As-Machined (Standard) Surface Finish

As-Machined” is the standard finish for all CNC milled and turned parts. It involves no secondary post-processing such as bead blasting, anodizing, or polishing. Parts are cleaned, deburred to remove sharp edges, and shipped with the visible tool path patterns from the cutting process.

Visual Characteristics

  • Tool Marks: Visible swirls or lines are present on the surface. These marks follow the path of the cutting tool (e.g., circular marks from facing, linear marks from side milling).
  • Texture: The surface feels smooth to the touch but has a slight texture due to the ridges of the tool path.
  • Uniformity: The pattern is consistent across machined surfaces, but different faces may show different patterns depending on the machining strategy.

Important Note on Deburring

Even with an “As-Machined” finish, we always perform edge breaking (deburring). Raw CNC parts have razor-sharp edges. Unless otherwise specified, we use tumbling or manual deburring tools to create a small chamfer or radius on all exposed edges for safety and handling.

FAQs About CNC Machining Services

Standard lead times are typically 10–15 business days. Expedited services (Rapid Prototyping) can be completed in as little as 3–5 business days, depending on part complexity and material availability.

In most cases, we source materials from our approved suppliers to ensure quality control. However, we can machine customer-supplied materials for specialized alloys or specific requirements upon engineering review.

Unless otherwise specified, our general tolerance standard is ISO 2768-m (±0.125 mm) for metals and ±0.25 mm for plastics. Precision tolerances ±0.005 mm are achievable but must be explicitly stated in 2D technical drawings.

Our facility can accommodate parts up to 4000 x 1500 x 600 mm for milling and Ø200 mm x 500 mm for turning.

Yes. We can install inserts (e.g., Helicoils, PEM fasteners) and perform basic mechanical assembly of machined components prior to shipment.

To provide an accurate quote, we require a 3D CAD file (STEP, IGES, or X_T format). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

We take IP protection seriously. All files are stored securely, and we are willing to sign a Non-Disclosure Agreement (NDA) prior to receiving your data.

Yes. We can provide material certificates (COA) and dimensional inspection reports upon request. Please specify this requirement when placing your order.

We ship globally using major carriers (DHL, FedEx, UPS). Shipping terms are typically Ex Works (EXW) or DAP, depending on the agreement.
