PRIVACY & LIMITATIONS

Spring parameters stay local. No equipment is connected.

Geometry, material modulus, travel, and candidate wires are calculated only in the current browser. SpringTune connects to no test machine, CAD, inventory, or purchasing system and sends no manufacturing instructions.

Linear round-wire model, not production approval

The model does not provide allowable material stress, fatigue life, relaxation, buckling, end seating, preload, tolerances, finish, or dynamic-surge checks. Wahl stress is not an allowable value, and negative clearance means the geometry exceeds solid condition.

Candidates are not purchase specifications

The spring maker must review material, heat treatment, tolerances, and the full load cycle, followed by prototype testing.

Advertising and local preferences

This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.

Local report studio

The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.

Optional local checkpoints

Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
