HIGH PRECISION UNBALANCE REAMER EFFICIENTLY CUTTING BORE OF WORK PIECE IN MACHINING CENTER

摘要

PURPOSE: A high precision unbalance reamer is provided to improve the surface roughness, the roundness or the perpendicularity and to extend the life span of the tool by cutting the bore efficiently and accurately with a first end mill, a second guide and a third right-angled blade. CONSTITUTION: A high precision unbalance reamer of a machining center is composed of a guide part guiding in the bore for cutting the bore, a cutting blade part placed next to the guide part for cutting the bore, and an installation part mounted to a holder of the machining center. The cutting blade part of the high precision unbalance reamer is composed of a first end mill(60), a second guide(70) and a third right-angled reamer(80). Six blades are arranged at 90 angular degrees in the cutting blade part, and the bore of the part is cut according to the size of the part by using the unbalance blades.
