Specification

Description

Cup type diamond grinding wheels, such as the 11V9 profile, are designed for the demanding requirements of round tool manufacturing from tungsten carbide and other nonferrous materials. Engineered with high-performance diamond abrasive and advanced bond systems, these wheels deliver unmatched sharpness, edge quality, and tool-to-tool consistency. Their cup geometry allows precise access to cutting edges and relief surfaces, making them the preferred choice for clearing, pointing, sharpening, and secondary relief operations. With excellent form retention, fast stock removal, and long service life, diamond cup wheels support efficient production and regrinding of cutting tools while reducing downtime and scrap.

Features

  • Diamond Abrasive Grain—Provides exceptional hardness and wear resistance, ensuring efficient grinding of carbide tools with minimal wheel wear.
  • Cup Type (11V9) Profile—Designed for access to tool relief areas and fine edge work, enabling accurate sharpening and secondary relief.
  • Resin and Hybrid Bond Systems—Tailored to balance aggressive stock removal with surface finish quality and long wheel life.
  • High Form Retention—Maintains wheel shape across multiple cycles, supporting consistent tool geometry.
  • Cool Cutting Action—Reduces thermal loading on carbide tools, minimizing risk of edge chipping or microcracking.

Application

Application

  • 1

    Pointing and sharpening of carbide drills to restore precise cutting edges.

  • 2

    Secondary relief grinding on carbide end mills for optimized clearance.

  • 3

    Clearing and edge preparation of reamers and rotary cutting tools made from tungsten carbide.

Recommendations

  • Ensure continuous coolant delivery to reduce heat buildup and protect cutting edges.
  • Match grit size to the operation—finer grits for sharpening/finishing, coarser grits for clearing and stock removal.
  • Dress wheels periodically to maintain sharp cutting action and precise cup geometry.
  • Follow recommended operating speeds to balance stock removal with wheel life.
  • Store wheels in a dry, temperature-stable environment to maintain bond integrity.
