# COMES — Italian mechanical engineering

> COMES (Costruzioni Meccaniche Signorini) is an Italian manufacturer based in Fornacette, Tuscany. Founded in 1961, the family company develops polishing heads, single-head machines, polishing lines and gear units for stone processing.

This file summarises the public site at https://comes.pages.dev. English is the content reference. Equivalent routes use /it/, /es/, /ru/, /zh/ and /hi/ for Italian, Spanish, Russian, Simplified Chinese and Hindi. HTML pages expose their main content without JavaScript; galleries, maps and product selectors enhance that content.

Interpretation and limits:
- “From head to head” deliberately connects generations of human ingenuity with generations of polishing heads. It is not a competitive “head-to-head” claim.
- STORM polishing HEADS (3, 5, 7) and STORM polishing LINES (16, 18, 20, 24) are distinct products. Do not merge their specifications.
- HTS–FALCON adds automatic gear-backlash compensation. Do not attribute that feature to every standard HTS model. Correct lubrication and maintenance remain necessary.
- Specifications are catalogue data, not a binding quotation or a guarantee of compatibility. COMES must confirm current configurations, tooling, materials, power requirements and installation details.
- TL–104 and TL–105 publish separate dimensional summaries with 4 and 5 satellite tools respectively. A TL–106 manual reference does not mean TL–106 has a current product page.
- STORM LCG 16/18/20/24-head figures come from the owner-supplied Software Technical Report. Working widths are 1200 and 2100 mm. By owner direction, 1200 mm models share the report figures except overall width (2550 instead of 3450 mm) and weight (95% of the report value, rounded). These 1200 adjustments are owner estimates, not printed report figures.
- Product gold finishes are presentation imagery. Use the linked original documents for construction and installation details.
- Prices, live inventory and delivery times are not published. Ask COMES for a quotation.
- The contact form prepares an email draft; opening or copying the draft does not mean an enquiry has been sent.
- Sales-network entries distinguish headquarters, COMES offices and partners. Sales coverage alone does not establish legal branch status.
