How To Choose A Fiber Laser Cutting Machine?

First of all, we must consider the scope of our business: which metal material will we use? What is the thickness of the metal material? What is the size of our metal material? And factors like that. Then select the laser power of the equipment and the size of the worktable. At present, the power of laser cutting machines on the market is between 500W-12000W, and the overall size of the worktable can be customized according to customer needs.

Some important parts of the laser cutting machine will affect the overall performance of the machine, so you should also pay attention to this when choosing and purchasing. Fiber laser sources, laser cutting heads, servo motors, guide rails, coolers, and other parts directly affect the cutting speed and accuracy of the laser cutting machine, so you need to pay attention. If they all meet your needs, it will be a good choice.

• Choose the right laser power according to the cutting ability

The manufacturer should know exactly what material he will cut and its maximum thickness.

1) Please note that the cutting range of the laser source: the maximum limit thickness, which is only used to make simple patterns. The thickness of mass production means that it can be laser cut into whole sheets and processed in large quantities.
2) The high-power laser light source has high cutting performance for thick stainless steel and high-reflectivity materials such as copper/brass/aluminum. When 3000-12000w laser cuts stainless steel, the cutting ability of different thicknesses is similar.
3) If the manufacturer needs to cut materials with high reflectivities, such as copper, brass, aluminum, etc., it is necessary and recommended to choose a higher power laser.
4) Choose the brand of laser light source according to the budget.

• Cutting table size options

The standard workbench is 3015, 3000 * 1500mm, which can meet the most common steel plates of 1220 * 2440mm. Ordinary thin steel width 500-1500mm

If you need to cut larger slices, the laser table should be 2000 * 4000mm, 2000 * 6000, or 2500 * 6000mm.

• The core part of the laser cutting machine

Some important parts of the laser cutting machine also need to be paid attention to when buying. In particular, the laser generator, laser cutting head, servo motor, guide rail, water tank, etc. must be clearly defined as domestic or imported. These components directly affect the cutting speed and accuracy of the laser cutting machine. Many domestic manufacturers use domestic counterfeit parts to deceive customers.

• Equipment quality and stability in use are also important indicators.

Now that the product development cycle is short, the update is faster and faster, there are more product types, more prototype trial production, more mass production, how to maintain quality and quantity to complete customer orders, maintain corporate reputation, and enhance corporate competitiveness. The arduous task facing each operator, Therefore, purchasing stable processing equipment is the prerequisite and basis. Trying to choose a market with a high market share, perfect after-sales service system, after-sales service outlets, and long-term market testing, not only because of low prices, low quality, and no after-sales service Low-cost products will have a huge impact on the company’s production.

• Cutting speed selection

The cutting speed of the laser cutting machine is selected according to the thickness of the cut sheet, and different cutting speeds will have a great impact on the quality of the laser cutting machine. Choosing the right cutting speed can not only improve the efficiency of the laser cutting machine but also obtain good cutting quality. This is the effect of different cutting speeds on cutting quality:

The effect of too fast laser cutting feed speed on cutting quality

• It may not cause cuts and sparks will fall off.
• Certain areas can be removed, but certain areas cannot be removed.
• Causes the entire cut part to thicken, but there is no fusible generation.
• The cutting feed speed is too fast, resulting in the inability to cut the printing plate in time, the cutting part shows diagonal lines, and the lower part produces fusion stains.

The effect of too slow laser cutting feed speed on cutting quality

• Causes the cutting board to melt excessively and the cut part is rough.
• The slits will be widened accordingly, causing the entire area to melt into smaller rounded or sharp corners, failing to obtain the desired cutting effect.
• The cutting efficiency is low, which affects the production capacity.
• Appropriate cutting feed speed selection: the feed speed can be determined from the cutting sparks: generally cutting sparks are scattered from top to bottom, if the sparks are inclined, the feed speed is too fast; if the sparks do not disperse and decrease, they will condense together, The feed speed is too slow. At an appropriate cutting speed, the cutting surface shows smoother lines, and the lower half of the board does not fuse.

• The initial selection of laser cutting machine manufacturers

After determining the demand, we must go to the market or go to the colleague who bought the laser cutting machine to understand the performance and basic parameters of the machine. Then select a few strong, price-competitive manufacturers for communication and proofing in the early stage. If the sample can meet your requirements, we can go to the manufacturer to check the price of the machine, the training of the machine, the payment method, etc. at a later stage.
