HELLMERICH arbor milling heads are used, among other things, for machining crankshaft housings. Milling tools are usually lined up on a robust, multi-supported shaft. Different tool geometries are dealt with special designs.
When you are conducting heavy-duty metal cutting tasks as part of lathe and milling applications, machining units need to be highly durable, robust, and insusceptible to contamination. That is why great care was taken to ensure maximum spindle rigidity when designing the mechanics and thermics of Hellmerich’s drive spindles. Their maintenance-free air-tight seals ensure the units are hermetically sealed against contamination entering from the room in which you are using your machining unit.
