There will be some problems that affect accuracy in the processing of hardware parts. So what are the factors that affect the accuracy of machining? Let’s take a look at it together: The original error of the process system: the geometric error of the process system, such as the machining principle error, the geometric accuracy of the machine tool, the manufacturing error of the tool and the ...
According to the precision CNC machining company, machining is a process in which machining machinery is used to change the shape or performance of the workpiece. According to the temperature state of the workpiece to be processed, it is divided into cold processing and hot processing.
Generally processing at room temperature, and does not cause chemical or phase changes of the workpiece, it is called cold processing. Generally, processing at higher or lower than normal temperature will cause the chemical or phase change of the workpiece, which is called thermal processing. Cold processing can be divided into cutting processing and pressure processing according to the difference in processing methods. Thermal processing commonly includes heat treatment, forging, casting and welding.
In addition, cold heat treatment is often used during assembly.
For example, during the assembly of bearings, the inner ring is often cooled in liquid nitrogen to shrink its size, and the outer ring is appropriately heated to enlarge its size, and then assembled together. The outer ring of the train wheel is also heated on the base body, and the firmness of the combination can be ensured when it is cooled (this method is still used in the transfer process of some parts).
According to the analysis of precision CNC machining companies, machining includes: filament power winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting , Precision welding, etc.
According to the introduction of precision CNC machining company, mechanical processing: broad-meaning mechanical processing refers to the process of manufacturing products by mechanical means; narrowly refers to the use of lathe (Lathe Machine), milling machine (Milling Machine), drilling machine (Driling Machine), and grinding machine ( Grinding Machine), stamping machines, die-casting machines and other special machinery and equipment to make parts.
