摘要： PURPOSE:To reduce an idling time, by shortening an actual cutting period of a lathe processing a lathed part whose length is longer in comparison with especially a diameter. CONSTITUTION:An object to be processed, which is inserted into a hollow of a main shaft 20, is supported by a collect chuck 23. The projection of the end is inserted into a guide bush 23, and is supported there. A desired processing part of the object to be processed is positioned in a inlet part of the guide bush 23 as a result of adjusting the position of a headstock 12. The main shaft 20 is rotated at a given speed by rotating a motor 30, and thus, the object to be processed is rotated. Either or both of the headstock 12 and a saddle 44 are moved according to a numerical control, and a processing is performed after selecting desired tool as a result of indexing-positioning a turret head 48.

摘要： PURPOSE:To make programming work so easy, by controlling a first tool with the program stored in a first memory means, and a second tool with the operational result added of finishing allowance by an arithmetic unit, respectively at the same time. CONSTITUTION:When a workpiece 1 is machined simultaneously by a finishing cutting tool 21 and a roughing cutting tool 23, a finishing program is inputted into a numerical control system, and a finishing size (diameter) x is added to a first memory device 41, furthermore the finishing size (x) stored in an arithmetic unit 42 and the inputted finishing allowance (a) are added together, finding a roughing size (y), and it is stored in a second memory device 43. With this constitution, the finishing cutting tool 21 is moved in an X direction and positioned so as to become the specified finishing diameter (x) as well as the roughing cutting tool 23 is moved in a Y direction and positioned so as to become the specified diameter y=x+a, respectively, whereby roughing and finishing of the workpiece 1 are carried out at the same time. Thus, programming becomes easy, while possibility of occurrence of the composition miss is also reducible.

摘要： PURPOSE:To make a tool for the following process stand by near a workpiece while machining or to carry out simultaneous machining by providing headstocks and a guide bush, a first tool rest which slides perpendicularly to them, a second tool rest which slides both in parallel and perpendicularly to them, and an operation correcting means. CONSTITUTION:A workpiece is mounted on the main spindle of a headstock 22, and machined with a tool 33 installed on a turret 34 of a first tool rest 32 through a guide bush 11. Also, during this machining, the tool 45 of the turret 46 of a second tool rest 44 can be moved in the direction of Z2, or X2, so as to be kept standing by near the workpiece, or to carry out simultaneous machining. The simultaneous machining is carried out which a corrected moving quantity, by adding the feeding quantity and speed of a Z1 axis to those of a single Z2 axis. It is also possible to carry out simultaneous machining by making an opposite main spindle 52 hold a separate workpiece and using a tool 45. Thus, by controlling headstocks which are opposite to each other with a guide bush interposed in between, and first and second tool rests, by means of an NC device, it is possible to make a tool for the following process wait near a workpiece while being machined by another tool, or to carry out simultaneous machining.

摘要： PURPOSE:To enhance the effectiveness in works by providing No.2 tool rest with capability of independent movement both in the direction along spindle and the one across the same, allowing No.1 and No.2 tool rests to work at the same time, and by controlling both tool rests by a simple control program. CONSTITUTION:In this automatic lathe with fixed spindle stock, control is made with the same program as designed for a conventional NC auto-lathe while No.2 tool rest 31 lies at the point of origin for movement. When simultaneous processing is made with tools 14, 15 on these two tool rests 28, 31 in order to shorten the time of works, such operations as advancing No.2 tool rest 31 till the processing position in the direction across the spindle axis and offsetting the cutting points with the tools 14, 15 slightly from each other shall be added to the motion of No.1 tool rest 28. This allow managing the sliding amount of guide rail 29 and stroke of the fitting shaft 33 with a minor scale as well as making the system with small and simple construction. Further, the program for control can be provided only through addition of a program for movement of the tool rest 31, which does not require any complicated procedure for preparation.

摘要： PURPOSE:To improve workability by a device and reduce its noise, by arranging a plurality of feed tubes to be lined in a circular shape while recirculating lubricating oil in a hollow part for a bar material fed by a push rod. CONSTITUTION:A supply device, arranging eight feed tubes 5 to be lined in a circular shape at a predetermined space and controlled by a rotary angle detector 14, stops the feed tube pitch by pitch. The device, inserting a push rod 15 into a hollow part 9 in the tube 5, supplies a bar material 4 to a main spindle of a lathe. The device improves workability because the bar material 4 is supplied by successively rotating the plural feed tubes 5. The device, supplying lubricating oil to the hollow part 9 of the tube 5 via a supply oil pipe 23 to be recirculated via a pipe 27, reduces a noise due to a contact between the bar material and the tube.

摘要： PURPOSE:To shorten a distance of movement of each part and simplify structure and further improve efficiency of work by longitudinally moving a back surface machining main shaft and putting it in synchronous rotation with the main shaft of a lathe. CONSTITUTION:Turning cut of a rod material 6 is performed through feeding a tool post 3 forward, and bringing the first or the second tool rests 4, 5 close to the rod material 6 and then cutting it by means of a tool 43 and the like fitted on said tool rests. When the cutting process is finished, a workpiece is cut off through direct cutting. Upon completion of the direct cutting work, a cross slide 3 retreats, while the rod material 6 in the main shaft 7 of the lathe is pushed out by a predetermined amount. Thus, the next process is started by means of the tool 43 and the like of the first turret tool rest.

摘要： PURPOSE:To shorten the time required for tool selection, by making the selection of a lot of tools and their drive and control attainable with two numerically controlled spindles, namely, servomotors alone. CONSTITUTION:A cutting tool 25a at the left of a tool post 22 is being selected and, after machining is over, supporsing that a cutting tool 26b is selected, a servomotor 18 rotates whereby the cutting tool 25a retracts to the extent of each cutting edge reference position of the paired cutting tools 25. Next, the selected cutting tool 26b is made into rapid feed up to the cutting edge reference position of the paired cutting tools 26. In succession, the cutting tool 26b advances (to the left) up to the specified depth whereby the next metalcutting starts with a headstock 2 advanced.
