What is Basic Study of High Speed Micro Deep Drilling about?
Nomenclature I K. lwata (2). T. Moriwaki, Kobe University, Kobe/Japan -Submitted by T. Hoshi (1) I1 x 2 ## Spindle Spindle Summary : Experimental studies on high speed micro drillingdownto 0.1 mm in diameter have been carried out. Two types of drilling machines were manufactured for this purpose, in one of which the workbiece was fixed vertically to the table, and in the other relative rotary motions were applied in horizontal direction to both tool and workpiece. driven by air turbines. The maximum rotational speeds of the spindles are 180000 rpm for the tool side and 50000 rpm for the workpiece side. The feed motion is controlled by a microprocessor via a stepping motor. The paper describes the outlines of structures and accuracies of the drilling machines used. The torque and the thrust were measured employing a quartz-type piezo-electric load washer when drilling free machining stainless steels and brass with twist drills made of carbide K10 and high speed steel. The tool wear was measured and optimum cutting conditions were obtained for a given range of rotational speed and feed rate. The drilled holes were observed employing optical microscope and SEH. The influence of cuttin
