Overview
Pearson Manufacturing delivers high-precision manual lathe services for round parts with exact dimensions and clean finishes. Depending on schedule and complexity, work may be coordinated under Pearson QA through our internal team or trusted Canadian partners. From prototype shafts and custom fittings to accurate reworks, we focus on consistency, fit, and function.
⚠️ Hybrid fulfillment: Not all lathe services are performed at our facility. We act as your sourcing and fulfillment partner to meet cost, capacity, and schedule.
Quick Specs
| Engagement | Best For | Speed | Notes |
|---|---|---|---|
| One-Off / Repair | Worn shafts, bushings, pins | Fast | Reverse-engineer from sample; restore fits/threads |
| New Part / Prototype | Custom shafts & fittings | Fast | Minimal setup; quick DFM feedback |
| Small-Batch | Short runs with repeatability | Medium | Consistent tooling, in-process checks |
| Threading & Tapers | UNC/metric, NPT, Acme | Fast | Relief grooves, gauge-verified classes/fit |
Common Materials
- Aluminum: 6061-T6, 7075-T6
- Steels: 1018, 1045, 4140 (HT by spec)
- Stainless: 303, 304, 316/316L
- Brass/Bronze: C360, C932
- Plastics: Acetal (Delrin/POM), Nylon, UHMW
Typical Lathe Capabilities
- Custom shafts, rods, pins, and bushings (new or rework)
- Precision external & internal threading (UNC/UNF, metric, NPT/BSPT, Acme)
- Boring, facing, grooving, parting, and precise shoulders/steps
- Close-fit diameters and press-fit features with targeted tolerances
- Tapers (MT/JT), chamfers, fillets, undercuts, and relief features
- Finishing & polishing on turned surfaces; basic knurling on request
Design for Manufacturability (DFM)
- Add relief/undercuts at shoulders and thread runouts to achieve clean seats and full thread depth.
- Specify thread standard/class (e.g., 3A/2A, 6g/6H) and gauge method (GO/NO-GO) for verification.
- Call out only CTQ diameters for tight tolerances; allow standard fits elsewhere to control cost.
- Use generous fillets/radii at diameter transitions to improve strength and finish.
- For long, slender parts, note straightness/runout limits and support strategy (centers/steady rest).
- Define surface finish on bearing/seal areas (e.g., ≤ Ra 1.6 µm) and allow cosmetic finishes elsewhere.
We’ll review CTQs, thread classes, and finish targets to confirm achievable specs before kickoff.

Manual Lathe FAQs
What materials can you turn?
Commonly aluminum, carbon/stainless steels, brass/bronze, copper, and engineering plastics (Acetal/Delrin®, Nylon, UHMW). Ask about your specific alloy/polymer.
What tolerances can you hold?
As a starting point: metals ±0.001″ on critical diameters; plastics typically ±0.002–0.005″ due to thermal/mechanical behavior. Tighter bands may be achievable after review.
Which thread forms can you cut?
UNC/UNF, ISO metric coarse/fine, NPT/NPTF, BSPP/BSPT, and Acme/Trapezoidal. Left-hand and multi-start threads available by review. We verify with calibrated thread gauges when specified.
Can you match a worn shaft without a drawing?
Yes. Send photos and basic dimensions. We can measure the sample, recreate the critical fits/threads, and produce a drawing for your approval. Start your lathe work quote — include overall length, diameters, thread spec, material, and finish targets.
What surface finish can I expect?
Typical turned finish is around Ra 1.6–3.2 µm (≈63–125 µin). Finer finishes are possible with polishing or post-process grinding where required.
