3. The advantages of using CNC technology

The use of CNC laser technology in metal cutting processing has many important benefits. Here are some advantages of using CNC laser technology:

• High precision: CNC laser technology allows metal cutting with very high precision. The laser is capable of concentrating energy on a very small location, which cuts parts with great sharpness and accuracy.
• Speed and performance: CNC laser cutting machines are capable of performing cutting processes quickly. With its fast cutting speed and fast transition time between jobs, CNC laser cutting machines can increase production efficiency.
• Product diversification: CNC laser cutting machines are flexible and can cut various types of metals such as stainless steel, aluminum, copper, and many other alloys. This allows for the production of diverse and flexible products according to customer requirements.
• Material saving: CNC laser technology can optimize the cutting process to reduce material waste. By using intelligent control software, the CNC laser cutting machine can cut according to the optimal design pattern and arrange parts on the material sheet to save raw materials.
• Non-contact materials: CNC laser cutting machines use non-contact laser technology, which helps avoid wear or damage to the cutter. No material contact extends cutting tool life and reduces maintenance costs.
• Complex machining capabilities: CNC laser technology allows cutting complex shapes, square holes, circular holes, grooves and cutting slots, cutting to custom shapes and depending on the precise coordination of the machine and control software.
• Save time and labor: CNC laser cutting saves time and labor by automating the cutting process. The operator only needs to set the cutting parameters and program the machine, then the machine will perform the cutting process automatically and continuously. This minimizes intervention and manual work, which saves time and labor energy.
• Cost savings: CNC laser cutting machines can cut a large number of parts from material sheets, minimizing waste and optimizing material utilization. This saves raw material costs and increases competitiveness in production.

4. How has CNC machining changed the mechanical industry?

Time is an important factor in business operations. Applying CNC machine metalworking technology brings significant time benefits. The process of creating individual positions becomes significantly faster thanks to the automation and precision of this technology. CNC machines also increase processing speed and repeatability, reduce start-up time and execute simple machining programs.

Besides, using CNC technology also helps to reduce the size of the machine yard, while ensuring high quality for the final product. Now, a machine can perform a variety of positions, which optimizes resource utilization and saves space.

However, along with the obvious benefits of CNC technology and CNC machining, there are also some disadvantages. High cost is one of the drawbacks of this technology, making it possible for only large and developed companies to invest in CNC systems.

Another limitation is the requirement of professional knowledge of employees related to programming. To implement CNC technology effectively, employees need to master the knowledge of programming and controlling CNC machines, which requires periodic training and knowledge updates.

Despite certain disadvantages, the use of CNC laser technology is still the best option that brings great benefits in the mechanical industry, from increasing productivity and precision to saving time and resources.

5. What products is CNC mechanical processing used to produce?

CNC machining is used to manufacture a wide range of products in the mechanical industry. Here are some examples of products that are commonly machined using CNC technology:

• Machinery details: Shafts, gears, bearings, fasteners and other moving parts.
• Automotive auxiliary industry: automotive components such as brake discs, engine parts, suspension, valves and exhaust pipes.
• Aeronautical parts: Aircraft wings, chassis, engine kits and other structural parts.
• Medical equipment: Surgical instruments, endoscopic frames, X-ray machine parts, and other basic parts of medical equipment.
• Electronics industry: Electronic boards, containers, fasteners and other components in the electronics industry.
• Metal cutting tools: Milling cutters, turning knives, drills and other tools used in the metalworking process.
• Household products and appliances: Cooking appliances, household utensils, bathtubs, fans and other appliances.

These are just some common examples, and the applications of CNC machining are very diverse. This technology can be applied in almost all areas of mechanical manufacturing to create accurate, complex and high-quality products.
