Patent number: 7687739Abstract: A seal structure channels drainage of machining fluid from the periphery of an opening for a lower arm of a wire-cut electric discharge machine. The seal structure restricts flowage to the outside of machining fluid through the opening (slot) in a side of a machining tank and has a first seal and a second seal (a seal plate) affixed to the first seal so as to cover the opening. An unevenly shaped part including ridges and grooves extending in the long direction of the first seal is formed on the first seal, and passages are provided that communicate with the groove and the outside to channel the machining fluid drainage path. The first seal may be composed of a plurality of members. A suction device sucks up machining fluid draining from the passages.Type: GrantFiled: April 24, 2006Date of Patent: March 30, 2010Assignee: Fanuc LtdInventors: Yuki Kita, Shinji Okuda, Hikaru Yamane

Publication number: 20070228015Abstract: A lower arm is passed through a slot in a machining tank. The slot of the machining tank is provided with a seal section for sealing with a plate-shaped seal member. The movable table is moved by a servomotor. The machining tank and a workpiece are fixed on the movable table. At the seal section, a seal member on the machining tank side slides with respect to the plate-shaped seal member, thereby generating a sliding resistance. This sliding resistance increases as a sludge produced by electric discharge adheres to the seal section, thereby distorting the lower arm and influencing the machining accuracy. Accordingly, a load that acts on the servomotor is detected, and a sliding resistance load at the seal section is obtained. When a reference load is exceeded by the detected resistance load, arrival of the seal section at the timing for maintenance is displayed and notified.Type: ApplicationFiled: March 6, 2007Publication date: October 4, 2007Applicant: FANUC LTDInventors: Yuki Kita, Shinji Okuda, Hikaru Yamane
