Specification

Description

The TYROLIT STARTEC XPP+ product line represents a breakthrough in precision grinding for round tool manufacturing. Engineered for both cubic boron nitride (CBN) and diamond abrasives, STARTEC XPP+ wheels are optimized for fluting and gashing operations on HSS and tungsten carbide cutting tools. The advanced bond system and carefully designed wheel structure deliver measurable advantages: reduced grinding forces for improved process stability, or enhanced profile retention for extended dressing intervals and superior dimensional accuracy. Whether grinding carbide or steel, manufacturers can rely on STARTEC XPP+ for high stock removal, cooler cutting action, and consistently sharp edge geometry, raising productivity without sacrificing surface quality or tool precision.

Features

  • Innovative Metal Bond Structure—Engineered to balance sharpness, form stability, and wheel life, providing either lower cutting forces or higher profile retention depending on application needs.
  • Dual Abrasive Options (Diamond or CBN)—Diamond delivers unmatched efficiency on carbide, while CBN ensures precise results on HSS and other ferrous tool materials.
  • Straight Wheel Designs (1A1, 1V1)—Optimized geometries for CNC fluting and gashing operations, offering stability and access to complex tool profiles.
  • Cool Cutting Action—Minimizes thermal load on cutting tools, reducing risk of burning, edge chipping, or metallurgical damage.
  • Extended Wheel Life—Lower dressing frequency reduces downtime and consumable costs, improving overall productivity.

Application

Application

  • 1

    Fluting operations on solid carbide end mills for high precision cutting channels.

  • 2

    Gashing HSS and carbide drills to produce accurate point geometry and reliable chip evacuation.

  • 3

    Flute and relief grinding of reamers and step tools for demanding production environments.

Recommendations

  • Choose diamond for tungsten carbide and CBN for HSS to maximize grinding efficiency.
  • Use adequate coolant delivery directly at the grinding zone to control heat and improve tool finish.
  • Match bond hardness and grit size to the tool geometry and desired finish—coarse for heavy stock removal, fine for precision edges.
  • Dress wheels with proper tools and intervals to maintain sharpness and form integrity.
  • Operate within TYROLIT’s recommended speed and feed parameters for optimal results.
