Machining Challenging Metals
May 21, 2013
Thanks to tougher state and pending federal regulations, if you machine brass parts that will be used to deliver potable water you are either preparing to or already in the process of machining these parts from no-lead brass. Moreover, it’s expected that in the near future lead will no longer be used in any ferrous or non-ferrous alloys. So CNC machine shops that traditionally work with leaded brass face new challenges as they switch to unleaded material.
The reason lead has traditionally been added to brass is that, because of its softness and lubricating properties, it enables CNC machines to operate at higher spindle speeds. Therefore, machining no-lead brass can mean slower speeds and feeds plus higher material and perishable tool costs. All of which can increase cost-per-part by 50% or more. With this in mind, Gosiger applications specialists offer the following suggestions to reduce the cost of machining unleaded brass:
