What are the various processes of machining, what is the machining process?

Too much. Let me tell you a little bit about it.

After receiving the order, the process is arranged first, which requires a high technical foundation. Blanking, forging, heat treatment, machining, surface treatment. Wait a minute.

The important thing is machining, which is the gathering place of technology. There are turning, milling, planing, grinding, drilling, etc. Generally, the first article should be sent for inspection during mass production.

It is too much to ask which process to pay attention to, and it is too much to say. I'm a lathe, so I'll talk about it later.

The machining process is the process of manufacturing and processing the workpiece or parts, and the process of directly changing the shape, size and surface quality of the blank by using the method of machining to make it a part is called the machining process. For example, the processing process of an ordinary part is rough machining, finishing, assembly, inspection, packaging, which is a general process of processing.

Machining technology is to change the shape, size, relative position and nature of the production object on the basis of the process. To make it a finished or semi-finished product is a detailed description of each step, each process, such as roughing may include blank manufacturing, grinding, and so on. Finishing may be divided into turning, fitter, milling, and so on.

There is detailed data for each step, how much roughness has been reached, and what tolerances have been reached.

Machining process.

Machining process specification is one of the process documents that stipulate the machining process of parts, and operation methods, etc., which is a more reasonable process and operation method under specific production conditions. In accordance with the prescribed form written into a process document, after approval to guide production.

The machining process specification generally includes the process route of workpiece processing, the specific content of each process and the equipment and process equipment used, the inspection items and inspection methods of the workpiece, the amount of cutting, the time quota, etc.

It refers to the method of machining, in the prescribed orderThe whole process of turning a blank into a part.

Machining process.

1. It is the process of manufacturing and processing the workpiece or parts, and the process of directly changing the shape, size and surface quality of the blank by using the method of machining to make it a part is called the machining process.

2. On the basis of the process, change the shape, size, relative position and nature of the production object, etc., to make it a finished or semi-finished product, which is a detailed description of each step and each process, for example, as mentioned above, rough processing may include blank manufacturing, grinding, etc., and finishing may be divided into turning, fitter, and milling machine.

And so on, there needs to be detailed data for each step.

3. According to the number of products, equipment conditions and the quality of workers, technical personnel determine the process to be adopted, and write the relevant content into process documents, which are called process regulations.

Methods of machining and processing:

1. Cutting processing:

Including turning, milling, planing, grinding, broaching, drilling, reaming, reaming, grinding, honing, polishing, superfinishing and automatic technology composed of them, CNC technology.

Group technology, combined machine tools, assembly lines, automatic lines.

Features: The main processing method is cutting processing, because the precision of cutting is high. There are many cutting processes, many equipment required, and large investments.

2. Less and no chip processing

It can be divided into precision casting, pressure machining and pressure finishing, as well as precision welding and rapid prototyping.

3. Special machining:

Common special machining methods include EDM, electrolytic machining, ultrasonic machining, ion beam machining, and electromagnetic machining.

Features: It belongs to non-contact processing, which can overcome rigidity with softness, and the hardness of the tool can be lower than the hardness of the workpiece. There is also no significant mechanical force during machining. Does not rely on mechanical force and mechanical energy.

Instead, it uses electricity, light, and heat energy to remove materials, and the energy density is high. The cutting principle is not applicable in these machining and does not produce macroscopic chips. The processing energy is easy to control and convert, easy to automate, and the processing range is wide and adaptable.

The pro-machining production process is as follows: 1. After receiving the customer's drawings and workpieces, first check the size of the workpiece, confirm the material, and whether the technical requirements and shape tolerances of each size need to be customized with special tools, drills, reamers, tooling fixtures, etc. 2. According to the processing accuracy of the processed parts, determine the type of processing machine tool (four-meter gantry milling, CNC gantry milling) according to the number of batches.

3. Arrange the production management to sign the order and send it back to the customer, and after confirmation, arrange the production cycle and confirm the delivery date. 2. Machining should be strictly implemented<> the blank body to the factory, first check the drawings of each size step, blank hole, groove whether there is a machining allowance, deformation, cracks, pores, sand holes and other phenomena that affect the processing quality to meet the requirements. No processing is allowed.

2. According to the requirements of the drawings, the maximum plane of the job is the processing "benchmark". Note: Not necessarily the entire plane is fully visible.

