Full Thread Screw

• 1.1 Carbon steel full-thread lead screw: It has high strength and hardness, can withstand large loads, has a relatively low price, and is widely used. Generally, it is subjected to surface treatments such as galvanizing and blackening to improve its corrosion resistance.
• 1.2 Stainless steel full-thread lead screw: It has good corrosion resistance and oxidation resistance, and is suitable for corrosive environments such as moisture, acid and alkali. Common materials include 304 stainless steel and 316 stainless steel.
• 1.3 Alloy steel full-thread lead screw: It has excellent comprehensive performance, high strength, hardness and wear resistance, and is often used in occasions with high requirements for lead screw performance, such as aerospace, precision machinery, etc.
• 1.4 Titanium alloy full-thread lead screw: It has the advantages of low density, high strength, and good corrosion resistance, but the price is relatively high. It is generally used in high-end fields such as aerospace, medical equipment, etc.

2.1 Triangular thread full-thread screw: The thread profile is triangular, with good self-locking and low transmission efficiency. It is often used in occasions that require precise positioning and fixing, such as machine tool workbench movement, fixture clamping device, etc.

2.2 Trapezoidal thread full-thread screw: The thread profile is trapezoidal, with high transmission efficiency, large load-bearing capacity, and relatively simple processing technology. It is the most common type of full-thread screw and is widely used in various mechanical transmissions, such as jacks, presses, and lathe feed mechanisms.

2.3 Rectangular thread full-thread screw: The thread profile is rectangular, with high transmission efficiency, but it is difficult to process and has low centering accuracy. It is often used in some occasions with high transmission efficiency requirements and large loads, such as large cranes and winches.

2.4 Sawtooth thread full-thread screw: The thread profile is serrated, combining the advantages of trapezoidal thread and rectangular thread, with high transmission efficiency and large load-bearing capacity. It is suitable for transmission occasions with unidirectional force, such as screw presses and rolling mills.

1. Mechanical processing field:

1.1 Machine tool equipment: Full-thread lead screws are key components of machine tool feed systems, used to control the precise movement of workbenches, tools, etc., to ensure processing accuracy. For example, on lathes, milling machines, drilling machines, grinders and other machine tools, the precise positioning and feeding movement of workpieces are achieved through the transmission of full-thread lead screws.

1.2 Automated production line: In automated production lines, full-thread lead screws are used to control the movement of various actuators, such as material conveying devices, robot arms, etc., to achieve precise position control and action execution in automated production processes.

2. Construction and decoration field:

2.1 Scaffolding construction: Full-thread lead screws can be used to adjust the height of scaffolding, so that it can adapt to different building heights and construction requirements, and ensure the stability and safety of scaffolding.

2.2 Ceiling: In ceiling construction, full-thread lead screws are used as hangers to fix ceiling keels, adjust the height and flatness of ceilings, and make ceiling installation more firm and beautiful.

3. Automobile manufacturing field:

3.1 Automobile parts processing: In the process of automobile parts processing, full-thread lead screws are used to control the movement of processing equipment to ensure the processing accuracy of parts, such as engine cylinder block, cylinder head, crankshaft and other key parts processing.

3.2 Automobile assembly line: In the automobile assembly line, full-thread lead screws are used to control the movement of assembly equipment to achieve precise assembly of parts, such as door installation, seat adjustment, etc.
