摘要： PURPOSE:To quickly regulate a gap into proper size at all times by stopping drive by a servo actuator, when the torque of the servo actuator reaches its prescribed value. CONSTITUTION:Rotation speed of a main spindle 2 is gradually increased so that a regulation nut 15 is rotated in such a direction of decreasing a void between a bar material 1 and a guide bush 12. Torque of a servo motor 30A for the main spindle, when the main spindle 2 rotates the regulation nut 15 via a regulation pin 20, is measured by a torque measurement means 31A so as to be input in a judgement means 35A. And the torque measured by the torque measurement means 31A is inputted in a torque set means 33 beforehand so that whether it reaches a prescribed torque stored in the judgement means 35A is judged. When the judgement means 35A is judged that the drive torque of the servo motor 30A for the main spindle reaches its prescribed value, rotation of the servo motor 30A for the main spindle is stopped based on the judgement result. Torque regulation completion is indicated on a display means 37.

摘要： PROBLEM TO BE SOLVED: To prevent a bar material from swinging by deflecting by using a sevomotor as a motor for a material feeder and a motor to move a main spindle, and outputting a command to impart constant torque to the motor for a material feeder so as to absorb play of a transmitting means when the respective motors are synchronously driven. SOLUTION: A main spindle 3 of an NC automatic lathe 1 is moved in the main spindle axis direction by a motor 5 to move a main spindle, and a bar material 2 is supplied by inserting the main spindle 3. A bar material supply device 8 is constituted so that a feeding bar 21 having a finger chuck 20 to grip the rear end of the bar material 2 is moved by a chain conveyor 22 driven by a motor 26 for a material feeder. In this case, the motor 26 for a material feeder and the motor 5 to move a main spindle respectively use a sevomotor, and are controlled so that a moving command to synchronously drive them is outputted to the respective motors 5 and 26 from a control device and a constant torque command is imparted to the motor 26 for a material feeder so as to absorb play such as looseness of the cain conveyor 22.

摘要： PURPOSE:To miniaturize a numerically controlled lathe by forming a guide push supporting table as a comb-teeth tool rest supporting table. CONSTITUTION:The first tool 36 on a comb-teeth tool rest 32 is used in machining the contour of a rod-shaped work held on a spindle 12 and moved in the X1 axis direction by moving the spindle stock 13 in the Z1 axis direction through the use of biaxial simultaneous control, and thereby a specified cut-in depth is generated. Thereby the contour of a work held on the spindle 12 is machined into any desired shape such as a straight line, taper, an arc of a circle, etc. To machine with the first tools 36f, 36g, 36h, the spindle 12 is stopped rotating, and the side faces of the work are subjected to all intended processings from the contour such as boring, etc. To subject the work to the processing in the axial direction such as processing of the bore, the second tool 43 on a turret tool rest 40.

摘要： PURPOSE:To have inexpensive apparatus by installing a guide bush connection means on a spindle and holding a workpiece in a guide bush with advance of a head stock. CONSTITUTION:When it becomes impossible for a collet chuck within a spindle 5 to hold a workpiece 10 due to next product machining, a stopper member is positioned at a predetermined point in front of a rotary guide bush device, so that the collet chuck of the main spindle opens and the workpiece 10 is pushed out until it gets in contact with the stopper member, and then a head stock 3 advances. Accordingly, a lever 22 for opening/closing a guide bush 19 rocks by means of an extension portion of a cap nut 9 of the spindle 5, so that the workpiece 10 is held by the guide bush 19 and a clutch portion 9b of the cap nut 9 and a clutch portion 18c of a guide bush sleeve 18 are fitted together. Consequently, machining is made by holding the workpiece 10 in a guide bush 19.

摘要： PURPOSE:To enable a decrease in a delivery quantity to be surely detected further prevent a cutting chip from causing a trouble as staying or the like, by allowing a part of cutting oil, supplied to a delivery port, to flow into an auxiliary tank communicating with an outlet part and detecting the position of a liquid level. CONSTITUTION:A device causes no switch to operate in the position where cutting oil allowed to flow into a cutting oil tank 10 obtains a normal liquid level SL. Next the cutting oil, if its pressure in a pipe increases due to blocking or the like of a cutting chip in a delivery port to lift the liquid level, causes a float 13 to rise, and if the liquid level reaches the upper liquid level at abnormal time, a switch 16 closes, while the detecting device, decreasing a pressure of the cutting oil in the pipe to lower the liquid level due to failure of a cutting oil pump or blocking of the chip in the pipe and closing a switch 18 if the liquid level reaches the abnormal bottom liquid level LL, alarms a decrease in quantity delivered of the cutting oil by generating each signal. In this way, the generation of a trouble due to insufficient supply of the cutting oil and the generation of a flame due to overheat of the cutting chip can be prevented before occurrence.
摘要翻译：目的：为了能够进一步防止输送量的下降，进一步防止切屑由于滞留等而引起的故障，通过供给到输送口的切削油的一部分流入辅助槽内进行通气具有出口部分并检测液位的位置。构成：设备不会在切割油流入切割油箱10中获得正常的液面SL的位置上操作。接下来，切削油，如果其管道中的压力由于输送口中切割芯片的阻塞等而增加，以提升液面，则浮子13升高，并且如果液位达到上液位异常时间，开关16关闭，而检测装置降低管道中的切削油的压力，以降低由于切割油泵的故障引起的液位或堵塞管道中的芯片，并闭合开关18，如果液位达到异常底液液面LL，通过产生每个信号来报告切割油输送量的减少。以这种方式，可以防止由于切削油的供应不足而导致的故障的产生以及切屑的过热导致的火焰的产生。

摘要： PROBLEM TO BE SOLVED: To attain an electrically driven engagement and disengagement mechanism for fixing a turret firmly at an indexing position on a supporting base and releasing the fixing without need for an additional motor. SOLUTION: This turret tool rest device is provided with a movable engagement member 40 capable of being engaged with both of supporting base 20 and a turret 24. The movable engagement member 40 is provided with an annular cam part 46 connected to the back, end of a main body part 42 through a plurality of legs 44 and an annular coupling part 48 attached to the front end of the main body 42 with bolts 47. The annular cam part 46 is provided with a driven ring element 74 slidably-accommodated in an annular groove path 70 at a groove cam ring element 72. When the supporting base 20 makes X-axis movement on a tool slide, the driven ring element 74 rotates within the annular groove path 70 at the groove cam element 72 to move the groove cam ring element 72 in the axial direction. It is thus possible to engage and disengage teeth 54 formed at the annular coupling part 48 with the fixed teeth 58 of the supporting base 20 and the rotating teeth 62 of the turret 24.
