切割過程由切割機完成，平穩(wěn)可靠、功能強大的切割機是切割工序的必要前提。隨著技術(shù)的不斷進(jìn)步，金相切割機的功能也在不斷的推陳出新，特別是以功率自適應(yīng)為主流的智能切割功能，就大大的提升了切割質(zhì)量。以國內(nèi)標(biāo)桿性金相設(shè)備企業(yè)上海川禾為例，他們推出的含有智能切割功能的Smartcut切割機，下面小編就介紹一下智能切割的功能特點。

對于非專業(yè)人士來說，要打造一個專業(yè)的金相實驗室，實在是太難了，太需要實驗室一條龍服務(wù)的廠家了。簡單來說，就是丟一個樣品給你，你幫我制樣，幫我出圖，直到我滿意，然后在原樣在復(fù)制一套給我，確保做出同樣的效果，當(dāng)然價格也得美麗……真有這樣的好事么？有，上海川禾就是國內(nèi)金相行業(yè)的一條龍服務(wù)供應(yīng)商。

金相檢測是材料分析的重要手段，簡單來說，金相分析就是在目標(biāo)材料上選取其一分析表面進(jìn)行顯微觀測，觀測面可以是尚未腐蝕表面，用來觀測類似夾雜、孔洞、裂紋等材料特征；也可以是腐蝕后表面，利用各種組織對腐蝕液的反應(yīng)速度不同，而顯現(xiàn)出深淺不一的表面形貌，從而反向說明各種組織的類型和分布方式。

由于拋光盤面本身并不具備磨削能力，所以磨粒全部有懸浮液提供，那么懸浮液中磨粒的粒徑控制直接決定拋光后劃痕的控制，優(yōu)質(zhì)的金剛石懸浮液，必須要有高成色的金剛石做保障，對于多晶金剛石懸浮液來說，顆粒的不規(guī)則程度很重要，刃口越多，磨削速度越快，拋光效果就也好；此外還要對金剛石進(jìn)行非常嚴(yán)苛的粒徑分級，防止劃痕的交叉污染。

一般來說，金相制樣包括切割，鑲嵌和磨拋三大步驟。顧名思義：切割是分切原始樣品，獲取最具代表性的目標(biāo)分析面。鑲嵌則是將切割后的樣品放入填埋樹脂內(nèi)，形成標(biāo)準(zhǔn)的樣品便于后續(xù)磨拋處理。磨拋是把目標(biāo)分析面平整化處理，消除劃痕，便于后期顯微觀測使用。

磨拋的過程一般要有粗磨、精磨和拋光三個磨拋工序，要求較高的樣品還要把拋光分為粗拋和精拋兩步來實現(xiàn)才能達(dá)到理想的觀測表面。每一步工序結(jié)束要有徹底的清潔工序，以消除上道殘留磨粒干擾下道工序。

冷鑲樹脂的固化時間長短不同，收縮量與氣泡量各異，此外固化后的硬度也有差別。在選擇冷鑲嵌樹脂時也要格外留意。

The ultimate goal of metallographic sample preparation is to prepare a flat mirror surface for observation after corrosion or direct observation. The importance of grinding and polishing is obvious. If cutting and mounting are the preliminary steps of sample preparation, then grinding and polishing are the most important steps in the sample preparation process. Friends who are fortunate enough to avoid the cutting and mounting processes should be more cautious and careful in the grinding and polishing stage, otherwise the work will fail.

Metallographic analysis is generally performed on cross-sections for microscopic observation. Most of the samples after cutting are irregular in shape, which is inconvenient to clamp and grind, so most of the cut samples need to be inlaid into a standard size. Inlay is actually to fill and cover the cut sample with liquid resin in a fixed membrane cavity. After the liquid resin is solidified, it is demolded to form a standard-shaped inlaid sample.

Cutting is the first step in the metallographic sample preparation process. The quality of cutting directly determines whether the entire sample preparation process can be successful, so it is very critical.

Metallographic sample preparation is a technical job, and cutting is the first. The quality of cutting directly determines whether the entire sample preparation process can be successful, so it is very critical. The sample maker needs to understand the basic conditions of the target material, such as the mechanical performance indicators such as hardness and strength of the material, the key observation points, and the taboo requirements of the target material. Then, according to these characteristics, the appropriate cutting process can be formulated.

For metallographic practitioners, when they see a beautiful metallographic photo, they always can't let it go, and they can't help but sigh that other people's microscopes are different. However, this is not the case. The wonderful photos are first polished, and the well-polished samples are not demanding on the microscope.
