Different Machining Processes

CNC Machining:

General CNC machining usually refers to computer digitally controlled precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc.

1. In CNC lathe processing, the determination of the processing route generally follows the following principles.

① It should be able to ensure the accuracy and surface roughness of the processed workpiece.

② Make the processing route the shortest, reduce the empty travel time and improve the processing efficiency.

③ Simplify the workload of numerical calculation as much as possible and simplify the processing procedures.

④ For some programs that are used repeatedly, subprograms should be used [1].

2. CNC machining has the following advantages:

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

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

③The production efficiency is higher in the case of multiple varieties and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimal cutting amount.

④ It can process complex profiles that are difficult to process with conventional methods, and even process some unobservable parts.

The disadvantage of CNC machining is that the machine tool equipment is expensive and requires maintenance personnel to have a high level.

Mechanical Machining:

Refers to the process of changing the external dimensions or performance of the workpiece through a mechanical device. According to the difference

in processing methods, it can be divided into cutting processing and pressure processing.

1. Production process:

Refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and preservation of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, assembly and commissioning of products, painting and packaging.

The content of the production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize production and guide production, and regard the production process as a production system with input and output. In the production process, the process of changing the shape, size, position and nature of the production object to make it into a finished product or semi-finished product is called a process. It is the main part of the production process.

The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of the parts and the assembly process of the machine, and the other processes are called auxiliary Processes, such as transportation, storage, power supply, equipment maintenance, etc.

2. Process:

The main feature of a process is that it does not change the processing objects, equipment and operators, and the content of the process is that the continuous steps are completed under the conditions of unchanged processing surface, unchanged processing tools, and constant cutting amount. It is called the working stroke, and it is the process step completed by the processing tool once processing on the processing surface.

3. The production types are usually divided into three categories:

1. Single piece production: produce different structures and different sizes of products individually, and rarely repeat.

2. Mass production: The same products are manufactured in batches throughout the year. The manufacturing process has a certain degree of repeatability. Mass-produced parts.

3. Mass production: the manufacturing quantity of products is very large, and most work places are often repeated processing of a certain process of a certain part.

4. Original information:

(1) Product assembly drawings, parts drawings.

(2) Quality standards for product acceptance.

(3) The annual production program of the product.

(5) The production conditions of the manufacturing plant, including the specifications, performance and existing status of machine tool equipment and process equipment, the technical level of workers, the ability of the factory to make process equipment, and the power supply and gas supply capacity of the factory.

(6) Standards required for process specification design and process equipment design, various metal parts processing, sheet metal, box, metal structure, titanium alloy, high temperature alloy, non-metallic and other mechanical processing, mold design and manufacturing, wind tunnel combustion chamber design Manufacturing, non-standard equipment design and manufacturing, mold design and manufacturing.

The Advantages of Turning & Milling Compound Precision CNC Machining:

(1) Shorten the manufacturing process chain of products to improve production efficiency.

The CNC du turning and milling compound center can install a variety of special tools, new tool arrangement, reduce tool change time and improve processing efficiency. Turning and milling compound processing can achieve all or most of the processing procedures in one clamping, which greatly Shorten the product manufacturing process chain.

In this way, on the one hand, the production assistance time caused by the change of the installation card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling fixture are reduced, and the production efficiency can be significantly improved.

In the machining efficiency of the CNC turning and milling compound center, the new type CNC turning and milling compound center can be loaded with more special processing tools. The tool arrangement is completely different from the previous traditional CNC processing machinery, which can reduce the tool change time and improve the processing efficiency. , Turning and milling composite processing can achieve all or most of the processing procedures in one clamping, which greatly shortens the product manufacturing process chain.

(2) Reduce the number of clampings and improve the machining accuracy.

The reduction in the number of card installations avoids the accumulation of errors caused by the conversion of the positioning reference. At the same time, most of the current turning and milling processing equipment has online detection function, which can realize the in-situ detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product; the high-strength integrated bed design improves the difficulty The gravity processing ability of the cutting material;

the turning-milling machine tool is equipped with an automatic feeding device, which can realize automatic feeding to continue, and basically realize the assembly line operation of a single machine tool.

