GTA Grinding Services

Grinding cells that protect your tolerance stack-up

Cylindrical, centerless, and surface grinding envelopes sized for GTA production runs. We support blanket orders, maintenance rebuilds, and chrome workflows with inspection-ready documentation.

Cylindrical: 24″ Ø × 90″ Centerless: up to 4″ Surface: tables to 40″ Chrome coordination (NAHC)

Cylindrical grinding

24″ diameter × 90″ between centers with Zocca and Landis platforms, steady rests, and in-process gauging that hold taper and concentricity over long shafts.

Applications

  • Hydraulic cylinder rods and barrels
  • Power transmission shafts and rolls
  • Precision mandrels and tooling

Approach

Detailed setup sheets, stabilized wheel dressing, and certified inspection keep GTA production runs repeatable with minimal adjustment on install.

Centerless grinding

Through-feed and in-feed grinding up to 4″ diameter with documented blade changes and adaptive coolant plans that control heat on alloy steels during high-volume runs.

Capabilities

  • Through-feed and in-feed to 4″ OD
  • Profile grinding with dedicated tooling
  • Production cells with inline inspection

Value

We document wheel wear and blade settings to keep half-million piece programs consistent, integrating with Kanban or blanket order strategies.

Surface grinding

Flatness and finish programs for tooling plates, rails, and fixture surfaces with envelope capacity up to 40″, magnetic, or vacuum fixturing.

Scope

  • Magnetic and vacuum fixtures to 40″
  • Matched pairs with serialized size tracking
  • Surface finishes to Ra requirements

Quality

We align finish with coordinate measurement and provide certificates to match your internal quality documentation.

Chrome workflow (partnered with NAHC)

Chrome plating is managed through North American Hard Chrome, with Jameson Machining owning the grinding, masking instructions, and logistics plan.

What we handle

  • Pre-grind stock removal and concentricity
  • Masking and racking instructions for NAHC
  • Post-grind, polish, and inspection

Partner transparency

NAHC is our dedicated chrome partner. We maintain scheduling, logistics, and inspection so you have one accountable contact from start to finish.

Production run support

Release one-off jobs or half-million piece programs with confidence. We align tooling, work instructions, and logistics before the first grind so your team stays focused on assembly.

Launch planning

Process engineers receive review meetings, sample part approvals, and PPAP-style documentation tailored to your quality plan.

Inventory coordination

Blanket orders, Kanban pulls, and safety stock recommendations are tracked in our production calendar with proactive updates.

Rapid communication

Direct access via phone, WhatsApp, and email ensures tooling or drawing changes are implemented without pausing production.

Gear grinding & repair

Journal repair, flank dressing, and gearbox refurbishment with focus on fit and alignment.

Deliverables

  • Regrind bearing journals
  • Flank cleanups and backlash checks
  • Certified inspection reports

Next steps

Share your gearbox or gear drawing set and we will provide a refurbishment plan with risk notes before kickoff.
