When Does a Part Need 5-Axis?

If your part features complex free-form surfaces, multi-face machining requirements, undercut internal cavities, or would require 4+ setups on a 3-axis machine — 5-axis is the answer.

Complex free-form surfaces — turbine blades, impellers, sculptural geometries

Multi-face machining — parts requiring 5 or more feature surfaces

Undercut internal cavities — unreachable without angled approaches

Highly angled holes — beyond the capability of standard drill and tap

Tight inter-feature tolerances — where setup repositioning introduces cumulative error

Compressed timelines — multiple features, one operation, faster delivery

KING TOOL's engineers assess the optimal process route upon receiving your drawings. Five-axis machining isn't always more expensive; it's often the faster, more accurate choice.

Our 5-Axis Capabilities

True 5-Axis

Our 5-axis centers handle all features in one setup — milling, drilling, tapping, and angled holes. No repositioning means higher accuracy and better repeatability for complex components.

Programming

Our team designs collision-free toolpaths and optimizes tool orientation. All complex geometries are simulated offline, ensuring your first parts are right the first time.

DFM Review

We review your drawings upfront to identify risks, define the best process route, and confirm adjustments. First articles are CMM-inspected, and every part ships with a full dimensional report.

Surface Finishing Options

We provide a range of surface finishing techniques to improve the appearance, durability, and performance of your CNC 5-axis machined components.

Milling

Traditional milling processes can be used for surface finishing, achieving smooth surfaces with varying finishes depending on the tool used.
Polishing

This is a high-quality finishing process that smooths the surface, removing any scratches or marks left by previous machining steps. Polishing can achieve a mirror-like finish.
Grinding

A fine grinding process is used to smooth and refine surfaces, particularly when high precision and smoothness are required. It is ideal for harder materials.
Bead Blasting

Bead blasting involves shooting fine beads (typically glass or ceramic) onto the surface, creating a matte, uniform finish, and improving surface texture for better adhesion or coating.
Anodizing

For aluminum parts, anodizing is often used not only for surface protection but also to create a decorative finish. It enhances corrosion resistance and can introduce colors.
Electropolishing

This is a process that removes material from a metal surface through an electrochemical reaction, resulting in a shiny, smooth surface ideal for corrosion resistance and aesthetic appeal.
Deburring

Removing any burrs or sharp edges left on the part after machining. This process ensures smooth edges and a safer, more visually appealing finish.
Coating

Various coatings, like powder coating, can be applied to improve surface finish, add a protective layer, or provide specific aesthetic qualities. It’s often used on metal parts.
Lapping

A process where parts are polished using a soft abrasive slurry to achieve extremely fine finishes, often used for precision optical or mechanical components.

Tolerance Guide

Precision is critical in CNC 5-axis machining. We define tolerances based on part function, material characteristics, and manufacturing feasibility to ensure optimal performance and cost balance.

Proper tolerance design helps reduce machining cost and improve production efficiency:

Avoid over-tight tolerances where not functionally required
Use standard tolerances for non-critical features
Simplify complex geometries when possible
Maintain uniform wall thickness for better stability
Consider material behavior during machining

Tolerance Type	Standard Tolerance (±mm)	Material	Cost Impact	Machining Feasibility
Non-critical Linear Dimensions	± 0.05	Aluminum (6061, 7075)	Medium	Easy to machine with standard tools, suitable for complex geometries
Critical Linear Dimensions	± 0.02 - 0.05	Stainless Steel (304, 316)	Medium/High	Requires precision tools, machining is more complex due to material hardness
High-precision Linear	± 0.02 / 0.03	Titanium (Ti)	High	Requires 5-axis machining and CMM inspection, specialized tooling required
Non-critical Linear Dimensions	± 0.05	Brass	Low	Easy to machine, good for detailed parts with intricate features
Non-critical Linear Dimensions	± 0.05	PEEK, Delrin (POM), Polycarbonate (PC), PTFE (Teflon)	Medium	Good for high-performance, complex parts; require specialized tooling for smooth finishes
Non-critical Linear Dimensions	± 0.10	Copper / Brass	Medium	Ideal for electrical components, relatively easy to machine
