Application of CNC Machine tool in Mould Machining
Mold parts production generally has the following characteristics: The mold surface is complex and irregular, and its surface shape is composed of a variety of curved surfaces, so the cavity surface and core of the mold are also complex, and even some surfaces have to be treated by mathematical calculation methods. The surface quality and dimensional accuracy of the die are required to be high. The production batch of the mold is small. There are many processing procedures. The main materials of the mold are mostly made of high-quality alloy steel, and the price is expensive. In the past, the processing of mold parts mostly depended on manual operation, but at present, mold processing. NC machining technology has been widely used.
The main ways of application of CNC machine tools in mold processing are as follows: NC milling processing such as: plastic injection mold, plastic pressing die, metal die-casting die, forging die and other cavity moulds with complex surfaces and contours. CNC EDM machining such as punching die, forging die, drawing die, plastic die, die-casting die and other parts such as deep groove, narrow groove and so on. CNC WEDM is mainly used for metal die machining of plane shape, metal die machining of three-dimensional shape, manufacture of electrodes for EDM, micro-machining and so on. NC turning mainly processes rotating parts. NC grinding
