First, the choice of enterprises
With the rapid growth of the market demand for CNC cutting machines, many CNC cutting machine salesmen came out to set up companies. But they have no technical strength, production capacity, service and maintenance ability. They resell or assemble CNC cutting machines under the signboard of production enterprises. This kind of enterprise accounts for more than 80% in the CNC cutting machine industry. You may get a lower price from them, but there will be serious problems in the performance and subsequent service of the equipment. Therefore, Wuhan Jiabeide Technology suggests to you:
1. Find a well-known enterprise with production scale.
Wuhan Jiabeide Technology suggests that you must first verify the real situation of the enterprise. Choose some enterprises with a certain production history, a certain popularity, a considerable production scale and an annual production and sales volume of more than 200 sets to buy.
2. Look at the enterprise from the customer base.
Wuhan Jiabeide Technology believes that you can look at the customer cases it provides in this way: whether there are large enterprises, whether there are enterprises that buy repeatedly, and whether it can provide enterprises for you to visit on the spot.
If the enterprise has foreign sales, it is more trustworthy.
3. Look at the enterprise from the relevant certificates
Wuhan Jiabeide Technology believes that whether an enterprise has patent certificate, intellectual property certificate, ISO900 1 quality system certification certificate, CE certification certificate, etc. is also an important circumstantial evidence to confirm whether it has the production service capability and whether the production quality is guaranteed.
4. Field trip, seeing is believing
Wuhan Jiabeide Technology reminds you that there are a lot of false words in the publicity materials of many enterprises. Field trip is the most reliable way. See if it has a production base and a research and development and after-sales service team. This is the best way to eliminate your worries.
Second, the key points of NC cutting machine selection
Wuhan Jiabeide Technology suggests that you should focus on the following aspects when purchasing CNC cutting machines:
1. The system has high reliability.
Wuhan Jiabeide Technology believes that the working environment of NC blanking and cutting is extremely poor, and the reliability of the system is the most important because of the large dust, high temperature and serious interference during plasma cutting. This is also what Wuhan Jiabeide Technology pays special attention to.
2. Simple operation and maintenance
Wuhan Jiabeide Technology specially reminds you that the operating system should conform to the operating habits and technical level of blanking workers, so that ordinary blanking workers can operate and maintain easily without training or simple training. At the same time, the supplier should provide you with operation and maintenance multimedia, which is equivalent to giving you a master by your side for a long time, so that you can completely eliminate the worries of operator traffic. At this point, Wuhan Jiabeide Technology must do the best.
3. Better operation convenience.
For example, on the cutting torch, there are all kinds of necessary mobile counterpoint and control key operations. This is the unique function of Wuhan Jiabeide Technology.
4. Simple graphic input method
Can interface with various drawing software, can be loaded on U disk, and simple graphics can be programmed on site, which is simple and clear.
Third, the selection steps and methods of CNC cutting machine
Wuhan Jiabeide Technology believes that the selection of CNC cutting machine can be carried out according to the following steps.
1. Selection of width and size
The size of the layout should consider the specifications of the steel plate. Otherwise, it is not convenient to move the plate or equipment after cutting a part, and it is not conducive to saving materials.
2. Choice of structural form
There are usually three kinds of CNC cutting machines: cantilever, gantry and desktop.
Cantilever structure, convenient equipment movement and installation, no need to occupy a fixed factory building, and low equipment cost. However, due to the limitation of cantilever structure, the transverse cutting width is limited, and the beam rigidity is poor during high-speed cutting.
Gantry cutting machine, with good rigidity, can realize 3- 10m horizontal long span. However, equipment installation needs to occupy a special workshop area.
The desktop cutting machine is an integrated structure, which is convenient to move in place, but the cutting width is limited to some extent.
When permitted on the spot, priority should be given to gantry cutting machine. A large gantry CNC cutting machine can also set off the production strength and enhance the corporate image.
3. Selection and combination of cutting methods
The cutting methods of CNC cutting machine can be classified from different angles, and can also be combined in many ways.
1) flame cutting
Flame cutting, that is, cutting with oxygen and gas, is a traditional thermal cutting method, which is suitable for cutting medium-thick carbon steel plates, but not for cutting thin plates, stainless steel and non-ferrous metals below 5 mm.
2) plasma cutting
That is to say, cutting plates with plasma power supply is suitable for cutting carbon steel plates, stainless steel plates and non-ferrous metals, and the cutting speed is faster than that of flame. But it needs to be equipped with a special plasma power supply.
3) Straight bar cutting
Direct cutting refers to cutting a steel plate into multiple narrow strips with multiple cutting torches at the same time. In order to realize multi-purpose of one machine, it can be configured as dual-purpose numerical control flame and plasma cutting, numerical control and direct cutting, as well as dual-purpose plate and intersecting wire cutting.
4. Selection of cutting torch height adjustment mode
Whether flame cutting or plasma cutting, it is necessary to ensure that the height of the cutting nozzle from the steel plate is in the best state to obtain the best cutting effect and the longest service life of the cutting nozzle. There are several ways to adjust the height:
1) manual adjustment
Manual height adjustment is to adjust the height of cutting torch with handwheel. This height adjustment method is not suitable for CNC cutting machine.
2) Lift the electric button.
Adjust the height of the electric button by pressing the key on the operation panel. This height adjustment method is simple and reliable, but the operator must always pay attention to the height of the cutting nozzle from the steel plate and adjust it according to the estimation.
3) automatic height adjustment of capacitor
Capacitance adjustment, that is, using the principle of capacitance between two plates, uses the induction ring to detect the distance between the cutting torch and the steel plate. Capacitive automatic height adjustment is suitable for flame cutting. Adopting automatic height adjustment of capacitance, on the one hand, the cutting torch can automatically track the height change of the steel plate and always keep the height of the cutting nozzle from the steel plate unchanged; On the other hand, at the end of preheating, the cutting torch will be automatically raised before oxygen cutting, and then moved down after iron slag is splashed back, which can well reduce the blockage of the cutting nozzle and prolong the service life of the cutting nozzle.
4) Arc pressure automatic height adjustment
Automatic height adjustment of arc pressure, used for plasma cutting.
The plasma cutting speed is fast and the arc light is dazzling. If the operator observes the height of the cutting nozzle from the steel plate at any time and adjusts it, not only the reaction speed can't keep up, but also the eyes can't stand it. Therefore, plasma cutting must be accompanied by automatic arc pressure increase.
5. Cutting torch anti-collision device
In the process of cutting, it is inevitable that the steel plate or parts will tilt and the height adjustment will fail. The cutting torch is easily damaged at this time. Plasma cutting speed is fast, and the cutting cost of torch is high, so plasma cutting generally must be equipped with anti-collision device of torch.
6. Cutting torch orientation adjusting device
Sometimes it is desirable to have a certain groove on the cutting surface. For flame cutting, it is best to have a welding gun orientation adjustment device, which can adjust the welding gun to any angle.
