The direct meaning is to say that it is computer digital control. It is a kind of processing technology commonly used in the manufacturing industry at present. It can also be said that it is the symbol of the current manufacturing industry. CNC machining center is mainly used to finish multi axis linkage processing easily. For example, the processing of curved surface is almost impossible if it is separated from CNC and processed by ordinary machine tools.

CNC machining center focuses on the processing of some careful spare parts, mainly used in automobile and motorcycle accessories, lighting lamps, automatic robots, mechanical hardware, aerospace military industry, electronic instruments, medical equipment, 3C digital, household appliances, communication mobile phone and other industries.

The materials processed by CNC machining center usually include ABS, PC, PE, POM, PP, PMMA, nylon, bakelite, silicone rubber, aluminum alloy, zinc alloy, magnesium alloy, titanium alloy, steel, copper, stainless steel, sheet metal and other raw materials.

The order process of CNC machining center is: 1. Order plan customization; 2. Disassembly and programming; 3. Material preparation; 4. CNC processing; 5. QC inspection; 6. Surface treatment; 7. QC quality inspection; 8. Delivery of molding products

In the process of processing, every step is very important. If one step is not in place due to carelessness in the process of processing, it is likely to directly affect the final effect of the product. Therefore, in the process of work, the operator must maintain a full state of mind, which is not only for their own good, but also has good results for the product, so if the CNC processing technology is not properly arranged, what problems will occur?

1. CNC machining process is too scattered

The reason for this problem lies in the fear of complexity (refers to the preparation time), simple programming, simple operation and processing, easy adjustment of tool setting by using a knife, and being used to ordinary processing. As a result, the product quality (position tolerance) is not easy to guarantee and the production efficiency can not be brought into full play. Therefore, CNC processing personnel and operators should be fully familiar with CNC machining knowledge, try more to master the relevant knowledge, as far as possible to use the method of process concentration for processing, more use, will naturally reflect its advantages. After two sets of equipment are used, the processing efficiency is greatly improved and the equipment quality is greatly improved.

1. CNC machining sequence is unreasonable

Some CNC processing operators consider some problems in preparation, and often arrange the processing sequence irrationally. NC machining is usually carried out according to the requirements of general machining process planning, such as coarse to fine (tool change), inside to outside, reasonable cutting parameters, so that the quality and efficiency can be improved

Large CNC lathe is a kind of high precision and high efficiency automatic machine tool. It adopts the method of machining parts and cutter displacement controlled by computer programming. Automatic lathe processing is an automatic machine tool with cam cutter. The machining is completely controlled by the cam. So what are the advantages of large CNC lathe and automatic lathe?

1。 The number of molds is greatly reduced, and complex molds are not needed to process parts with complex shapes. If you want to change the shape and size of a part, you only need to modify the part processing.

2。 The machining quality is stable, the machining precision is high and the repetition precision is high.

3。 Under the condition of multi variety and small batch production, the production efficiency is high, and the time of production preparation, machine tool adjustment and process inspection is reduced. And reduce the cutting time because the number of cuts is used.

4。 It can process complex profiles which are difficult to be processed by traditional processing methods, and even some parts that cannot be observed.

Advantages of automatic lathe processing:

1。 The processing speed is fast. In the process of automatic lathe processing, the tool carrier moves and processes at the same time, so that the processing speed of automatic lathe is 4-6 times faster than that of numerical control lathe.

2。 The processing cost is low. The price of automatic lathe equipment is lower than that of numerical control lathe, the processing speed is fast, and the processing cost is lower than that of numerical control lathe.

What is the significance of CNC processing of aluminum alloy profiles? The popular point is that CNC machining is the use of computer to program processing programs, such as cutting, tapping, tapping, counterbore, etc., basically relying on numerical control operation. Aluminum alloy CNC processing of alloy profiles can reduce product damage, so what are the advantages and disadvantages of CNC processing of aluminum alloy? Let’s take a look at it

The products with good use are easy to use and difficult to use. The advantage of CNC machining is that it can reduce the processing times. As long as the program is modified, complex aluminum profiles can be processed without complex tools. The processed aluminum profile has high precision and stable quality. Whether it is the traditional aluminum profile, the complex cross-section of different materials, or the parts with poor machining, CNC machining is operable.

Disadvantages of NC machining: processing equipment is more expensive, and the quality requirements of operators are relatively high.

CNC machining is CNC machine tool processing, that is, a set of processing program is compiled by computer, and the article is processed by digital milling machine. The same is true for CNC processing of aluminum profiles. Including cutting, drilling, tapping and so on, basically depends on CNC operation. CNC processing can reduce the damage rate of products, which is favored by aluminum profile manufacturers.

Advantages: ① greatly reduce the number of tooling, complex processing forms of parts do not need complex tooling. If we want to change the form and size of parts, we only need to modify the part processing program, which is applicable to the development and modification of new products.

