Why This CNC Machining Service Is Ideal for Your Metal Parts
- Durability Under Load – Rotavators operate under high torque and continuous vibration. Our steel and brass alloys are heat‑treated to meet HRC 55‑60 (for carbon steel) and Brinell 200‑250 (for brass), providing the strength required for long‑life service.
- Weight Optimization – For components where mass matters (e.g., rotating arms), aluminium offers a 70 % weight reduction while maintaining structural integrity.
- Corrosion Resistance – Stainless steel grades (304, 316) and brass resist the harsh agricultural environment, extending part life.
- Precision Mesh Compatibility – Tight tolerances ensure seamless engagement with existing gear sets, eliminating premature wear and backlash.
Quality & Accuracy
GreatLight’s quality regime is built around five pillars:
- Incoming Material Inspection – X‑ray fluorescence (XRF) and chemical analysis confirm alloy composition before machining.
- In‑Process Monitoring – Laser interferometry and touch‑probe verification on each axis guarantee real‑time adherence to dimensional specs.
- Statistical Process Control (SPC) – Continuous data collection on spindle speed, feed rate, and tool wear enables predictive adjustments.
- Final Inspection – Coordinate Measuring Machine (CMM) with an accuracy of ±0.001 mm, surface roughness tester, and hardness tester.
- Documentation – Full inspection reports, material certificates (MTC), and compliance statements are delivered with every shipment.
Our quality control system is ISO‑certified, audited annually, and aligns with AS9100 for aerospace‑grade precision when required.

Machining Instructions (Best Practices)
- Design Review – Submit STL/STEP files together with tolerances and surface‑finish requirements. Our engineers will perform a DFM (Design for Machining) check and suggest optimal tool paths.
- Tool Selection – Carbide end‑mills (TiAlN coated) are recommended for steel; high‑speed steel (HSS) for aluminium; and PVD‑coated inserts for brass.
- Clamping Strategy – Use vacuum fixtures for thin CNC Machining Metal Parts; hydraulic clamps for heavy steel components. Ensure three‑point datum contact to avoid distortion.
- Coolant Management – High‑pressure mist for aluminium to avoid chip adhesion; flood coolant for steel and brass to control temperature.
- Peck Drilling – For deep holes (>30 mm) employ peck cycles to evacuate chips and reduce tool breakage.
- Finishing Passes – Conduct a light finishing pass (≤0.02 mm depth) at reduced spindle speed (≈30 % of roughing speed) to achieve the targeted Ra.
- Post‑Processing – Deburring with rotary brushes, optional anodizing for aluminium, passivation for stainless steel, and polishing for brass (if required).
