When you want to use CNC oscillating cutter to solve various problems in production. You must be thinking: how to choose a machine with high quality and affordable price? However, since you are not a professional in the machinery industry and do not know enough mechanical knowledge, it is difficult to make a correct choice even if you have collected a lot of information.
This is indeed a difficult problem, but it is also a very important one.
Some customers choose cheap machines, the quality is very poor, which may bring unpredictable consequences to their factories, and even cause huge losses. Some customers are willing to choose the machine with high price, but when they receive the machine, they find that the configurations of the machine is very low, which makes them waste a lot of money.
Tell you a secret!
In fact, as a worker who has been engaged in the machinery industry for 11 years, when I face the choice of different customers, I will also encounter a problem: is it to insist on high-quality machines, or to reduce the production cost of machines? If we insist on making high-quality machines, then in the face of competition, some customers will give up choosing us because of the high price. If I choose to reduce the production cost of the machine, because of the low price, I will be selected by the customer, but there will be a lot of after-sales problems in the process of customer use, which will damage my brand.
Is it to do high quality or reduce production cost? It’s hard for me to choose!
Therefore, only let more customers master the method of distinguishing machine quality. Customers will not mistakenly choose a machine with low price or high price. They will choose a high-quality, affordable price CNC oscillating knife cutting machine by observing the details of the machine itself. Our factory can also insist on making high-quality, affordable price oscillating knife cutting machine, because customers are professional enough, low-quality machines will not be selected by customers.
So I think it is very meaningful for customers to learn how to distinguish the quality of machines. Through this article, even if you do not know mechanical equipment, as long as you observe the three details of the machine, you can easily identify the quality of an oscillating knife cutting machine.
TIP1: THE MACHINE BED STRUCTURE;
High quality machine bed is an important factor to ensure the continuous and stable operation of a CNC oscillating knife cutting machine. If the quality of the bed is poor, the machine will vibrate in the process of rapid cutting, resulting in poor cutting accuracy and unstable performance, especially when the machine is used for one year, deformation and platform collapse will occur.
If we put two oscillating knife cutting machines produced by different factories together, we can not judge the quality difference of the two oscillating knife cutting machines except for the differences in color and style.
When selecting the CNC oscillating knife cutting machine, you can ask the sales staff of the factory to provide you with a picture of the machine bed to observe the structure of the machine bed, the thickness and diameter of the pipe used. There are two types of common oscillating cutter bed: aluminum profile splicing type and integral steel pipe welding type. There is no doubt that the overall welding bed is heavy and stable.
SUGGESTION: When choosing the CNC oscillating knife cutting machine, must choose the whole welded bed.
The whole welded bed has great difference in bed structure and steel used. In order to reduce the production cost, some factories choose to use square steel pipes with small thickness and small diameter. There is no bearing support between the steel pipes, so the self weight is light, the working accuracy is poor for a long time, and the performance is unstable. However, the bed of our factory adheres to the use of 6 mm thick, 60 mm diameter steel pipe, with load-bearing support added in X, Y axis direction every 80-100 mm span. In the position where the rack and guide rail are installed, we use 60mm thick cast iron, and use CNC Gantry Machining Center for planing and milling. Our bed has the characteristics of heavy weight, good bearing capacity and high hardness, which ensures the accuracy and stability of high-speed operation of the oscillating cutter cutting machine. We promise that the machine bed will not deform for 10 years.
SUGGESTION: You should choose a machine bed with more self weight and reasonable structure.
TIP2: THE ACCESSORIES SELECTED FOR THE MACHINE;
Using high-quality accessories to produce high-quality machines, to ensure the continuous and stable work of the machine.
2.1 THE FIRST IS THE CHOICE OF MOTOR.
Motor is the core part to ensure the stability, high speed and continuous operation of the machine, just like the relationship between the engine and the car, so choosing a high-quality motor is the first step to produce a high-quality machine.
At present, the commonly used motors of CNC oscillating knife cutting machine are servo motors from China and servo motors imported from Japan. In order to reduce the production cost, some factories choose to use Chinese servo motor. Although the performance of Chinese servo motor has been greatly improved, Japanese servo motor has more advantages in motor stability and servo rigidity. The commonly used Japanese servo motor brands are Mitsubishi, Yaskawa, Matsushita and Fuji. All the driving motors of our company adopt Mitsubishi servo motor, which can meet the requirements of instant acceleration, fast cutting and lasting cutting of oscillating knife cutting machine. In addition, Mitsubishi Motor also has super adaptability and good heat dissipation performance, which can be used for continuous operation in extremely cold and high temperature environment.