② The machining quality is stable, the machining precision is high, and the repeated precision is high, which is suitable for the processing requirements of aircraft.

③ It can reduce the time of production planning, machine tool adjustment and process inspection, and reduce the cutting time due to the use of good cutting amount.

④ It can be used to machine the complex surface which is difficult to machine by conventional way, and even can process some parts which cannot be observed.

The disadvantage is that the processing equipment is relatively high, and the quality requirements of operators are high.

CNC is also called computer gong, cncch or CNC machine tool. In fact, it was introduced into the Pearl River Delta of mainland China. It is actually a CNC milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, a new type of machining technology is called CNC machining center. Its main work is to compile processing programs, that is, to convert the original manual work into computer programming. So what are the basic conditions for Dongguan CNC machining center maintenance?

1、 Basic conditions of maintenance personnel in CNC machining center

The quality of repair work depends on the personnel condition. It is necessary for repair workers to have the following basic conditions: a high sense of responsibility and outstanding professional ethics; a wide range of knowledge, grasp the basic knowledge of computer skills, analog and digital circuits, automatic control and motor drive, inspection skills and mechanical processing technology and a certain level of foreign language; through outstanding skills training, master the work of CNC, drive and PLC Professional principle, understand CNC programming and programming language; understand the structure, have experimental skills and strong ability to operate; grasp a variety of commonly used (especially on-site) testing instruments, appearance and various maintenance tools.

2、 The conditions of CNC machining center maintenance methods

Prepare common spare parts and accessories; get practical assistance or supply of micro electronic components at any time; repair necessary things, instruments, appearance, wiring and microcomputer. The best way is to have a small programming system or programmer to assist equipment debugging; complete materials, manuals, circuit diagrams, repair instructions (including CNC operation instructions), interface, adjustment and diagnosis, driver instructions, PLC instructions (including PLC user program list), component forms, etc.

CNC lathe processing suitable for which industries? The following brief introduction:

CNC lathe is used for processing: straight line cylinder, oblique line cylinder, arc and various threads.

CNC lathe, turning center, is a kind of high precision, high efficiency automatic machine tool. Equipped with multi station turret or power turret, the machine tool has ordinary processing performance. It can process linear cylinder, oblique line cylinder, circular arc and various kinds of thread, groove, worm and other complex workpieces. It has various compensation performance of linear interpolation and circular interpolation, and has carried forward the excellent economic effect in the batch production of complex parts.

Numerical control technology refers to the technology of controlling the behavior of one or more mechanical equipment with digital instructions composed of numbers, ink and symbols. Numerical control usually selects general or special computer to complete digital program control, so numerical control is also called computer numerical control, referred to as CNC, overseas is usually called CNC, rarely use the meaning of NC. It usually controls the position, angle, speed and other mechanical quantities and the switch value related to the mechanical energy flow direction. The occurrence of numerical control depends on the appearance of data carrier and binary mode data operation. In 1908, the perforated sheet metal exchange data carrier came out; at the end of the 19th century, the control system with paper as data carrier and auxiliary performance was created; in 1938, qingxiangnong carried out rapid data calculation and transmission at MIT, laying the foundation of modern computer, including the basic computer digital control system. Numerical control technology is closely integrated with machine tool control. In 1952, the first CNC machine tool came out, which became an epoch-making event in the history of the world’s machinery industry and promoted the development of automation.

Numerical control technology is also called computer numerical control technology, it is the use of computers to complete the digital program control technology. This technique uses a computer to control the movement track of the equipment and the operation sequence logic of the peripheral devices according to the control program stored in advance. Because the computer is used to replace the numerical control device composed of hardware logic circuit, the storage, processing, calculation, logic inference and other control functions of input operation instructions can be completed through computer software. The micro instructions generated by processing are transmitted to the servo drive device, driving motor or hydraulic actuator to start the equipment running.

Traditional machining is manual operation of ordinary machine tools. When machining, metal is cut by hand, and the accuracy of products is measured by eyes with calipers and other equipment. The modern industry has already used the machine tools controlled by computer Digitalization for homework. CNC machine tools may as well follow the program prepared by technical staff to automatically process any products and parts directly. This is what we call CNC machining. NC machining is not only used in any boundary of all mechanical processing, but also the development trend and important and necessary technical means of mold processing.

The above is the practical boundary of CNC lathe processing, I hope to help you.

The given machining route of CNC lathe refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the machining program. It includes the path of cutting and the path of non cutting empty stroke such as cutting in and cutting out. Today we will learn what advantages CNC processing has?

① A large number of tooling is reduced, and complex tooling is not needed to process parts with complex shapes. If you want to change the shape and size of parts, you only need to modify the part processing program, which is suitable for the development and modification of new products.

② The machining quality is stable, the machining precision is high, and the repetition precision is high, which can meet the processing requirements of aircraft.
