Pick the Right Draw Cushions for Your Presses

摘要

This special function has to do with loading the draw cushion and is called "pre-loading the draw cushion." Loading the hydraulic cushion before the stroke ensures that the pre-set draw cushion force is available from the first millimeter of the draw travel as with a pneumatic draw cushion. In addition to the hydraulic and control technology involved, pre-loading also assumes stroke limitation function.
