Subtractive Manufacturing: Tight-Tolerance CNC Machining

Computer Numerical Control (CNC) machining remains the ultimate benchmark for structural integrity, surface finish, and exact dimensional precision. At HIGH On 3D, we complement our additive systems with state-of-the-art multi-axis CNC milling and turning infrastructure. By precisely removing material from solid billets, we deliver high-accuracy prototypes, production tooling, and end-use mechanical components with tolerances as tight as ±0.01 mm across a broad spectrum of engineering metals and plastics.

As a high-precision CNC machining service provider operating alongside our additive manufacturing fleet, we offer custom metal and plastic component machining using aluminum, stainless steel, brass, and PEEK. From precision automotive jigs and defense tooling to complex aerospace prototypes, our digital plant delivers certified, high-tolerance machined parts to OEMs and engineering teams worldwide.

Tight Tolerance & Quality Inspection

Key Benefits

Delivering performance, precision, and production efficiency with every build.

Unmatched Material Integrity

Machine directly from certified solid metal stock or engineering plastics with fully isotropic mechanical properties.

Extreme Precision & Repeatability

Hold strict tolerances down to ±0.01 mm across both low-volume prototyping and mass production runs.

Superior Surface Finishes

Achieve smooth as-machined surface finishes or post-process with anodizing, bead blasting, and powder coating.

No Tooling Investment

Move straight from 3D CAD models to finished metal components without spending on preliminary casting dies or molds.

How to Get Started with CNC Machining

Upload CAD & Technical Drawings

Supported formats: .STEP, .IGES, or 2D .DWG / .DXF with GD&T.
Submit your 3D models along with 2D engineering drawings specifying critical dimensions, tolerances, and surface finish requirements.

Choose Material & Post-Processing

Select metal alloy or engineering plastic and surface finish.
Select your required material (Aluminum 6061/7075, Stainless Steel, Titanium, PEEK) and specify post-treatments like anodizing, plating, or bead blasting.

Receive Quotation & Production

Multi-axis machining, CMM inspection report, and dispatch.
Review your custom quotation, DFM feedback, and lead-time schedule before we begin precision machining and CMM quality inspection.

Frequently Asked Questions

The questions Indian buyers ask most before starting a CNC plastic machining project. Still unsure? Talk to our engineers.

When should I choose CNC machining over 3D printing?

Choose CNC machining when you need tight tolerances, a smooth surface finish, optical clarity or the full, isotropic strength of true engineering plastic. 3D printing wins for very complex geometry or the fastest single prototype; CNC wins for accuracy and real material performance.

Which plastics can you machine?

ABS, Nylon, Polycarbonate, Acrylic (PMMA), Delrin/POM, HDPE, PTFE and high-performance PEEK, among others. We help you select the right grade for strength, temperature, clarity or chemical resistance.

What tolerances can you hold?

Typically ±0.05-0.1 mm depending on material and geometry. Tighter tolerances on critical features can be discussed for your specific part.

What is the typical turnaround time in India?

Most projects are delivered within a few working days to two weeks depending on size, complexity and quantity. Share your file for an exact timeline — rush options are often available.

Do you provide GST-compliant invoicing and pan-India delivery?

Yes. We are a Pune-based, ISO 9001:2015 certified company offering fully GST-compliant invoicing and reliable, insured delivery across India — Mumbai, Bengaluru, Delhi-NCR, Chennai, Hyderabad, Ahmedabad and beyond.
