Grinding principle of centerless grinding machine: centerless grinding method consists of three mechanisms: grinding wheel, adjusting wheel and workpiece support. The grinding wheel is actually used for grinding. The adjusting wheel controls the rotation of the workpiece and causes the workpiece to enter the cutting speed As for the workpiece support, which supports the workpiece during grinding, there are several ways to match these three parts, except for stopping grinding, which is the same in principle. The MG1020 centerless grinder is a very profitable machine because of its high accuracy, high efficiency, and high machine tool stability. However, few people

Solutions to Common Problems in the Use of Dies for Punching Equipment,The following 3 points have made solutions to the common problems used in punching die! The problem of punching the mold with the material, the mold with the material will cause the waste to rebound, and its related factors: The method to prevent the mold from feeding: The neutrality of punching diePunching dies are prone to wear in different positions on the sides of the punching core during use, and some parts have large scratches and fast wear. This situation is particularly obvious on narrow rectangular dies. The main

Using high-speed machining technology to process molds, in addition to the high quality of the processed products, can also significantly reduce or even eliminate inefficient grinding and manual post-machining man-hours, and shorten the overall mold manufacturing cycle. In order to adapt to market demands, the schedule for the development of new products is becoming shorter and shorter, and only the rapid introduction of products to the market can seize the opportunities (business opportunities). For example, the delivery period of mobile phone molds has traditionally been compressed from 45 days to 30 days, or even 14 days, from the entire process

Creep feed grinding is a grinding process, but more importantly, it is not like other forms of grinding. Mr. Nelson Beaulieu, Manager of Grinding Products Department of PTJ Shop, said that in a sense, creep grinding has more technical characteristics of milling. In the final analysis, peristaltic feed grinding is machined by means of deep cutting and large metal cutting, which is characterized by replacing the rapid reciprocating motion with a lower feed rate. Creep grinding tools, like grinding wheels, are deeply embedded in the machined materials. In fact, when the diameter of this tool is reduced and close to

Some parts and components of the machine tool that are relatively sliding, such as skateboards and guide rails, shafts and sliding bearings, worms and worm gears, etc., often have scratches or grooves on their surface after a period of operation. We call this phenomenon a research injury . Grinding damages the precision of the machine tool and affects the service life of the machine tool. If the repair is not timely, the particles generated by the grinding will also increase the grinding damage. When it is serious, it can make the sliding parts of each other stop sliding, resulting in

Gears and gear pairs specify 12 accuracy levels, with the first level having the highest accuracy and the 12th level having the lowest accuracy. The accuracy grades of the two gears in the gear pair are generally the same, but they can also be different. Gear tolerances and limit deviations are divided into three groups Gear tolerances and limit deviations are grouped Gears and gear pairs specify 12 accuracy levels, with the first level having the highest accuracy and the 12th level having the lowest accuracy. The accuracy grades of the two gears in the gear pair are generally the

The hardness of the ceramic tool is RA 93 ～ 94, the transverse breaking strength is (10 ～ 11) × 104psi, which is about half of the carbide, and the hardness at high temperature is very high. The hardness is still not reduced at about 2000ºF, so the cutting speed is 2 ～ higher than the carbide. 3 times. Due to particle size, purity, manufacturing methods and other factors, ceramic inserts are only suitable for cutting cast iron. When ceramic tools cut cast iron, a layer of low-shear-strength graphite is formed on the chip surface, which does not cause dents

PTJ can provide different clutch styles for spindle transmissions and other advanced transmission systems in the machine tool manufacturing industry, and can achieve very high accuracy in machining and calibration. For example, claw clutches, steel multi-disk clutches, metal bellows clutches, etc. For many years, the claw clutch RotexGS has been widely used in various machine tools. It can correct shaft misalignment, and more importantly, its function of damping vibration or changing bandwidth. The manufacturer also provides a servo multi-disc clutch Radex NC for customers to choose. If the customer’s requirements for robustness are relatively high, this clutch can be selected.

The choice of cutting tools and the determination of cutting amount in CNC machining The choice of cutting tools and the determination of the cutting amount are important contents in the CNC machining process. It not only affects the machining efficiency of the CNC machine tool, but also directly affects the machining quality. Development of CAD / CAM technology The exhibition makes it possible to directly use CAD design data in CNC machining, especially the connection between the microcomputer and the CNC machine tool, so that the entire process of design, process planning and programming is completed on the computer,
