Retooling and Maintenance
Why Sigma
- Retooling engineered for capability + takt, not “make it run”
- Strong fitment study: machine envelope, rigidity, coolant, gauging
- Tool + fixture upgrades that remove drift, chatter, and burr issues
- Maintenance discipline that prevents repeat breakdowns
- Fast ramp support with on-floor stabilisation
- Acceptance criteria and buyoff packs that teams can rely on
- Spares and PM planning tied to criticality and uptime
- Proven approach on retooling for engine/transmission families
Where Sigma Fits In
Need New Parts on Machines You Already Own?
Recurring Issues from Worn Fixtures/Tools?
Relaunch Stable Output on Existing Assets
Fitment Study (Machine vs Part Reality)
Scope: Capability gap, reach/clearance, rigidity, coolant and gauging alignment.
Deliverables: fitment report, feasibility notes, risk register.
Process Refresh & Workflow Re-shape
Scope: Operation sequence, machine split, takt alignment, setup strategy.
Deliverables: revised process plan, cycle-time study, acceptance criteria.
Tooling Upgrade / Re-engineering
Scope: New tools, combination concepts, step reduction, chip control.
Deliverables: updated tool list, tool specs, parameter windows.
Fixture Reconditioning & Robustness Upgrades
Scope: Restore datums, clamps, locators; improve repeatability and ergonomics.
Deliverables: fixture restoration buyoff, drawings/updates, clamping principles.
Preventive Maintenance & Spares Planning
Scope: PM frequency, inspection points, min-max spares, regrind loop.
Deliverables: PM checklist, spare list, tool/fixture health log format.
Re-validation & Ramp Support
Scope: Break-in, capability proving, stabilisation actions on floor.
Deliverables: capability study, handover notes, ramp stabilisation plan.
