machining technology is moving toward high efficiency, high precision, high flexibility and the direction of green manufacturing.High speed milling process directly has become a key technology of the mould processing.Makino company produced the series of F forward speed of high speed and high precision machining center, provide comprehensive solutions for mould processing customers.

in recent years, with the rapid development of processing technology, the increasingly fierce market competition, customer for manufacturers of mould processing precision, complexity of process and manufacturing cycle is higher and higher requirements, and mold processing prices due to lower the market competition, industry directly using high hardness block the use of new technology such as milling mold becomes more and more common.High-speed cutting has become the mainstream of machining directly and an important development direction of advanced manufacturing technology.

Japan makino machine tool production of F series machine specially used for high speed milling, high rigidity, machine equipped with the power of 15 kw, the spindle speed of 20000 r\/min, the feed rate is as high as 20 m\/min.Using high speed machine tool spindle rigidity of

makino F front design, the unique cooling system, can guarantee under the condition of machine tool spindle at the highest speed run stably for a long time.At the same time in order to adjust the servo error and inertia machine tool dynamic performance, such as speed of the machine tool of makino F front super geometry intelligent servo control software, can advance some 150 block, thus in high speed machining surface can keep precision tool path.The technology applied in precision forging mould processing, can have very dense point and high feed rate to achieve the best cycle time.

in the above example, high-speed machining center makino F front speed gear cavity mould, can be in a machine last clamping can complete the processing, no longer need to edm.When processing can realize the unattended, need not repair the light manually, it can achieve high quality surface roughness, complete a mould processing only 5.5 h.

for precision forging mould high speed milling directly, because can obtain a better surface quality, short processing time, short production process flow and low processing cost and get more and more widely used.In high speed milling of mold directly, to better achieve the effect, should follow the following principles: (1)

overhanging cutter should be as short as possible, and in heat shrinkable type cutter holder tool handle should be long enough clamping length;

(2) climb milling method should be adopted, in order to improve the life of the cutting tool (at least 20%), and achieve better machining surface quality.

(3) vertical milling cutter circular runout error should be as small as possible;

(4) should give up wet processing, as far as possible use to the cold air to blow crumbs and cooling cutting tool;

(5) should be selected according to mould material, hardness and processing conditions suitable cutting speed and feed rate;
