Inspection surface plate is used as the main datum for measurement of the machinery parts’ geometric tolerance,such as flatness, parallelism, straightness and more. It is also can be used for precision inspection, marking out (layout), and tooling setup. The Inspection surface plate is often used as the reference plane and baseline for all measurements to the workpiece and often used with straight Edge, Square Blocks, V Blocks, Angle Plates, Parallel. etc. 檢驗(yàn)平板材質(zhì)：高強(qiáng)度鑄鐵HT200-300。校驗(yàn)平板經(jīng)過人工熱時(shí)效處理后,完全去除內(nèi)應(yīng)力，精度穩(wěn)定，耐磨性能好。工作面硬度：HB170-240。 Material: High-strength cast iron Ht200-300. After artificial heat aging treatment, the internal stress was totally eliminated, so the surface plate have stable accuracy and good wear-resisting performance. 檢驗(yàn)平板流水作業(yè) 1、檢驗(yàn)平板毛坯：按技術(shù)要求制圖紙、按圖紙制作木型、配料、造型、烘干、澆鑄、落沙、清理、檢驗(yàn)毛坯的各部位； 2、檢驗(yàn)平板毛坯回火，達(dá)到消除鑄造內(nèi)應(yīng)力的目的。 3、檢驗(yàn)平板上機(jī)床、按圖紙要求加工、送檢驗(yàn)科檢驗(yàn)； 4、檢驗(yàn)平板粗加工后回火，達(dá)到消除加工內(nèi)應(yīng)力的目的。 5、檢驗(yàn)平板工件調(diào)平、人工刮研、檢驗(yàn)科檢驗(yàn)； 6、檢驗(yàn)平板的外觀處理、噴漆、包裝、入庫 Producing Procedure of Inspection Surface Plate: 1. Rough casting: Make drawings according to the technical requirements-Making mold as per the drawings-Prepare material-Modelling-Filling sand-Drying-Casting-Surface cleaning -Casting parts testing. First time Heat treating to eliminate the internal stress 3. Rough machining: Machining as per the drawing- Casting Parts’ inspection and test. 4. Second time Heat treating and aging treatment, to eliminate the internal stress 5. Precision finishing: Leveling -Scraping- Final inspection and testing. 6 .Final finish: Painting- Packing-deliver to warehouse. The accuracy of the Cast Iron Surface Plate refers to the deviation from flatness of the working surface and it shall be classified as Grade 0,1,2,3.