SUGGESTION:If you have enough money, you must choose the servo motor imported from Japan
2.2. DRIVE AND TRANSMISSION MODE OF THE MACHINE.
Now, the common drive and transmission mode of CNC oscillating knife cutting machine can be divided into three types: single motor belt drive, single motor rack drive, double motor rack drive. Some customers may not understand what this means. In fact, it simply refers to the number of motors on the load-bearing shaft of the machine and the track that the cutting head moves when the machine is working.
First of all, understand the transmission mode of the CNC oscillating knife cutting machine. Because the maximum cutting speed of the CNC oscillating knife cutting machine is as high as 1500mm / s and the acceleration is 5000mm / s, so if you want to maintain such a high speed cutting for a long time, the rack drive is more appropriate, because the wear of the belt is very large due to long-time high-speed operation, and the customer needs to replace the belt, which is a very complex item Miscellaneous work. The wear resistance of rack is much higher than that of belt.
SUGGESTION: Choose the rack drive transmission mode of the machine and high quality grinding rack should be selected.
2.3 THE OSCILLATING CUTTER IS DIVIDED INTO SINGLE MOTOR DRIVE AND DOUBLE MOTOR DRIVE.
Single motor drive means that a motor is installed on one side of the x-axis of the machine, and then a transmission shaft is installed in the y-axis direction to ensure that both sides of the x-axis move at the same time. This installation method is more simple, but the cutting accuracy is poor, and with the working time of the machine, the cutting accuracy will become worse and worse. Therefore, our oscillating cutter adopts the mode of dual motor drive. We have installed rack and servo motor symmetrically on both sides of the machine beam to realize double tooth rack drive and double servo motor drive. The double side drive ensures the balance of the beam force, the synchronous operation of the beam, and the good precision of the continuous use of the machine.
SUGGESTION: You must choose dual motor drive, double rack drive, to ensure the accuracy of the machine for a long time.
- VACUUM ADSORPTION PLATFORM.
A complete vacuum adsorption platform is composed of four systems: aluminum honeycomb plate, felt table, high-power exhaust fan and platform detection system.
3.1 AT PRESENT, THERE ARE TWO TYPES OF HONEYCOMB ALUMINUM PLATE COMMONLY USED BY OSCILLATING KNIFE CUTTING MACHINE.
One is to select a complete 44.5mm thick honeycomb plate of aviation aluminum material. This honeycomb plate has good adsorption performance and high flatness, which can ensure the good cutting effect of the machine. My factory has always insisted on using this type of honeycomb plate.
The other is to select the ordinary aluminum plate with the thickness of only 10 mm, and then paste it on the PVC plate processed by milling cutter. The cost is low. However, because PVC will block the small holes of honeycomb, it will lead to poor adsorption performance, especially when cutting some small-sized cutting pieces, the material can not be firmly fixed.
SUGGESTION: You must choose a whole piece of aviation aluminum honeycomb panel, the thickness is 44.5mm;
3.2 THE COMMON VACUUM PUMP of oscillating knife cutting machine are divided into 5.5kW, 7.5kW and 9kw power. The higher the power, the better the adsorption effect of the machine is. Therefore, when you select the oscillating knife cutting machine, you must know the power of the suction pump.
Generally, the power of suction fan of 1600x2500mm oscillating knife cutting machine standard configuration will not be less than 7.5kW. When cutting some materials with good air permeability and thick thickness, the power of suction fan will be increased, which is generally increased to 9kw. However, our company will configure 2×5.5kw double vacuum pump for some special industries, such as acoustic panel cutting, gasket cutting and other industries, to ensure strong suction, overcome the problems of small suction of single vacuum adsorption system and the problem that partition adsorption can not meet the cross regional cutting of large-size cutting pieces. At the same time, in order to avoid the pressure caused by the vacuum adsorption system on the electrical environment when starting, we use batch start-up in the circuit design to ensure the smooth operation of the CNC oscillating knife cutting machine.
SUGGESTION: You should choose high-power vacuum pump as much as possible to ensure that the material is firmly fixed in the process of processing.
3.3. PLATFORM FLATNESS DETECTION SYSTEM is often ignored by some factories, but it is very important to extend the service life of the working platform and ensure good cutting effect. We not only provide each customer with a platform automatic detection system, but also design a “one key” start platform detection system. Customers only need to press the platform detection control button, and the machine will Automatic detection, customers do not need to carry out any installation.
