Choose the right process

3-axis vs 4-axis vs 5-axis milling

The right axis configuration balances production speed, part complexity, setup count, and unit cost.

01 Cost efficient

3-axis milling

Best for prismatic parts, housings, plates, and brackets that can be machined from a single orientation or with simple indexing.

  • Simple setups and fast throughput
  • Ideal for accessible pockets and faces
02 Multi-face

4-axis milling

Adds a rotary axis for shafts, bushings, and radial patterns. Multiple sides can be reached without repeated manual fixture changes.

  • Fewer manual setups
  • Efficient radial and indexed features
03 Complex geometry

5-axis milling

Simultaneous 5-axis machining produces organic surfaces and multi-face parts in a single setup, reducing lead time and cumulative fixture error.

  • Deep access and angled surfaces
  • Lower risk of setup-to-setup variation

Part geometry

Designed for difficult milling features

From deep pockets to fine hole patterns, our process planning matches tooling, workholding, and axis motion to the geometry of your part.

01

Deep cavities

High-speed milling with long-reach tooling for deep pocket and cavity features.

DFM guidance

Reduce milling cost before production

Standardize hole sizes+

Use standard drill and reamer sizes to avoid custom tooling costs.

Use practical internal radii+

Radiused internal corners allow larger, more rigid end mills than sharp 90-degree corners.

Limit depth-to-width ratios+

Deep, narrow slots increase cycle time and tool-breakage risk. Maintain reasonable ratios for pocketing.

Specify tight tolerances selectively+

Only require tight tolerances where necessary. Over-tolerancing increases inspection time and scrap risk.

Quality assurance

Inspection that supports production confidence

Every production run is backed by rigorous inspection protocols and documented process control.

CMM verification

Full dimensional verification for critical part features.

Optical measurement

Inspection support for intricate and difficult-to-reach features.

Calibrated tools

Height gauges, micrometers, and bore gauges.

Traceability

Batch traceability and material certifications available on request.
