Die processing advantages and development prospects

Source: AdminPopularity:310Time: 2016-06-23SML

Mold is used in manufacturing large, affecting a wide range of surface tool products. No cavity mold, die casting mold, mold, deep drawing dies and stamping dies, it can not be widely used to produce a competitive price and plastic parts, alloy die casting, forging and steel pieces. In modern mass production, no high levels of mold, there is no high-quality products, its enterprises to improve production efficiency, reduce production costs also have an important role. According to the latest foreign statistical analysis, 75% of the metal parts roughing, finishing 90% to 50% of plastic parts is the finished mold. Thus, the mold industry is also known as the "Crown industry." Today, mold manufacturing has become an important part of advanced manufacturing technology.

Mold material is usually a class of difficult to machine materials, domestic mold cavity generally preclude the use of electrical discharge machining (EDM) molding. But EDM production efficiency is very low, both in terms of speed the development of mold or mold manufacturing quality, can not meet the modern requirements of mass production.

The emergence of high-speed processing technology for mold manufacturing technology has opened up a new road. As high-speed machining process instead of electricity, is to accelerate the speed of tooling development, improve the quality of mold manufacturing inevitable trend.

The main advantage of high-speed machining are:
Good quality - speed cutting speed higher than the conventional cut about 10 times the cutting speed of high-speed machining of parts, the remaining amount of blank material had a chance to fully deform in an instant is cut from the workpiece, the workpiece surface residual stress is very small; the vast majority of heat (over 95%) generated during the cutting chips are quickly taken away, thermal deformation of the workpiece; high-speed processing, machine tool spindles at high speed (10000 "80000 r / min) operation, exciting frequency is far away "machine - workpiece - tool" natural frequency range of the system, the smooth processing of parts and therefore no impact on the high machining accuracy, good surface quality, roughness up to Ra 0.6μm or more after high speed milling. cavity surface quality to reach the level of grinding, it often can save a lot of subsequent finishing operations.

Prospects:
High-speed machining precision, good surface quality, high production efficiency, application results in the mold industry is very good, traditional electric processing technology can not match it, in full compliance with modern manufacturing technology, "high efficiency, high precision and a high degree of automation "direction of development, have broad application prospects.
