2018北京車展：廣汽豐田電動SUV ix4 EV亮相換臉版GS4 EV

傳統(tǒng)雕刻機于手工雕刻的區(qū)別及優(yōu)勢，數(shù)控雕琢機在必定程度上改變了傳統(tǒng)的雕琢方法，縮短了手藝雕琢的時刻，在雕琢精密產(chǎn)品的功率、批量制品的一致性、曲面產(chǎn)品的雕琢方面都有著共同的優(yōu)勢!電腦雕琢機與手藝雕琢比較，有如下幾點優(yōu)勢：

1 本錢投入少，見效快

企業(yè)請一位雕琢師傅，月薪少則兩三千，多則四五千,就拿木匠雕琢來說，一個工廠的雕琢師傅都有好幾十位，多的要在上百位，這樣，一個工廠一年算下來光花在雕琢上的投入就是一筆不小的數(shù)目。電腦雕琢機一臺廉價的2萬多元，好點的也在幾萬塊，可是它的出產(chǎn)功率都是手藝雕琢的很多倍，并且，投入的本錢在短時刻內(nèi)就能夠回收。

2 雕琢?xí)r刻快

手藝雕琢一塊樣板，要一天或幾天的時刻來完結(jié)，而電腦雕琢它最多幾個小時就能夠完結(jié)，這樣也就大大地縮短了雕琢?xí)r刻，關(guān)于企業(yè)來說，時刻就意味著金錢與高效益，省下了時刻也就意味著多賺了錢。新上市的雕琢機雕琢速度更是數(shù)倍的增加，手藝速度和雕琢機速度就好比一個是步行去法國，另一個是做飛機去法國。

手藝雕琢是純手藝活，喫苦勞累，特別是現(xiàn)在的石材雕琢，收藏品雕琢，干這行的年輕人越來越少，而技藝高超的師傅們大多到了退休年齡，還有許多都做了老板，也不再親自動手了，所以雕琢師越來越緊缺，而雕琢機能夠替代一些人工，緩解人荒，能使企業(yè)正常、快速、更好地運作。而雕琢機一個人就能夠操作，并且都是電腦控制，也需求太多的電腦知識，只需通過簡略的訓(xùn)練，鼠標(biāo)點點就能完結(jié)一個雕琢著作。
