Design

More Rigid and Less Vibration

By eliminating the shank connection between the tool holder and the indexable end mill, the modular head is more rigid and introduce less vibration during milling process, leaving better workpiece surface finished.

Start to Finish

We optimize our process for both efficiency and accuracy by utilizing Kawasaki robotic arms to load and unload bar stock into the Mazak multi-tasking machine centers. We use SCM420 alloy steel to lay the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper. We precision grind the internal bore surface to < .0002 " TIR and all bores are ground on a CNC grinder to ensure close run-out tolerance and evenly contact between the collet and the bore pocket. We use Haimer laser balancing machines to deliver a tool that can operate flawlessly at 20000 RPM and Mitutoyo or Mahr indicators to check the run out.

Spotlight

  • This tool holder accepts all threaded screw-in indexable mililng cutter which are often called modular indexable tooling, screw in or threaded shank cutter
  • Precision ground flat on the shoulder and internal pilot diameter that will self center the threaded indexable cutter
  • By accepting right-hand thread cutter into the tool holder, apply cutting force onto the cutter would increase the bond between the cutter and the tool holder
  • Runout is less than .0001" from taper to pilot bore
  • Made from alloy steel hardened to 54-60 HRc

  • Modular milling cutter head is able to cover variety of milling operation in die and mold manufacturing, automobile manufacturing, energy and wind power, and aerospace industry
  • Reduce inventory by only replacing cutter heads and not shank, other style of cutter body with different insert is also available
  • Feature precision ground surface on the locating shoulder and pilot outside diameter to ensure rigid contact with the threaded tool holder

  • Indexable cutter head threads into the tool holder by means of a right hand thread, any cutting force would only increase the bond between tool holder and cutter head
  • Reduces vibration on long overhang applications
  • Chip thinning effect allows for increased table feeds
  • High Positive cutting geometry 
  • Fitted with 10 degree positive rectangular inserts allow high depth of cut and feed per tooth
  • Use APKT / APHT / APET / APMT 11T308 insert (sold separately)
  • Setting Angle: 90 degree
  • Radial rake angle: -10 degree
  • Axial rake angle: 7 degree
