When you are rough machining cylinder bore, using DU406 tungsten carbide combination machine, this machine boring bar has 700mm length, during use, due to wear and often tungsten carbide boring tool to remove the body, dressing new cutter body, thus making threaded arbor often damaged, leading to the arbor can not be used. Since Arbor relatively heavy, frequent uninstall when workers stick, easy bruising machine.
To this end, we designed a tungsten carbide deep rugged back boring tool that adds a disk access. Lower end of the shank is processed into short Morse cone and convex milling slots, then set the upper groove milling and the cone, and Arbor docking. When removing the blade mounted on the connecting thread damage the lower disk access time, disk access as long as the new ones, tighten the screws on both sides of the disk on it, saving time and effort. Rose arbor nut is to prevent the blade will not fall short cone from the centering effect, punch trough power transmission, then the center of the plate with holes, air emissions.
After all the boring bar are transformed into tungsten carbide combination boring bar, it will achieve cost savings, and very easy to replace.
