Machines a wide range of heat resistant alloys
Unique material characteristics of JX1/JX3 allow them to machine difficult to cut materials such as high nickel / high cobalt / powdered metals / heat resistant alloys which have recently become more common in the market.

Chip formation comparison

Continuous chips are typical when machining heat resistant alloys but at higher cutting speeds the chips break easily.
