Hydraulic breakers are already an important part of hydraulic excavators. The power source of the hydraulic breaker is the pressure oil supplied by the pump station of the excavator or loader. The hydraulic breaker mainly consists of piston....
Compared with ordinary CNC lathes, the turning turret of the turning center is equipped with a power tool that can rotate the milling cutter, the drill bit and the tap. At the same time, the machine spindle also has a C-axis function that c....
Definition of cold extrusion: extrusion at a temperature below the recovery temperature. For most non-ferrous metals such as aluminum, copper, titanium, and steel materials, it generally refers to extrusion at room temperature. Cold extrusi....
The traditional method of threading is mainly to use a forming tool or a grinding tool to machine a thread on a workpiece. There are mainly turning, milling, tapping, wire grinding, grinding and cyclone cutting. When turning, milling and gr....
The roller is the main part on the rolling mill. In the actual use process, due to a certain impact force, and the surface will be rubbed by high-speed, high-temperature red steel. The surface is required to have good wear resistance, and a....
Ultra-hard turning is defined as the machining process for turning workpieces with high hardness materials above HRC45. Generally, the hardness of the workpiece material can reach the range of HRC 58-68, and the material of the cutting tool ....
Typically said processing hardness exceeds 56HRC, or strength exceeds Rm steel materials 2000N / mm2 for hard machining. In most cases, the mold or forging die is subjected to carburizing or quenching after pre-machining. After pre-machining....
The specifications of printed circuit boards are complex and there are many types of products. The most widely used epoxy resin-based composite material in printed circuit boards is a micro hole (a small hole with a diameter of 0.6 mm or les....
During the machining process of engine and transmission parts, current process control measures cannot meet the hole machining requirements. The cause of failure is often caused by some failure modes of the machined hole. The distortion of....
Composite machining is the implementation of several different machining processes on one machine that is an advanced manufacturing technology. Turning and milling combined machining is the most difficult composite machining. It is equivale....
