Wire cutting machine operation method:

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…

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…

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…

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…

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…

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…

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…

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…

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…
