Metal processing enterprises generally have quality control laboratories, the main purpose of which is to test the product quality and ensure that the product quality is qualified. In addition to the physical and chemical inspection of products, metallographic inspection is often required. Metallographic sample cutting is the initial step of metallographic inspection, which is inseparable from these metallographic cutting machines.


Metallographic cutting is mainly to cut samples from large blocks to be tested by metallographic cutting machine. The requirement is to avoid changing the microstructure of the area to be tested during the cutting and sampling process. According to the material properties and size of the sample, different types and models of metallographic cutting machines need to be selected. Metallographic cutting equipment is mainly divided into two categories: grinding wheel metallographic cutting machine and precision metallographic cutting machine.

1. Grinding wheel metallographic cutting machine


Grinding wheel metallographic cutting machine is the metallographic sample cutting equipment of cooling cutting method adopted by most laboratories. There are two types of grinding wheel metallographic cutting machines, manual and automatic. They are good at fast cutting speed and high efficiency. They are suitable for most metal materials. According to the hardness of different metal materials, the appropriate metallographic grinding wheel cutting blade can be selected. Generally, manufacturers have a complete range of consumables with complete models.


However, its shortcomings are also very significant. It is not effective for those small, precise, hard and fragile metallographic samples. At this time, it is necessary to configure a precision metallographic cutting machine.

2. Precision metallographic cutting machine


The precision metallographic cutting machine is more suitable for cutting the small, precise, hard and fragile metallographic samples mentioned above. However, it is specially designed for the samples with these characteristics. It is suitable for most metal materials. According to the hardness of different metal materials, the appropriate precision metallographic cutting pieces can be selected. Generally, manufacturers have a complete range of consumables with models and types.


However, compared with the grinding wheel metallographic cutting machine, the slow cutting speed and low efficiency are the weaknesses of the precision metallographic cutting machine, which must be accepted!


The two have their own advantages and disadvantages. How to choose? The editor suggested that it would be more economical and practical to choose the grinding wheel metallographic cutting machine under the condition of meeting the technical requirements. Otherwise, we have to choose the precision metallographic cutting machine. The basic principle of everything is to meet the technical needs. This is Xiaobian's personal point of view, which is for your reference only. Specific problems need to be analyzed and treated in detail.
