五金零(ling)(ling)件加(jia)(jia)工精度(du)是加(jia)(jia)工后(hou)零(ling)(ling)件表面(mian)的實(shi)際尺(chi)寸(cun)、形狀(zhuang)、位置三種幾(ji)何(he)(he)(he)參(can)(can)數(shu)與(yu)圖紙(zhi)要求的理想幾(ji)何(he)(he)(he)參(can)(can)數(shu)的符合(he)程度(du)。理想的幾(ji)何(he)(he)(he)參(can)(can)數(shu)，對(dui)(dui)尺(chi)寸(cun)而(er)言(yan)，就是平均(jun)尺(chi)寸(cun)；對(dui)(dui)表面(mian)幾(ji)何(he)(he)(he)形狀(zhuang)而(er)言(yan)，就是絕(jue)對(dui)(dui)的圓、圓柱、平面(mian)、錐面(mian)和直線(xian)等；對(dui)(dui)表面(mian)之(zhi)間的相互(hu)位置而(er)言(yan)，就是絕(jue)對(dui)(dui)的平行、垂直、同軸、對(dui)(dui)稱(cheng)等。零(ling)(ling)件實(shi)際幾(ji)何(he)(he)(he)參(can)(can)數(shu)與(yu)理想幾(ji)何(he)(he)(he)參(can)(can)數(shu)的偏離數(shu)值稱(cheng)為(wei)加(jia)(jia)工誤差(cha)。博鑫精密(mi)是以不銹鋼零(ling)(ling)件加(jia)(jia)工、鈦(tai)合(he)金零(ling)(ling)件加(jia)(jia)工、鋼材零(ling)(ling)件加(jia)(jia)工、鋁合(he)金零(ling)(ling)件加(jia)(jia)工、鑄(zhu)件加(jia)(jia)工為(wei)公司的主打產品(pin)，品(pin)質保障，值得信賴！

一、五(wu)金零件(jian)加工精(jing)度根據不(bu)同(tong)的加工精(jing)度內容以(yi)及精(jing)度要求，采(cai)用不(bu)同(tong)的測量方法。一般來說有以(yi)下幾(ji)類方法：

1、按是否(fou)直接(jie)測(ce)(ce)(ce)量被測(ce)(ce)(ce)參數，可分為直接(jie)測(ce)(ce)(ce)量和(he)間接(jie)測(ce)(ce)(ce)量。

2、按量(liang)具(ju)量(liang)儀的讀數值是否直接表示被測尺(chi)寸的數值，可分為絕(jue)對測量(liang)和相對測量(liang)。

3、按(an)被測(ce)表(biao)面與量(liang)(liang)具量(liang)(liang)儀的測(ce)量(liang)(liang)頭是否接觸，分為接觸測(ce)量(liang)(liang)和非(fei)接觸測(ce)量(liang)(liang)。

4、按一次測(ce)量參數(shu)的多少，分為單項測(ce)量和綜(zong)合(he)測(ce)量。

5、按(an)測(ce)量(liang)在加工過程中所起的作(zuo)用(yong)，分為主動測(ce)量(liang)和被(bei)動測(ce)量(liang)。

6、按(an)被(bei)測(ce)零(ling)件在測(ce)量(liang)過(guo)程(cheng)中所處的狀(zhuang)態(tai)(tai)，分(fen)為靜態(tai)(tai)測(ce)量(liang)和動態(tai)(tai)測(ce)量(liang)。

二(er)、五金零件加工精度(du)的相關內容：

1、尺(chi)(chi)寸精(jing)度：指(zhi)加工后零(ling)件的(de)實際尺(chi)(chi)寸與零(ling)件尺(chi)(chi)寸的(de)公(gong)差帶(dai)中心的(de)相符合程度。

2、形(xing)(xing)狀精度：指加工后的(de)零件(jian)表面的(de)實際幾(ji)何形(xing)(xing)狀與理(li)想的(de)幾(ji)何形(xing)(xing)狀的(de)相符(fu)合程度。

