  • MSRS90 more than doubled the machining efficiency compared with competitor B.
  • MSRS90 improved the machining efficiency to 1.3 times that of competitor C.
  • Competitor B machined with 2 passes (ap x ae=3 x 65mm).
  • Competitor C machined with ap x ae=5 x 50mm

MSRS90 machined with only 1 pass. Tool cost is reduced to 1/3 although competitor C is expensive using 2-corner insert.

Cutting time was reduced. (User evaluation) MSRS90 reduced machining cost as well as improved machining efficiency. (User evaluation)

  • MSRS90 more than doubled the machining efficiency compared with competitor D.
  • MSRS90 showed 1.5 times longer tool life than that of competitor E.
  • Competitor D machined with ap x ae=5 x 10~50mm
  • Competitor E machined with 2 passes on a side (ap x ae=12 x 0 to 10mm).
  • Low cutting force of MSRS90 enabled twice as large ap as that of competitor. Competitor E was poor in feed rate (Vf=400mm/min).

  • It can double the ap as well as increase the cutting speed (Vc=100 ➮150). improved by MSRS90 (by achieving reduction in cutting time).
  • Machining efficiency was improved by MSRS90 (by achieving reduction in cutting time). Although competitor E is load due to high cutting force. MSRS90 operates fairly quietly.
