The end-user is machining a 41L40 sleeve bearing on a Daewoo Lynx 200L lathe with 100 PSI through-tool coolant.
Previously the customer was using a Guhring RT 800 WP high penetration drill running at the following parameters: 550 RPM, 0.005 IPR (0,13 mm/min), resulting in 2.75 IPM ( 69,85 mm). They were drilling a 1.201" (30,50 mm) diameter hole to a depth of 3.82" (97,03 mm). Total drilling time to complete 100 holes was 139 minutes, with a tool life of 382 total inches.
Before committing to repurchasing the competitive carbide drill inserts, the customer asked what Allied could bring to the table.
Allied recommended the GEN3SYS® High Penetration Drilling System, using insert item 5C129H-30.5 and holder 60329S-125F. GEN3SYS®
was run at the following parameters: 715 RPM, 0.012 IPR (0,30 mm/rev) resulting in 8.58 IPM (217,9 mm/min). GEN3SYS® delivered a performance that exceeded the expectations of the customer by drilling 632 total inches in just 74 minutes.
GEN3SYS® exceeded the customer’s expectations by proving to be the clear choice over the competitive tool. Allied’s solution allowed for a 70% reduction in cycle time while obtaining 66% additional tool life. The Cost Per Hole fell from $2.98 to $1.08, which resulted in a cost savings of 63.7%!
