Die workshop usually use three types of milling tool: solid carbide end mills, indexable carbide inserts and the latest development of indexable ceramic inserts. In different processing applications, these three tools have their own advantages and disadvantages.

(1) solid carbide end mills usually takes precision grinding and coating, its price is quite expensive. When the tool becomes dull and must be re-grinding and re-coating. However, after its restored mill cutting knife is often not as good as the new good.

(2) The second type of hard milling cutter equipped with indexable carbide inserts. In most cases, this type of blade inserts carbide grade and geometry is not designed for hard milling and design, so when machining hardened materials can not provide the best tool life and productivity.

(3) The third type of hard milling cutter with a ceramic indexable inserts, especially whisker reinforced ceramic inserts. Use with indexable ceramic blade cutter system can bring many benefits, including reducing the processing cycle and reduce each workpiece machining processes. However, the use of this tool requires programmers and system operators must rethink process, and should pay attention to some of the details may not be necessary to consider using other tools.
