切割过程由切割机完成，平稳可靠、功能强大的切割机是切割工序的必要前提。随着技术的不断进步，金相切割机的功能也在不断的推陈出新，特别是以功率自适应为主流的智能切割功能，就大大的提升了切割质量。以国内标杆性金相设备企业上海川禾为例，他们推出的含有智能切割功能的Smartcut切割机，下面小编就介绍一下智能切割的功能特点。

对于非专业人士来说，要打造一个专业的金相实验室，实在是太难了，太需要实验室一条龙服务的厂家了。简单来说，就是丢一个样品给你，你帮我制样，帮我出图，直到我满意，然后在原样在复制一套给我，确保做出同样的效果，当然价格也得美丽……真有这样的好事么？有，上海川禾就是国内金相行业的一条龙服务供应商。

金相检测是材料分析的重要手段，简单来说，金相分析就是在目标材料上选取其一分析表面进行显微观测，观测面可以是尚未腐蚀表面，用来观测类似夹杂、孔洞、裂纹等材料特征；也可以是腐蚀后表面，利用各种组织对腐蚀液的反应速度不同，而显现出深浅不一的表面形貌，从而反向说明各种组织的类型和分布方式。

由于抛光盘面本身并不具备磨削能力，所以磨粒全部有悬浮液提供，那么悬浮液中磨粒的粒径控制直接决定抛光后划痕的控制，优质的金刚石悬浮液，必须要有高成色的金刚石做保障，对于多晶金刚石悬浮液来说，颗粒的不规则程度很重要，刃口越多，磨削速度越快，抛光效果就也好；此外还要对金刚石进行非常严苛的粒径分级，防止划痕的交叉污染。

一般来说，金相制样包括切割，镶嵌和磨抛三大步骤。顾名思义：切割是分切原始样品，获取最具代表性的目标分析面。镶嵌则是将切割后的样品放入填埋树脂内，形成标准的样品便于后续磨抛处理。磨抛是把目标分析面平整化处理，消除划痕，便于后期显微观测使用。

磨抛的过程一般要有粗磨、精磨和抛光三个磨抛工序，要求较高的样品还要把抛光分为粗抛和精抛两步来实现才能达到理想的观测表面。每一步工序结束要有彻底的清洁工序，以消除上道残留磨粒干扰下道工序。

冷镶树脂的固化时间长短不同，收缩量与气泡量各异，此外固化后的硬度也有差别。在选择冷镶嵌树脂时也要格外留意。

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.
