Why Choose Kemal for 5-Axis Machining
Free DFM Report
Upload your STEP file and key tolerances. We’ll send back a practical DFM report—tool access and collision risks (deep pockets, angled features), recommended fillets/chamfers, datum, and one-setup fixturing strategy, and the critical dimensions most likely to drift. You get a controlled machining plan before we cut metal, not trial-and-error.
Predictable Lead Times
We run 5-axis machining in-house—no capacity hand-offs. Programming, setups, and inspection stay in one workflow. Before cutting metal, we complete a DFM check to lock tool access and the setup plan, reducing rework. You get clear milestones (DFM → programming → first article → inspection → finishing → shipment) with proactive updates.
5-Axis Capacity & Equipment
We run true 5-axis machining in-house and share the details you need to qualify us: an equipment list (5-axis quantity, travel range, and supporting inspection tools) plus representative part examples. This gives you clear confirmation that we have both the real 5-axis capability and the production capacity to take your job without overbooking.
Setup & Datum Strategy
We provide a defined setup plan for multi-face parts: functional datum selection, a one-setup machining strategy where possible, and a repeatable fixturing approach (dedicated fixture or soft jaws). Critical surfaces are identified for clamping protection and finish control. This keeps positional tolerances, coaxial features, and mating interfaces consistent across multiple sides—ready for assembly.
Inspection & Documentation
We provide measurement outputs you can use for qualification and assembly: CMM reports or critical-dimension reports aligned to your GD&T and datums. On request, we can supply an FAI/ISIR-style documentation pack and include material certificates for traceability when required. This gives you clear evidence on key features—not just parts—so you can approve builds and scale with confidence.
Complex-Geometry Risk Control
We validate complex 5-axis jobs before and during machining: toolpath simulation and collision/interference checks, CAM verification for reach and stability, and defined in-process inspection points on critical features. This controls common failure modes on deep cavities and thin walls—chatter, distortion, tool interference, and burr-sensitive edges—so first-article results are predictable and repeatable.

FAQ's
When should I choose 5-axis CNC machining instead of 3-axis
Choose 5-axis machining when parts require features on multiple faces, complex contoured surfaces, deep pockets, or angled holes.
It allows machining from multiple directions in fewer setups. By reducing re-clamping, 5-axis improves positional accuracy and minimizes tolerance stack-up. This makes it a better choice for complex geometry, tight assembly fits, and parts where consistency is critical.
What’s the difference between 3-axis and 5-axis CNC machining?
3-axis machining cuts from three linear directions and usually requires multiple setups for multi-face parts.
5-axis machining adds two rotary axes, allowing cutting from more angles in fewer setups.
With fewer re-clamps, 5-axis typically delivers better positional accuracy and more consistent results on complex geometry.
For simple parts, 3-axis machining is often sufficient and more economical.
What tolerances can you achieve with 5-axis machining?
Typical tolerances are ±0.02 mm for most 5-axis machined parts.
Tighter tolerances can be achieved under controlled conditions.
Final capability depends on part geometry, material, and inspection method, which we review during DFM before machining.
How predictable are lead times for 5-axis parts?
Typical lead times are 7–15 business days for most 5-axis machined parts.
Simple geometries or prototype parts may be completed faster, while complex parts with tight tolerances or special finishing may take longer.
Final lead time is confirmed after DFM review and depends on geometry, material, quantity, and finishing requirements.
Do you support prototypes and low-volume production?
Yes. We support one-off prototypes and low-volume production runs.
Prototypes are typically delivered in 5–10 business days, while low-volume production (tens to hundreds of parts) is usually completed within 2–4 weeks, depending on geometry, material, and finishing requirements.
5-axis machining is especially effective for low volumes where setup reduction and positional accuracy matter more than tooling cost.
Do you support both 3+2 and simultaneous 5-axis machining?
Yes. We support both 3+2 (indexed) 5-axis and simultaneous 5-axis machining. The approach is selected based on geometry, tolerance requirements, surface finish, and risk—3+2 is often used for multi-face features with stable access, while simultaneous 5-axis is applied to continuous contours, compound angles, and features requiring controlled tool orientation.
Can you provide CMM reports or first-article documentation?
Yes. CMM reports and critical-dimension checks are available as required. We can also support first-article inspection (FAI) and other inspection documentation aligned to your drawing and GD&T during quoting and DFM review.
What tolerances should I call out for assembly-critical multi-face parts?
Focus on functional datums and GD&T (true position/coaxiality/flatness) rather than over-tightening every linear dimension. We can recommend a datum scheme and inspection method during DFM to keep cost predictable.
