MMT High Production

Sunnen's MMT multi-stone mandrels provide superior speed and accuracy on applications using a variety of high-production machines, including the Sunnen KGM, ML and EC Series machines plus other major brands. These mandrels are perfect for bore diameters ranging from 3.8 to 31.7 mm (.150 in. to 1.250 in.) For sizes above 31.7 mm (1.250 in.) consult your Sunnen Field Engineer. Using MMT multi-stone mandrels can also save you money. Per-part honing costs can be reduced by 30 percent in some applications versus conventional honing tools.

FEATURES & BENEFITS

  • MMT tools last up to five times longer than conventional tools resulting in increased machine up time.
  • Using MMT tools can reduce honing cost-per-bore by 30% or more.
  • Engineered for high-volume, high-precision honing, MMT tools are ideal for applications such as fuel injector barrels, cartridge valves, pinion gears and gun barrels.
