How a Graphite Machining System Enables High-Accuracy Automotive Mold Electrode Machining

In automotive mold manufacturing, producing high-precision graphite electrodes for Electrical Discharge Machining (EDM) presents unique shop-floor challenges. Even straightforward mold designs often demand tight dimensional tolerances, flawless surface finishes, and repeatable accuracy across long production runs. One of our automotive mold clients continuously struggled with micro-chipping, thermal drift, and rapid tool wear while milling complex […]

Why Choose a Bullnose Endmill for Steel Machining Over Flat Endmills?

Last month, a long-time German client emailed us in frustration. He was machining a batch of 42CrMo4 pre-hardened steel mold bases, but his standard flat-bottom carbide endmills kept micro-chipping at the corners in less than 30 minutes. This caused nasty chatter marks across the workpiece and sent his per-part machining costs soaring due to constant
