Strategies for high-speed roughing and finishing of graphite electrodes are different. Generally rough machining should leave less allowance for finishing, so when using small diameter tools, high feeds (cutting and feed) should be used. On....
A large number of integral thin-walled structural parts are used in the modern aviation industry. Its main structure consists of side walls and webs. Because of its simple structure, large size and large machining allowance. The relative ri....
In the past few years, high speed milling has been used as an alternative and complement to conventional milling or electrical discharge machining. High-speed milling firmly establishes the status of keeping pace with traditional machining....
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....
Hard and brittle materials such as glass, ceramics, and hard alloys are difficult to process by conventional methods. However, if high-frequency vibration is added during the traditional milling, drilling, and grinding processes, that is, c....
In the towed concrete pump truck, there is a typical large diameter thin walled part - the intermediate sleeve. The inner hole has a diameter of 202 mm, an outer diameter of 212 mm, and a wall thickness of only 5 mm. Moreover, the positiona....
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 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....
Large area PCD articles are polished by conventional mechanical polishing. The grinding wheel will first contact the convex portion which appears due to stress deformation, resulting in defects such as long polishing time and local thicknes....
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 ....
