Today's machining industry, traditional machining equipment has been unable to meet the quality needs. CNC machine tool equipment replaces ordinary machine tools, and automatic processing equipment such as precision CNC machining and CNC lathe processing replaces traditional machine tools. The following will take you to understand the advantages of CNC machining machine tools and the order of precision mechanical parts processing.
What are the advantages of CNC machine tools?
In the process of machining mechanical parts, CNC machining machine tools have the following advantages:
1.CNC machining center has high precision and high processing quality.CNC machine tools are renowned for their exceptional precision and accuracy. They use computer-controlled movements and specialized software to perform tasks with minimal error margins. Unlike human operators, CNC machines consistently reproduce identical parts to exact specifications.
2.CNC machining parts can be multi-coordinate linkage, can process complex shape parts.CNC machine tools offer remarkable flexibility and versatility compared to traditional manual machines. With the ability to change tooling and adapt to various operations quickly, they are ideal for manufacturing complex and intricate components.
3.CNC machining process change, generally only need to change the numerical control program, can save production preparation time.CNC machine tools offer remarkable time-saving benefits. Traditional manual machining methods are time-consuming and labor-intensive, requiring extensive set-up and constant manual adjustments. In contrast, CNC machines can be easily programmed to perform complex operations accurately, greatly reducing production lead times.And CNC machining machine tool itself has high precision, large rigidity, can choose a favorable processing amount, high productivity (generally 3 to 5 times of ordinary machine tools).
4.CNC machining belongs to CNC machining equipment, high degree of automation, can reduce labor intensity.Although the initial investment in CNC machine tools may be higher than manual machines, they offer substantial long-term cost savings. These machines reduce labor costs since they require fewer operators for operation and supervision. Moreover, CNC machines minimize material wastage by executing precision cuts and reducing human errors, leading to significant material savings.
5.Increased Productivity and Efficiency.One of the most significant advantages of CNC machine tools is their ability to increase productivity and efficiency. These machines can operate around the clock, minimizing production downtime and maximizing output. Once programmed, they can perform complex tasks with minimal supervision, freeing up manpower for other critical areas of production.
CNC machine tools have ushered in a new era of production efficiency, accuracy, and cost-effectiveness. With precision, productivity, flexibility, cost savings, time-saving advantages, and the right skillset, businesses can harness the full potential of CNC machines and stay ahead in the competitive manufacturing industry.
Then the order of precision machinery parts processing is divided into what kinds？
Each processing method has its processing sequence. Our operators need to process in accordance with its processing order, but not disorderly, so that it will have a certain impact on the processed products, or quality problems. Precision machining is one of them, then the order of precision mechanical parts processing is divided into what kinds.
The arrangement of fine parts processing should be based on the structure and blank situation of the parts, as well as the needs of positioning clamping, and the focus is on the rigidity of the workpiece is not destroyed.
- The processing of the previous process can not affect the positioning and clamping of the next process, and the processing process of general fine parts in the middle of the cross should also be considered comprehensively;
- Stop the inner cavity processing sequence first, and then stop the outer shape processing process;
- The process of processing with the same positioning, clamping method or the same knife is best connected and stopped to reduce the number of repeated positioning, the number of tool changes and the number of moving platen. Shenzhen Machining;
- In the same device to stop multiple processes, should be arranged first to the workpiece rigid damage process.
Tool concentration sorting method: It is divided into processes according to the tool used, and all the parts that can be completed with the same tool are processed. In the second knife, the third knife to complete the other parts they can complete. This can reduce the number of tool changes, shorten the idle time, reduce unnecessary positioning errors.
Processing parts sorting method: On the processing content of a lot of parts, according to its structural characteristics will be processed local dividends several parts, such as internal shape, shape, surface or plane. Ordinary first processing plane, positioning surface, after processing holes; First processing simple geometric shapes, then processing complex geometric shapes; The parts with lower precision are processed first, and then the parts with higher precision requirements are processed.
In short, the current precision machinery parts processing technology is very advanced, high quality and high production efficiency.

Recycled plastics - such as from fishing nets or old bottles in car dashboards or carpets, would not affect safety or quality, Stuart Templar, director for sustainability at Volvo Cars, told Reuters.
We think this makes business sense, he said.
Many big companies are designing products that can be recycled after use to limit pollution. Volvos plan goes a step further by building ever more recycled materials into its production lines.
Volvo Cars is committed to minimising its global environmental footprint, Hkan Samuelsson, president and CEO of Volvo Cars, which is owned by Chinas Zhejiang Geely Holding Group Co Ltd, said in a statement.
Volvo said it was in talks with plastics producers to achieve its ambition that from 2025, at least 25 percent of the plastics used in every newly launched Volvo car will be made from recycled material.
Volvo sold 570,000 cars last year, with about five percent of plastics in its cars currently made from recycled materials.
Volvo unveiled a test model of its XC60 T8 plug-in hybrid SUV in Gothenburg, Sweden, that it said looks identical to the existing car except that some of its plastic parts were made from recycled materials.
The carpet, for instance, had fibres made from PET plastic bottles, old Volvo car seats were used in sound-absorbing material under the bonnet and fishing nets and ropes were used in the tunnel console - between the passenger and driver seats.
The United Nations welcomed Volvos plan. More than eight million tonnes of plastics end up in the oceans every year, threatening marine life from fish stocks to coral reefs.
As far as we are aware this is a first an attempt to source waste as a raw material for a new vehicle, Erik Solheim, head of the U.N. Environment Programme in Nairobi, told Reuters.
We need to see a situation in which plastic waste begins to have more value and the processes to transform it into something new will also advance, he said.
In 2017, Volvo said that it would electrify all new cars launched after 2019. Last month it said its aim was that fully electric cars would make up half of its global sales by 2025.
