Turning, Grinding, and CMM Inspection

Turning, grinding, and CMM inspection at VisionForge are delivered through ISO 9001 partner operations — not in-house. We quote them as one coordinated package with in-house milling, so the customer gets a single RFQ, a single PO, and one accountable contact from drawing to ship. Partners are pre-qualified, audited, and treated as an extension of our quality system.

What's in-house and what's partner

Plain line for buyers. The site is transparent about where every operation happens:

  • In-house at VisionForge (Mississauga): 5-axis and 3-axis CNC milling, palletized lights-out production, vibratory finishing, first-article and in-process inspection.
  • Partner operations (ISO 9001): live-tool turning, precision grinding (surface and cylindrical), CMM inspection to ±0.0002" with certified reports.

Partner work runs under ISO 9001 quality systems. AS9100D in process at VisionForge is coordinated with the partner's quality processes at the lot level — material certifications, FAI data, and PPAP submissions flow through one file, not three. See Quality & Certifications for the governing statement.

Live-tool turning

Turned parts, from simple bar-fed shafts to live-tool work that combines turning and milling on a single spindle. Routed to a long-standing ISO 9001 partner when a job calls for it.

  • Materials: 6061-T6 and 7075-T6 aluminum, 304, 316, 416, and 17-4 PH stainless, Ti-6Al-4V, brass, copper, tool steel
  • Capability range: small-diameter precision shafts through larger-diameter turned bodies with cross-drilled or milled features
  • Typical parts: shafts, pins, bushings, fittings, connectors, hydraulic components, turned aerospace details with milled flats or holes
  • Tolerances: ±0.0001" achievable on qualifying features; tighter tolerances in coordination with grinding
  • Material certifications: traceable to mill, provided at ship

When a part needs both turning and milling, we plan the sequence at quote so the part moves between stations with minimum handling and a controlled reference datum.

Precision grinding

Precision grinding — surface grinding and cylindrical grinding — is routed to ISO 9001 partners when drawing tolerances or surface finishes exceed what milling or turning can produce directly.

  • Surface grinding: flat and parallel faces, sealing surfaces, mating interfaces
  • Cylindrical grinding: OD and ID grinding on shafts, bores, and precision journals
  • Typical use cases: surfaces that must hold flatness or parallelism under the tolerance achievable on a mill, hardened-stock grinding after heat treat, ground sealing faces on hydraulic and fluid components
  • Tolerances: partner-grind tolerances down to the levels a certified grinding shop expects to hold; certified reports on request
  • Finish callouts: Ra values per drawing; partner verifies and documents

If heat treat sits between milling and grinding, we sequence the partner chain so the part doesn't lose its reference datum between operations.

CMM inspection to ±0.0002"

Final CMM inspection is routed to an ISO 9001 partner when a certified CMM report is required — typically on aerospace, defence, and medical parts with GD&T that specifies CMM verification.

  • Accuracy: ±0.0002" on critical features, certified report
  • Report formats: AS9102-format First Article reports, dimensional reports keyed to ballooned drawings
  • Data packages: actuals against nominal, probe file references, traceability to the operator and inspection date
  • Use cases: first-article inspection (FAI), PPAP submission packages, critical-to-function verification on production lots, receiving-inspection support for customers who re-run incoming CMM on our parts

Our in-house inspection is built around the critical-to-function list at part level; partner CMM is layered on when the program or the customer SQE requires an outside-certified report.

One RFQ, one PO, one accountable contact

  • One RFQ. Send the drawing once. We quote in-house milling, partner turning, grinding, and CMM inspection as a single line-item breakdown.
  • One PO. The customer issues the PO to VisionForge. We contract the partner work under our umbrella.
  • One accountable contact. Same person who quoted the job signs off the first article and owns the production record — across in-house and partner steps.
  • Coordinated schedule. We plan the partner chain at quote so no operation becomes the mystery bottleneck. Ship dates hold because the chain was sequenced before the PO landed.

The customer doesn't manage three vendors. VisionForge manages the chain and reports to the customer.

Quality system alignment

  • AS9100D in process at VisionForge. Aerospace customers who need AS9100D work with us under supplier-approval agreements during that process.
  • CGP registration under Government of Canada review. Designated Official exam passed. Controlled-goods programs can be discussed once registration confirms.
  • ISO 9001 partner operations for turning, grinding, and CMM. Partners are audited and requalified periodically.
  • Material traceability: heat number and certifications captured against every lot, regardless of which station did the work.
  • FAI and PPAP support: AS9102-format FAI reports on request; PPAP submission levels 1–5 supported, coordinated with the customer's SQE.

Typical programs that use partner ops

  • Aerospace turned and ground details with certified CMM reports
  • Hydraulic components requiring ground sealing surfaces
  • Defence program parts with FAI/PPAP documentation
  • Medical device parts where the drawing specifies certified CMM verification
  • Industrial components combining milled and turned features on the same body
  • Production releases where customer-spec receiving inspection requires a CMM data package on every lot

How to structure an RFQ that includes partner operations

  • Drawing(s) with GD&T, revision level, surface finish callouts
  • 3D model (STEP preferred)
  • Inspection requirement — certified CMM report? AS9102 FAI? PPAP level?
  • Heat-treat / grinding callouts — condition, sequence, and whether grinding is to drawing dimension or to a stock allowance on the milling step
  • Material certification requirements
  • Target lead time and release quantities

FAQ

Why are turning, grinding, and CMM inspection partner operations instead of in-house?

Those capabilities are delivered through ISO 9001 partners VisionForge has worked with long enough to treat as an extension of our quality system. Keeping them as audited partner operations — rather than building underutilised in-house capacity — keeps the pricing honest and the quality documentation strong. The customer still works with one VF contact; we manage the partner chain.

Do I have to contract the turning / grinding / CMM work separately?

No. VisionForge quotes the full path on a single RFQ and the customer issues a single PO to VF. We subcontract the partner work under our umbrella and ship the finished part.

What tolerances are achievable across the partner chain?

±0.0001" in-house on milled features. Turning tolerances in the same range on qualifying features. Grinding tolerances per the certified grinding partner's capability. CMM verification to ±0.0002" with a certified report. Tighter tolerances are quoted on review of the drawing.

Do you provide certified CMM reports on every lot?

Only when the drawing or customer requirement calls for one. Most production lots use in-house inspection on critical-to-function features with partner CMM layered in for FAI, PPAP, or customer-mandated receiving-inspection packages. Send the requirement at RFQ and we'll price it.

How do you handle material traceability through partner operations?

Heat number and mill certification stay attached to the lot at every station. VisionForge carries the material record through the partner chain. Certifications are delivered with the shipment and archived against the part record for the retention period the customer requires.

What's the lead-time impact of adding partner operations?

Sequenced at quote, not after. Partner scheduling is locked in before we quote the ship date, so adding grinding or certified CMM doesn't create a last-minute bottleneck. If a specific partner slot would extend the ship date, we call it out in the quote.

Is the partner work covered by VisionForge's quality system?

Partner operations run under the partner's ISO 9001 system; VisionForge's AS9100D-in-process quality processes coordinate the lot-level documentation. Material certs, FAI, and PPAP submissions flow through one coordinated file. We do not claim partner work is performed under AS9100D until VF is certified and the partner qualification is reassessed under that standard.

Where are you located, and where do the partners sit?

VisionForge is at 1578 Finfar Ct, Unit #2, Mississauga, Ontario. Our partners are Ontario-based unless a specific program requires otherwise. Partner locations and qualification status are disclosed on request under an NDA where applicable.
