Webinar: Increase Milling Output on Your Existing Machine
It is not always the strength of the tool or the power of the machine that limits your depth of cut. In many cases, the limitation is the tendency to vibrate. Learn how to mill more productively by selecting spindle speeds tailored to your machine’s...
Milling Hard-to-Machine Materials on a Micro Scale
The idea of a tool that effectively controls heat with a special grade of carbide, a new coating and internal channels that deliver cooling through ports in the shank where the milling flutes begin, is worth a look.
When to Waterjet, When to Mill
A composite parts manufacturer in Nebraska recently installed a combined five-axis waterjet/milling machine to position itself to win large-scale aerospace work it sees on the horizon.
Alter the Axial Depth
In difficult-to-machine metals, when a pocket or similar deep feature is milled in successively deeper Z-axis levels, oxidation and chemical reaction can affect the tool at the upper surface level of each cut. The solution: Change the axial depth of...
Anatomy of a High-Feed Insert
These tools exploit chip thinning to enable efficient roughing at high feed rates and light cutting depths.
65 Years in Business
To commemorate its 65th anniversary, Kaiser has opened a second building, co-located with its newly expanded headquarters.
Average Chip Thickness: What It Is and Why You Should Care
During milling applications, chips that are too thin might indicate inadequate heat dissipation that can cause premature insert wear. Too thick, and cutting forces might be high enough to break inserts outright. Cutting parameters should be set to a...
Comparing Apples to Apples
Consistency is key to properly evaluating the effect of any process change.
Watch for Opportunities to Test Tools
I often advocate evaluating new cutting tools, but finding the time and resources to do this testing is not easy.
Replacing Broaching with Milling
Trochoidal milling is a toolpath technique generally applied to increase tool life or material removal rate in hard metals. Manufacturing solutions provider Iruba also relies on this approach to make a shaped milling tool effective.
