Non standard customization of lead/Slide screw with ball thread and brass nut for 3d printer parts

Introduction to the basic knowledge of Lead screw

There is a component on the machine that is made of long, thin metal bars. The top is a very smooth surface, some with thread. Generally there are threads on the machine tool, called lead screw.

1, According to the national standard GB/T17587.3-1998 and its application example, ball screw (which has replaced trapezoid screw at present) is used to transform rotating motion into linear motion; Or the linear motion can be transformed into an executive element of rotating motion, and it has the characteristics of high transmission efficiency, accurate positioning and so on.

2, when the screw is used as the active body, the nut will be transformed into a straight line motion according to the corresponding guide path with the rotation angle of the screw, and the passive workpiece can be connected by the screw base and the nut, thus the corresponding linear motion can be realized.

3, because there is no clearance between ball screw wires, the accuracy of straight line movement is high, especially in frequent commutation, there is no need for gap compensation. Ball screw wire friction between the mother is very small, rotation is very easy.

4, When connecting ball screw with motor, coupling must be installed in the middle to achieve flexible connection. The synchronous belt can be directly connected with the motor output shaft with the synchronous wheel.

5, According to the national standard GB/T17587.3-1998, ball screw pairs are divided into two categories: positioning ball screw pair (P) and transmission ball screw pair (T). The accuracy level is divided into seven grades, that is, 1, 2, 3, 4, 5, 7, 10, and grade 1 has the highest accuracy. Decrease in turn. Select high-quality screw to identify titanium Hao machinery, professional quality assurance, because professional, so excellent!

6, ball screw rotation a week nut movement distance for a pitch distance, If the screw is the distance from which the nut moves four (or five) helices each week, it means that the screw is a four (or five) screw, commonly known as four (or five) screws.

Generally, the small lead ball screw adopts a single wire, and the medium, large or large lead adopts two or more wires. Efficient machining method of screw rod——High-efficiency processing of cyclone milling screw screw Cyclone milling is a high-speed milling threading device installed on the lathe and lathe. The cyclone milling is installed on the lathe. The lathe clamps the screw to complete the low speed. In the feed motion, the cyclone milling drives the outer rotary cutter carbide cutter to rotate at high speed to complete the cutting motion. A threading method for milling threads from a lead screw. Because of its high milling speed (speed up to 400m / min), the processing efficiency is fast, and the compressed air is used for chip cooling. The chip is splashed like a cyclone during the machining process - the screw is whirlwind.
