Your Grinding Questions, Answered
To assist with your design and sourcing process, we’ve answered some of the most common technical questions about precision grinding. If you need more information, our engineering team is always ready to help.
The key is how the part is held. Cylindrical grinding holds the part between centers, best for complex profiles and shoulders. Centerless grinding rests the part between wheels, ideal for high-volume production of simple parts like pins and rods.
Specify grinding when you need:
Tolerances tighter than ±0.01mm.
Surface finishes smoother than Ra 1.6 μm for functional reasons.
To machine hardened materials (over 50 HRC).
Proper grinding induces beneficial compressive stress on the surface, which significantly increases a part's fatigue life. Our strict process control completely eliminates the risk of "grinding burn," ensuring optimal material integrity.
For best results and cost-effectiveness:
Leave stock: Allow for 0.1mm - 0.3mm of material for removal.
Add undercuts: Design reliefs for wheel clearance at shoulders.
Tolerance wisely: Apply tight tolerances only to critical features.
Key cost drivers include the tightness of the tolerance/finish, the type of material (harder materials are slower to grind), and the batch size (larger quantities reduce the per-part cost).
Yes, absolutely. This is a primary strength of grinding. We routinely machine hardened materials like tool steels and carbides up to 65 HRC and beyond.
