Machining center spindles: What you need to know
When you start to research spindle technology, you find the bearing system is often at the centre of the discussion. It can get mind-boggling, especially with the acronyms flowing freely—dN value benchmarks and formulas; O or DB mounting versus DF or X configuration; ABEC standards, and so on. An overview of key considerations when researching a CNC machining centre's bearing system covers the highlights—material, type, arrangement and lubrication.

Electrochemical machining an alternative to metal cutting
Electrochemical metal machining (ECM) is an established technique for burr removal. However, ECM can do much more. The EMAG ECM Company wants to use the process to replace conventional drilling, broaching and even milling. A number of advantages over machining speak in favor of this. The advance of electromobility alone will reduce the total number of parts required in the long term. In addition, components would look different in the future. More...
