An End-user is manufacturing large drive shafts for mining equipment made out of alloy steel. They are using a Carlton Radial Arm drill with water soluble coolant using a rotary coolant adapter (RCA).
Previously, the customer was using a Guhring Cobalt Twist drill running at the following parameters: 190 RPM, 39 SFM, 0.003 IPR, and 0.57 IPM. The drill created a 10.0″ deep hole with a 0.7870″ diameter. The tool had a cycle time of 17 minutes, 33 seconds and a life of 10 holes. Seeking to improve their production, the customer wanted to reduce cycle time and decrease their cost of production.
AMEC recommended a GEN2 T-A® drill insert #451H-20 with holder #060602-101 running at the recommended parameters of: 190 RPM, 39 SFM, 0.008 IPR, and 1.52 IPM. The GEN2 T-A® tool lowered cycle time to an impressive 6 minutes, 35 seconds and increased tool life to 24 holes. The customer received a substantial cost savings of $7,084.67 or 62.6%.
Using the AMEC GEN2 T-A® insert, the customer achieved their goal and reduced the machine’s cycle time. Additionally, the customer doubled tool life while reducing their cost of production. They received a total cost savings of 62.6%.
