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 holderthan 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 shapemachining with inclination is possible by 3 axis machine. 3. Adopted 2 grades: PVD coated grade “JC8015” for general & moldsteel, stainless steel and cast iron. Cermet grade “CX75” for improving surface roughness.
