one: Machinery Fittings processing, production process and process

Machinery Fittings processing production process is the raw material to finished. Mechanical manufacturing production process generally include:

1 parts processing machining, heat treatment, surface treatment, etc.

2 the products such as assembly, assembly and testing, inspection and paint etc.

3 production and technical preparation process design and special technology such as the design and manufacturing equipment, production planning, production material preparation, etc.

4 blank manufacturing such as casting, forging and pressing, etc.

5. Production services, such as raw materials, tools and supplies, out purchased parts, transportation, storage etc.

Mechanical processing and assembling process is mechanical manufacturing technology of the two main research content.

Second, the machining process

Machining process consists of one or several sequence of processes, and the process can be divided into several installation, location, and the sword.

(a) and work on

Generally speaking, the composition of any elements (processing surface, tools and machining continuity) change after work, namely, become another step. But below the circumstance that should be considered a work. In order to facilitate analysis and description of the content, process procedure could further step into work.

The machined surface (or refers to the connection assembly process (surface) and assembling or tools that under the condition of invariable continuous finish that part of the process. A procedure may include some work, also can only one step further. In Ⅰ installation of car seal face, big car outside the circle, drill φ 20 hole and chamfering etc, and surface processing due to the use of different tools, which constitute the four.

(2) process

Process is a or a group of workers in a work of one or several workpiece to finish by continuous that part of the process, the main contents and procedure according to work (or equipment) is whether that part of the changes and the complete process, whether continuous disc parts mini-batch production, the processing, When its batch production processing.

In the process of production change shape, size, relative location and nature, make the finished product or process of semi-finished products, called the process. Such as blank manufacturing, machining, heat treatment, the assembly to process.

In the process, if use machining method of producing objects directly change shape, size and surface quality, causes it to become qualified parts processing, called the machining process. Also, will be processed parts assembly into machine so as to meet the requirements of assembly precision and reserve technical performance of the process, called the assembly process
