Kennametal Dimple Clamps for KB1340 Inserts

November 24, 2010 / By The Chronicle
KB1340 is a superior market-leading grade to machine cast iron. To further improve the performance, we have developed a dimple designed clamping to ensure the stability in the pocket.

  • CBN replaces Ceramics more and more. We want to participate in this change.
  • KB1340 is a market leading CBN grade in grey iron applications.
  • Dimple clamping ensures tight and rigid clamping. Fits in holders that use Ceramtec #718, #716 clamps
  • Strategic target market is brake-disk manufacturers worldwide.
  • Besides the standard portfolio, specials are available with short lead-time
  • and competitive pricing. Contact Engineered Solutions AENA – Latrobe for
  • price and lead-time.
  • Cladded clamps for extended lifetime are available on request.
Target Application
Used for machining of cast iron in roughing and finishing operations.

 

Target Markets
General Engineering, Durable Goods, Transportation.
Strategic target: Brake Disk Manufacturers

 

Features, Functions and Benefits

  • KB1340 provides a great combination of toughness and wear resistance, which leads to longer tool life at elevated speeds for higher productivity.
  • Dimple and clamp provide great rigidity to avoid any movement of the insert.
  • Dimple clamps fit Ceramtec holder which uses clamp# 718 or 716.

 

Application Recommendation

Vc: 800 – 1500 m/min

Certain melts of grey cast iron can exhibit poor machinability – by as much as two orders of magnitude.

Related to either insufficient ageing or composition.
