When cutting large workpiece made three of the most serious mistake, and how to avoid them

Metallographic analysis for large workpiece, cutting is the foundation of the quality process.But because of size, cutting large workpiece will it be a problem.According to expert introduction, our material phase cutting large workpiece has three major challenges, will allow you to every challenge of cutting process takes extra time, or influence the cutting quality.
This rapid troubleshooting guide will show you how to improve the efficiency of the preparation of large sample and reproducibility.

Error 1: when holding a waste of time
The correct clamping is crucial for the efficiency.Especially for large workpiece metallographic cutting.

If you use inappropriate clamping tools, clamping will greatly increase the time needed for large workpiece, affect the subsequent cutting process, do more harm than good.Worse, if no clamping, large workpiece will be more likely to move.This means that when cutting the need for additional clamping time, or, even worse will damage the samples.

Solution: using better or custom clamping tools
If often processing large workpieces, please ensure that you have a series of excellent clamping tools can choose, because have the right tools at hand can save a lot of time.

If often handle shape similar artifacts, custom clamping tool is by far the most effective choice.Customization of clamping tools can not only save you time, also can ensure consistency between the samples and a cutting wheel, reduce the cutting wheel deflection risk, to ensure that the process can be easily reproduced.

Mistake 2: because the cutting wheel error and a waste of time and resources
Cutting large workpiece, a single sample of cutting wheel wear is greater than the small artifacts, this is only because need to cut more material.If cutting wheel wear too fast, it may have to change in the middle of the cutting sequence cutting wheel, this process is very time-consuming.Therefore, you should strive for as far as possible to ensure that the least wear, and try to ensure that each group of each cutting wheel in the cutting sequence can finish most cutting.

Solution: find out the cutting wheel is appropriate for your cutting task
A number of factors (from the feed speed and the leap of cooling liquid, the material and cross section geometry) will affect the cutting quality, speed and heat damage.Our cutting wheel for a certain cutting mission is optimized.Choose the right cutting wheel, can significantly reduce the cutting wheel wear, so as to maximize the use of resources and shorten the cutting time.

Mistake 3: because with wrong cutting machine and reduce the quality
Cutting large workpiece, the contact area between the material and cutting wheel big means the risk of the heat will be bigger.Therefore, the thermal damage will be a problem.Thermal damage is refers to the material on the surface of burn, will change the material's microstructure.Must go through the plane grinding in damage, therefore, the time needed for the whole process will be extra.

Solution: use a combination of accurate cutting machine, spare parts and consumables
By choosing the most suitable for your taskCutting machine,Cooling device,Clamping toolandCutting wheelOptimize your large workpiece cutting.

Many cutting machine including special mode of automatic cutting, can guarantee the best feed speed, stable results, and less cutting wheel wear.Use Struers cutting machine, can choose three different kinds of automatic cutting mode:

• AxioCut Sweep, for fast cutting and to ensure optimum service life of cutting wheel
  Cutting wheel moves back and forth, sliding across the sample, to avoid overheating.So that we can quickly cut large workpiece, and does not produce heat damage, at the same time also can minimize the cutting wheel wear.

• AxioCut StepFor faster cutting
  Cutting wheel to move up and down along the samples, so that we can minimize contact area, to avoid overheating and thermal damage.The pattern of the cutting speed is faster than AxioCut mode, but the cutting wheel wear.

• ExciCut, used for cutting hard material, and will not produce thermal damage
  ExciCut the motion of the cutting wheel is used to reduce the contact area between the cutting wheel and the workpiece.Enabling you to cut very hard large materials, and does not produce any heat damage.At the same time, you can also use the hardness higher cutting wheel, such cutting wheel has a longer service life and can reduce costs.
