Mitsubishi Materials U.S.A. Corporation (MMUS) products

A choice of different grades ideally suited to all types of cast iron machining. The process of casting iron enables complex geometries to be formed in the component that is produced. Different types of cast irons produce different chips when machined and can cause various types of damage to an insert. The complex shapes produced in castings also creates challenges when machining and can vary from continuous to interrupted cutting. In response to these challenges, Mitsubishi Materials has created a series of grades that are able to successfully machine all types of cast iron materials and component geometries.

Holder: Double clamping for secure retention. Insert: Maximum chip control through unique geometry.

The optimized “X-type” insert realizes stable and high-quality machining. The generous thickness of the insert provides high rigidity. The WWX200 insert is 1.5 times thicker, and the WWX400 is 2.2 times thicker than the conventional ASX400 insert, achieving high rigidity and excellent fracture resistance. In addition, the increased rigidity eliminates the need for a seat component as direct clamping provides stable insert fi xation.
