The positive geometry of Double Z inserts for the newly developed WSX series face-mills from MMC Hardmetal is said to produce low cutting resistance that makes the cutters suitable for all types of machines.
The moulded SNMU and SNGU G class type inserts used on the WSX cutter have all the attributes of a single-sided, positive geometry insert but, importantly, also have the advantage of being double-sided with eight cutting edges.
The cutting edges of the Double Z geometry inserts are set at a 17° positive axial rake angle when clamped. The WSX series features strong insert clamping and an anti-fly mechanism. According to MMC, 5 mm depth of cut is possible, while through-coolant holes are standard in cutters under 160 mm diameter.
WSX cutter bodies are available from 40 to 200 mm diameter in coarse, regular and fine pitch types.