During turning and milling, the tool performs intermittent cutting, which can obtain relatively short cutting of the workpiece formed of any material, which is easy to automatically remove chips. And the intermittent chip can allow the knife to have sufficient time to cool, reduce the thermal deformation of the workpiece, and also increase the service life of the tool. Compared with traditional CNC machine tools, the turning speed of turning and milling is higher, the quality of the cut products is better, and the cutting force is reduced, the precision of thin-walled rods and slender rods is improved, and the quality of the workpiece is high.

Because the cutting speed can be decomposed into the rotational speed of the workpiece and the rotational speed of the tool, according to the mechanical characteristics, the rotational speed of the tool can be increased, and the rotational speed of the workpiece can be reduced to achieve the same processing effect.

This feature is especially suitable for the processing of large forging blanks Effective, because the reduction of the forging blank speed can eliminate the periodic changes of vibration or radial cutting force caused by the eccentricity of the workpiece, thereby ensuring the smooth cutting of the workpiece and reducing the errors in the machining of the workpiece.

When the turning and milling machine tool processes the workpiece, the low speed of the workpiece can effectively reduce the centrifugal force of the workpiece, avoid deformation of the workpiece, and help improve the machining accuracy of the part. The larger longitudinal feed can also be used to achieve precise cutting in turning and milling, and the surface roughness can also be effectively guaranteed.

The turning and milling composite machine tool can use different methods such as turning, milling, drilling, and boring to process the workpiece. Able to complete multi-face machining tasks with one clamping, ensuring machining accuracy.

We have installed robot arm for two injection molding machines….

Plastic Parts Injection Molding China

We have installed robot arm for two injection molding machines in March 2017, It can increase our production speed,suitable for big quantity plastic parts mass serial production.

Injection molding machine’s robot arm also called  injection manipulator,The structure of an injection manipulator consists of an executive system, a drive system, and a control system. The execution and drive system is designed to accomplish the normal function of the arm, and to drive the movement of the mechanical parts by pneumatic or motor, so as to achieve the function of fetching. With the deepening of the application of the manipulator, now insert inserts, cut products, glue openings and simple assembly.

Because the injection manipulator can greatly improve the productivity and reduce the production cost, the quality of the injection molding product can be stabilized and improved, and the loss caused by the operation error of the person can be avoided. Therefore, the role of injection molding manipulator in injection molding is becoming more and more important. At present, the domestic manipulator type is relatively simple, and mostly used for taking pieces. With the development of injection molding industry, more and more robots will be used in the process of feeding, mixing, automatic loading and unloading of molds, recycling of waste materials and so on, and will be developing in the direction of intelligence. Plastic occupies a very important position in our industry, livelihood and other materials, many materials have been replaced by plastic; plastic molding includes: injection molding, plastic molding, blow molding, extrusion molding, casting molding, injection molding is the most widely used. In the automotive, communications, electronics, electrical, home appliances, medical, cosmetics, daily necessities, office supplies and other industries are very popular. In the traditional injection molding process, from the earliest artificial mold molding, injection molding machine to mold molding pressure, evolved into today’s computer control in the forming process, the reaction progress not only in quality, product appearance, and forming efficiency. Injection molding competition, forming quality and efficiency between enterprises; forming quality and injection molding machine mold process itself performance, and the surrounding environment, the forming efficiency and accuracy, mold molding technology and production quantity; with the injection molding machine operators increasingly tight supply, the labor cost increases, the removal of mechanical injection molding machine the hand is also more and more widely used. The application of plastic forming automation is very common. The manipulator mainly displays the following uses in the process of application:
1. The manipulator takes out the product in the mold, replaces the person, turns the original semi-automatic production to the fully automated production;
2.The manipulator takes the product out of the mold, embedded components(label, metal insert, 2nd molding etc.);
3. Automatic packing after mechanical hand is taken out and automatic storage;
4. Automatic feeding system of raw material and waste material recycling system;
5. the whole factory production control system and so on;
Because of the different molding products, automation applications are also very complicated, because it can replace human inefficiency, guarantee the molding process, so it is more and more widely used. The manipulator of the injection molding machine is the most widely used in forming automation.
