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.
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
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
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

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.
