Items

Suggestions

General Tolerances ±0.1 mm for standard grinding,
±0.05 mm for higher precision

Precision Tolerances ±0.005 mm to ±0.02 mm (for tight tolerances and high-precision components)

Min Wall Thickness1 mm (depending on material and part geometry)

Maximum Part Size Ø500 mm to Ø1000 mm (depending on machine capacity and component geometry)

Minimum Part Size 3 mm (can go smaller with micro-grinding or specialized tooling)

Prototyping3-5 days (depending on complexity and part size)

Low Volume 10-100 parts per run (ideal for smaller production batches or quick turnarounds)

Mass Production 1000+ parts per run (optimized for large-scale production, with tight tolerances maintained)

Lead Time 5-10 days for prototyping
2-4 weeks for low volume
4-6 weeks for mass production batches

CNC Grinding Design Guideline

CNC Grinding Design Guideline ensures optimal machining efficiency and high-precision results. Key considerations include radii, hole design, surface finish, tolerances, and wall thickness, enabling precise component production for industries like aerospace, automotive, and medical with superior surface quality.
>

Items

Suggestions

Radii and Fillets Ensure radii are ≥ 1 mm for smooth transitions;
sharper radii can cause tool wear or inaccuracies

Hole Design Keep hole diameters ≥ 3 mm to ensure proper tool engagement and minimize tool deflection

Surface Finish Aim for a Ra of 0.8-1.6 µm for general grinding,
0.1-0.4 µm for high-precision finishes

Wall Thickness ≥ 1 mm for structural integrity;
thinner walls may lead to distortion during grinding

Chamfers and Bevels Keep chamfers ≥ 1 mm to avoid excessive tool pressure or potential part damage

Tool Access and Clearance Ensure sufficient access space for the grinding wheel, typically ≥ 5 mm from the tool or fixture

Undercuts and Complex Shapes Design for accessibility with grinding wheels;
avoid undercuts that complicate machining or require special tooling

Tolerances ±0.1 mm for general grinding,
±0.02 mm for high-precision components

Min Grinding Size The minimum component size should be 3 mm to ensure adequate material removal and stability

Part Geometry Design parts with balanced symmetry to avoid uneven grinding or distortion during machining
