Die casting molds are important tools for manufacturing metal parts, and their processing technology includes milling, drilling, turning and other processes.

Milling process
Milling is the process of cutting mold materials into the desired shape using a milling machine. Milling processes include plane milling, vertical milling, curved surface milling, etc. Plane milling makes the surface of the workpiece flat by horizontal cutting. Vertical milling makes the side of the workpiece flat by vertical cutting. Curved surface milling makes the surface of the workpiece form the desired curved shape by curve cutting. The milling process needs to select the appropriate milling cutter type, tool path and cutting parameters according to the design requirements and processing technology of the mold to ensure the size and shape accuracy of the mold.

Drilling process
Drilling is the process of drilling mold materials using a drilling machine. Drilling processes include ordinary drilling, deep hole drilling and boring, etc. Ordinary drilling is suitable for holes with smaller diameters and shallower depths, and is processed by ordinary drill bits. Deep hole drilling is suitable for holes with larger diameters and deeper depths, and is processed by deep hole drill bits. Boring can achieve higher aperture accuracy and surface quality. The drilling process needs to select the appropriate drill type, cutting speed and feed rate according to the design requirements and processing technology of the mold to ensure the aperture accuracy and surface quality of the mold.

Turning process
Turning is a process of rotating and cutting the mold material using a lathe. Turning processes include external turning, internal turning, thread turning and grooving. External turning uses radial cutting to make the outer surface of the workpiece reach the required size and accuracy. Internal turning uses radial cutting to make the inner surface of the workpiece reach the required size and accuracy. Thread turning is processed by a feed mechanism and a thread tool. Grooving is processed by a feed mechanism and a grooving tool. The turning process needs to select the appropriate turning tool type, cutting speed and feed rate according to the design requirements and processing technology of the mold to ensure the size and shape accuracy of the mold.

Other processing technologies
In addition to conventional processing technologies, the processing of die-casting molds can also include EDM, wire cutting and polishing. EDM is the use of EDM machines to process complex shapes. Wire cutting can process small holes and complex contours. Polishing can improve the surface quality and finish of the mold. These processing techniques require the selection of appropriate equipment and process parameters according to the design requirements and processing technology of the mold to meet the processing needs of the mold.
