Ultra-precision machining technology is an important way to improve the performance, quality, service life and reliability of electromechanical products, as well as saving materials and energy. For example: improving the machining accuracy of cylinders and pistons can improve the efficiency and horsepower of automobile engines and reduce fuel consumption; improving the machining accuracy of rolling elements and raceways of rolling bearings can increase the speed of bearings, reduce vibration and noise; improve flatness of processing of magnetic disks, thereby reducing the gap between it and the magnetic head, can greatly increase the storage capacity of the magnetic disk; improving the marking accuracy of the semiconductor device (reducing the line width, increasing the density) can improve the integration of the microelectronic chip, etc.
Honing is a common procedure, similar to grinding, which is a used on the inside surface of a cylinder, tube, or bore hole after precision machining and grinding. It is performed as a final procedure after grinding, to attain a precise shape and high-quality surface finish on a workpiece.
Titanium alloys are widely used in aerospace, chemical, marine, and automotive industries due to their excellent strength-to-weight ratio, corrosion resistance, and ability to maintain strength at high temperatures. However, the disadvantages of titanium alloys are poor thermal conductivity and strong reactivity with tool materials. Their high strength, and low elastic modulus make them difficult to cut materials.
Aerospace components must guarantee personnel safety and facilitate the optimal performance of high-precision instruments and machines.
In the field of manufacturing processing, common processing methods include broaching, boring, grinding, milling, etc.
Stamping is a process in which thin walled metal parts are shaped by punches and dies.
