Overview
Pearson Manufacturing provides access to CNC milling and turning for industries that demand tight tolerances, reliable lead times, and clean finishes. Some jobs are machined in-house at our Ontario facility, while others are fulfilled through certified Canadian partners. We coordinate sourcing, QA, and delivery so your parts arrive ready for install.
⚠️ Hybrid fulfillment: Not all CNC services are performed at our facility. We act as your sourcing and fulfillment partner to meet cost, capacity, and schedule.
Quick Specs
| Process | Best For | Throughput | Notes |
|---|---|---|---|
| 3-Axis Milling | Prismatic parts, plates, pockets | High | Most cost-effective; best for standard features |
| 4-Axis Milling | Parts needing rotary ops | High | Fewer setups; improved feature alignment |
| Turning | Cylindrical parts, shafts, bushings | Very High | Excellent roundness & throughput |
| Mill-Turn (coordinated) | Mixed prismatic + round | High | Complex parts via partner routing |
Common Materials
- Aluminum: 6061-T6, 7075-T6
- Steels: 1018, 1045, 4140 (HT by spec)
- Stainless: 303, 304, 316/316L
- Plastics: Acetal (Delrin/POM), UHMW, Nylon, ABS, PC
Our CNC Machining Capabilities
- 3- and 4-axis vertical milling (slotting, pocketing, profiling, surfacing)
- CNC turning with live tooling for cross/axial features
- Threading: UNC/UNF & metric (tapped, thread-milled where appropriate)
- Precision boring, reaming, and interpolation for tight fits
- Workholding & process development for repeatable production
- Material sourcing or machining from customer-supplied stock
- Inspection reports and FAIR/FAI on request
- Post-machining finishing & light assembly coordinated end-to-end
Design for Manufacturability (DFM)
- Min wall thickness (guideline): ≈0.8 mm metals; ≈1.5 mm plastics (thinner possible with review).
- Use standard drill sizes & thread series (UNC/UNF/metric) for faster turnaround.
- Prefer generous fillets in deep pockets to reduce tool deflection and chatter.
- Call out critical datums and tolerances only where function requires—keep others at standard.
- For cosmetic faces, specify finish (e.g., 1.6–0.8 µm Ra) and break edges to avoid burrs.
- Provide STEP/IGES + PDF with tapped hole callouts; include thread depth & class when relevant.
Figures above are guidelines. We’ll review your drawing/CAD and confirm achievable specs with the best routing (in-house or partner) before kickoff.
Common Applications
- Precision housings, covers, plates, and brackets
- Shafts, bushings, spacers, and threaded adapters
- Jigs, fixtures, nest plates, and tooling details
- Functional prototypes and bridge-production lots
CNC Machining FAQs
Is CNC work done in-house?
Both. Some parts are machined at our Ontario facility; others are routed to trusted Canadian partners based on material, geometry, capacity, and lead time. All work is coordinated under Pearson QA.
What tolerances can you hold?
Standard commercial tolerances are typically ±0.005″ for metals and ±0.010″ for plastics. Tighter tolerances (e.g., ~±0.001″) may be achievable after engineering review of geometry, process, and inspection plan.
Which materials do you support?
Common: 6061, 7075, 1018, 4140, 303/304/316 stainless, and plastics like Acetal (Delrin/POM), UHMW, Nylon, ABS, and PC. Others available on request.
Do you handle finishing and assembly?
Yes. We coordinate anodize, chem-film, passivation, powder coat, and light assembly so parts arrive line-ready.
What files do you accept?
STEP/IGES preferred for geometry; PDF for dimensions, tolerances, threads, finishes, and special notes.
