Problems solved by technology
[0002] With the continuous development of numerical control technology, computer technology, machine tool technology and processing technology, traditional processing concepts can no longer meet people's requirements for processing speed, efficiency and precision.
[0003] The current screw parts are characterized by multiple varieties and small batches, complicated process, and the widespread use of integral rods is difficult to process. Therefore, long processing time, large material removal, high cost, low processing efficiency, and stress deformation are common in the manufacturing process. Severe bottlenecks. In the process of producing space screw tooth profile, most factories choose screw grinder as finishing equipment, but the high price of grinder increases the manufacturing cost, and the production efficiency of grinder is low when producing screw, and the cost of consumables high

Embodiment Construction
[0028] The present invention will be further described in conjunction with the accompanying drawings.
[0029] see figure 1 , figure 2 and image 3 , the present invention designs a high-efficiency finish milling process for space screw tooth profile, which is characterized in that: the carbon steel bar is rough milled or cast to form the space screw workpiece of the tooth profile, and then the finished product is finished after fine milling, such as the material adopts nodular The cast iron can be split-mode precision casting, leaving a finishing allowance of 2mm, so that the refined space screw with the precision fully meeting the requirements can be produced through the final finishing milling, which is more cost-effective and more efficient; the machining speed of the tool is 80m / min , the speed is 100rpm, the number of tool teeth is 7, the feed rate per tooth of the tool is 0.05mm / z, and the feed rate is 35mm / min; the spindle head speed of the tool is 50-280min -1 , the...
