processing are two main types of manual processing and nc machining.
Manual processing is to point to by mechanical workers manual milling machine, lathe, drilling machine and the sawing machine and other mechanical equipment to implement various materials for processing.
Manual processing and suitable for small batch production, simple parts.
Nc machining (
Refers to the mechanical workers use numerical control equipment to carry on the processing, the CNC equipment including machining center, turning center, wire cutting equipment, thread cutting machine, etc.
At present, the vast majority of the machining shop all use nc machining technology.
Through programming, the workpiece coordinates in the cartesian coordinate system (
Converted into a programming language, the numerical control machine tool CNC controller by identifying and explain programming language to control the axis of nc machine tools, automatic removal of material, according to the requirement and finish machining workpiece is obtained.
CNC machining in a way that is straight artifacts, suitable for mass and complex shape parts.
Precision parts processing workshop can use CAD/CAM,
Computer aided design of computer aided manufacturing)
Automatic programming system for nc machine tools.
Parts geometry transform automatically from CAD system to the CAM system, mechanical workers in virtual display screen choose all kinds of processing methods.
When mechanical workers to choose a certain processing method, CAD/CAM system can automatically output CNC code, usually is refers to the G code, and enter the code into the controller of CNC machine tool for the actual machining operations.
Shenzhen precision parts processing procedure is specified parts machining process and operation method of process documentation, one of which is under the condition of concrete production, the reasonable technological process and operation method, according to the regulations in the form of a written into process file, used to direct production after approval.
Mechanical processing procedures generally include the following contents: workpiece machining process route and the specific content of each process and the equipment and process equipment, test items and test method of artifacts, cutting dosage, the time quota, etc.
Shenzhen precision parts processing technology is in the process, on the basis of change in the production of objects, properties, such as shape, size, the relative position and make it become the finished product or semi-finished products, is each step, a detailed description of each process, for example, it says, roughing may include blank manufacturing, polishing, etc. , finish machining may be divided into the car, fitter, milling machine, etc. , each step will have the detailed data, such as roughness to achieve how many, how much tolerance to achieve.
Technical personnel according to the product quantity, equipment condition and the quality of workers, etc. , determine the process of using, as the content of the related process files, this file is called process planning.
This is more targeted.
Every factory may not be the same, because the actual situation is different.
In general, the process is a platform, the processing technology is the detailed parameters of each step and process planning is a factory specific processing technology according to the actual situation.
Machining process include: five axis machining, ceramics, chemical, nc machining, edm, edm drilling, CNC titanium, urgent construction/scene processing, casting processing, grinding, fine processing (
Small pieces of processing)
, plastic processing, turning processing, thread processing, Swiss car processing, CNC machining, etc.
