5-axis CNC machining combines three linear axes with two rotary axes to reach angled faces and complex contours with fewer setups. It is useful when features on several faces must stay aligned to a shared datum.
Typical parts and project fit
This process is considered for brackets, impellers, optical mounts and complex housings. Tecpreva reviews the drawing, material condition, quantity and functional requirements before confirming the production route.
Drawing and inspection checklist
Identify tool access, rotary clearance, datum transfer and thin-wall distortion. Supply a revision-controlled 2D drawing, STEP model, finish specification and critical dimensions. Machine positioning accuracy alone does not define achievable part tolerance.
When should I choose 5-axis rather than 3-axis machining?
Choose 5-axis when it improves access or reduces setups for angled and multi-face features. Simple prismatic parts may be more economical on 3-axis machines. The drawing and inspection plan determine the route.
From first article to repeat production
Agree the fixture and datum strategy, first-article checks, sampling plan and dimensional report scope before production. Record revisions and protect functional surfaces during finishing and packing.
