Is the selection of grinding and polishing consumables always unsatisfactory? Starting from materials and processes, obtain stable sample preparation results in 3 steps
2026-05-29
Have you encountered the following situations during the actual grinding and polishing process
Referring to mature formulas for selecting consumables, the sample results showed obvious scratches and uneven surfaces; Repeated trial and error of different consumables combinations results in low efficiency and increased costs, but still cannot achieve the desired surface quality.
The root cause of these problems often lies not in the equipment or operating methods, but in the insufficient matching between grinding and polishing consumables, materials, and process steps.
Choosing the right consumables is not simply copying experience, but requires systematic selection based on material characteristics, goals at each sampling stage, and overall process stability. Starting from practice, we will outline three core steps to improve sample preparation efficiency and result consistency.
Step 1: Select abrasives and grinding surfaces based on material properties
The hardness, ductility, and brittleness of materials directly determine their response behavior to grinding and polishing.
Hard and brittle materials (such as ceramics and hard alloys): prone to cracking or deep scratches, it is recommended to use a rigid grinding surface combined with diamond abrasive.
Soft and tough materials (such as copper, aluminum, polymer materials): prone to plastic deformation or tailing, suitable for using flexible grinding surfaces combined with silicon carbide or fine-grained diamond abrasives.
Step 2: Divide tasks according to the sample preparation stage to avoid the misconception of "one step at a time"
Different sample preparation stages correspond to different process objectives, and mixing or omitting intermediate steps are common reasons for unstable results.
Coarse grinding (flat grinding): The goal is to quickly remove materials and adjust the surface, and consumables with coarse particle size and high removal rate should be selected.
Fine grinding: The goal is to remove rough scratches and obtain a flat surface, suitable for medium particle size, rigid or semi-rigid grinding surfaces.
Polishing: The goal is to obtain a mirror like or non-destructive surface, and it is recommended to use fine-grained soft cloth with polishing solution (such as diamond or oxide suspension).
Step 3: Choose a matching system to ensure reproducible results
There are significant differences in particle size standards, adhesive properties, and abrasive distribution uniformity among different brands of consumables. Mixing brands can easily lead to sample drift and increase the difficulty of process control.
Naibo's grinding and polishing consumables (including diamond grinding discs, silicon carbide sandpaper, polishing cloth, polishing solution, etc.) are designed with self-developed sample methods and have the following advantages:
Different operators can obtain consistent results for the same batch of samples;
Each step from rough grinding to polishing has a clearly matched product;
Effectively reduce trial and error costs and lower the overall cost of consumables usage.
By selecting the right grinding and polishing consumables, one only needs to follow the three principles of "material characteristics → step division → stable matching" to achieve efficient, accurate, and reproducible sample results.
If you are unsure which consumables your material is suitable for, please leave a message explaining the material type and sample requirements. Naibo provides a full range of grinding and polishing consumables, and engineers provide one-on-one professional selection recommendations.
