Mitsubishi Materials Insert grades for the WSX series
The positive geometry of the Double Z inserts for the WSX series takes face milling to a new level of usability with 8 cutting edges. The geometry also produces low cutting resistance, making it ideal for all types of machines, from low power through to heavy duty types. This level of cutting resistance is only usually associated with conventional single sided positive inserts and allows end users to increase machine utilization.
Three new insert grades have now been added to the range: MP7140, MP9130 and MX3020/3030. According to Mitsubishi Carbide, they are specially designed for stainless steels, HRSA and wiper finishing respectively and allow the WSX cutter to cover an extended application range. Although double sided, when set in the cutter body a 26º positive axial rake angle is produced. This provides a strong but sharp cutting edge whilst allowing the inserts to be double sided. Furthermore, a large 5mm max depth of cut is possible.
A predictable and safe performance is demanded by today's customers and the WSX series meets these criteria with strong insert clamping and an Anti–Fly mechanism. Through coolant holes are also standard in cutters under Ø160, providing efficient chip removal and cooling to further enhance process reliability.
Tough-Σ technology is used in the new MP range of insert coatings to provide enhanced heat and wear resistance and provide a low coefficient of friction, lending further help towards the ultimate aim of complete process reliability across a wide application range, the company says.
The inserts are equipped with a series of chip breakers specifically designed to cover a varied range of applications. L breaker has a positive land for lighter cutting and the lowest cutting resistance, M breaker is for general cutting and the R breaker has enhanced edge strength for rough cutting.
The cutter bodies are available in diameters from 40 to 200 in regular and fine and ultra fine pitch types. New standard pitch left handed cutters are now also availab from 80 to 160.
