Overview
Pearson Manufacturing provides access to high‑precision surface grinding services through a hybrid fulfillment model. Whether completed at our Ontario‑based shop or coordinated through trusted Canadian partners, we deliver micron‑level tolerances and exceptional flatness for hardened components, tool steels, and critical mating surfaces.
⚠️ Hybrid fulfillment: not all jobs are ground on‑site — we leverage a mix of internal capability and trusted Canadian partners under Pearson QA.
Quick Specs
| Process | Best For | Speed | Notes |
|---|---|---|---|
| Reciprocating (Surface) | Tight flatness/finish on plates, blocks | Fast | Ideal for tool steels & hardened parts |
| Rotary (Blanchard) | Large plates where speed matters | Fast | Coarser pattern; follow with finish grind if needed |
| Double‑Disc | Parallel faces on production volumes | Medium | High throughput; great for spacers/shims |
| Lapping/Polishing | Ultra‑fine finishes/flatness | Medium | Specialty process; by review via partner network |
Surface Grinding Capabilities
- Flat grinding with tight flatness & parallelism control
- Surface finishes down to Ra 16 µin (finer by process)
- Magnetic chuck workholding & non‑ferrous fixturing
- Micron‑level dimensional accuracy and repeatability
- Grinding stock removal & finish passes optimized per alloy
- Documentation: in‑process checks & final inspection (as requested)
Supported Materials
We grind a wide variety of materials depending on project requirements and partner capability:
- Tool steels (D2, A2, O1, H13)
- Hardened alloy steels
- Stainless steels
- Carbide/PM steels (review for process/fixturing)
- Aluminum (with fixtures; wheel/process dependent)
- Copper/brass & specialty metals (by review)
Design for Manufacturability (DFM)
- Call out **flatness**, **parallelism**, and **finish (Ra)** targets separately; avoid over‑tightening all at once.
- Provide **grind stock** on faces (e.g., 0.005–0.015″ per side) to ensure cleanup after heat‑treat or machining.
- Add **relief grooves** or chamfers where feasible to reduce burrs and edge burn.
- Specify **critical datum faces** and match‑grind requirements for paired components.
- For non‑ferrous parts, confirm **fixturing** (vacuum/adhesive/soft jaws) and finish expectations.
We’ll review geometry, datum scheme, grind stock, and finish — and confirm achievable specs with the best routing (in‑house or partner) before kickoff.
Typical Applications
- Die & mold bases and parallels
- Tooling plates, hardened inserts & wear blocks
- Shims, spacers, blades & knives
- Gauge blocks, metrology components, setup masters
- Slideways, machine rails & alignment surfaces
- Final finish prep after machining or heat‑treat
Surface Grinding FAQs
What’s the difference between surface grinding and milling?
Grinding uses an abrasive wheel to achieve superior flatness, parallelism, and fine finishes; milling excels at bulk removal and contours. Many jobs use milling for roughing and grinding for final surfaces.
Can you hold tolerances under 0.001″?
Yes. We routinely hold ±0.0005″ on flat/parallel features; tighter limits may be achievable after review of geometry, material, and setup.
Is the grinding done at your facility?
Some work is done at our Ontario shop. Larger formats, specialty materials, or production volumes may be routed through certified Canadian partners under Pearson QA.
