How It Works

Precision CNC Milling & Turning

CNC machining removes material from a solid billet using computer-controlled cutting tools. FYORD runs 3-axis machining centres for prismatic parts and 4-axis for complex contours, plus CNC lathes for turned components.

Ideal for brackets, housings, shafts, flanges, heat sinks, jigs, and fixtures where sheet metal isn't enough. Tolerances tighter than ±0.025 mm achievable on request.

Milling max envelope: 500 × 300 × 150 mm
Turning max: Ø300 mm × 600 mm between centres
Surface finish Ra 0.8 – 3.2 µm standard
Thread milling, tapping, boring, and reaming in-house
ISO 2768 medium tolerance as standard

Design Guidelines

DFM Rules for CNC Parts

🔲 Cavity Depth-to-Width

Keep pocket depth ≤ 4× cutter diameter. Deep narrow pockets require special tooling and add cost. Wide shallow pockets machine faster.

🔵 Corner Radii

Internal corners need a radius ≥ tool radius. Specify R3 mm or larger where possible. Sharp internal corners require EDM — quote separately.

📏 Wall Thickness

Minimum wall thickness 0.8 mm for aluminium, 1.0 mm for steel. Thin walls vibrate during machining and reduce accuracy.

🕳️ Hole Standards

Specify drilled holes by standard drill sizes (e.g. M3 clearance = Ø3.2). Blind holes should be ≥ 3× diameter deep. Specify thread class (6H/6g).

📐 Datum & GD&T

Mark your primary datum face clearly. We machine to ASME Y14.5 GD&T if specified. Include a 2D drawing with critical tolerances called out.

🗂️ File Preparation

Upload STEP or IGES 3D model. Include a 2D PDF with all tolerances, surface finish callouts, and material / heat treatment spec.

💡 Pro tip: Adding a DXF 2D drawing alongside your STEP file cuts quoting time in half — our engineers can confirm tolerances without guessing.

FAQ

Frequently Asked Questions

What 3D file formats do you accept?▾

We accept STEP (.stp/.step) and IGES (.iges/.igs) for 3D models. For 2D turned parts, DXF or PDF with dimensions is fine. Always include a 2D drawing PDF for parts with GD&T or critical tolerances.

What is the tightest tolerance you can hold?▾

Standard is ISO 2768-m (±0.1 mm on linear, ±0.1° on angular). We routinely hold ±0.025 mm on milled features and ±0.01 mm on turned diameters. Tighter tolerances are possible with extra setup time — quote accordingly.

Do you provide inspection reports?▾

Yes — a basic dimensional check is included on all orders. A full CMM report (first article inspection) is available for ₹2,500 per part number. Our CMM is calibrated to NABL-traceable standards.

What is the minimum order quantity?▾

Minimum order value is ₹2,000. We machine single prototypes every day. Setup charges apply for quantities under 5 pieces — these are included in your quote automatically.
