A ball screw is a mechanical component used to convert rotational motion into linear motion with high precision and efficiency. It consists of a screw shaft with a spiral groove and a ball nut that contains recirculating ball bearings placed within the groove. The purpose of a ball screw is to provide a smooth and efficient means of translating rotational motion to linear motion or vice versa. Ball screws offer several advantages over other types of screws, such as machine screws: 1. High Efficiency: Ball screws have a rolling contact between the screw shaft and ball nut, which results in reduced friction compared to sliding contact found in machine screws. This rolling contact allows for greater efficiency in converting rotational force to linear motion and vice versa. 2. High Precision: The ball bearings in a ball screw assembly provide precise and smooth motion with minimal backlash. This makes ball screws suitable for applications that require accurate positioning, such as CNC machines, industrial robots, or precision machining tools. 3. Reduced Friction: The rolling contact between the ball bearings and screw shaft reduces friction, resulting in lower power consumption and heat generation. This characteristic makes ball screws more efficient and suitable for applications where high-speed or continuous operation is required. 4. Long Service Life: Ball screws are designed to withstand high loads and provide long service life. The use of ball bearings reduces wear and tear, resulting in extended operational durability and reduced maintenance requirements. While ball screws offer numerous benefits, they are typically more expensive than machine screws due to the complexity of their design, the precision manufacturing processes involved, and the cost of the ball bearings used in the assembly. The higher cost is often justified by the improved performance and longevity provided by ball screws in demanding applications.
Read MoreThere are generally two main types of ball screws: 1. Ground Ball Screws: These ball screws are produced through grinding processes that ensure high precision and accuracy. They offer low friction, high efficiency, and excellent positioning accuracy. Ground ball screws are commonly used in applications that require high performance and precision, such as CNC machines, robotics, and aerospace equipment. 2. Rolled Ball Screws: Rolled ball screws are manufactured by pressing or rolling the thread profile onto the screw shaft. They are generally less expensive than ground ball screws but offer slightly lower accuracy and efficiency. Rolled ball screws are often used in applications that require lower precision, such as in certain industrial machinery and automation systems. There may be variations and special designs within these two main types of ball screws, depending on specific application requirements.
Read MoreWhat are the precautions for using linear guides? 1. Prevent linear guide rails from rusting When holding the linear guide rail directly with your hands, wash off the sweat on your hands and apply good quality mineral oil before replacing them. Pay special attention to rust prevention during the rainy season and summer. 2. Keep the linear guide operating environment clean Keep the linear guide and its surrounding environment clean. Even if tiny dust invisible to the naked eye enters the guide, it will increase the wear, vibration and noise of the guide. 3. Install linear guide rails carefully. Linear guides must be carefully used and installed. Vigorous stamping is not allowed, the guide rail is not allowed to be directly struck with a hammer, and pressure is not allowed to be transmitted through rolling elements. 4. The linear guide rail installation tools must be suitable Use appropriate and accurate installation tools for linear guides. Use special tools as much as possible, and try to avoid using things like cloth and short fibers.
Read MoreThe difference between ground ball screws and rolled ball screws lies in the different processing methods. Ground ball screws are manufactured by mechanical processing, while rolled ball screws use a one-time forming method. Grinding ball screws are targeted at industries with higher precision requirements, and their use costs are higher. The precision of rolled ball screws is low, and the cost is low when used in industries that do not require high precision. Rolled ball screws are cold-rolled and have very low precision, usually C7 precision. Better manufacturers can barely achieve C5 precision, but one advantage is that the production cycle is short and the delivery time is fast. The production process of grinding-grade ball screws is relatively complicated. They are ground using ultra-precision grinding machines and require quenching in the middle. The accuracy can reach the highest grade C0, but the delivery time is very slow. Our company's grinding ball screw processing cycle is usually 30-35 days. In peak seasons when orders are large, it needs to be postponed for about 5-10 days. The rolling ball screw processing cycle is very short, and the construction period is usually about 5-7 days ( Orders must be placed in the order in which they are placed). Customers in need are welcome to discuss cooperation!
