Quality & Accuracy Commitment
GreatLight’s manufacturing philosophy revolves around “Zero Deviation, Zero Compromise.” To uphold this standard we employ:
- Closed‑Loop Control – Servo‑driven spindles with real‑time feedback ensure positional accuracy within ±0.001 mm.
- Environmental Controls – Temperature‑stabilized machining rooms (±0.5 °C) to eliminate thermal expansion errors.
- Tool Management System (TMS) – Automated tool wear monitoring, tool life prediction, and automatic tool change (ATC) for uninterrupted precision.
- In‑Process Metrology – Laser probing and touch‑probe systems validate dimensions after critical cuts, allowing immediate corrective actions.
- Final Inspection – Dual‑CMM verification (Zeiss & Mitutoyo) with GD&T reporting, supplemented by surface roughness measurement (Ra ≤ 0.2 µm for critical surfaces).
All inspection data is archived in a secure cloud‑based PLM (Product Lifecycle Management) system, providing traceability from raw material receipt to final shipment.

Machining Instructions – Best Practices
- Design Review – Submit STEP or IGES files. Our engineering team will verify wall thickness, draft angles, and feature accessibility.
- Tool Selection – Based on material hardness and geometry, we recommend carbide inserts (TiAlN coating) for aluminum/copper and CVD‑coated carbide for stainless steel/titanium.
- Clamping Strategy – Use vacuum tables for flat aluminum parts; custom fixtures for complex geometries. All clamps are CNC‑compatible to avoid deflection.
- Cutting Parameters –
- Aluminum: Spindle speed 20,000 rpm, feed 0.12 mm/tooth, depth of cut 2 mm.
- Stainless Steel: Spindle speed 8,000 rpm, feed 0.04 mm/tooth, depth of cut 0.8 mm.
- Coolant Management – High‑pressure mist for aluminum, flood coolant with anti‑rust additives for steel and titanium.
- Deburring & Finishing – Automated edge deburring stations, followed by optional CNC polishing or electroless nickel plating.
Tip: For deep‑bore holes (>30 mm), request a pilot drilling sequence with step‑drilling to extend tool life and maintain tolerance.
