Grinding discs ใบเจียร are oftentimes thought of as a rough tool to remove a lot of material fast. That said, when used with finesse and the correct techniques, they can also produce very high-quality finishes on a number of materials. Whether you are extracting metal or wood grinding wheels for completing, you can have everything you need to provide you with a new professional surface.
Why Should You Opt Grinding Discs for Finishing?
- Best polish efficiency: After you have left hand sanding and after aggressive rotaries, grinding disks will almost polish the surface to get it perfectly level.
- Different applications: They can be used on a range of different materials, so they work well for a variety of projects.
- Control – Best for achieving accurate results and a finish that best suits your requirements, Requires some practice.
- Affordable: Grinding discs are relatively inexpensive and can be used for many projects.
Selecting the Best Grinding Disc
- The secret to the perfect finish is in the choice of grinding disk. Here’s what to consider:
- When working with sandpaper, use a higher grit (40-60) in the beginning to get off the stubborn material and move to a lower grit (80-120+) for finishing touches.
- Type:
- Flap discs: These discs are really good for blending and contouring for curved surfaces.
- Fiber discs – best used on flat surfaces, more common general-purpose finishing.
- Sanding discs: These are just sand paper you put on a sander, except this type lasts a little bit longer, and actually cuts a little faster and better than sandpaper.
- Job Material: Different materials from you are working, such as zirconia alumina for steel, silicon carbide for non-ferrous metals.
How to Get a Smooth Finish
Start with a clean surface:Before grinding, clean the cup disc to avoid wear and tear on the disc and scratching the surface.
- Light Pressure: Allow the disc to do the work. High pressure will create gouges and unevenness.
- Flat Against Surface: Maintain an angle where the disc is flat against the surface without tilting one way or the other, otherwise you will create low or high spots.
- Pass Overlap: Slightly overlap each pass so there is smooth material removal and no visible lines.
- Keep it Delicately Moving: Excessive focusing on one spot may cause overheating and discoloration.
- Coolant: Apply lubricant or coolant to reduce friction, decrease risk of overheating and extend the disc life.
- Work your way through the different grit numbers: Begin with a coarser grit to remove blemishes and work your way up progressively with finer grits until it is perfectly smooth.
- Final Polish: For a super smooth surface you may consider finally polishing using a polishing compound or with buffing wheel after grinding.
Safety Precautions
- Safety first: you should always have safety glasses, hearing protection and a respirator.
- Clamp down – Make sure to properly secure the material to avoid them wiggling around during the grinding process.
- Inspect the plate: Verify the integrity and detection before using the plate. Replace worn discs promptly.

Troubleshooting Common Issues
Inconsistent Finish: Due to different pressure or angle. Practice on scraps of leather to get the hang of it.

Conclusion
Grinding discs are not just limited to rough shaping; they can also be used to achieve fine finishes that look professional. With a little determination and if approached cautiously with safety in mind, you can make your billable projects something you output pretty fantastic because you might just learn to love sanding, just maybe. Practice makes perfect, so go ahead and experiment and master your craft.
