Plunge Milling Plunge milling has been around for a long time and can be the most consistent form of high metal removal, especially on older machines incapable of operating at high feedrates. This consistency is a result of efficient toolpaths, as there is little wasted tool motion when compared to more common methods of machining [...]
There are 10 inherent benefits that a good shrink fit chuck can offer a mold shop:1. Unsurpassed accuracyA properly produced shrink fit chuck should be able to guarantee 0.00012″ (3 microns) maximum run-out at three times the cutting tool diameter. This accuracy is very repeatable from operator to operator. […]
