HRMDouble

  • HRMD is more economical due to the use of 6 cutting edges compared to HRM tool with a 3 edge positive insert.
Features
  • HRMD is more economical due to the use of 6 cutting edges compared to HRM tool with a 3 edge positive insert.
  • High rake angle cutting edge and chip breaker reduces cutting load.
  • Negative geometry has been designed for rigidity of cutting edge and double sided function.
  • Simple screw on system and stable support achieves strong clamping force.
  • Unique insert design for high feed and multifunctional machining.
  • HRMD insert with symmetrical cutting edge is applicable for both R and L type machining.

Machining Example - I

Machining Example - I

Working condition

  • Work piece SM45C(HRC22)
  • Cutting speed vc = 283m/min (1,803-1)
    fz = 1.4mm/tooth
    vf = 10,097mm/min
    ap = 0.8mm
    ae = 35mm
    Coolant : Dry
    Machining: Copying
    Machine : Horizontal MCT
    Overhang of tool : 250mm
  • Tool information SHRMDCM13050HR-4
    WNMX130520ZNN-MM(PC3500)
  • Productivity : 40% increased Tool cost : 80% decreased
Test result
In comparing HRMD with our competitor using the same cutting conditions, the cutting speed of HRMD was
higher with the same depth of cut (ap*ae), the cycle time was reduced by 40% and the tool life was
increased to over 60%. HRMD is economically more efficient due to the use of 6 cutting edges compared to
EDNW type with positive insert

Machining Example - II

Working condition

  • Work piece STS304
  • Cutting speed vc = 130m/min (414-1)
    fz = 1.2mm/tooth
    vf = 2.981mm/min
    ap = 1.0mm
    ae = 80mm
    Coolant : Wet
    Machining : Facing and Slotting
    Machine : Vertical MCT
    Overhang of tool : 250mm
  • Tool information HRMDCM13100HR-6
    WNMX130520ZNN-MM(PC3500)
  • Productivity : 80% increased Tool cost : 25% decreased
Test result
In comparing HRMD with our competitor using the same cutting conditions,the cutting speed of HRMD was
higher with the same depth of cut (ap*ae), the cycle time was reduced by 80% and the tool life was same,
but HRMD is economically more efficient due to the use of 6 cutting edges compared to SDKN type with
positive insert
