五(wu)金(jin)零件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)精(jing)(jing)度(du)是(shi)加(jia)(jia)工(gong)(gong)(gong)后(hou)零件(jian)(jian)表面的(de)(de)(de)實際(ji)尺寸、形狀、位置(zhi)三種幾(ji)何(he)(he)參(can)數與(yu)圖紙要(yao)求的(de)(de)(de)理想幾(ji)何(he)(he)參(can)數的(de)(de)(de)符合(he)程度(du)。理想的(de)(de)(de)幾(ji)何(he)(he)參(can)數，對尺寸而言，就是(shi)平均尺寸；對表面幾(ji)何(he)(he)形狀而言，就是(shi)絕對的(de)(de)(de)圓(yuan)、圓(yuan)柱、平面、錐面和直(zhi)線等(deng)(deng)；對表面之間的(de)(de)(de)相互(hu)位置(zhi)而言，就是(shi)絕對的(de)(de)(de)平行、垂直(zhi)、同(tong)軸(zhou)、對稱(cheng)等(deng)(deng)。零件(jian)(jian)實際(ji)幾(ji)何(he)(he)參(can)數與(yu)理想幾(ji)何(he)(he)參(can)數的(de)(de)(de)偏(pian)離數值稱(cheng)為加(jia)(jia)工(gong)(gong)(gong)誤差。博鑫精(jing)(jing)密是(shi)以不(bu)銹(xiu)鋼(gang)零件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)、鈦合(he)金(jin)零件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)、鋼(gang)材零件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)、鋁合(he)金(jin)零件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)、鑄件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)為公司的(de)(de)(de)主打產品，品質(zhi)保(bao)障，值得信賴！

一、五金零(ling)件加(jia)工精度(du)根據不同的加(jia)工精度(du)內容以及精度(du)要求(qiu)，采用不同的測(ce)量方法。一般來說有(you)以下(xia)幾類方法：

1、按是(shi)否直(zhi)接測量(liang)(liang)被測參數(shu)，可分為(wei)直(zhi)接測量(liang)(liang)和間接測量(liang)(liang)。

2、按量具量儀的(de)讀數值是否直接(jie)表示被測(ce)尺寸的(de)數值，可分為絕對(dui)測(ce)量和(he)相(xiang)對(dui)測(ce)量。

3、按被測表面與量(liang)(liang)具量(liang)(liang)儀(yi)的測量(liang)(liang)頭(tou)是否(fou)接觸，分為(wei)接觸測量(liang)(liang)和(he)非接觸測量(liang)(liang)。

4、按一次測量參數的多少，分為(wei)單項測量和(he)綜合測量。

5、按測量(liang)在加工過程中所(suo)起的作用，分為主動(dong)測量(liang)和被動(dong)測量(liang)。

6、按(an)被測(ce)(ce)零件在測(ce)(ce)量過程中所(suo)處的(de)狀態，分為靜態測(ce)(ce)量和動(dong)態測(ce)(ce)量。

二、五金零件加工精度(du)的相關內容：

1、尺(chi)寸精度：指加工后零(ling)件的(de)實際(ji)尺(chi)寸與零(ling)件尺(chi)寸的(de)公差帶中心的(de)相符合程度。

2、形狀(zhuang)精度(du)：指(zhi)加工后的(de)零件表面的(de)實際幾(ji)(ji)何形狀(zhuang)與理想(xiang)的(de)幾(ji)(ji)何形狀(zhuang)的(de)相符合程度(du)。

3、位置精度(du)：指加工后零件有(you)關表(biao)面之間的(de)實(shi)際(ji)位置精度(du)差別。

4、相(xiang)互關系：通常在設計機(ji)器零(ling)件(jian)(jian)及規定零(ling)件(jian)(jian)加工精(jing)(jing)度(du)(du)(du)時，應(ying)注意將(jiang)形狀誤(wu)差控制在位(wei)置公(gong)差內，位(wei)置誤(wu)差又應(ying)小于尺(chi)寸公(gong)差。即(ji)精(jing)(jing)密零(ling)件(jian)(jian)或零(ling)件(jian)(jian)重要(yao)(yao)表(biao)面(mian)，其形狀精(jing)(jing)度(du)(du)(du)要(yao)(yao)求(qiu)應(ying)高于位(wei)置精(jing)(jing)度(du)(du)(du)要(yao)(yao)求(qiu)，位(wei)置精(jing)(jing)度(du)(du)(du)要(yao)(yao)求(qiu)應(ying)高于尺(chi)寸精(jing)(jing)度(du)(du)(du)要(yao)(yao)求(qiu)。

五金(jin)零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)主要用于生產產品(pin)程度(du)(du)(du)(du)，加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)與(yu)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)誤(wu)差(cha)都是評價加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)表(biao)面幾何參數(shu)的術語。加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)用公差(cha)等(deng)級衡量，等(deng)級值(zhi)越(yue)小，其精(jing)(jing)度(du)(du)(du)(du)越(yue)高(gao)；加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)誤(wu)差(cha)用數(shu)值(zhi)表(biao)示(shi)，數(shu)值(zhi)越(yue)大，其誤(wu)差(cha)越(yue)大。鈦(tai)浩機械是以機床主軸、回(hui)轉(zhuan)頂針、絲杠絲桿、軸加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)、數(shu)控車床加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)、刀柄刀桿、夾頭接(jie)桿為公司的主打產品(pin)，加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)高(gao)，就是加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)誤(wu)差(cha)小，反(fan)之(zhi)亦然。公差(cha)等(deng)級從IT01，IT0，IT1，IT2，IT3至IT18一共有(you)20個，其中(zhong)IT01表(biao)示(shi)的話(hua)該零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)最高(gao)的，IT18表(biao)示(shi)的話(hua)該零(ling)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)是最低的 ，一般上IT7、IT8是加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)精(jing)(jing)度(du)(du)(du)(du)中(zhong)等(deng)級別。

任(ren)何加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)方法所得到的(de)(de)實(shi)際(ji)參數(shu)都不會絕對準確，從零(ling)件(jian)的(de)(de)功(gong)能(neng)看，只要(yao)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)在(zai)零(ling)件(jian)圖要(yao)求的(de)(de)公差(cha)(cha)范圍(wei)內，就認為保(bao)證了(le)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)。機器(qi)(qi)的(de)(de)質(zhi)量(liang)取決于零(ling)件(jian)的(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)質(zhi)量(liang)和(he)機器(qi)(qi)的(de)(de)裝(zhuang)配質(zhi)量(liang)，零(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)質(zhi)量(liang)包(bao)含零(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)和(he)表(biao)面質(zhi)量(liang)兩大(da)(da)部分。機械加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)是(shi)指零(ling)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后的(de)(de)實(shi)際(ji)幾何參數(shu)（尺寸、形(xing)狀和(he)位置）與(yu)理(li)想(xiang)幾何參數(shu)相符合的(de)(de)程度(du)。它們之間的(de)(de)差(cha)(cha)異稱為加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)。加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)誤(wu)(wu)差(cha)(cha)的(de)(de)大(da)(da)小(xiao)反(fan)映了(le)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)的(de)(de)高低。誤(wu)(wu)差(cha)(cha)越(yue)(yue)大(da)(da)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)越(yue)(yue)低，誤(wu)(wu)差(cha)(cha)越(yue)(yue)小(xiao)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精(jing)(jing)度(du)越(yue)(yue)高。
