Titanium alloy has a lot of exceedingly good character, it is growing continuously in the application of aviation industry and other industry. To answer this kind of trend, company of Makino of machine tool manufacturer rolled out alloy of a kind of titanium to machine new technology -- ADVAN-TiGE. According to saying, this technology can make the productivity that machines titanium alloy raises 3 times at least, cutting tool life breaks up one time. The T series that this technology uses at Makino company machining center of 5 axes horizontal, the first model of this series machine tool is the T4 with T2 and bigger norms. The treatment condition as a result of hardware manufacturer each different, be machined the characteristic of the spare parts is not identical also, because this Makino company assumes according to the experiment: The cutting tool life that existing titanium alloy machines is 1 hour, total metallic excision rate is minutely 0.

6 cubic metre inch. Next, this company had these data and the productivity that use ADVAN-TiGE technology to undertake machining and result of cutting tool life contrast. Introduce according to Makino company, ADVAN-TiGE is comprised by 5 technologies. Have the main shaft that controls capacity oneself to use sensor of displacement of many main shaft to measure the main shaft that causes by force of too big cutting to move. After the Professional 5 controller of this company receives the feedback signal that comes from sensor, according to susceptive the bear that cut bits adjusts treatment position, protect main shaft and tool system to be not damaged. This technology makes main shaft can be monitored, resolution and judgement treatment state, make response accordingly, optimize and stabilize cutting condition. Cooling and lubricant system (discharge is 52.

8gpm, pressure is 1, 000psi) can carry cooling fluid cutting tool directly / workpiece interface place, increase the capacity discharging bits of much chamfer cutting tool. Cooling system includes to go up buy type gush drenchs nozzle of head, main shaft and the cooling fluid that pass main shaft interior. In addition, the Microsizer system of this company can optimize lubricant and cooling fluid, send its to place of point of a knife, make twice of cutting tool life rises. Decrease brace up the system is based on low frequency vibration to detect, will eliminate flutter through adjusting attrition force, prevent cutting tool damage. According to saying, this system uses Kistler sensor to measure cutting power, can reduce amplitude and shorten oscillatory attenuation time. This system can move actively, mean a machine tool to be able to make response in real time. In addition, decrease actively brace up still can reduce treatment noise. Finally, the rigid structure of machining center of T series horizontal (like guide screw of big diameter ball and slideway of rigid box type) can restrain vibration further, can reduce blade of cutting tool collapse thereby, raise material purify rate.
