DEB1000 (T-DIA Endmills) Specifications PCD Endmills Features Provide superior wear resistance and longer tool life in machining non-ferrous metals and non-metals compared with carbide endmills. Less tendency to develop a built-up edge allows to produce excellent and accurate surface finish. The center cutting edge allows plunging. Applications Aluminium alloys copper alloys and other non-ferrous metals Non-metals such as glass-fiber plastics epoxy resin carbon artificial marble and hard rubber. Cat.

Reduce number of revolutions and table feed in order to prevent chattering when the protrusion length is long. Use the machine with high rigidity. Adjust the number of revolutions and the table feed according to the situation of use (cutting depth or machine rigidity etc.) Practical examples Work material Aluminium alloy (AC4B-T6) SiC-whisker reinforced aluminium alloy Endmill DEB1060 (06 mm) DEB1100 (010 mm) Cutting speed Vc (m/min) 68 113 Feed f (mm t) 0.1 (360 mm/min) 0.05 (180 mm/min) Cutting depth ap (mm) 2 1 Cutting width ae (mm) 3 6 Results After machining for 20 min under above conditions both the surface finish and accuracy of the work were good. Surface roughness of Rmax 1.62 im was attained. After machining 12.6 m under above conditions the flank wear was VB 0.05 mm.
