Machining Instructions & Best‑Practice Guidelines
- File Preparation
- Submit CAD data in STEP AP203/214, IGES, or native SolidWorks/Inventor files.
- Ensure model is watertight, with no duplicated faces or stray edges.
- Provide GD&T annotations directly on the model or in an accompanying 2‑D drawing.
- Feature Recognition & Tool Selection
- Use our in‑house CAM software (Mastercam 2024) to automatically detect pockets, slots, contours, and drill holes.
- Tool material: Carbide (solid or indexable) for aluminum & brass; Cobalt‑based or TiAlN‑coated for steel & titanium.
- Tool diameters: Minimum 0.5 mm for fine features, up to 20 mm for roughing.
- Cutting Parameters
- Aluminum: High spindle speed, light feed, generous coolant.
- Stainless Steel: Lower speed, higher feed, flood coolant to avoid chip welding.
- Copper: Moderate speed, high feed, mist coolant to prevent surface smearing.
- Brass: Similar to aluminum but with reduced spindle speed to avoid work‑hardening.
- Fixturing
- Use vacuum tables for thin plates (≤ 3 mm).
- CNC‑compatible vises, modular clamps, and custom fixtures for complex shapes.
- All fixturing is inspected for parallelism (≤ 0.02 mm) before machining.
- In‑Process Inspection
- After roughing, a probe‑based CMM checks critical dimensions.
- If deviation exceeds ±0.005 mm, the program is automatically re‑optimized.
- Post‑Processing
- Deburring (manual or automated brush).
- Surface finishing: Anodizing (Al), passivation (SS), electroless nickel (Cu/Brass), or polishing to Ra 0.1 µm on demand.
- Packaging & Shipping
- Parts Of A CNC Mill are packed in anti‑static, moisture‑controlled bags.
- For high‑precision shipments, we use ISO‑standard cushioning and GPS‑tracked logistics.

Frequently Asked Questions (FAQs)
Q1. What is the minimum order quantity (MOQ)?
A: We accept single‑piece prototypes. For production runs, the MOQ is 10 pcs for most materials, but larger batches (≥ 100 pcs) unlock additional price breaks and faster lead times.
Q2. Can you work with exotic alloys like Ti‑6Al‑4V or Inconel 718?
A: Yes. Our 5‑axis machines are equipped with high‑torque spindles and proprietary tool holders to machine titanium and nickel‑based super‑alloys. A brief material‑specific feasibility study is performed before quoting.
Q3. How do you ensure surface integrity for high‑stress applications?
A: We employ a combination of low‑cut depth, high‑frequency spindle speeds, and cryogenic or minimum‑quantity lubrication (MQL) to avoid work‑hardening. Post‑machining stress‑relief heat treatment is offered upon request.
Q4. What inspection methods are used for critical dimensions?
A: Coordinate Measuring Machines (CMM), laser scanners, and non‑contact optical comparators. For sub‑micron tolerances, we also use white‑light interferometry.
Q5. Do you provide packaging for clean‑room delivery?
A: Absolutely. Parts Of A CNC Mill can be sealed in ISO‑class 5 clean‑room bags with static‑dissipative liners, and shipped in a certified clean‑room container.
