Machining Services

Angled features, contoured surfaces and multi-face components need a machining plan built around the drawing. We review tool access, workholding and the dimensions that matter. Examples to review include multi-face mechanical parts and components used in robotic machining cells.

Choose the Machining Route for Your Geometry

Five-axis machining expands access to angled and multi-face features. Whether indexed or simultaneous motion is appropriate depends on the drawing, setup and available machine configuration.

POSITION. LOCK. MACHINE.

Reach an angled face. Then cut.

Two rotary axes position the part or tool. The orientation stays fixed while the three linear axes machine the feature.

Angled holes and mounting faces
Pockets approached from different directions
Prismatic parts with features on several sides

A practical route when each feature can be machined at a fixed tool orientation.

COORDINATED MOTION

Change orientation through the cut.

Linear and rotary axes move together during cutting to follow a surface or maintain a suitable tool approach.

Continuous contoured surfaces
Changing tool access along a feature
Geometry requiring coordinated rotary motion

The machining route depends on tool access, machine configuration, programming and the part requirements.

Use the process the part needs. If three-axis machining can meet the drawing efficiently, it may be the more practical route.

03 / ENGINEERING & QUALITY

From Drawing Review to Inspection.

Plan the datum scheme, workholding and tool access before machining; agree the inspection scope against the dimensions that control function.

01
Start With the Functional Geometry
Identify the datum system, mating surfaces, bore relationships and dimensions that control the assembly.
02
Plan Access and Workholding
Review tool reach, collision clearance, clamping surfaces and the sequence for features that cannot be reached in one setup.
03
Program, Simulate and Prove
Prepare the toolpath, check the machining sequence and inspect a first article before moving into the agreed production run.
04
Inspect the Features That Matter
Use the inspection methods agreed for the drawing. Check parts through production and complete final inspection before packing.

5-Axis CNC Machining FAQ

Answers to common engineering and sourcing questions.

What is the difference between 3+2 and simultaneous 5-axis machining?

In indexed 3+2 machining, the rotary axes position the part or tool and remain fixed while cutting takes place along the linear axes. In simultaneous 5-axis machining, linear and rotary axes move together during the cut. The appropriate route depends on the geometry, tool access and available machine configuration.

Can every surface be finished in one setup?

No. The fixture must hold the part, so clamped surfaces and inaccessible features can require another setup. The benefit is often fewer repositioning operations, rather than a guarantee that every part is completed in one setup.

Does five-axis machining automatically mean tighter tolerances?

No. Fewer setups can help preserve relationships between features, but accuracy also depends on the material, workholding, tool reach, thermal conditions and inspection method. We confirm tolerances feature by feature against your drawing.

When is 3-axis machining the better choice?

If the required features are accessible in practical setups and the drawing can be met, 3-axis machining may offer a simpler and more economical route. Five-axis machining is considered when added tool access or reduced repositioning provides a useful benefit.

Which materials and surface finishes can I request?

Send the exact material grade and condition with your drawing. Options include aluminum, stainless and alloy steels, titanium and engineering plastics. Finishes are selected for material compatibility and may include anodizing, hard anodizing, bead blasting, polishing, brushing, passivation, electroless nickel plating, zinc plating, powder coating or black oxide.

What information is needed for a five-axis machining quote?

Include a 3D model, dimensioned drawing, material grade, quantity, drawing revision, required finishes and delivery target. Identify critical tolerances, datums, cosmetic surfaces and the inspection documentation you need. The quotation confirms the machining route, achievable requirements and production schedule.
