Because of the different cutting materials, the choice of knives is also different. I have received a lot of such information before, asking us whether we can cut their materials, what kind of cutting tools should we choose, and many other questions. Today, I want to use this article to discuss in detail Introduce the tools, functions and applications of CNC cutting machines, I hope to help you solve half of the problems!
After our understanding, some customers will choose according to their own processing materials, some customers want more powerful functions, and some customers want to achieve the fastest cutting speed... So, how to choose a tool? What is the difference between the various tools? Through this article, I will explain in detail the functions and applications of 10 commonly used knives in oscillating knife cutting machines, as well as the coordination and use of various knives.
First, from the functional point of view of various tools, although there are many types of digital cutters, we can summarize their functions into five types - cutting, grooving, creasing, punching and marking.
What customers need to understand is that cutting is the dominant function of the digital cutting machine, other functions are selected and equipped on the basis of cutting, and cutting can be divided into different cutting processes such as full cutting, half cutting, and multi-layer cutting. This is why there are so many types of tools for CNC cutting machines.
When you choose a digital cutting machine, the first thing you need to know is which cutting tool to choose. There are mainly three types of cutting tools: vibrating knife, pneumatic knife and milling cutter.
Common vibrating knives include ordinary vibrating knives, imported motor vibrating knives, high-power vibrating knives and 5mm servo vibrating knives. Ordinary vibrating knives cut faster, and high-power vibrating knives are more suitable for cutting high-density, high-hardness, and high-thickness materials.
Here I want to tell you about the mistakes that are easy to make. The faster the tool, the more powerful the function, or the more powerful the tool, the faster the speed. This understanding is wrong. The vibrating knife is more like a sharp knife. Through tens of thousands of high-frequency oscillations per minute, with an amplitude of only 1mm, the material can be cut quickly and perfectly. And the high-power swing knife cutter is more like an axe, imagine that if you chop down a big tree with an axe, then you need to raise the axe high, and then put it down heavily, also in order to complete the super-hard super For the cutting of thick materials, the high-power oscillating tool not only increases its own power, but also increases the oscillating range to 5mm. This is the difference between two knives, one is faster and the other is more powerful.
If the material you want to cut is medium density and the thickness is less than 10mm, then the vibrating 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 material with high hardness density, high hardness or thickness greater than 20mm, then the high power swing knife cutter is the best choice for you. Examples: Asbestos gaskets, graphite reinforced gaskets, EVA foam, teak decks, polyurethane and other materials.
Some time ago, a customer asked us, if there is a material that is very soft, or very elastic, which knife should I choose?
That's a really good question, and it's the constant questions our customers have that keep us moving forward.
In fact, there is a tool that is very suitable for cutting soft materials, such as sponge, EPE foam, polyester cotton, glass fiber cotton, and even multi-layer PU materials. Powered by the drive blade, it oscillates rapidly in 8mm amplitudes, thereby cutting the material. It is the large-amplitude oscillations that reduce the stretching of the material during cutting, enabling perfect cutting of soft materials.
Each tool has strict boundaries and cannot be substituted for each other. In fact, many of the functions of pneumatic oscillating tools have been replaced by more and more high-power electric oscillating tools. Why? Because both of them have large amplitudes, they are very similar in mechanical structure, and both can be used to cut high-density, high-hardness, and large-thickness materials. At the beginning, many factories recommended pneumatic oscillating tools to everyone. Due to the use of pneumatic control, the vibration frequency can reach 8,000 times per minute, while the high-power oscillating tool uses a servo motor, and its vibration frequency is only 3,000-4,000 times per minute, so when cutting the same material, the pneumatic oscillating tool is faster. But the biggest disadvantage of the pneumatic oscillating knife cutting machine is that it requires a compressed gas of not less than 0.75MPA, and a high-power air compressor needs to be installed. Generally, the power will not be lower than 11KW, so the processing cost per hour is very high.
The reason why we have developed so many knives is not to replace each other, but to cooperate with each other to better meet the cutting of materials with different characteristics.
In addition to the types of knives mentioned above, there is also a type of knives called circular knives, which use a motor to drive the blade to rotate rapidly to achieve cutting materials. This cutting tool is mainly used for cutting textile fabrics. Due to the strong driving power of the motor, it can also be used for cutting artificial fur, plastic turf and other coils. Its advantages are fast cutting speed, low requirements for material adsorption, and good at fast cutting of large pieces. Its disadvantage is that it is not suitable for cutting complex shapes such as small circles.
In order to help customers better choose processing tools, we have summarized this, you can refer to the figure below, hoping to help you choose the right tool and create higher production value for you.
