Overview
Pearson Manufacturing coordinates precision grinding and honing for demanding flat, round, and bore features. Our team handles quoting details, DFM, fixture considerations, and inspection planning so finished parts meet your tolerance and surface requirements.
*Figures listed are guidelines. We’ll confirm achievable tolerance/finish after reviewing your CAD and print.
Quick Specs
| Process | Best For | Throughput | Notes |
|---|---|---|---|
| Surface Grinding | Flat plates, die faces, fixture bases | High | Excellent flatness/parallelism; crisp edges |
| OD Grinding | Shafts, journals, bearing surfaces | High | Roundness & concentricity control |
| ID Grinding | Precision bores, bushings, sleeves | Medium | Tight ID size/finish inside features |
| Centerless | Pins, small shafts, bar stock | Very High | High-throughput, uniform diameters |
| Honing | Final bore size & surface texture | Medium | Micro-finish & geometry correction (taper/bell) |
Grinding & Honing Capabilities
- Surface grinding with flatness/parallelism to ~±0.0002″ (by review)
- Cylindrical OD/ID grinding for shafts, bushings, sleeves, and housings
- Centerless grinding for pins, dowels, and small-diameter shafts
- Single- and multi-stone bore honing for precision size & finish
- Hard-part grinding (≈RC 60+) and post-heat-treat size correction
- Deburring, edge breaks, and polish finishing of ground faces
- Dimensional, roundness, and surface finish reporting (Ra/Rz)
Representative Equipment
- Precision surface grinders with magnetic chucks & rotary tables
- OD/ID grinding machines with in-process gauging (by routing)
- Centerless grinders for through-feed & in-feed ops
- Sunnen/Nagel-style honing systems with size control
- Coolant filtration & temperature control for stability
- Digital inspection: micrometers, bore gages, profilometers
Typical Applications
- Tooling plates, dies, and precision fixture bases
- Bearing journals and seal diameters on shafts
- Hydraulic valve sleeves, pistons, and precision bores
- Sealing faces, gasket surfaces, and wear plates
- Post-weld or post-heat-treat refinishing and correction
- Repair/restoration of worn cylindrical features
Grinding & Honing FAQs
How do I get a fast grinding/honing quote?
Upload STEP/IGES and a PDF with target sizes/tolerances, material & hardness (pre/post HT), surface finish (Ra), quantities, and any inspection/reporting needs. Photos with a ruler help for repairs.
Can you grind hardened parts and correct distortion after heat treat?
Yes — RC 60+ tool steels are common. We can bring features back to size and geometry after HT; include pre/post-HT dims and finish targets.
What tolerances and finishes are realistic?
Surface to ~±0.0002″ flat/parallel; OD/ID to ~±0.0002″ typical; honing to ~±0.0001–0.0002″ with ~4–8 µin Ra, subject to geometry and setup.
How is work coordinated?
We handle quoting details, DFM, routing, QA, and logistics under a single Pearson-managed workflow.
Do you provide inspection reports and surface readings?
Yes. We can include CoC, FAI/FAIR, bore size charts, and profilometer Ra readings. Note your QA plan on the RFQ.
Can you restore worn shafts or bores?
Often, yes. Options may include chrome or metal spray + grind, sleeve + hone, or oversize/undersize with matched bushings. Send photos and baseline dimensions.
