What is CNC cutting?

In the process of sheet metal processing, the cutting methods that are often used are manual cutting, semi-automatic cutting and numerical control cutting. Today we are going to talk about CNC cutting.

CNC cutting refers to the workpiece instruction (or program) used to control machine tools or equipment. it is a new control mode given in digital form, which is composed of numerical control system and mechanical framework. It is an organic combination of traditional processing technology and computer numerical control technology, computer-aided design and computer-aided manufacturing technology. Compared with traditional manual and semi-automatic cutting, it can effectively control and improve cutting quality and cutting efficiency.

Advantages and disadvantages of CNC cutting:

Advantages: effectively improve the utilization rate of steel and improve the work efficiency of cutting production preparation. The CNC cutting machine can effectively control and improve the cutting quality and cutting efficiency through the cutting technology, cutting technology and automatic control technology provided by the numerical control system, that is, the controller.

Disadvantages: because the cutting efficiency is higher and the nesting programming is more complex, if you do not use or do not use the optimized nesting programming software, the waste of steel will be more serious, resulting in faster cutting, more cutting, more waste.

Three CNC Cutting Methods

Laser Cutting Method

Cutting quality: excellent inclination and small area affected by heat. Basically no molten slag can achieve good to excellent fine cutting effect under the condition of the narrowest curvature.

Cost: due to the power and gas consumption, high maintenance cost and relatively low cutting speed when cutting thicker materials, the cost of a single operation is high.

Laser Cutting Method

Plasma Cutting Method

Cutting quality: excellent inclination, small area affected by heat, basically no slag, good to excellent fine cutting effect.

Cost: long service life of damageable parts, good production efficiency and excellent cutting quality, resulting in a lower cost of single operation than other technologies.

Plasma Cutting Method

Flame Cutting Method

Cutting quality: good inclination, large area affected by heat, large amount of molten slag, need to rework.

Cost: low production efficiency and rework, resulting in a higher cost of a single operation than plasma.
