Custom Precision Brass CNC Machining Parts

CNC machining process features CNC machining parts steps

CNC machining technology also follows the cutting rules of machining, and the processing technology of ordinary machine tools is roughly the same. Because it is the computer control technology applied in the mechanical processing of an automatic processing, so it has the characteristics of high processing efficiency, high precision, processing technology has its own unique, the process is more complex, the work step arrangement is more detailed and thorough.

CNC machining technology includes the selection of cutting tool, the determination of cutting parameters and the design of cutting process route. CNC machining technology is the foundation and core of numerical control programming, only reasonable technology, can make high efficiency and high quality numerical control program. The criteria for measuring the quality of a NC program are: the minimum processing time, the minimum tool loss and the best result of the workpiece.

CNC machining process is generally divided into rough machining, rough Angle machining, semi-finishing machining and finishing machining.

The programming of CNC

CNC programming is the whole process from parts drawing to obtaining NC machining procedures. The main task of the tool is to calculate the tool point in machining, the tool point is generally taken as the intersection of the tool axis and the tool surface, and the tool axis vector is also given in multi-axis machining.

CNC machine tool is according to the requirements of the workpiece pattern and processing process, the movement of the tool and each part, speed and action sequence, spindle speed, spindle rotation direction, tool head clamping, tool head loosening and cooling operation, in the form of the specified numerical control code into a single program, input into the machine tool special computer. Then, the CNC system according to the input instructions for compilation, calculation and logic processing, output a variety of signals and instructions, control each part according to the specified displacement and sequential action.

CNC machining center can process what parts parts

1, CNC machining center processing is generally processed those multi-type small and medium-sized batch parts. With the gradual decline of the manufacturing cost of CNC machining center, at present, whether domestic or foreign, the processing of large quantities of parts has also appeared. Processing small batch and single production, if can shorten the process

2, high precision CNC machining center parts. Because the CNC machining center has good rigidity, high manufacturing accuracy, accurate cutter and convenient size compensation, it can process parts with high dimensional accuracy requirements.

3. CNC machining center can process parts with small surface roughness value.

4. Parts with complex contour shapes.

5, the ordinary three-axis machining center can do all kinds of plane, curved surface, concave cavity, convex shape, generally the most common is the mold and mold parts

6, more advanced five-axis machining center can do more things, basically all parts can be done, even ordinary lathe, CNC lathe workpiece can be processed.
