As-Machined Finish Grades We Offer

Xtproto offers multiple as-machined surface finish options to meet different appearance, performance, and cost requirements. By optimizing cutting parameters, tool selection, and machining strategies, we can achieve different levels of surface roughness while maintaining tight dimensional accuracy.

Finish Grade Surface Roughness Description
Standard As-Machined Ra 3.2 μm / 126 μin The standard CNC machined surface finish with clearly visible tool and feed marks. This is the most cost-effective and fastest option for functional parts. Parts are deburred and sharp edges are chamfered before delivery.
Improved As-Machined Ra 1.6 μm / 63 μin A smoother machined finish achieved through optimized cutting parameters and refined tool paths. Tool marks are less visible while maintaining efficient production without additional secondary finishing processes.
Fine As-Machined Ra 0.8 μm / 32 μin The highest-quality as-machined finish achieved with precision machining strategies and specialized cutting tools. It provides minimal visible tool marks while maintaining strict dimensional and geometric tolerances.

What Is an As-Machined Finish?

At its core, an as-machined is exactly what you get fresh from the shop floor. Because it skips all post-processing, the resulting texture, roughness, and tool markings are directly determined by the machine tool, cutting parameters, and the operator’s expertise. As a as-machined contract manufacturer, we ensure that “raw” never means “careless.” Through strict tool-wear monitoring and optimized cutting paths across all our machining disciplines, our as-machined production delivers a clean, predictable, and highly consistent texture. It is the most reliable and cost-effective manufacturing option for engineering teams who require rapid-turnaround components, functional testing prototypes, or internal structural as-machined parts where structural and dimensional integrity is the only priority.

Controlled Tool Paths & Predictable Surface Roughness

In an as-machined state, visible tool marks are inevitable—but inconsistent, chaotic textures shouldn’t be. Many machine shops use “as-machined” as an excuse for worn-out tools and poor finishing passes. As a high-standard contract manufacturer, we actively eliminate this variable. By enforcing strict tool-wear monitoring and optimized tool path programming, we guarantee that the native texture of your metal or plastic parts remains uniform, visually clean, and technically predictable from the first part to the last.

100% In-House Deburring & Deep Cleaning

An as-machined designation means skipping secondary coatings—it should never mean receiving parts covered in cutting fluids, sharp burrs, or loose metal chips. We treat every raw component with industrial-grade respect. By keeping the post-machining cleaning and deburring process entirely under our roof, we ensure that while your as machined part retains its untouched dimensional profile, it is completely safe to handle and perfectly clean for its next destination.

Our Cleaning & Finishing Commitments:

Every single part undergoes strict quality checks to remove sharp edges and flashing. We guarantee a part that is safe for your assembly team to handle without altering your critical drawing dimensions.

We don't just wipe parts down. All raw components pass through our industrial ultrasonic tanks to completely dissolve and remove cutting oils, coolants, and trapped metal particles from deep holes or intricate slots.

For materials prone to oxidation, like carbon steel, we apply a temporary, clean rust-inhibitor immediately after drying. Parts are then securely packaged to ensure they arrive at your facility spotless, dry, and ready for use.

Technical Considerations & Design Tips

Select highly machinable materials (e.g., Al 6061, Brass C360) and simplify geometries. Avoid excessive aspect ratios or deep, narrow channels to suppress harmonic vibration and prevent native surface defects.

Our standard finish delivers a controlled Ra 3.2 um, with precision options down to Ra 1.6 um. Since toolpaths leave predictable directional textures, consider their orientation for any sliding, sealing, or alignment faces.

While we guarantee 100% in-house deburring for safe handling, any critical edge-engineering requirements—such as specific chamfering or micro-radius limits—should be explicitly defined on your drawing.

With zero risk of secondary coating buildup or thermal distortion, our multi-axis fleet achieves your exact CAD dimensions straight from the machine. Ensure all critical, high-precision tolerances are clearly marked.

FAQ

Is an As-Machined finish suitable for high-precision or functional parts?

Absolutely. In fact, it is preferred. Because it skips secondary thermal or chemical treatments, an As-Machined finish eliminates any risk of geometric warping or coating buildup. This preserves 100% of the material's native mechanical properties and delivers the highest possible dimensional tolerance—making it ideal for internal structural components, jigs, fixtures, and functional prototypes.

What standard surface roughness grades can Xtproto achieve straight from the machine?

Our standard baseline as-machined roughness is Ra 3.2 μm (125 µin), which is perfect for most mechanical and structural applications. Through optimized feed rates, high-rigidity workholding, and precision finishing passes, we can routinely deliver smoother finishes down to Ra 1.6 μm (63 µin) or finer upon request.

Can As-Machined parts undergo secondary surface treatments later?

Yes. An as-machined part serves as the perfect clean substrate for post-processing. Depending on your aesthetic or functional needs, you can later apply bead blasting, mirror polishing, anodizing, plating, or painting. Note: Secondary abrasive or chemical finishes may slightly alter your final dimensional tolerances, so please consult our engineering team during the DFM stage.

Do you provide inspection reports for as-machined parts?

Yes. We provide inspection reports for as-machined parts to verify critical dimensions, surface roughness, and overall machining quality. Each part is inspected under strict quality control procedures to ensure the required tolerances and as-machined finish specifications are achieved before shipment.
