摘要： PURPOSE:To prevent the breakage of a cutting edge by measuring the protruding quantity of the cutting edge without touching the cutting edge. CONSTITUTION:The head 3 of a measuring device 1 is provided with an optical measuring means 22 to nontouchingly measure the protruding quantity of a cutting edge 30 on the image formation position of reflected light and a photographing camera 23 to photograph the cutting edge 30 including an optical measuring point A. The measurement value of the protruding quantity obtained by the optical measuring means 22 is displayed in a measurement value display section 5, and a photographed image is displayed by a video-monitoring device 4. The measuring point A is moved and regulated by a lower and an upper table 9, 12 so that it may be positioned at the top of the cutting edge 30. The protruding quantity of the cutting edge 30 is read by confirming the measuring point being at the top of the cutting edge 30 through observation on the video- monitoring device 4, and the protruding position of the cutting edge is thereby regulated.

摘要： PROBLEM TO BE SOLVED: To improve flow of chip to provided favorable discharge performance even when a chip discharging groove is narrow. SOLUTION: Same tips 18 are mounted in tip installation seats 16a, 16b inside and outside to a rotation axial line O on a pair of chip discharging grooves of a tip surface of a drill main body. The tip 18 is formed of a pair of outer blades 23 having a first and a second cutting blades 24, 25 provided through a step 23a, and a pair of inner blades 27 having a first and a second cutting blades 28, 29 provided through a step 27a. The outer blade 23 is positioned on the tip of the outer tip and the inner blade 27 is positioned on a tip of the inner tip 18, and the outer blade 23 is positioned on the tip side of the inner blade 20. Chip separated by the outer blade 23 and the inner blade 27 is thus generated.

摘要： PURPOSE:To improve stop position setting accuracy and duration of life and shorten control time by accommodating an input shaft rotatably in the feedback shaft of a servo valve rotated by the movement of a piston rod, and throttling the return oil flow by the angular deviation between both shafts. CONSTITUTION:A rack 49 is provided at the piston rod 31 of a hydraulic cylinder 32, and the feedback shaft 42 of a servo valve 37 is provided with a pinion gear 48 to be meshed with the feedback shaft 42, and also with first to third ports 57-59 connected to the ports a, b of the hydraulic cylinder 32 and a tank. An input shaft 43 is rotatably fitted into the feedback shaft 42. There are further provided a pressure passage 62 communicated with one of the first and second ports 57, 58 by the relative rotation of both shafts 42, 43, and a return groove 64, gradually changing its opening area, and communicated with the third port 59. Stop position setting accuracy and the duration of life are thereby improved, and control time is shortened.
