Processing Techniques

The previous screw thread processing was done through turning, with the process route being: cold drawing + knurling + turning threads + alignment → drilling + cutting + chamfering. This method was not only inefficient and costly but also prone to deformation during turning and knurling due to the low stiffness of small round steel. Regarding the T28*5 trapezoidal screw, it is difficult to produce small-sized sprockets. To address this, we have designed a whirlwind milling screw thread machine. It not only increases the rotational speed from the previously experienced 1000 r/min to over 2000 r/min but also completes the milling and knurling in one operation. The new process route is: cold drawing + knurling, milling threads + alignment + drilling, cutting → chamfering. Although whirlwind milling may cause significant deformation in small-diameter workpieces (larger components have less deformation), alignment is still manageable. The improved process has the following characteristics:

Surface roughness values reduced.

Vibration reduction caused by cutting force

The cumulative pitch error of the small path workpiece has a certain increase.

Trapezoidal screw with double nut and spring design

We need to select the appropriate nuts. In double nut spring pre-tension designs, the quality and precision of the nuts are crucial for the pre-tension effect. Generally, nuts should be chosen that are of high quality and well-made.

Manufacture products with high precision and ensure that the distance between the two nuts is as equal as possible to avoid uneven loading and unstable movement.

We need to determine the appropriate spring. The selection of the spring should be based on the actual application. Generally speaking, the stiffer the spring, the greater the preload, but it will also increase friction and resistance.

Therefore, when selecting springs for T4*1 trapezoidal screw manufacturers, it is necessary to consider factors such as transmission accuracy, movement speed, and load.

Cautionary Notes

The material must be round steel from a recognized brand; otherwise, the workpiece surface is prone to form scales and burrs, and the邢台 trapezoidal screw, milling cutter, and rolled thread cutter will experience rapid wear and breakage.

During processing and assembly, the roll threading tool must move more freely within the groove without excessive gaps. If the gaps are too large, the roll cutter wheel will tilt during operation, resulting in uneven patterns and increased risk of damage to the tool itself.

The plate should cover the thread roller completely to prevent chips and debris from splashing in, ensuring the quality of T8 trapezoidal screw threads.

Do not lubricate or cool the roll-threading cutter while in use to prevent damage to the adjacent carbide cutting blades.

First, start the lathe to rotate the workpiece, then tighten the screw to prevent excessive static friction and the workpiece from slipping.

Choose high-quality rolling dies to reduce the number of tool changes: Regularly remove the quick-change cover to clean the die slots