Read MoreTrapezoidal screw materials: 1.General precision (referring to grade 7~9) Trapezoidal screws, for light loads, are usually made of non-alloy medium carbon structural steel (such as 45, 50 steel), normalized, quenched and tempered, or cold-rolled free-cutting steel (such as Y45MnV) Directly machined. For those with wear resistance requirements, quenched and tempered non-alloy structural steel (such as 45, steel) can be used, and it can be used directly after ammonia carburizing treatment. Screws used for measurement and with little stress can be made of quenched and tempered non-alloy structural steel (such as 45, 40Cr steel), which can be used after induction heating and surface quenching. 2.Precision (referring to level 6 and above) Trapezoidal screws are usually made of non-alloy (carbon) or low-alloy tool steel (such as T10A, T12A or 9Mn2V, CrWMn steel) for light loads, and are quenched and tempered or spheroidized annealed. Screws that work frequently are often made of low-alloy tool steel (such as 9Mn2V, CrWMn steel) and integrally quenched. They can also be made of high-grade nitriding special steel (such as 38CrMoA1A, 35CrMo steel) and undergo infiltration treatment to withstand high temperatures. temperature situation. Small-sized screws that require wear resistance can be made of carburized low-alloy steel (such as steel), and can be used after carburizing + quenching and low-temperature tempering. For screws that work at high temperatures, they can be made of precipitation-hardened stainless steel (such as OCr17Ni4Cu4Nb) and used after solid solution + aging treatment.
Read MoreAs an important moving component, linear guides are an indispensable component for many machines. So many customers need to install them by themselves after purchasing linear guides. What should they pay attention to when there are no technical personnel present? Let’s talk briefly today. You can consult our technical staff for specific operations. The first thing to note is not to remove the slider from the guide rail at will. Normally, we ship the slider and the guide rail together, which means that the slider is of good quality, because there are balls inside the slider. If you take it out without paying attention, it may cause the balls to slip. If the ball is lost, the slider cannot be used. Generally, our manufacturer will be equipped with a slider push-off device to assist in removing the slider and reduce the occurrence of ball falling off. In addition, disassembling the slider during assembly may cause dust and dust in the environment to fall in. After reinstalling, the motion may be stuck and the accuracy may be reduced, which is not worth the gain. So before the formal installation, we must first carefully clean the installation location, remove burrs, dust and other dirt on the work surface, and keep the work surface smooth and tidy. In addition, it is necessary to apply anti-rust oil to the linear guide rail to prevent rust from affecting the normal function and performance of the product in future use. Linear guide rails are usually fixed with bolts. Each model has a recommended bolt model. Customers are also asked to use the recommended sizes. When fixing the bolts, be sure to tighten them and keep the track and the workbench close to each other without shaking. After tightening them all, drive the hole cover into the assembly bolt to keep it on the same level as the top surface of the linear guide rail. There are some technical requirements for the assembly and installation of linear guides. We recommend that our customers find relevant technicians or consult the manufacturer for technical support during organization and installation.
Read MoreKK modules, like linear guides, play a significant role in the mechanical industry. Linear guide rail is a common and commonly used transmission accessory, while KK module is relatively less common. Today, let's talk about how to verify whether KK module can be used. This institution uses many modules, and the servo motor is used to drive the modules. The quick acting shaft in the motor is connected to the ball screw in the module through a coupling, and the motor works to drive the screw to rotate, thereby driving the entire machine to move. Regardless of the direction, servo motors are used in combination with modules to drive the vacuum disc to move materials up, down, up, and down. The central adsorption of materials also requires the use of cameras and light sources to detect the angle of material placement, and the ranking angle is adjusted through another servo motor. The selection of KK modules requires consideration of positioning accuracy and stroke, as different models of modules have different strokes.

Read MoreOur company has extremely rich experience in custom manufacturing CNC machining, milling and turning aluminum parts. We can manufacture castings of different types and materials. Today we focus on impeller castings. Let me give you an in-depth understanding of this casting product.The picture below is a physical picture of the impeller. Impellers are critical components in various industries including power generation, aerospace and fluid mechanics. In the world of power generation, these superb blades sit at the heart of turbines and determine large-scale electricity production. Its function is to pressurize or convert energy to the flowing liquid or gas. Commonly used materials for impellers include cast iron, cast steel, cast aluminum and non-metallic materials. According to their structures, they can be divided into closed impellers, semi-open impellers and open impellers. Among them, the closed impeller is composed of blades and front and rear cover plates. Since there is no underflow loss in the closed impeller, the efficiency is high. Closed blades usually have irregular curved surfaces with large warpage, thin wall thickness, and high quality requirements such as dimensional accuracy, shape tolerance, and surface roughness. We will take the feasibility and reliability of casting production into consideration when manufacturing, because these ultimately determine the quality of castings. Therefore, we will summarize and establish an internal mold design experience database to minimize the occurrence of multiple changes in the later period due to insufficient consideration of the casting process during the design process.
