The several accuracies of a part include the accuracy of scale, shape, and appearance relative to each other's position.

常常查驗的是尺度、圓柱度、圓度、平面度、直線(xiàn)度、同軸度、平行度、筆直度、跳動(dòng)等項目。依據維修特點(diǎn)，有時(shí)不是尋求單個(gè)零件的幾許尺度，而是要求相對合作精度。

The items often checked are scale, cylindricity, roundness, flatness, straightness, coaxiality, parallelism, straightness, and runout. According to the maintenance characteristics, sometimes it is not seeking a few scales of individual parts, but rather requiring relative cooperation accuracy.

零件的外表質(zhì)量包含外表粗糙度，外表有無(wú)擦傷、腐蝕、裂紋、剝落、燒損、拉毛等缺點(diǎn)。

The appearance quality of the parts includes surface roughness, whether there are defects such as scratches, corrosion, cracks, peeling, burning, and burrs on the surface.

零件的物理力學(xué)功能 除硬度、硬化層深度外，對零件制作和修正過(guò)程中構成的功能，如應力狀況、平衡狀況、彈性、剛度、振動(dòng)等也需依據‘狀況恰當進(jìn)行檢測。

The physical and mechanical functions of parts, in addition to hardness and depth of the hardened layer, also require appropriate testing of the functions formed during the production and correction process of parts, such as stress status, balance status, elasticity, stiffness, vibration, etc., based on the condition.

零件的蔭蔽缺點(diǎn) 包含制作過(guò)程中的內部夾渣、氣孔、疏松、空泛、焊縫等缺點(diǎn)，還有運用過(guò)程中發(fā)生的微觀(guān)裂紋。

The shading defects of the parts include internal slag inclusion, porosity, looseness, hollowing, and welding seams during the manufacturing process, as well as micro cracks that occur during the application process.

零部件的質(zhì)量和靜動(dòng)平衡 如活塞、連桿組之間的質(zhì)量差，曲軸、風(fēng)扇、軸、車(chē)輪等高速轉動(dòng)的零部件的靜動(dòng)平衡。

The quality and static and dynamic balance of components, such as the quality difference between pistons and connecting rod groups, and the static and dynamic balance of high-speed rotating components such as crankshafts, fans, shafts, and wheels.

零件的資料性質(zhì)如零件合金成分、滲碳層臺碳量、各部分資料的均勻性、中石墨的拆出、橡膠資料的老化變質(zhì)程度等。

The data properties of the parts, such as alloy composition, carbon content of the carburized layer, uniformity of each part of the data, removal of graphite, aging and deterioration degree of rubber data, etc.

零件表層資料與基體的結合強度 如電鍍層、噴涂層、堆焊層和基體金屬的結合強度，機械固定聯(lián)合件的聯(lián)合強度，軸承合金和軸承座的結合強度等。

The bonding strength between the surface data of the parts and the substrate, such as the bonding strength between the electroplating layer, spraying layer, surfacing layer, and substrate metal, the bonding strength of mechanical fixed joint components, the bonding strength of bearing alloy and bearing seat, etc.

組件的合作狀況 如組件的同軸度、平行度、嚙合狀況與合作的嚴密性等。

The cooperation status of components, such as coaxiality, parallelism, meshing status, and tightness of cooperation.

鋁合金門(mén)窗設備零件的磨損程度 正確判斷沖突磨損零件的磨損程度，由磨損極限確認其是否能繼續運用。

Correctly determine the degree of wear of aluminum alloy door and window equipment parts, and determine whether they can continue to be used based on the wear limit.

密封性 如內燃機缸體、缸蓋需進(jìn)行密封實(shí)驗，查看有無(wú)走漏。

Sealing tests should be conducted on the cylinder block and cylinder head of internal combustion engines to check for leaks.

鋁合金門(mén)窗設備就是指用來(lái)加工鋁合金門(mén)窗的設備，包含雙頭切割鋸、全自動(dòng)角碼鋸、液壓組角機、端面銑床、壓力機、高速單軸仿形銑床等等。

Aluminum alloy door and window equipment refers to equipment used to process aluminum alloy doors and windows, including double head cutting saws, fully automatic angle code saws, hydraulic angle assembly machines, end face milling machines, press machines, high-speed single axis profiling milling machines, and so on.
