Common CNC machining questions.

Send a STEP/STP model and matching PDF drawing, plus material, quantity, finish, inspection requirements and delivery destination.

A model can support an early estimate, but it does not reliably communicate tolerance, threads, datums, roughness, finish or documentation.

STEP/STP is the preferred neutral solid format. Include a PDF drawing whenever non-geometric requirements affect acceptance.

It depends on the individual feature, material, tool access, setup, thermal behavior and inspection method. Critical values are confirmed after review.

Axis strategy and equipment are selected after geometry review. Do not assume five axes are automatically more accurate or economical than a stable indexed or 3-axis route.

Start with the exact grade and condition. Review the materials page, then submit the drawing for confirmation.

Common routes include as-machined, blasting, anodizing, passivation, powder coating, plating and black oxide, subject to material and specification review.

Yes when planned. State post-finish limits and identify masked fits, threads, contacts and datum targets.

Documentation is agreed by order. Identify dimensional reports, material records, certificates or first-article needs before quotation.

Geometry, material availability, quantity, finishing, inspection and logistics all contribute. A firm date follows completed file review.

Use a clear part number and revision on both model and drawing. Call out changed features when requesting a requote.

Global delivery can be planned against the destination, timing and commercial terms supplied in the RFQ.
