Laser cutting process more and more replaces the traditional mechanical cutting machine in the sheet metal processing industry. Laser cutting machine has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting saves materials, smooth incision, and low processing cost. It will gradually improve or replace the traditional mechanical cutting machine.  The mechanical part of the laser cutter head has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat-affected zone is small, the deformation of the plate is small, and the kerf is narrow ( 0.1mm~0.3mm); high processing precision, good repeatability, no damage to the material surface; the most important is its CNC programming function, can process any shape, and can cut the whole board with a large format without opening molds is economical and time-saving.


How to Choose?

1. First of all, you must figure out the production scope, processing materials and cutting thickness of your products, so as to determine the model and quantity of the machines to be purchased, and make a simple foundation for the later procurement work.

Laser cutting machine applications involve mobile phones, computers, sheet metal processing, metal processing, electronics, printing, packaging, leather, clothing, industrial fabrics, advertising, crafts, furniture, decoration, medical equipment and many other industries. The mainstream models on the market are 3015, 4020, 6020 that is, 3 meters by 1.5 meters and 4 meters by 2 meters, and 6 meters by 2 meters.  Generally, companies will provide a variety of models for customers to choose from, and laser cutting machine can also be customized.


2. Professionals conduct on-site simulation solutions or provide solutions, and can also take their own materials to the manufacturer for proofing.

1) Fine cutting kerf: the laser cutting kerf is generally 0.10mm-0.20mm;


2) Smooth cutting surface: Whether the cutting surface of laser cutting has burrs or not; generally speaking,  the laser cutting machine has a little burrs, which is mainly determined by the cutting thickness and the gas used. Generally, there are no burrs below 3mm. The gas is nitrogen for the best effect, followed by oxygen, and air for the worst effect. The fiber laser cutting machine has minimal or no burrs, the cutting surface is very smooth, and the speed is also very fast.


3) Look at the deformation of the material: the deformation of the material is very small.


4) The size of the power: For example, most factories cut metal sheets below 6mm, so there is no need to buy a high-power laser cutting machine. A 500W fiber laser cutting machine can meet the production needs. If the production volume is large, worry about the 500W efficiency It is not as good as a high-power laser cutting machine. The best choice is to buy two or more small and medium-power laser cutting machines, which will help manufacturers in controlling costs and improving efficiency.


5) The core part of laser cutting: whether the laser and laser head are imported or domestic. Imported lasers generally use more IPG, and domestic ones generally use Raycus. At the same time, other accessories for laser cutting must also be Pay attention, such as whether the motor is an imported servo motor, guide rail, bed, etc., because they affect the cutting accuracy of the machine to a certain extent. One thing to pay special attention to is the cooling system of the laser cutting machine - the cooling cabinet. Many companies directly use household air conditioners for cooling. In fact, everyone knows the effect, which is very bad. The best way is to use industrial air conditioners, which are dedicated to special machines. , to achieve the best results.


3. Any set of equipment will be damaged to varying degrees during use, so in terms of repairs after damage, whether the repairs are timely and the cost of repairs has become a problem that needs to be considered. Therefore, when purchasing, it is necessary to understand the after-sales service of the company through various channels, such as whether the maintenance fee is reasonable and so on.

Press brake is the most commonly used bending machine in the sheet metal processing factories. It is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press the steel plate into parts of various angles and shapes according to the process requirements.


The frame is mainly composed of left and right columns, worktables and beams. The left and right oil cylinders are fixed on the columns. The sliders are connected with the pistons of the cylinders and move up and down along the guide rails fixed on the columns. The lower die is fixed on the workbench, and the upper punch is installed on the lower end of the slider, the hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper die to close with the lower die to realize the bending of the sheet. The left and right columns, worktable and slider (hereinafter referred to as the three major parts) are the key parts of the bending machine, and the sum of the weight of the three major parts accounts for 70% to 80% of the total weight of a bending machine. Its strength and rigidity directly determine the running accuracy and service life of the machine tool, as well as the precision of the workpiece.

Hybrid Servo Press Brake


The servo hybrid press brake machine uses split double oil tanks, has an independent shock-proof buffer layer, and has a better mute effect. The position signals from the left and right sets of magnetic scales are used to control the left and right servo main motors through the computer. The left and right oil pumps are controlled respectively through forward rotation and rotational speed to generate the same flow and pressure, so that the left and right oil cylinders move synchronously and press up synchronously.

 

When the oil pump rotates forward, the slider goes down; when the oil pump rotates in reverse, the slider goes up. The left and right oil cylinders, oil pumps, servo motors, magnetic scales and computers form two closed-loop systems.

 

The servo motor rotates slightly during standby, quiet and energy-saving. When fast down, according to different speed requirements, the speed of the servo motor is different (high speed, low torque). During bending, the torque of the servo motor is different (high torque, low speed) according to the bending pressure. During the return trip, the speed of the servo motor is different (medium torque) according to different speed requirements.


Advantages:

1. Wuxi Shenchong oil-electric hybrid CNC system has the characteristics of high efficiency, energy saving, high precision, low noise, and environmental protection.

2. After actual testing, the repeated positioning accuracy of the slider is ±0.01mm, and the highest accuracy can reach 0.005mm.


3. Low noise is also one of its biggest features. During the use of the same model, the noise is basically controlled below 65 decibels, which greatly improves the superiority of the working environment.


4. Since there is almost no energy loss in the servo pump control system, the whole process will not cause a significant rise in oil temperature. When the ambient temperature is 38°C, the continuous working oil temperature shall not exceed 50°C. Thereby reducing the risk of oil leakage, higher stability, and improving the service life of all seals and cylinders in the hydraulic system.
