The ultra-thin and high-precision American QMAXIS diamond metallographic cutting blades can be used at high or low speeds, but each cutting process has its own advantages and disadvantages. Diamond particles may shatter at very high speeds and may detach at very low speeds, so it is necessary to choose an appropriate surface speed/revolution to balance these two drawbacks.

Diamond metallographic cutting blades typically have a longer service life at slower cutting speeds, but cutting at slower speeds will result in increased labor costs and other indirect costs, such as equipment depreciation and water and electricity costs. The increase in these costs will offset the saved service life of diamond metallographic cutting blades.

Diamond has higher impact strength than the material being cut. During the cutting process, diamonds shatter the material through impact, and each diamond can convert electrical energy into impact force, causing the material to break at the nanometer/micrometer level.

By increasing the power of the cutting machine, the number of blade revolutions and surface speed will also increase. Therefore, each diamond will cut less material, reducing the impact force on the material and reducing cutting resistance. In theory, increasing the surface speed/revolution will result in a smaller impact force on each diamond. However, since the impact is supported by a smaller amount, the impact force at this smaller amount actually increases. Therefore, the probability of diamond particle fragmentation or crushing is higher. Cutting materials at very low surface speeds will generate a significant impact force between the diamond and the material being cut. Although the diamond may not shatter, the risk of premature failure of the blade due to diamond detachment from the diamond cutting blade will increase.

When choosing the correct diamond metallographic cutting blade for your application, cutting speed and surface finish are often very important considerations. The operator must choose a balance point between the lifespan of the blade and the cutting speed, and cannot let your blade&# quo; Split and disintegrate&# quo;; Don't waste your precious time too slowly. You can explore a cutting speed suitable for your own sample material in practice, which can cut quickly without causing the blade to&quo; prematurely&quo; Leaving you;.