3、位(wei)置精(jing)(jing)度：指加(jia)工(gong)后零件有(you)關表面之間的實際位(wei)置精(jing)(jing)度差別(bie)。

4、相互關系：通常(chang)在設(she)計機器零(ling)(ling)件(jian)及規定零(ling)(ling)件(jian)加(jia)工精(jing)度(du)時，應(ying)注(zhu)意將形(xing)狀(zhuang)誤差(cha)(cha)(cha)控制在位(wei)(wei)(wei)置公差(cha)(cha)(cha)內(nei)，位(wei)(wei)(wei)置誤差(cha)(cha)(cha)又應(ying)小于(yu)尺寸公差(cha)(cha)(cha)。即精(jing)密(mi)零(ling)(ling)件(jian)或零(ling)(ling)件(jian)重(zhong)要(yao)(yao)(yao)表(biao)面，其(qi)形(xing)狀(zhuang)精(jing)度(du)要(yao)(yao)(yao)求(qiu)應(ying)高(gao)于(yu)位(wei)(wei)(wei)置精(jing)度(du)要(yao)(yao)(yao)求(qiu)，位(wei)(wei)(wei)置精(jing)度(du)要(yao)(yao)(yao)求(qiu)應(ying)高(gao)于(yu)尺寸精(jing)度(du)要(yao)(yao)(yao)求(qiu)。

五金零件加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)主(zhu)要(yao)用(yong)于生產(chan)產(chan)品程度(du)(du)，加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)與加(jia)(jia)(jia)工(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)都是(shi)評價加(jia)(jia)(jia)工(gong)(gong)(gong)表面幾何參數(shu)的術語。加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)用(yong)公(gong)(gong)差(cha)(cha)(cha)等級衡量(liang)，等級值越小，其(qi)(qi)(qi)精(jing)度(du)(du)越高(gao)；加(jia)(jia)(jia)工(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)用(yong)數(shu)值表示，數(shu)值越大，其(qi)(qi)(qi)誤(wu)(wu)差(cha)(cha)(cha)越大。鈦浩(hao)機械是(shi)以機床(chuang)主(zhu)軸、回轉頂針、絲杠絲桿(gan)、軸加(jia)(jia)(jia)工(gong)(gong)(gong)、數(shu)控車床(chuang)加(jia)(jia)(jia)工(gong)(gong)(gong)、刀(dao)柄刀(dao)桿(gan)、夾頭接桿(gan)為公(gong)(gong)司的主(zhu)打產(chan)品，加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)高(gao)，就是(shi)加(jia)(jia)(jia)工(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)小，反之亦然。公(gong)(gong)差(cha)(cha)(cha)等級從IT01，IT0，IT1，IT2，IT3至IT18一共有20個(ge)，其(qi)(qi)(qi)中(zhong)IT01表示的話該零件加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)最高(gao)的，IT18表示的話該零件加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)是(shi)最低的 ，一般(ban)上IT7、IT8是(shi)加(jia)(jia)(jia)工(gong)(gong)(gong)精(jing)度(du)(du)中(zhong)等級別。

任(ren)何(he)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)法所(suo)得(de)到(dao)的(de)實際參(can)數(shu)都不會(hui)絕對準確，從零(ling)件(jian)的(de)功(gong)能看，只要加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)差(cha)在零(ling)件(jian)圖要求的(de)公(gong)差(cha)范(fan)圍內，就認為保證(zheng)了加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)。機器的(de)質量取決于零(ling)件(jian)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)質量和機器的(de)裝配質量，零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)質量包含零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)和表面質量兩(liang)大部分。機械(xie)加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)是指(zhi)零(ling)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)后的(de)實際幾何(he)參(can)數(shu)（尺(chi)寸、形(xing)狀和位置）與(yu)理想幾何(he)參(can)數(shu)相符合的(de)程度(du)。它們(men)之間的(de)差(cha)異稱(cheng)為加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)差(cha)。加(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)差(cha)的(de)大小反映了加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)的(de)高(gao)低。誤(wu)差(cha)越大加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)越低，誤(wu)差(cha)越小加(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)越高(gao)。
