Description
Technical Field
The present invention relates to a machining method and a machining machine, and more particularly to a hard turning method for cutting a groove in an inner bore of a high lead ball nut and a lathe apparatus using the same.
Background
In order to improve the industrial processing efficiency, the movable table of many CNC machines is driven by a linear motor capable of moving at high speed. However, in addition to the high price, the linear motor is not an optimal solution for high-speed movement because the precision control needs to be implemented by a digital encoder sensor (optical ruler, magnetic ruler) capable of precise positioning. The driving of the moving table of the conventional CNC machine tool is mostly controlled by the ball nut and the screw rod for driving and precise positioning. However, when the lead of the ball nut and the screw is less than 2 times or even 3 times, the effect of high-speed movement is not easily achieved. Therefore, 2 and 3 times higher lead ball nuts and screws are the key to the development of CNC machine tools with high speed movement.
In order to make the operation of the ball nut on the screw more precise and smooth, the threaded ball groove in the ball nut, which is in contact with the ball, adopts the heat treatment hardening and grinding processes to improve the dimensional accuracy and the geometric accuracy of the threaded ball groove, as shown in the schematic diagram of the grinding process shown in fig. 1, and the grinding wheel 100 can further penetrate into the ball nut 200 during the grinding process of the low-lead ball nut 200. However, when the specification of the ball nut is increased to 2 times and 3 times of the high lead specification, the grinding process of the thread ball groove cannot be achieved by the conventional grinding equipment, and as the grinding wheel 100 shown in fig. 2, the wheel shaft interferes with one end of the ball nut 200, so that the lead angle of the thread ball groove cannot be used to deeply penetrate into the inner hole 201 of the ball nut 200 for grinding.
In addition, a manufacturer may use a hard cutting processing method instead of the grinding process, so that a ball nut workpiece is subjected to rough processing and heat treatment hardening, and then a CBN (boron nitride) lathe tool is directly used for precisely turning a thread ball groove, as shown in fig. 3 and 4, one end of a ball nut 10' is clamped in a chuck 20 of a threading machine, a tool holder 40 is fixed on the tool holder 30, and a CBN (boron nitride) blade 50 is provided at the front end of the tool holder 40; thereby, the tool holder 30 is controlled to move, and the CBN (boron nitride) insert 50 at the front end of the tool holder 40 is inserted into the inner hole 101 'of the ball nut 10' to perform cutting of the thread ball groove.
However, in the conventional threading machine or CNC threading machine, only the rear end of the tool holder 40 is fixed to the tool rest, and the front end of the tool holder 40 (including the insert 50) is suspended, and if a long ball nut is to be machined, the length of the tool holder 40 is longer, so that the fixing point of the tool holder 40 to the insert 50 is too long, and the tool holder 40 is liable to vibrate during the cutting process, which causes problems of poor cutting surface precision, shortened tool life, increased dimensional error, and the like.
In addition, the machining operations such as threading and drilling are performed in a CNC manner, so that it takes a long time to calibrate the nut material after the nut material is mounted on the machining machine, otherwise there is a problem of accuracy, and the difficulty and the completion time of the operations are increased. Therefore, the traditional nut material processing mode has the problems of high production machine cost, long integral processing operation time, poor accuracy, or much calibration time consumption and the like. The disadvantages of the known techniques described above should be excluded.