Then use the datum plane to process the opposite steps, holes, and slots. At the same time of processing, it is necessary to consider the clamping of the next process, the calibration of the table position and the processing allowance of each size, and try not to repeat the processing of one surface for many times. For example:

End milling, side milling above, side, steps, slots, holes, and dots should be completed at one time. In the process of processing, it is necessary to learn to self-check the corresponding size, and more than five workpieces should be reported to the quality department for first inspection. 3。

When processing large workpieces to lift and flange, it should be strictly implemented<> protective measures must be taken (backing plates, tires, cushion blocks) to avoid workpiece collisions, scratches, and defects. 4. Insist on correcting the measuring value of the measuring tool every day (with measuring blocks, standard correction rods, ring gauges, angle gauges) to wipe the measuring tools and maintain the measurement accuracy of the measuring tools. 5. The use of knives should follow who uses them and who keeps them.

The principle of careful use of thick knives, fine knives, forming knives, and wheels should be used carefully. The forming tool should be kept by a special person, and if it is worn, it should be reported to the supervisor to apply for grinding repair in time. For tools that cannot be used, go to the warehouse to go through the trade-in procedures after being approved by the team leader or supervisor.

3. When milling, boring, drilling, and turning are connected to the previous process, first check whether each size is processed according to the requirements of the drawings. If there is a problem in the previous process, the team leader and supervisor should be notified in time to deal with it, and the follow-up processing process can be carried out only after correction. 2. Boring, drilling, and milling machines should be flexible, and they do not necessarily require drilling and tapping after a workpiece is processed.

For the machined surface without subsequent processing, all the processing contents of the machined surface of this process can be completed. 4. After the whole piece is processed, it should be cleaned of burrs, chamfers, chamfers, scrubbed, and sent to QC to check each size. 2. Use an air gun to blow clean the holes, steps, tooth holes, iron sky and other debris in the slot.

Coated with anti-rust oil, warehousing to external processing (heat treatment, grinding, blackening) 3. Notify the production management and arrange delivery. Hope mine can help you <>

Do you have any other questions?

From the analysis of the part drawing to the program inspection, the whole process of processing the sample. There are two ways to program CNC machine tools, "tool point" refers to the starting point of the tool's relative workpiece movement during CNC machining, and it is also the starting point of program operation, also known as "program origin".

The part program is a machining program written on the input medium, or it can be an input prepared for the computer, and the processing program is obtained after processing.

The process of manufacturing and processing a workpiece or part, using the method of machining, directly changing the shape, size and surface quality of the blank, etc., to make it a part is called machining process. For example, the processing process of an ordinary part is rough machining, finishing, assembly, inspection, packaging, which is a general process of processing.

The production process of mechanical products generally includes: 1Preparation of production and technology, such as process design and design and manufacture of special process equipment, preparation of production plan, preparation of production materials, etc.; 2.

Manufacture of blanks such as casting, forging, stamping, etc.; 3.Machining and cutting of parts, thermal concealment, surface treatment, etc.; 4.Product assembly such as **, assembly, commissioning inspection and painting, etc.; 5.

Production services such as raw materials, purchased parts and tools, transportation, storage, etc.; The process of changing the shape, size, relative position and nature of the production object in the production process to make it a finished or semi-finished product is called a process. For example, the manufacturing, machining, heat treatment, and assembly of blanks are all technological processes. In the process, if the shape, size and surface quality of the production object are directly changed by the method of machining, so that it becomes a qualified part of the stool hall process, it is called the machining process.

Similarly, the process of assembling the machined parts into a machine to achieve the required assembly accuracy and obtain predetermined technical properties is called the assembly process. Machining process and assembly process are the two main contents of mechanical manufacturing technology research.

Summary. 1. Auxiliary operation is marking, which is the operation of drawing the processing boundary on the blank or semi-finished workpiece according to the drawing. 2. Machinability: chiseling, sawing, filing, tapping, and threading.

Various operations such as drilling (reaming, reaming), scraping, and grinding. 3. Assembly operation is assembly, the process of assembling parts or components into the machine according to the technical requirements of the drawing. 4. Maintenance operation is maintenance, which is the operation of repairing, inspecting and repairing machinery and equipment in service.
