FAQ About CNC Surface Grinding
What is ID Grinding (Internal Diameter Grinding)?
ID grinding is a precision process that finishes the inner surfaces of cylindrical parts, like bores or tubes, using a grinding wheel to achieve tight tolerances and smooth finishes. Ideal for aerospace, hydraulics, and bearings.
What is OD Grinding (External Diameter Grinding)?
OD grinding refines the outer surfaces of cylindrical workpieces by rotating them against a grinding wheel for precise dimensions and surface quality. Commonly used for shafts, rollers, and pistons in automotive and manufacturing.
What Are the Benefits of Choosing CNC Grinding Over Traditional Methods?
Offers automation, repeatability, and efficiency; reduces errors and time. Provides finishes down to Ra 4 microinches, minimal waste, and scalability for prototypes or large runs.
Can you help with part design or tolerancing before grinding?
Absolutely. Our engineering team can review your drawings or 3D models and suggest design-for-grindability improvements to optimize cost, precision, and manufacturability. We also assist in defining achievable tolerances and surface finishes.
