A hardware accessory manufacturer explains how to improve the machining accuracy of automatic lathes.
CNC lathe machining is currently one of the most widely used machining methods. Compared with conventional lathes, CNC lathes offer higher machining accuracy and better dimensional consistency of the machined parts. They also enable a single operator to handle multiple machines simultaneously, thereby boosting labor productivity, reducing defect rates, and lowering labor costs. In the automotive manufacturing industry, gear hobbing for transmission shaft splines, as well as the machining of axle gears and transmission gears, occupy a remarkably important position. Traditional spline and gear milling machines suffer from relatively slow cutting speeds and lower precision during the machining process. To improve machining efficiency, many companies have adopted high-efficiency CNC spline milling machines—also known as automatic lathes.

The machining accuracy is high, and the dimensional consistency of the machined parts is excellent. It enables one operator to handle multiple machines simultaneously, thereby improving labor efficiency, reducing the defect rate, and lowering labor costs.
In the automotive manufacturing industry, gear-shaft spline shaft rolling and the machining of axle gears and transmission gears occupy a remarkably important position. Traditional spline and gear milling machines suffer from relatively slow cutting speeds and low precision during the machining of splines and gears. To improve processing efficiency, many companies have adopted CNC high-efficiency spline milling machines— Automatic lathe Let’s now turn to the machining of spline shaft components. This type of machine tool can process various standard types of splines, gears, stepped gears and splines, as well as tapered gears and splines. For example, a certain enterprise has adopted a YKX6012 CNC high-efficiency spline milling machine. The effective length of the spline being machined is 77 mm, and the spline hobbing cutter rotates at 300 r/min. The time required to machine one part is calculated as follows: t_machine = (L + l) × Z / (S0 × n) = (77 + 5) × 22 / (1.8 × 300) = 4.07 minutes; t_total = t_machine + t_setup = 4.07 + 1 = 5.07 minutes. In contrast, the production time for a single part on a conventional spline milling machine is 22.78 minutes. Thus, 22.78 / 5.07 ≈ 4.4 times—this clearly shows that the CNC high-efficiency spline shaft milling machine can increase production efficiency by more than four times compared to a conventional spline shaft milling machine.
