Advantages And Development Prospects Of Die Processing

Advantages and development prospects of die processing

Mold is a tool product which is widely used in manufacturing industry. No mold, die casting die, mold, deep die, and stamping die can not produce plastic parts, alloy castings, steel plates and forgings that are widely used and competitive. In the modern mass production, there is no high quality mold, and there is no high quality product. It also plays an important role in improving the production efficiency and reducing the production cost. According to the latest statistical analysis abroad, 75% of the rough parts of metal parts, 50% of finishing and 90% of plastic parts are finished by mould. Therefore, the mold industry is also known as the "crown Industry". Today, mold manufacturing has become an important part of advanced manufacturing technology.

The materials used for making moulds are usually hard to machine materials. At present, the die cavity in China is usually EDM (EDM). However, the production efficiency of electrical machining is very low. No matter in the speed of mold development or the quality of mold manufacturing, it can not meet the requirements of modern mass production.

The emergence of high speed machining technology has opened up a new way for die manufacturing technology. Replacing machining with high speed machining as far as possible is an inexorable trend to quicken the speed of mould development and improve the quality of mould manufacturing.

The main advantages of high speed machining are:

The quality of the product is good - high speed cutting speed machining the parts at about 10 times of the conventional cutting speed. The residual amount of the blank material is too short to be cut off the workpiece in a moment, and the residual stress on the surface of the workpiece is very small; the most of the heat (more than 95%) produced during the cutting process is taken away quickly by the chip. The thermal deformation of the workpiece is small; in the process of high speed machining, the spindle of the machine tool operates at a very high speed (10000 "80000 r/min"), and the vibration frequency is far away from the natural frequency range of the "machine tool - workpiece" system, and the machining process of the parts is smooth and no impact. Therefore, the parts have high machining accuracy, good surface quality, and the roughness can reach more than Ra 0.6 m. After high speed milling, the surface quality can reach the level of grinding. Therefore, many subsequent finishing processes can often be omitted.

High production efficiency - machining mould with high speed machining center or high speed milling machine can complete the coarse and fine machining of the cavity and the machining of other parts of the mold parts in one time clamping, that is, "one over" technology (One Pass Machining), the cutting speed is very high, the processing process itself is more efficient than electrical machining. It's several times higher. In addition, it does not require electrodes, often does not require subsequent manual grinding and polishing, and is easy to achieve automation of processing. Therefore, the application of high speed machining technology has greatly improved the development speed of the mould.

Prospects for development:

High speed machining has high processing precision, good surface quality and high production efficiency. The application effect of high speed machining is very good in die industry. The traditional electric machining process can't match it. It fully conforms to the development direction of "high efficiency, high precision and high automation" in modern manufacturing technology, and has a broad application prospect.
