首先，工作人員一定要有豐富的機(jī)械加工工作經(jīng)驗(yàn)以及過(guò)硬的技術(shù)。機(jī)械加工必須要有過(guò)硬的技術(shù)才能做好，眾所周知機(jī)械加工是一樣精細(xì)的工作。非?？简?yàn)生產(chǎn)工藝，即便是能夠做好，也要耗費(fèi)很長(zhǎng)的時(shí)間，假如在開始做時(shí)候沒有起好頭，是很容易前功盡棄的。 </p> <p> 其次，加工工藝流程是否規(guī)范好的也決定了產(chǎn)品是否好的。這也是我們用來(lái)制定公司規(guī)章制度時(shí)候不可或缺的參考點(diǎn)。生產(chǎn)與管理都必然是需要一套完美的流程的，流程是為制作完美的產(chǎn)品而服務(wù)的。 </p> <p> 再次，生產(chǎn)環(huán)節(jié)中一定要注重溝通，不論是節(jié)點(diǎn)時(shí)間還是有問(wèn)題時(shí)，都要加強(qiáng)交流，加工廠和設(shè)備廠商的溝通是做好自動(dòng)化設(shè)備零件加工的重要條件。加工人員通常是按照?qǐng)D紙來(lái)進(jìn)行加工工作，可是更多的時(shí)候，很多工藝處所可以簡(jiǎn)化和改良，既可以降低成本，又可以提高效率。 </p> <p> <br /> </p><p> 很多零件為了提高性能都進(jìn)行熱處理工藝，例如傳感器彈性體和安裝模塊的壓頭經(jīng)過(guò)了淬火處理，稱重給料機(jī)的主軸需要調(diào)質(zhì)處理。除了產(chǎn)品設(shè)計(jì)層面，零件材料的選擇還有其它幾方面的考慮因素：產(chǎn)品經(jīng)濟(jì)性經(jīng)濟(jì)性指盡量選用價(jià)廉質(zhì)優(yōu)的材料，既能滿足機(jī)械設(shè)計(jì)的要求，又能在適用性的基礎(chǔ)上做到成本。一般來(lái)說(shuō)，會(huì)從三方面來(lái)考慮材料的經(jīng)濟(jì)性：一是材料成本。不同機(jī)械材料不僅性能差別較大，而且價(jià)格有較大差異。因此，機(jī)械設(shè)計(jì)中應(yīng)做好成本的控制，對(duì)各待選材料的經(jīng)濟(jì)性進(jìn)行分析，如果碳鋼能滿足材料性能的要求就不要選擇鈦合金；二是加工成本。工程師應(yīng)認(rèn)真分析零件生產(chǎn)所需工藝，以及生產(chǎn)中的人力財(cái)力投入情況，確定的機(jī)械材料應(yīng)用方案。這要求設(shè)計(jì)人員對(duì)產(chǎn)品的應(yīng)用條件和場(chǎng)合掌握到的非常清楚，根據(jù)零件的復(fù)雜程度以及材料加工的可能性。結(jié)構(gòu)復(fù)雜的零件可以選用鑄造毛坯，鍛造成型。對(duì)于結(jié)構(gòu)簡(jiǎn)單的零件可以用板材或者各種型材進(jìn)行焊接或鉚接方式實(shí)現(xiàn)。三是處理工藝。材料選擇的一切原則都是基于滿足應(yīng)用條件和工作狀況。例如常規(guī)的外觀處理工藝有鍍鋅、鍍鎳等各種電鍍，以及噴塑粉，噴漆，拋光，拉絲，滲氮，滲碳等。要盡量避免低效和污染的處理工藝。數(shù)控自動(dòng)車床車削外圓面的特點(diǎn)有哪些？</p><div

顯然機(jī)械零部件不都是相對(duì)規(guī)則簡(jiǎn)單的立體，但這是個(gè)有意思的問(wèn)題。首先界定下問(wèn)題，題目中的“機(jī)械零部件”都指什么呢？首先機(jī)械讓人想到的應(yīng)該是運(yùn)動(dòng)機(jī)構(gòu)，人類想要實(shí)現(xiàn)的運(yùn)動(dòng)多數(shù)只有直線運(yùn)動(dòng)和圓周運(yùn)動(dòng)，自然零件就要是柱體和旋轉(zhuǎn)掃略體。而就算想要實(shí)現(xiàn)曲線運(yùn)動(dòng)，實(shí)際上簡(jiǎn)單的四連桿機(jī)構(gòu)就能在精度滿足要求的情況下擬合絕大多數(shù)的平面閉合曲線了。而且再加上電控器件越來(lái)越便宜，我們也沒必要設(shè)計(jì)太復(fù)雜的機(jī)構(gòu)，三坐標(biāo)機(jī)器人又好又便宜。齒輪、鍵這這些首先都是零件，而不是部件，這樣解構(gòu)的話，復(fù)雜的零部件總能拆成簡(jiǎn)單形狀。當(dāng)然齒輪的漸開線線型已經(jīng)很復(fù)雜了。但另外一個(gè)重要原因，這些零件都是通用零件，保證通用就會(huì)變得簡(jiǎn)單。太復(fù)雜的看都看不懂也就沒人用了不是。除去上面的原因，其實(shí)**零件也會(huì)變得簡(jiǎn)單。這里成本導(dǎo)致的工藝選擇占了很大原因。比如小批量產(chǎn)品能用激光切割鈑金折彎，就絕不會(huì)機(jī)加工實(shí)現(xiàn)，變成一堆直棱直角帶著好多洞的鐵片。機(jī)加工的話，能用3軸床絕不用5軸，能做水平的不要做斜的，浪費(fèi)空間不說(shuō)，還不方便測(cè)量呢。再比如題主提到的鍵，鍵槽用端銑刀劃一下就出來(lái)了，別的形狀就不行了。而且絕大多數(shù)零件遠(yuǎn)沒到追求性能極限的時(shí)候。數(shù)控斜式車床主要加工什么零件？楊浦區(qū)機(jī)械制造零部件廠家</p><p
