How Can A High-power CNC Engraving And Cutting Machine Choose The Right Speed To Cut High-quality Plates?

UTECH high-power CNC engraving and cutting machines are widely used in precision cutting and engraving of various materials such as metal, wood, and plastic. In order to ensure that the cutting effect meets high-quality standards, it is essential to choose the right speed. The correct speed can maximize cutting accuracy, reduce material waste, and improve processing efficiency. However, many operators often face the problem of how to choose the right speed when using CNC engraving and cutting machines. In this article, UTECH will explore the impact of speed on cutting quality and provide reasonable selection strategies to help operators optimize cutting effects and thus process more perfect workpieces.

1. The influence of speed on the cutting quality of CNC cutting machine: Why is it so important to choose the correct speed?

1.1 The direct influence of speed on the cutting quality of CNC engraving machine

When using a high-power CNC engraving and cutting machine, the choice of cutting speed directly affects the cutting quality. During the cutting process, the speed of the tool determines the contact frequency between the tool and the material, thereby affecting the cutting force and the quality of the cutting surface. Specifically, the influence of the change in speed on the cutting quality of high-power CNC engraving machine is mainly manifested in the following aspects:

Cutting surface smoothness: The appropriate speed can reduce the friction between the tool and the material, avoid excessive heat, and thus maintain the smoothness of the cutting surface. Too high or too low speed may cause burrs, burning or other surface defects on the cutting surface.

Cutting accuracy: Too high speed may cause increased vibration during cutting, thereby affecting cutting accuracy; too low speed may cause insufficient contact between the tool and the material, and high-precision cutting cannot be achieved.

Tool life: Inappropriate speed not only affects the cutting effect, but also may increase tool wear and shorten the tool life, thereby affecting production efficiency and processing costs.

1.2 Common problems caused by improper selection of CNC engraving machine speed

Too high speed: excessive heat is generated during cutting, which may cause the material surface to melt, uneven cuts, and even unnecessary burning. Too high speed will also increase vibration and reduce cutting accuracy.

Too low speed: If the speed is too low, the cutting efficiency of the tool will decrease, and it is easy to have slow cutting speed and long processing time, which will increase production costs; at the same time, the cutting surface will be rough and produce more burrs.

2. How to choose the appropriate speed according to the different materials cut by CNC machine tools?

2.1 Speed selection of metal materials

When cutting metal sheets, the selection of CNC machine tool speed needs to consider the hardness, thermal conductivity and other characteristics of the metal. For example:

Aluminum alloy: Aluminum alloy has good thermal conductivity and low hardness, so a higher speed needs to be selected to ensure that the heat during the cutting process is dissipated in time to avoid melting or deformation of the cutting surface.

Stainless steel: Stainless steel has a high hardness and is prone to generate large friction heat when cutting, so a lower speed should be selected and the feed speed should be increased to ensure a stable cutting effect and a smooth surface.

Carbon steel: The speed selection of carbon steel is relatively flexible, and the speed can usually be adjusted according to the cutting thickness. Thinner carbon steel can choose a higher speed, while thicker carbon steel needs to reduce the speed to improve the cutting quality.

2.2 Speed selection of wood and plastic

For soft materials such as wood and plastic, the selection of CNC machine tool speed is relatively wide, but it still needs to be adjusted according to the density and thickness of the material. The cutting speed of wood should be moderate. Too high a speed may cause the wood surface to burn, while too low a speed may affect the cutting efficiency. Generally, a moderate speed combined with a low feed rate can achieve a good cutting effect. The cutting speed of plastic materials is usually higher, especially for thin-walled plastics. A higher speed helps to prevent the plastic from melting during the cutting process and ensures the smoothness of the cut surface.

3. Other key factors affecting the selection of CNC engraving and cutting machine speed: materials, tools, equipment parameters

3.1 Hardness and thickness of materials

The hardness and thickness of the material have a direct impact on the selection of CNC engraving and cutting machine speed. Materials with higher hardness (such as stainless steel, titanium alloy, etc.) require lower speeds to reduce tool wear and excessive heat input. Thinner materials (such as thin steel plates, aluminum alloys, etc.) can choose higher speeds to improve processing efficiency. Thicker materials require lower speeds when cutting to ensure good heat distribution during cutting and avoid material deformation. For thinner materials, the speed can be increased to speed up processing.

3.2 Tool type and status

The material, coating and wear degree of the tool will affect the selection of cutting speed. Generally, high-performance coated tools can withstand higher speeds, while tools with severe wear need to reduce the speed to avoid a decrease in cutting quality. Carbide tools are suitable for high-speed cutting, while high-speed steel tools are suitable for medium and low speed cutting. However, as the tool wear increases, the cutting efficiency decreases and the cutting quality decreases. At this time, the speed should be appropriately reduced and a new tool should be replaced.

3.3 Speed range and stability of CNC equipment

Each CNC engraving and cutting machine has its specific maximum speed range. The operator should choose the speed according to the specifications and capabilities of the equipment to avoid exceeding the working range of the equipment. The stability of CNC equipment is also a factor that cannot be ignored. Choosing a CNC machine with high stability can ensure that good cutting quality can be maintained at a higher speed. UTECH provides high-quality CNC equipment, and the machine tool accessories are all from well-known brands, which are durable and have a long service life.

When a high-power CNC engraving and cutting machine cuts high-quality plates, choosing the right speed is a key factor in ensuring cutting effect and production efficiency. The correct speed can not only improve cutting quality, but also extend tool life and reduce material waste. In actual applications, operators should comprehensively consider the speed selection based on material type, thickness, tool condition and equipment parameters. Through reasonable speed adjustment, it is possible to improve production efficiency while ensuring cutting accuracy and meet different production needs.
