鑄鐵平板廠家鑒于傳統(tǒng)上往往按對(duì)角線平面檢定其平面度誤差值,所以測(cè)量截面大多按米字線型分布,他是以鑄鐵平板的兩條對(duì)角線、四條邊線和兩條中線組成8個(gè)截面25個(gè)測(cè)點(diǎn)呈封閉的米字形狀,被檢裝配平板尺寸較小時(shí)可省略中線兩截面,組成六個(gè)截面9個(gè)測(cè)點(diǎn),被檢裝配平臺(tái)尺寸較大時(shí),在基礎(chǔ)上加上4條中線構(gòu)成12個(gè)截面49個(gè)測(cè)點(diǎn)。
鑄鐵平臺(tái)用途:適用于各種檢驗(yàn)工作,精密測(cè)量用的基準(zhǔn)平面,用于機(jī)床機(jī)械測(cè)量基準(zhǔn),檢查零件的尺寸精度或形位偏差,并作精密劃線。在機(jī)械制造中也是不可缺少的基本工具。
對(duì)于刮制鑄鐵平臺(tái)除檢定平面度外,還要用涂色法檢定接觸斑點(diǎn)。在邊長(zhǎng)為25mm任意正方形內(nèi)斑點(diǎn)數(shù)為:1級(jí)、2級(jí)不少于25點(diǎn);3級(jí)不少于20點(diǎn)。
泊頭市卓遠(yuǎn)機(jī)械設(shè)備制造有限公司本著團(tuán)結(jié)、敬業(yè)、信譽(yù)、創(chuàng)新、從精英團(tuán)隊(duì)塑造企業(yè)文化,以企業(yè)文化提升一流品牌。貫徹以客戶為中心,擴(kuò)大服務(wù)范圍,除繼續(xù)做好售后服務(wù)外,同時(shí)注重售前服務(wù),狠抓質(zhì)量管理,突出產(chǎn)品質(zhì)量,全面提高企業(yè)市場(chǎng)競(jìng)爭(zhēng)力。保證了為客戶設(shè)計(jì)、制造、安裝、調(diào)試一條龍服務(wù)。公司以“誠(chéng)信為本,質(zhì)量第一”為宗旨,歡迎各界朋友來公司光臨指導(dǎo),洽談業(yè)務(wù),我們?cè)概c您攜手共創(chuàng)美好明天!
In view of the fact that the cast iron flat plate manufacturer has traditionally verified the flatness error value according to the diagonal plane, the measurement cross section is mostly distributed according to the meter line type. He is composed of two diagonal lines, four side lines and two middle lines of the cast iron plate. The 25 measuring points of the section are in the shape of a closed m-shaped. When the size of the assembled panel is small, the two sections of the midline can be omitted, and six measuring points of six sections are formed. When the size of the assembled platform is large, 4 is added to the foundation. The strip center line constitutes 12 sections with 49 measuring points.
Cast iron platform use: Suitable for all kinds of inspection work, the reference plane for precision measurement, used for machine tool mechanical measurement benchmark, check the dimensional accuracy or shape deviation of parts, and make precise scribing. It is also an indispensable basic tool in machine building.
In addition to the flatness of the scraped cast iron platform, the contact spots are also determined by coloring. The number of spots in any square with a side length of 25 mm is: 1 level, 2 levels is not less than 25 points; level 3 is not less than 20 points.
