　　交流直線(xiàn)伺服電機(jī)直接驅(qū)動(dòng)進(jìn)給技術(shù)已趨成熟。數(shù)控機(jī)床的進(jìn)給驅(qū)動(dòng)有‘旋轉(zhuǎn)伺服電機(jī)精密高速滾珠絲杠’和‘直線(xiàn)電機(jī)直接驅(qū)動(dòng)’兩種類(lèi)型。傳統(tǒng)的滾珠絲杠工藝成熟加工精度較高，實(shí)現(xiàn)高速化的成本相對(duì)較低，所以目前應(yīng)用廣泛。使用滾，珠絲杠驅(qū)動(dòng)的高速加工機(jī)床移動(dòng)速度90m/min，加速度1.5g。但滾珠絲杠是機(jī)械傳動(dòng)，機(jī)械元件間存在彈性變形、摩擦和反向間隙，相應(yīng)會(huì)造成運(yùn)動(dòng)滯后和非線(xiàn)性誤差，所以再進(jìn)一步提高滾珠絲杠副移動(dòng)速度和加速度比較難了。90年代以來(lái)，高速高精的大型加工機(jī)床中，應(yīng)用直線(xiàn)電機(jī)直接驅(qū)動(dòng)進(jìn)給驅(qū)動(dòng)方式。它比滾珠絲杠驅(qū)動(dòng)具有剛度更高、速度范圍更寬、加速特性更好、運(yùn)動(dòng)慣量更小、動(dòng)態(tài)響應(yīng)性能更佳，運(yùn)行更平穩(wěn)、位置精度更高等優(yōu)點(diǎn)。且直線(xiàn)電機(jī)直接驅(qū)動(dòng)，不需中間機(jī)械傳動(dòng)，減小了機(jī)械磨損與傳動(dòng)誤差，減少了維護(hù)工作。直線(xiàn)電機(jī)直接驅(qū)動(dòng)與滾珠絲杠傳動(dòng)相比，其速度提高30倍，加速度提高10倍，達(dá)10g，剛度提高7倍，響應(yīng)頻率達(dá)100Hz，還有較大的發(fā)展余地。當(dāng)前，在高速高精加工機(jī)床領(lǐng)域中，兩種驅(qū)動(dòng)方式還會(huì)并存相當(dāng)長(zhǎng)一段時(shí)間，但從發(fā)展趨勢(shì)來(lái)看，直線(xiàn)電機(jī)驅(qū)動(dòng)所占的比重會(huì)愈來(lái)愈大。種種跡象表明，直線(xiàn)電機(jī)驅(qū)動(dòng)在高速高精加工機(jī)床上的應(yīng)用已進(jìn)入加速增長(zhǎng)期。

點(diǎn)評(píng)：活性炭對(duì)實(shí)木門(mén)甲醛的吸附作用很明顯，但是根據(jù)空間的大小不同，放置活性炭的量也有所不同。另外，活性炭吸附到一定程度后需要進(jìn)行更換。活性炭的效果雖然不錯(cuò)，但是和其他方法一樣，并不能完全清除空氣中的甲醛?？諝鈨艋骺諝鈨艋髟谖諏?shí)木門(mén)甲醛方面有一定功效，但是空氣凈化器一般只在封閉的空間使用才有效。如果在開(kāi)窗戶(hù)的情況下使用空氣凈化器，不僅沒(méi)有什么效果而且還浪費(fèi)電。甲醛捕捉劑甲醛捕捉劑也是一種吸收甲醛的有效方法。

伺服系統(tǒng)的基本要求
　　
　?。?）穩(wěn)定性好：穩(wěn)定是指系統(tǒng)在給定輸入或外界干擾作用下，能在短暫的調(diào)節(jié)過(guò)程后到達(dá)新的或者回復(fù)到原有平衡狀態(tài)。
　　
　　（2）精度高：伺服系統(tǒng)的精度是指輸出量能跟隨輸入量的程度。作為精密加工的數(shù)控機(jī)床，要求的定位精度或輪廓加工精度通常都比較高，允許的偏差一般都在0.01～0.00lmm之間。
　　
　　（3）快速響應(yīng)性好：快速響應(yīng)性是伺服系統(tǒng)動(dòng)態(tài)品質(zhì)的標(biāo)志之一，即要求跟蹤指令信號(hào)的響應(yīng)要快，一方面要求過(guò)渡過(guò)程時(shí)間短，一般在200ms以?xún)?nèi)，甚至小于幾十毫秒；另一方面，為滿(mǎn)足超調(diào)要求，要求過(guò)渡過(guò)程的前沿陡，即上升率要大。
