摘要： In a gear train in which a gear case encases a first gear meshing with a second gear having a diameter smaller than that of the first gear, a sufficient amount of lubricant is normally supplied to the upper second gear. As a result, it is possible to provide a lubrication structure of a gear train encased in a gear case designed to prevent occurrence of problems such as poor lubrication and seizure of a gear train. In a lubrication structure inside a gear case having a configuration in which the gear case encases the first gear meshing with the second gear having the diameter smaller than that of the first gear, and the first gear is disposed so as to have a minute gap between the gear case and an outer diameter of the first gear, oil inside an oil chamber below the first gear is pumped up with a movement of gear teeth forming a minute gap by a rotation of the first gear; the pumped oil is discharged into a space above the first gear and inside the gear case; the pumped oil is received by an oil receiver provided in the upper portion of the second gear and including a rib for receiving the pumped oil and a recess surrounded by the rib; and then the oil is supplied to lubricate a gear tooth portion and a bearing portion of the second gear.

摘要： A telescopic cover which relieves impact caused when a cover member is stopped moving and which is less meandering. A braking mechanism is provided between one of two adjacent cover members of the telescopic cover and the other of the two adjacent cover members which telescopically moves into and out of the one cover member. The braking mechanism is provided at a distal end portion of the one cover member, and has an elastic member that presses a slide member against the other cover member. When the other cover member moves relatively to the one cover member, a friction force generated by a pressing force of the slide member serves to brake the movement of the other cover member, whereby impact caused when the other cover member stops moving is relieved. The cover member in motion is always pressed by the slide member with an orientation thereof maintained.

摘要： A tool changing device and a tool cleaning method capable of surely removing foreign matter such as swarf adhered to tapered portions and/or flange portions of tools, which serve as contact faces to be in contact with a spindle. There is arranged tool cleaning nozzles for spouting coolant on both sides of the spindle in the rotating position of a turret. The tool cleaning nozzle has a position and a posture such that the coolant spouted from the nozzle hits against the tapered portions and/or the flange portions of the tools held by the turret. The coolant is spouted from the tool cleaning nozzle with the rotation of the turret at the time of tool selection. Each time the turret rotates, the tapered portions and/or the flange portions of the tools held by the turret are cleaned by the coolant. Even if foreign matter, such as swarf, is adhered to the standby tools held by the turret, it is possible to surely remove the foreign matter, such as swarf, since the tools are cleaned during the rotation of the turret.

摘要： A feed-shaft moving method and an apparatus capable of reducing non-cutting motion time. In a first section and a second section, an immediately preceding path is connected with a rapid traverse by a rapid traverse motion path having a curve continuous with the immediately preceding path. The movement is accelerated up to a rapid traverse speed while passing the curve. In the first section, the path is connected with the next path by a rapid traverse path having a curve continuous with the next movement. The movement is decelerated to the next moving speed while passing the curve. The rapid traverse motion of the feed shaft can be completed in less time, with unnecessary interruption and with no impact on the machine.

摘要： A numerical control device used in conjunction with a machine tool including a spindle head having a plurality of tapping tools is provided with a tapping pitch data group memory which stores the tapping pitch of each tool. Upon selection of a tool according to a machining program, a corresponding data group is retrieved from memory and from this data group an average tapping pitch is obtained. According to the average value thus obtained, a suitable feed rate is selected.