SUGGESTION: Machine must be equipped with platform automatic detection system.
- IN ADDITION TO THE MOTOR, TRANSMISSION MODE AND WORKING PLATFORM, THERE ARE OTHER IMPORTANT CONFIGURATIONS:
4.1. The guide rail of the machine must choose theTAIWAN HWIN SQUARE LINEAR SQUARE RAIL, not the ordinary guide rail, because the guide rail of PMI adopts German high-quality steel, 45 ° ball design, good wear resistance, can reduce the friction force to 1 / 20-1 / 40 of the ordinary guide rail, and has extremely strong pressure resistance ability, which fully meets the working characteristics of high speed, high precision and high load of oscillating knife cutting machine.
4.2. PNEUMATIC ACTUATOR, control and processing components must also be of high quality, because the most vulnerable parts of a machine are such small parts. All of our machines are equipped with AIRTAC pneumatic components from Taiwan and FESTO pressing system from Germany, which have stable performance and long service life. The effective action of electrical components is up to 30 million times, which can well meet the requirements of punching and feeding functions of oscillating knife cutting machine, and ensure the good performance of long-term use of the machine.
4.3. THE REGULAR BRAND OF ELECTRICAL PARTS MUST BE SELECTED, otherwise it is easy to cause electrostatic interference and cause machine failure. The power switches, relays and other electrical components of our machines all adopt the French Schneider brand. Schneider, as a leading brand in the field of low-voltage electrical appliances, has the advantages of stable performance, high withstand voltage, low driving power, and strong current capacity.
Schneider Electric
4.4. THE MOTOR SIGNAL TRANSMISSION CABLE MUST BE HIGH FLEXIBLE CABLE, otherwise it is easy to cause the signal can not be transmitted normally and the machine will stop working. Our cables are made of German IGUS brand cables, which are strong, flexible and durable. It can overcome the damage of the cable caused by the high-frequency reciprocating operation of the oscillating knife cutter, and ensure the continuous and stable output of the motor signal.
TIP3:IN ADDITION TO THE MACHINE BED AND CONFIGURATION, BUT ALSO TO OBSERVE THE INSTALLATION PROCESS OF THE MACHINE
The quality of installation technology is the core factor to reflect the production quality of a machine, including mechanical installation, electrical design, etc. even if high-quality accessories are selected, if the installation is unreasonable, it is still unable to produce high-quality mechanical equipment. The most easily observed installation process is whether the wiring of the machine is scientific and clean.
So how to observe whether the wiring of an oscillating knife cutting machine is reasonable?
First of all, you should carefully observe the electrical box of the CNC oscillating knife cutting machine. You must reasonably arrange the circuit according to the voltage that the control board and electrical components can bear, so as to reduce the power load of the control board and ensure the rationality of the power supply for all parts of the machine. A qualified machine factory must ensure that the internal circuit of the oscillating cutter control cabinet is clean and orderly.
In addition, each cable should have a code to facilitate the later maintenance of the machine. This is a detail that many factories tend to ignore. However, all cables in our factory are equipped with codes. If there is a fault in the process of using the machine, you only need to find the corresponding coding line to replace it, which is very convenient.

Secondly, whether the cable of cutting tool part is arranged reasonably and orderly. In order to save working hours, many factories have unreasonable wiring here. The reserved cable is too long and exposed outside, which makes the cutting head look very chaotic.
Moreover, the layout of the air supply pipe must be reasonable, because the pneumatic oscillating knife cutting machine uses the gas to control the tool and machine feeding, so oscillating knife cutting machine needs to arrange the gas pipeline. In some factories, the machine design is not reasonable, and the reasonable arrangement of the air pipe is not considered, so that the air pipe is exposed outside the machine disorderly.
No matter the cable or gas pipe, our factory insists on proper length, scientific configuration, neat lines, hidden layout as far as possible, and keep the appearance of the equipment clean and tidy.
Even if you don’t know machinery, you can easily identify the quality of an oscillating knife cutting machine by observing the bed, configuration and installation process of the machine. You can choose a high-quality oscillating knife cutting machine at reasonable cost.
Have you learned it? As a staff member who has been engaged in the machinery industry for 11 years, I will share more knowledge about how to distinguish the quality of machines for you, and help you make more wise choices. Of course, AMOR as a professional CNC knife cutting machine manufacturer, will always insist on producing high-quality machines to help more factories realize intelligent production.
