PRIVACY & LIMITATIONS
Gear inventory stays local. No lathe is controlled.
Leadscrew, target pitch/TPI, and gear tooth counts are searched only on the current page. ThreadTrain does not connect to lathes, motors, encoders, or CNC systems, and it never generates or sends machine instructions.
Theoretical speed ratio, not a lathe setup chart
The tool converts TPI to 25.4/TPI mm, searches A/B or (A/B)×(C/D) trains, respects repeated tooth counts as physical copies, and ranks absolute ppm before maximum gear and total teeth. Inventory is limited to 80 gears of 5–500 teeth each. It does not determine shaft positions, module/diametral pitch, pressure angle, mesh centers, idlers, direction, half-nut operation, machine rigidity, tooling, or cutting safety.
Lathe and inventory details may be private equipment data
Refreshing or closing discards inputs. CSV contains candidate A/B/C/D gears, theoretical ratio, pitch, TPI, ppm, and drift per 100 mm; reports and optional local checkpoints read the visible summary. Machine leadscrew specification, inventory, and production targets may be sensitive, so review them before sharing.
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.
← Back to toolLocal 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.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
