【正文】 由于沒有機械切削力，所以激光加工的工件變形非常小，激光切割機對加工窄槽和鉆孔非常有效 。材料在光線的照射下溫度會驟然上升并汽化。切割絲水平移動所產(chǎn)生的電火花會將材料腐蝕掉，而CNC就是用來控制水平工作臺的移動。Text Wire EDM machines utilize a very thin wire as an electrode. The wire is stretched between two rollers and cuts the part like a bandsaw. Material is removed by the erosion caused by a spark that moves horizontally with the wire. CNC is used to control horizontal table movements. 線切割機是用一根很細(xì)的切割絲做電極。這些 CNC機床能對旋轉(zhuǎn)的工件同時進行多種車削加工。通過減少零件在機床間轉(zhuǎn)移，加工中心能夠節(jié)省生產(chǎn)時間與成本。Text At a single setup machining centers can perform such operations as milling, drilling, tapping, boring, and so on. Additionally by utilizing indexing heads, some centers are capable of executing these tasks on many different faces of a part and at specified angles. Machining centers save production time and cost by reducing the need for moving a part from one machine to another. 加工中心只需一次裝卡就可以完成銑、鉆、攻絲、鏜等多種加工操作。許多加工中心還裝有可移動的長方形工作臺，即托盤系統(tǒng)。 TextTextFig 11 Components of modern CNC system 現(xiàn)代 CNC系統(tǒng)的組成 of C
