Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

A well-designed engine oil filtration system is closely related to the service life of the oil

 

Some industrial engines are designed to use gaseous fuels (such as natural gas). Although this type of engine is similar to a diesel engine, it has been improved so that the combustion reaction in the cylinder is started by electric sparks. This is different from a real diesel engine. Industrial diesel engines in actual use are equipped with reciprocating pistons. Diesel engines can be either two-stroke or four-stroke. According to the arrangement of cylinders, fuel engines can be divided into vertical, horizontal or with a certain inclination, such as V-shaped engines. The type of engine used in the industry depends on the requirements for engine power, weight and size. The main function of engine oil in the engine is to reduce friction, absorb frictional heat, and cool the engine.

In order to meet the design requirements of different types of engines, a series of engine oils with viscosity and quality grades have been developed. In order to reduce the formation of deposits and coke, all engine oils must have good thermal oxidation stability to extend the oil drain period. A well-designed engine oil filtration system is also closely related to the service life of the oil. In addition to reducing friction, the oil also has the function of removing metal wear particles between the fine gaps on the moving surface and keeping it clean. The products of the combustion of wear particles and fuel must remain suspended in the oil in order to be filtered out by the engine oil filter device. The operating conditions of the diesel engine are variable, including low-speed stable output, medium-speed variable output, high-speed and high-output. Because the cleanliness of the oil plays an important role in the engine, the oil must contain a detergent and dispersant. Engines with high compression ratios have a tendency to accelerate the formation of oil precipitation. Engine oil with high-definition cleanliness can keep the piston clean, reduce the rate of wear between the cylinder and the piston ring, and prolong the service life of the engine. Detergents can prevent decomposition products from depositing on piston rings, pumping paths and other components. Oil temperature has a significant effect on dispersion, and it is difficult to achieve good dispersion effect at low temperature, but for diesel engine crankcase oil with high power output, low temperature dispersion is often the most basic requirement.
