Tooling by DIJET QM MAX MQTTYPE High precision QM MAX BARREL TOOL Tuff Modular Heads System 1. High precision QM Max MQT type improved balance of holder than conventional holders. Possible to adapt multi-machining machines such as 5 axis machines. Lineded up high precision H grade inserts. High efficient machining is possible by adapting malti-blades specification. ➡ Accuracy of tool dia. with master inserts −0.02 mm 〜 −0.05mm (XPHW/T tType inserts) 2. Lineuped holders with cutting edge angle 3°, 5°. Complex shape machining with inclination is possible by 3 axis machine. 3. Adopted 2 grades: PVD coated grade “JC8015” for general & mold steel, stainless steel and cast iron. Cermet grade “CX75” for improving surface roughness.
