Hi, everyone, my name is Jeff, an aftermarket engineer from AMOR. I would like to explain in detail what tools, functions, and applications of digital cutting machines are available through this article, and I hope to help you.
When many customers choose an oscillating knife cutting machine, they will encounter such a question – which processing tool should I choose? Some customers will choose according to their own processing materials, some customers want to have more powerful functions, and some customers want to achieve the fastest cutting speed… So, how to choose cutting tools? What are the differences between the various tools? Through this article, I will explain in detail the functions and applications of 10 common cutting tools in oscillating knife cutting machines, as well as the cooperation and use of various knives.
Why-AMOR-Digital-Cutting-Machine-Has-So-Many-Kinds-of-Cutting-Tools
First, we explain from the functional point of view of various tools. While there are many types of tools for digital cutters, we can summarize their functions into five types – cutting, grooving, creasing, punching, and marking.
Among them, the cutting function is the dominant function of the digital cutting machine, and other functions are selected and configured on this basis. The cutting function of the digital cutting machine can be divided into different cutting processes such as cutting through, half cutting, bevel cutting, multi-layer cutting, etc. This is why the digital cutting machine has so many types of cutting tools, among the tools of the digital cutting machine, the most types of cutting tools.
When you are choosing a digital cutting machine, the first thing you need to know is which cutting tool to choose. Cutting tools can be divided into three types – electric tools, air tools, and passive machining tools.
Common power tools can be divided into high-frequency oscillating cutting tools controlled by brushless DC motors and high-power oscillating cutting tools controlled by AC servo motors. The biggest difference between the two is that the high-frequency oscillating cutting tool is faster, and the high-power oscillating knife cutting machine is more suitable for cutting materials with high density, high hardness, and thickness.
oscillating cutting tools
Here, we talk about a misunderstanding that many customers will have – that the faster the tool is more capable, or the more powerful the tool, the faster the speed. This kind of understanding is wrong. For example, a high-frequency oscillating knife is more like a sharp knife. Through tens of thousands of high-frequency oscillations per minute, and its amplitude is only 1mm, it can quickly and perfectly cut materials. ; And the high-power oscillating knife cutter is more like an ax, you can imagine that if you use an ax to cut down a big tree, then you need to lift the ax high, and then drop it heavily, the same In order to complete the cutting of super-hard and super-thick materials, the high-power oscillating cutting tool not only increases its own power, but also increases the oscillation amplitude to 5mm. This is the difference between the two knives, one is better at speed and the other has more power.
If the material you are cutting is of medium density and the thickness is less than 10mm, then the high-frequency oscillating knife cutting machine is your best choice, such as leather, KT board, corrugated board, polyester fiber sound-absorbing board, gray board, silk circle, PU Sponge composite materials, etc…
If you are cutting materials with high hardness density, high hardness, or thickness greater than 20mm, then the high-power oscillating knife cutter is your best choice. Examples: asbestos gasket, graphite-reinforced gasket, EVA foam, teak deck, polyurethane, and other materials.
high-power oscillating knife cutting machine
Some customers may ask this question: Hello Jeff, if there is a material that is very soft, or very elastic, which cutting tool should I choose?
This is a really good question, and it is the constant questions from our customers that make us keep making progress.
In fact, there is a tool that is very suitable for the cutting of soft materials, such as a sponge, EPE foam, polyester fiber cotton, glass fiber cotton, and even multi-layer PU materials, that is Pneumatic Oscillating Knife Cutting Tool, referred to as POT, which uses 0.6MPA The compressed air is used as the power to drive the blade to oscillate rapidly with an amplitude of 8mm, thereby cutting the material. It is precisely the large-amplitude oscillation that reduces the stretching of the material during the cutting process and realizes the perfect cutting of soft materials.
Here, we want to talk about another misunderstanding: that each cutting tool has strict boundaries and cannot be replaced by each other. This is an incomplete concept. In fact, the functions of many pneumatic oscillating cutting tools have been replaced by more and more high-power electric oscillating tools. Why? Because both have large amplitude amplitudes, they are very similar in the mechanical structure, and both can be used to cut high-density, high-hardness, and large-thickness materials. At first, many factories recommended pneumatic oscillating cutting tools for everyone. Because it adopts pneumatic control, the vibration frequency can reach 8000 times per minute, while the high-power oscillating cutting tool adopts a servo motor, and its oscillation frequency is only 3000-4000 times per minute, so when cutting the same material, pneumatic oscillating cutters are faster.
