Achieve high-speed machining mold need to have the characteristics of

As technology continues to mold the development of consumer products with the accelerated replacement rate, productivity of the mold and manufacturing quality put forward higher requirements, EDM mold production inefficiencies and inconsistent quality of the shortcomings gradually exposed. China International Mould Network
To shorten the manufacturing cycle and reduce costs, must be extensive use of advanced machining technology. These tools include a variety of high-speed CNC milling machines, machining centers.
For the realization of the mold cavity and related parts of the high-speed machining, machine tools need to have the following characteristics:

(1) large load-bearing and high rigidity which is due to the direction of the mold is to develop large-scale processing equipment must have a table large enough size to adapt to and work with travel. Now, a few tons to hundreds of tons of mold are common, requiring machine work surface large heavy mold material can withstand the strength and hardness are high, with a large amount of elongation is often used small-diameter end milling mold cavity , so the process prone to flutter. To ensure the machining accuracy and surface quality, mold manufacturing, high-speed machine tool must have a high dynamic and static stiffness, in order to improve the positioning accuracy of machine tools, precision tracking and anti-vibration capabilities.

(2) high speed and high-power high-speed machining is the development direction of high-speed milling in the mold processing has shown great advantages. In order to meet the mold cavity surface processing, tool radius should be less than the minimum circle radius of the cavity surface, in order to avoid processing tool and the workpiece occur "interference." As the tool diameter is small, thus requiring very high spindle speed, and foreign high-speed machining spindle speed has reached 40000 ~ 100000r/min, rapid feed rate of up to 30000 ~ 60000min. Cavity and other parts mold parts thick, often finishing in one clamping the workpiece to complete, so the spindle power to large, medium-size molds milling and machining center spindle power often 10 ~ 40kw, some even higher.

(3) can be a good multi-axis and integrated deep cavity cutting ability of the mold cavity and more room for the complex composed of 6 surfaces and grooves, and many die with a deep cavity. In order to achieve the 3d surface accuracy, high speed processing and high reliability, multi-axis machine tool needs, and has a good comprehensive deep cavity cutting ability. You can use five-axis machining center, in addition to the three coordinates of linear motion, there are two rotating coordinate the feed movement. Multi-axis milling head or the table can feed a continuous rotation, making it ideal for machining complex parts of the mold cavity surface.

Mold compound processing is one of the development. Although the processing center has been able to many complex machining processes on a single machine to achieve, it is still not fully fit the mold processing, mechanical processing and electrical, chemical, ultrasonic and other methods of complex processing of different principles, both characteristics of two or more processes complex processing in the next mold will have broad prospects.
