The Challenge
The customer is a mold maker for the plastics industry that contacted Allied to test BTA tooling. The workpiece is a 21” (533.4 mm) thick test block made of P20 material (28-32 Rc). They are using a Schienke Gundrill machine with Hulcut 745D semi-synthetic coolant (10% concentrate) at 1000 PSI (69 bar).
