火(huo)花機是一(yi)種機械加(jia)工(gong)(gong)(gong)設備，主(zhu)要(yao)用(yong)(yong)于(yu)電火(huo)花加(jia)工(gong)(gong)(gong)，廣泛應用(yong)(yong)在各種金(jin)屬模(mo)(mo)具(ju)(ju)、機械設備的(de)(de)制造(zao)中。它(ta)是利用(yong)(yong)浸在工(gong)(gong)(gong)作(zuo)液中的(de)(de)兩極間脈(mo)沖放電時(shi)產(chan)生的(de)(de)電蝕(shi)作(zuo)用(yong)(yong)蝕(shi)除導電材(cai)料的(de)(de)特種加(jia)工(gong)(gong)(gong)方(fang)法，又稱放電加(jia)工(gong)(gong)(gong)或電蝕(shi)加(jia)工(gong)(gong)(gong)。火(huo)花機主(zhu)要(yao)用(yong)(yong)于(yu)加(jia)工(gong)(gong)(gong)具(ju)(ju)有復雜形(xing)狀的(de)(de)型孔(kong)和(he)型腔的(de)(de)模(mo)(mo)具(ju)(ju)和(he)零件；加(jia)工(gong)(gong)(gong)各種導電材(cai)料，如硬質合金(jin)和(he)淬火(huo)鋼(gang)等(deng)；加(jia)工(gong)(gong)(gong)深細(xi)孔(kong)、異(yi)形(xing)孔(kong)、深槽、窄縫和(he)切割薄片等(deng)；加(jia)工(gong)(gong)(gong)各種成(cheng)形(xing)刀具(ju)(ju)、樣板和(he)螺(luo)紋環規等(deng)工(gong)(gong)(gong)具(ju)(ju)。

火(huo)花(hua)機(ji)采用了智能(neng)控制(zhi)技(ji)術(shu)(shu)。電火(huo)花(hua)機(ji)的智能(neng)性體現在精確的檢(jian)測(ce)(ce)技(ji)術(shu)(shu)和模糊控制(zhi)技(ji)術(shu)(shu)兩方面。在線自(zi)動監測(ce)(ce)、調整加工過(guo)程，實現加工過(guo)程的最優化控制(zhi)。模糊控制(zhi)技(ji)術(shu)(shu)是(shi)由計算機(ji)監測(ce)(ce)來判(pan)定(ding)電火(huo)花(hua)加工間(jian)隙的狀態(tai)，在保持(chi)穩定(ding)電弧(hu)的范圍內自(zi)動選擇使加工效(xiao)率達到最高的加工條件。

火(huo)花機在(zai)配有電極(ji)庫和標準電極(ji)夾具的情況(kuang)下，只(zhi)要在(zai)加(jia)(jia)工(gong)(gong)前(qian)將(jiang)電極(ji)裝(zhuang)入刀(dao)庫，編制好加(jia)(jia)工(gong)(gong)程(cheng)序，整(zheng)個電火(huo)花加(jia)(jia)工(gong)(gong)過程(cheng)便(bian)能日(ri)以(yi)赴繼地(di)自(zi)動(dong)(dong)(dong)(dong)運轉，幾(ji)乎無需人工(gong)(gong)操作(zuo)。機床的自(zi)動(dong)(dong)(dong)(dong)化(hua)(hua)運轉降低了操作(zuo)人員的勞動(dong)(dong)(dong)(dong)強度、提高生(sheng)產效率。火(huo)花機具備的自(zi)動(dong)(dong)(dong)(dong)測量找正、自(zi)動(dong)(dong)(dong)(dong)定位、多(duo)工(gong)(gong)件(jian)的連續加(jia)(jia)工(gong)(gong)等功能已較好地(di)發揮了它的自(zi)動(dong)(dong)(dong)(dong)化(hua)(hua)性能。自(zi)動(dong)(dong)(dong)(dong)操作(zuo)過程(cheng)不(bu)需人工(gong)(gong)干(gan)預，可以(yi)提高加(jia)(jia)工(gong)(gong)精度、效率。

火花機(ji)(ji)在(zai)保證加工(gong)精度(du)的(de)(de)前提下大(da)幅提高粗(cu)、精加工(gong)效率。如手機(ji)(ji)外(wai)殼、家電制品、電器用品、電子儀表等領(ling)域，都要(yao)求(qiu)將大(da)面積工(gong)件的(de)(de)放電時(shi)間大(da)幅縮短，同時(shi)又要(yao)降低粗(cu)糙度(du)。使放電后(hou)不必再進行(xing)手工(gong)拋光(guang)處(chu)理(li)。這不但縮短了加工(gong)時(shi)間且省卻后(hou)處(chu)理(li)的(de)(de)麻煩，同時(shi)提升了模具品質(zhi)，使用火花機(ji)(ji)粉末(mo)加工(gong)型(xing)可達到要(yao)求(qiu)。
