Abstract
A dedicated NC (Numerical Control) machine tool for milling a keyway adopts computer programs to control the machine tool to mill shaft keyways so as to satisfy the requirements of dimensional precision in drawing design. A NC operation box and a NC guide rail control box are used for controlling the processing technology of each milled keyway, and a display screen automatically displays processing data so as to satisfy the machining accuracy requirements. A NC feed box adopts a frequency conversion stepless speed change mechanism. The milling to the shaft keyways is controlled by a computer completely, and the feeding, the withdrawing, the positioning and the depth of the milling can be controlled automatically. The NC guide rail control box adopts a high-precision ball screw, angular contact ball bearings are installed at the two ends of the ball screw, and the ball screw is controlled through a servo motor, so as to lead the NC guide rail control box to move forwards and backwards on a guide rail of the machine tool and ensure the length dimension precision of the shaft keyways. The guide rail of the machine tool and the ball screw adopt a centralized lubricating oil supplying device, so as to ensure that the friction coefficient of the guide rail of the machine tool and the ball screw is low and the service life is long. The dedicated NC machine tool is convenient and safe to operate, achieves energy conservation, and improves the product quality and production efficiency.
