Grinding Wheel Specifications for Titanium
Grit Size Selection
You need to choose the right grit size to get the best finish on titanium. Grit size tells you how coarse or fine the abrasive particles are on your grinding wheel. Coarse grits remove material quickly, while fine grits give you a smooth surface. You can follow this guide to pick the right grit for each stage:
| Grit Size (Microns) | Application Stage | Expected Result |
|---|---|---|
| 60 | Initial cutting | Remove major imperfections |
| 30 | Secondary cutting | Surface leveling |
| 15 | Pre-polish | Initial shine development |
| 6 | Fine polish | Enhanced luster |
| 1 | Final polish | Mirror finish |
| 0.5 | Ultra-fine finish | Maximum brilliance |
Start with a coarse grit if you need to remove a lot of material. Move to finer grits as you get closer to your final finish. This step-by-step approach helps you avoid scratches and keeps your titanium looking its best.
Wheel Hardness and Bond Types
You should pay attention to wheel hardness and bond type when working with titanium. Hard wheels last longer, but they can cause more heat. Softer wheels wear faster, but they help keep temperatures low. For titanium, you want a balance. Resin bonds work well for fast grinding and shock absorption. Metal bonds give you better shape retention and durability. Vitrified bonds offer high precision and cool grinding. Aimgrind offers all these bond types, so you can match the wheel to your job.
Tip: If you notice your wheel loading up or burning the workpiece, switch to a softer bond or a coarser grit.
Wheel Shape and Size
You need to pick the right shape and size for your grinding job. Straight wheels work for flat surfaces. Cup wheels help you grind edges or contours. Large wheels cover more area and speed up big jobs. Small wheels give you control for detailed work. Aimgrind can customize wheel shapes and sizes to fit your machine and your process.

Why These Wheels Work for Grinding Titanium
Performance and Efficiency
You want your grinding process to be fast and smooth. The right grinding wheel helps you remove titanium quickly and with less effort. Studies show that diamond wheels, especially those with resin bonds, improve the grindability of titanium alloys. For example, researchers found that using cryogenic treatment with resin-bonded diamond wheels made titanium easier to grind. You get better surface quality, lower cutting forces, and a finer finish. Different wheels also work best at different speeds. Vitrified bonded wheels handle hard grinding jobs well. Aluminum oxide wheels perform best at lower speeds, while silicon carbide wheels work at higher speeds. You can choose the right wheel for your machine and your job.
- Diamond wheels give you high efficiency and a smooth finish.
- Vitrified wheels work well for tough grinding.

Heat Resistance and Safety
Grinding titanium creates a lot of heat. You need a wheel that can handle high temperatures without breaking down. Diamond wheels resist heat and keep your workpiece safe from burns or cracks. Safety is very important when you grind titanium. If a wheel fails at high speed, it can be dangerous.
In ultra-high-speed grinding, the speed of the grinding wheel can reach 150–300 m/s or higher, which is comparable to the muzzle velocity of a bullet. If the grinding wheel fails during operation, the debris can travel at speeds exceeding that of a bullet, posing significant safety risks to operators and causing damage to machinery. The study identifies several causes of wheel failure, including defects in the abrasive layer, powder metallurgy issues, fatigue cracks, and adhesive failures.
You should always check your wheel for cracks or damage before you start. Use the right wheel for your speed and grinding method to stay safe.
