The laser cutting machine uses the laser beam emitted from the laser generator to focus on the laser beam irradiation condition of high power density through the optical path system. The laser heat is absorbed by the workpiece material and the temperature of the workpiece rises sharply. After reaching the boiling point, the material begins to vaporize and form Holes, accompanied by high-pressure airflow, move the relative position of the beam and the workpiece, and finally form a slit in the material. The process parameters (cutting speed, laser power, gas pressure, etc.) and movement trajectory during slitting are controlled by the CNC system, and the slag at the slit is blown off by the auxiliary gas with a certain pressure.
The laser cutting machine replaced the traditional mechanical cutter with an invisible beam. It has the advantages of high precision, fast cutting speed, not limited by cutting patterns, automatic material saving and material saving, smooth cutting, and low processing cost. It will gradually improve or replace traditional metal cutting equipment. The laser cutting machine is very good in cutting flexible materials, clean and smooth. However, laser machine maintenance is also more, the laser head will heat up after a long time, need water cooling. Because the laser is cut by high temperature, the yellow mark is often left after cutting the fabric. Another disadvantage is that the smell is very large and not environmentally friendly.
Laser cutter machine is mainly used for cutting wood, MDF, metal, plastic, acrylic and textile, leather, foam, sponge, paper and other flexible materials.
The digital cutting machine mainly uses the high-frequency vibration of the blade up and down to cut. This method changes the traditional cutting method that relies on the relative movement of the tool and the workpiece to complete the method. High-frequency vibration cutting is a pulsed intermittent cutting process, which can greatly reduce the cutting force, reduce frictional heat, improve the durability of the tool, reduce the roughness of the processed surface, and improve the tool life and the processing quality of the workpiece. In general, we put the process parameters, the motion path of the tool, the displacement, the cutting parameters (spindle rotation, feed, back-feeding, etc.) and auxiliary functions (tool change, spindle forward, reverse, cutting fluid on, off Etc.), according to the instruction code and program format specified by the CNC cutting system, write a processing program list, and then record the content of this program list on the control medium (such as perforated paper tape, magnetic tape, magnetic disk, bubble memory), and then enter In the CNC device of the CNC machine tool, the processed parts are processed automatically according to the pre-programmed processing program.
The digital cutting machine will vibrate up and down when cutting, tens of thousands of vibrations per minute, similar to the principle of a saw blade, but there is no serration, no powder will be produced, the vibrating knife can freely change the head, according to different materials, you can choose round Knife, half cutter, drag knife, bevel cutter, milling cutter, etc. The finished product cut by the vibrating knife is also clean and clean, the edges are smooth, and the size of the cut piece is accurate, odorless, more environmentally friendly, soft and hard materials are commonly eaten, and the leather cushion modification system is very good. Its cutting speed is twice that of a rotary knife and twice that of a laser. It is also the first choice for many companies now.
The digital cutting machine is mainly used for corrugated paper, car mats, car interiors, carton boxes, color boxes, soft PVC crystal pads, composite sealing ring materials, leather, leather, foam, shoe soles, cardboard, KT board, pearl cotton, sponge, composite materials, plush stationery and other flexible materials.
Digital cutting machine is a kinetic energy cutting machine newly developed in recent years, which is used to cut special-shaped patterns. Digital cutter machine tail blade contact cutting, ultra-high frequency vibrating knife cutting technology, which eliminates the disadvantages of manual cutting, such as irregularity, precision limitation, charring, and odor. The digital cutter machine has convenient output, high-speed cutting, high-speed indentation, rapid prototyping, knife-free mold, saving manpower and material resources, dataization, and improving production management of the enterprise.
Compared with the CNC laser cutter, the CNC digital cutter has the following technical advantages:
1. After cutting, the material edge will not blacken and carbonize.
2. It does not scorch when cutting thin materials.
3. It can cut copper and aluminum foil, conductive cloth, foam, Mylar, optical glue, backlight material and other materials that are difficult to process by laser.
4. There is no dazzling light when working, it will not harm the workers' body due to radiation, and it is quite safe.
5. Machine operating costs are cheaper than lasers.
6. It can be mass-produced in small batches.
The unique functions of the CNC digital cutter:
1. Full-cut and half-cut cutting can be done at once.
2. In addition, it can also be indented, or it can be completed at one time together with cutting.
3. Can also draw, you can use oil-based pen, ball-point pen, etc.
4. The smallest diameter of the cutting circle is 0.8mm.
5. The size of the cutting graphics is consistent with the effective cutting area of the cutting machine.
6. The cutting speed is adjustable from 1 to 60 cm/sec, and the maximum speed depends on the type of cutting material.
7. The cutting accuracy is guaranteed to be plus or minus 0.1mm.
8. The special-shaped processing of the material can be completed in one cut.
9. With repeated positioning function.
Digital cutting machine is a new type of processing technology. After long-term development, it completely replaces the traditional cutting method in a very short time, which not only provides convenient conditions for the development of the industry, but also allows the production of products. better quality.
