Gun Drilling

RET now offer gun-drilling, having drilled a 12mm hole, 436mm deep in aluminium alloy on one of our horizontal machining centres; all RET’s machining centres has through spindle coolant at 70 bar pressure. The gun drilling was part of the machining cycle; i.e. not a separate, special process, thereby reducing lead-time and cost.
