According to the principle of “first rough then fine”, for parts with high precision requirements, the machining accuracy is gradually improved by the sequence from coarse to fine. Dongguan high-speed computer gong processing this point for poor rigidity parts, especially can not be ignored. In order to solve such problems, the characteristics of titanium alloy materials, machining characteristics, tool data selection, milling processing characteristics, coolant and other aspects are analyzed to improve the one-time acceptance rate of titanium alloy parts, so as to control the product quality of the parts. In order to better control the product quality, computer gongs processing, Dongguan computer gongs processing, high-speed computer gongs processing, mechanical parts processing, computer gongs processing must first control the cutting parameters of non-standard equipment parts processing, and grasp the processing characteristics of materials.
Mechanical processing technology is to change the shape, size, relative position and nature of the production object on the basis of the process. CNC processing makes it a finished product or semi-finished product. It is a detailed description of each process. For example, as mentioned above, rough machining may include blank manufacturing, grinding, etc., and finishing may be divided into turning, fitter, milling machine, etc., and each step is just like this There must be detailed data, such as how much roughness and tolerance should be achieved.
The classification of machining is as follows:
Design datum: the datum used to determine the position of other points, lines and planes on the part drawing, which is called design datum.
Process datum: the datum used in the process of machining and assembling parts, which is called process datum. According to different uses, the process datum of Dongguan mould can be divided into assembly datum, measuring datum and locating datum.
(1) Assembly datum: the datum used to determine the position of parts in parts or products during assembly, which is called assembly datum.
(2) Measurement datum: the datum used to check the size and position of machined surface, which is called measuring datum.
(3) Positioning datum: the datum used for workpiece positioning during machining, which is called positioning datum. For the surface (or line, point) as the positioning reference, only the rough surface can be selected in the first process, such as computer gong processing, Dongguan computer gong processing, high-speed computer gong processing, mechanical parts processing, computer gong processing. This positioning surface is called rough datum. In the future, the machined surface can be used as the positioning reference, and this positioning surface is called precision reference.