However, the biggest disadvantage of the pneumatic oscillating knife cutting machine is that it requires compressed gas of not less than 0.6MPA, which requires the installation of a high-power air compressor. Generally, the power will not be lower than 11KW, so the processing cost per hour is very high. …
The needs of customers are the meaning of our continuous progress. In order to reduce the use cost of customers, we have increased the oscillation frequency of the high-power electric oscillating knife cutting machine to 6000-7000 times through the upgrading and transformation of the mechanical structure, so it also makes up for it. The problem of low processing speed, and because it adopts electric control, the power is more stable, it is more suitable for cutting some hard materials, and it also saves processing costs for customers.
Here, we’re going to talk about the third common misconception: one cutting tool can completely replace another cutting tool. The reason why we develop more tools according to the needs of customers is not to replace each other, but to make the two cooperate with each other to better meet the cutting of materials with different characteristics.
All the knowledge I have explained to you is just the experience I have summarized in my work for many years, but I am also constantly learning, and the technology of the oscillating knife cutting machine is constantly innovating and developing, so sometimes I often It will overturn the previous experience, and even it is difficult for us to determine which cutting tool is more suitable for a certain material, which requires us to conduct multiple cutting tests on the material according to our own experience, so as to obtain the correct answer.
In addition to the above three cutting tools, there is also a very important cutting tool, the driving wheel cutter cutting tool, which uses a motor to drive the blade to rotate rapidly, so as to realize the cutting of materials. This cutting tool is mainly aimed at cutting textile fabrics. Due to the strong power of motor drive, it can also be used for cutting artificial fur, plastic turf, and other coil materials. Its advantages are fast cutting speed, low requirements for material adsorption, and it is good at the fast cutting of large pieces. Its disadvantage is that it is not suitable for cutting complex shapes such as small circles.
The above four kinds of tools (high-frequency oscillating knife, high-power oscillating knife, pneumatic oscillating knife, driving wheel knife) are the four most important tools of digital cutting machine, all other tools exist as auxiliary processing, we also It is called a pair of knives, so how should these tools be selected?
If you want to cut thin materials with a thickness of less than 1.5mm and require extremely smooth cutting sections, then you can choose a drag knife, because it is a passive cutting tool without any power. Fast cutting for cutting, so the cutting section is very smooth. such as PVC film, etc.
If you want to achieve semi-through cutting of the material, then we recommend you to choose the kiss knife, which is also a passive cutting tool, coupled with a specially constructed blade, so it can achieve perfect semi-through cutting, often used for turning Posting and other advertising process processing…
If you want to bevel or groove the material, then we recommend you to choose a beveling tool, which has four cutting angles of 15°, 22.5°, 30°, and 45°, which can be adjusted arbitrarily by customers according to cutting requirements. Since this tool is also a passive cutting tool, it is suitable for medium-density materials and is not suitable for processing too hard or too soft materials.
If you need creases in the process of processing, then you can choose the indentation tool, and three different roller tools will be configured for you to meet the processing of materials of different thickness and hardness;
If you need to punch holes, then you can choose punching tools, we now have two kinds of punching tools, one is for quick punching for leather, fabric, and other coils, and the other is for punching sheets such as polyester fiberboard, so when you choose punching tools, be sure to tell us your processing materials;
If you need to mark and scribe on the surface of the material, then you can choose our marking system, which has two different marking methods, one is a brush system, the other is an inkjet system, a brush system The price of the inkjet system is cheap and suitable for some simple marking jobs, and the inkjet system is more expensive, but it is 10 times more efficient than the paintbrush and can be used for heavy-duty marking and scribing work.
In order to help customers better choose processing tools, we have summarized this, you can refer to the photo below, we hope to help you choose the right tool and create higher production value for you.
In the next article, we will explain to you what types of common tool combinations are there. Please pay attention to us, we will provide you with the most professional knowledge of digital cutting machines.
