The Challenge
The customer is machining V35 vane pump rings made from 52100 using a Mazak vertical machining center with 1000 PSI through tool synthetic coolant.

Tool used:  KSEM drill with insert grade KC 7315 HP (M)
  • Hole diamater = 0.984" (25mm)
  • Hole depth = 2.5 inches (63.5mm)
  • 1200 RPM
  • 0.012 IPR (0.30 mm/rev)
  • 14.4 IPM (365.76 mm/min)
  • Cycle time = 10 seconds
  • Tool life = 40 holes
Looking for improvements, the customer asked Allied to provide a tool that would lower their cost per hole. The KSEM was $2.59 per hole due to poor tool life and sporadic catastrophic failures.
 
The Solution
Allied recommended the GEN2 T-A Drilling System.

Tool used:  GEN2 T-A insert (item 452H-25) and holder (item 22020S-125F)
  • 1200 RPM
  • 0.012 IPR (0.30 mm/rev)
  • 14.4 IPM (365.76 mm/min)
  • Cycle time = 10 seconds
  • Tool life = 104 holes
The large increase in tool life met the request by eliminating catastrophic failures during the entire operation.
 
The Advantages
The GEN2 T-A Drilling System made a significant difference for the customer
  • Increased tool life nearly 3x compared to the KSEM tool
  • Eliminated catastrophic failures
  • Reduced the cost-per-hole from $2.59 to $0.71
  • Total savings of 72.6%
