On-Card Flat Grinding Machine

An on-card flat grinding machine grinds flat tops in their working position on the card, restoring tip geometry without stripping flats to a bench grinder. Used with discipline, it keeps the flat-to-cylinder interface consistent. Used as a substitute for diagnosing carding problems, frequent grinding removes wire life while the real cause continues — so we supply the machine together with clear guidance on when grinding is, and is not, the correct response.

What we supply

  • On-card flat grinding machine (card flat grinding attachment)
  • Commissioning and operator instruction at installation
  • Guidance on grinding intervals aligned to wire life and quality data

Application area

Carding sections maintaining their own flat tops across the card population. Suited to mills that track carding quality data and want controlled, in-position correction of flat tip geometry rather than routine off-card grinding.

What Vaamana checks before supply

  • Compatibility with the card models on which the machine will be used
  • Traverse and grinding-element condition before dispatch
  • Setting repeatability — the machine must reproduce depth settings reliably
  • Completeness of guards and operating instructions

Information required from the mill

  • Card models and count in the section
  • Current flat grinding practice (off-card, service provider, none)
  • Wire/clothing life currently achieved and grinding frequency
  • Who will operate the machine and their training level

Common failure symptoms

Mills usually reach this page while investigating one of the following. If any of these match, mention it in your enquiry — it changes what we check first.

  • Flat tops with rounded or uneven tips across the width
  • Quality recovering briefly after each grind, then degrading fast
  • Inconsistent flat condition between cards in the same section
  • Grinding done on calendar schedule with no measurement backing

Frequently asked questions

Does on-card grinding replace off-card flat grinding entirely?

For routine tip maintenance, largely yes. Heavily damaged or worn-out flats still need reclothing or specialist correction; on-card grinding maintains geometry, it does not rebuild lost wire height.

How often should flats be ground?

By evidence — nep levels, flat condition and web quality — not by calendar. Frequent grinding without diagnosis shortens clothing life while masking the underlying cause. We provide an interval framework at commissioning.
