygons, etc.

It is widely used in high-precision and large-scale production in the automotive, aerospace, electronics, electrical appliances and other industries.
