Hardenability describes how deep a metal can be hardened upon quenching from high temperature, and can also be referred to as the […]

How Boring Bar Geometries Impact Cutting Operations

Boring is a turning operation that allows a machinist to make a pre-existing hole bigger through multiple iterations of internal boring. It has a number of advantages over traditional hole finishing methods: Solid carbide boring bars, such as those offered by Micro 100,  have a few standard dimensions that give the tool basic functionality in […]

Workholding Styles & Considerations

Machinists have a number of variables to consider when setting up devices for a machining operation. When it comes to cnc workholding, there are some major differences between holding a loosely toleranced duplicate part with a 10-minute cycle time and holding a tightly toleranced specialized part with a 10-hour cycle time. Determining which method works […]
