五金(jin)(jin)零(ling)(ling)(ling)件加工(gong)精度是(shi)加工(gong)后零(ling)(ling)(ling)件表(biao)面的(de)實際尺(chi)寸、形狀(zhuang)、位置(zhi)三種幾何(he)(he)參(can)(can)(can)數(shu)(shu)(shu)與圖紙要(yao)求(qiu)的(de)理想幾何(he)(he)參(can)(can)(can)數(shu)(shu)(shu)的(de)符合(he)程度。理想的(de)幾何(he)(he)參(can)(can)(can)數(shu)(shu)(shu)，對(dui)尺(chi)寸而(er)言(yan)，就是(shi)平均(jun)尺(chi)寸；對(dui)表(biao)面幾何(he)(he)形狀(zhuang)而(er)言(yan)，就是(shi)絕對(dui)的(de)圓(yuan)、圓(yuan)柱、平面、錐面和直線(xian)等；對(dui)表(biao)面之間(jian)的(de)相(xiang)互(hu)位置(zhi)而(er)言(yan)，就是(shi)絕對(dui)的(de)平行(xing)、垂直、同軸、對(dui)稱(cheng)等。零(ling)(ling)(ling)件實際幾何(he)(he)參(can)(can)(can)數(shu)(shu)(shu)與理想幾何(he)(he)參(can)(can)(can)數(shu)(shu)(shu)的(de)偏離數(shu)(shu)(shu)值稱(cheng)為(wei)加工(gong)誤差(cha)。博鑫精密是(shi)以不銹(xiu)鋼零(ling)(ling)(ling)件加工(gong)、鈦合(he)金(jin)(jin)零(ling)(ling)(ling)件加工(gong)、鋼材零(ling)(ling)(ling)件加工(gong)、鋁合(he)金(jin)(jin)零(ling)(ling)(ling)件加工(gong)、鑄件加工(gong)為(wei)公司的(de)主打產品，品質保障，值得信賴！

一(yi)、五金零件加工(gong)精度根據不(bu)同的(de)(de)加工(gong)精度內(nei)容以(yi)及精度要求(qiu)，采用不(bu)同的(de)(de)測量方法。一(yi)般(ban)來說有以(yi)下幾(ji)類方法：

1、按是否直接測量(liang)(liang)被測參數(shu)，可分為直接測量(liang)(liang)和間接測量(liang)(liang)。

2、按量(liang)(liang)具量(liang)(liang)儀的(de)(de)讀數值是否直接(jie)表(biao)示被測尺寸的(de)(de)數值，可分為絕對測量(liang)(liang)和相對測量(liang)(liang)。

3、按被測表面(mian)與量具(ju)量儀的測量頭(tou)是否接觸(chu)，分(fen)為接觸(chu)測量和(he)非接觸(chu)測量。

4、按一次測量參數的多少，分為(wei)單(dan)項測量和綜合測量。

5、按測量(liang)在加工過(guo)程中(zhong)所(suo)起的作用，分(fen)為主(zhu)動(dong)測量(liang)和被動(dong)測量(liang)。

6、按被(bei)測(ce)零件在測(ce)量過(guo)程中所處(chu)的狀態(tai)，分為靜態(tai)測(ce)量和(he)動態(tai)測(ce)量。

二、五金(jin)零(ling)件加工精度的相關內容：

1、尺寸精度：指加工(gong)后零件(jian)的(de)實際尺寸與(yu)零件(jian)尺寸的(de)公差帶(dai)中心的(de)相符合程度。

2、形(xing)(xing)狀精(jing)度：指加(jia)工后(hou)的(de)零件表(biao)面(mian)的(de)實際幾何形(xing)(xing)狀與理想的(de)幾何形(xing)(xing)狀的(de)相符(fu)合程度。

