As machined
We provide high-quality as-machined services for custom components. By delivering parts directly from our advanced CNC mills and lathes, we maintain your exact geometric tolerances and eliminate the extra cost of secondary finishes. Every as-machined part is 100% deburred and cleaned, ready for immediate assembly or functional testing.
Custom As Machined Services
Our as-machined service is not limited to a single process; whether your project involves traditional milling, heavy-duty turning, specialized cutting, or high-precision grinding, we deliver this specialized service in its pure, raw state. By choosing our as-machined service, you eliminate secondary surface treatments and prevent any chemical or thermal distortion, ensuring the part respects your tightest tolerances. Our machinists strictly monitor tool wear across all operations to guarantee that our as-machined production maintains consistent tool paths, uniform textures, and zero burrs. Every metal or plastic component undergoes in-house deep cleaning and arrives ready for immediate functional testing or assembly—giving you a cost-effective contract manufacturing solution with significantly reduced lead times.
What Is an As-Machined Finish?
At its core, an as-machined surface finish 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.
Advantages of As Machined
Surface Roughness Reference (As-Machined Standard)
| Parameter | Sub-Type / Grade | Material | Appearance & Specification |
| Surface Roughness (Ra) | Ra 3.2 μm (126 μin) | Metals & Plastics | Non-Cosmetic. Cleaned, deburred, and chamfered directly after machining. Regular tool marks and minor surface scratches are visible. |
| Ra 1.6 μm (63 μin) | Metals | Non-Cosmetic. Achieving a smoother finish through optimized feed, speed, and strict tool-wear control. Fine tool marks are visible with a standard metallic shine. | |
| Dimensional Tolerance | Standard Fleet | All Materials | ±0.005 mm to ±0.01 mm based on high-rigidity machine capabilities. |
| Tool Marks | As-Machined Baseline | All Materials | Visible & Predictable. Regular feed and cut textures are present; 100% in-house deburring ensures safe, burr-free edges ready for assembly. |
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.
Zero Geometry Distortion
We are the ultimate defenders of your part’s dimensional integrity. With our As-Machined service, custom parts undergo absolutely no secondary heat treatment or chemical coating, meaning 100% of the material’s native mechanical properties and physical dimensions are preserved—completely eliminating warp and thermal deformation. Backed by our high-rigidity multi-axis fleet, we tightly control cutting heat to ensure the final deliverable matches your CAD model with micron-level consistency. No surprises, no deviations—just ready-to-assemble precision for your most rigorous functional tests.
Factory & Equipment: Supporting As-Machined
Our manufacturing facility and advanced equipment matrix are purpose-built to execute flawless custom As-Machined services. To deliver pristine raw finishes straight from your blueprints, our workshop deploys high-rigidity 3-to-5-axis CNC mills and turn-mill centers that suppress vibration and tool chatter. Equipped with premium tooling and high-pressure cooling systems, our machinery prevents surface scratching and ensures uniform, burr-free tool paths. Across all materials, our hardware guarantees that exact CAD tolerances and flawless surface aesthetics are achieved right out of the machine.
Behind Our As-Machined Services: Engineering Elite
Our premium As-Machined service is defined by the technical caliber of our engineering team. From the outset, they perform rigorous DFM analysis to adapt your unique geometries and challenging materials into flawless manufacturing strategies. By fine-tuning CAM variables to eliminate tool chatter and impact marks at the digital stage, our specialists bridge the gap between complex blueprints and immaculate physical execution. Their elite craftsmanship guarantees that your custom components arrive with pristine geometric and cosmetic integrity, allowing you to bypass traditional finishing bottlenecks and move straight to final assembly.
Our Quality Promise
For premium As-Machined components, dimensional precision is just as critical as cosmetic flawlessness. Operating under strict ISO 9001:2015 / AS9100D certified quality management systems, our quality assurance is built into every second of the machine’s runtime. Even without post-processing, every single batch undergoes a rigorous, multi-dimensional validation protocol:
We utilize advanced profilometers to verify that the surface roughness (Ra) strictly aligns with your microscopic specifications, ensuring a consistent matte or metallic luster.
Our climate-controlled quality labs leverage high-precision CMM (Coordinate Measuring Machines) and calibrated digital calipers to lock in micron-level tolerances.
Every component is manually audited under standardized lighting by trained inspectors to ensure complete eradication of micro-burrs and tool chatter.
Standardized micro-deburring and edge chamfering are applied upon request, delivering a safe-to-handle, assembly-ready component right out of the box.
Compatible Materials
We offer as-machined services for a variety of metals and plastics using various manufacturing processes, applicable to diverse fields. All materials can be provided with an as-machined finish, perfectly preserving the texture of tool marks and the material’s inherent luster.

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.
