Cylinders: BT-A
Code
0902
The Challenge
The customer machines cylinders made from 1045 steel using a Technidrill BTA machine operating at 900 PSI (62 bar) with semi-synthetic coolant.
The Ingersoll tools had difficulty drilling a straight hole, and the customer produced few parts that had the drill actually come out the side of the cylinder.
The BT-A Drill delivered a much straighter hole with less than 0.010” (0.254 mm) variance in cylinder wall thickness.