3、位(wei)置(zhi)(zhi)精度：指加工后零件有(you)關表面之間的(de)實際位(wei)置(zhi)(zhi)精度差別(bie)。

4、相互(hu)關系：通常在設計機器零(ling)件(jian)及(ji)規定零(ling)件(jian)加工精度(du)時，應(ying)(ying)注(zhu)意將形(xing)狀(zhuang)(zhuang)誤差控制在位(wei)置(zhi)(zhi)公(gong)差內，位(wei)置(zhi)(zhi)誤差又應(ying)(ying)小(xiao)于尺(chi)寸(cun)(cun)公(gong)差。即(ji)精密零(ling)件(jian)或(huo)零(ling)件(jian)重(zhong)要(yao)(yao)表面，其形(xing)狀(zhuang)(zhuang)精度(du)要(yao)(yao)求(qiu)應(ying)(ying)高于位(wei)置(zhi)(zhi)精度(du)要(yao)(yao)求(qiu)，位(wei)置(zhi)(zhi)精度(du)要(yao)(yao)求(qiu)應(ying)(ying)高于尺(chi)寸(cun)(cun)精度(du)要(yao)(yao)求(qiu)。

五金(jin)零(ling)件加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)主(zhu)要用于生產產品程度(du)(du)(du)，加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)與加(jia)工(gong)(gong)(gong)(gong)誤差都(dou)是(shi)(shi)(shi)評價加(jia)工(gong)(gong)(gong)(gong)表(biao)面幾何參數(shu)的(de)術語。加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)用公差等(deng)(deng)(deng)級(ji)衡(heng)量，等(deng)(deng)(deng)級(ji)值(zhi)越小，其精度(du)(du)(du)越高；加(jia)工(gong)(gong)(gong)(gong)誤差用數(shu)值(zhi)表(biao)示，數(shu)值(zhi)越大，其誤差越大。鈦(tai)浩機械是(shi)(shi)(shi)以(yi)機床(chuang)主(zhu)軸(zhou)、回轉頂(ding)針、絲杠絲桿(gan)、軸(zhou)加(jia)工(gong)(gong)(gong)(gong)、數(shu)控(kong)車(che)床(chuang)加(jia)工(gong)(gong)(gong)(gong)、刀柄刀桿(gan)、夾頭(tou)接(jie)桿(gan)為(wei)公司的(de)主(zhu)打產品，加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)高，就是(shi)(shi)(shi)加(jia)工(gong)(gong)(gong)(gong)誤差小，反之亦然。公差等(deng)(deng)(deng)級(ji)從(cong)IT01，IT0，IT1，IT2，IT3至(zhi)IT18一(yi)共有(you)20個，其中IT01表(biao)示的(de)話該零(ling)件加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)最高的(de)，IT18表(biao)示的(de)話該零(ling)件加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)是(shi)(shi)(shi)最低(di)的(de) ，一(yi)般(ban)上IT7、IT8是(shi)(shi)(shi)加(jia)工(gong)(gong)(gong)(gong)精度(du)(du)(du)中等(deng)(deng)(deng)級(ji)別。

任何(he)加(jia)工(gong)(gong)(gong)(gong)方法所得(de)到的(de)實際參(can)數(shu)都不會(hui)絕對準確，從零(ling)(ling)件的(de)功能(neng)看，只要加(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)(cha)在零(ling)(ling)件圖要求(qiu)的(de)公差(cha)(cha)(cha)(cha)范圍內，就認為(wei)保證(zheng)了(le)加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度。機(ji)器的(de)質(zhi)(zhi)(zhi)量(liang)取決于零(ling)(ling)件的(de)加(jia)工(gong)(gong)(gong)(gong)質(zhi)(zhi)(zhi)量(liang)和機(ji)器的(de)裝配質(zhi)(zhi)(zhi)量(liang)，零(ling)(ling)件加(jia)工(gong)(gong)(gong)(gong)質(zhi)(zhi)(zhi)量(liang)包含零(ling)(ling)件加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度和表面質(zhi)(zhi)(zhi)量(liang)兩大(da)(da)部分(fen)。機(ji)械(xie)加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度是指(zhi)零(ling)(ling)件加(jia)工(gong)(gong)(gong)(gong)后的(de)實際幾何(he)參(can)數(shu)（尺寸、形狀(zhuang)和位置）與理想幾何(he)參(can)數(shu)相(xiang)符合的(de)程度。它們之間的(de)差(cha)(cha)(cha)(cha)異稱(cheng)為(wei)加(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)(cha)。加(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)(cha)(cha)的(de)大(da)(da)小反(fan)映了(le)加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度的(de)高低。誤(wu)(wu)差(cha)(cha)(cha)(cha)越大(da)(da)加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度越低，誤(wu)(wu)差(cha)(cha)(cha)(cha)越小加(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度越高。
