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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

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

Skilled driving skills can effectively reduce tire wear

The driving method of a car has a lot to do with tire wear. Good and skilled driving skills can effectively reduce tire wear, extend the service life of tires, and improve driving safety.
1. Do not start too hard to avoid acceleration of tread wear due to the drag of the tires and the ground; 2. When the vehicle goes downhill, you should control the appropriate speed according to the size, length and road conditions of the slope, so as to avoid or use less emergency braking To reduce tire wear;
3. Vehicle turning should be decelerated appropriately according to the conditions of the curve and the turning radius, so as not to accelerate unilateral tire wear due to inertial force and centrifugal force;
Fourth, when driving on uneven roads, one must choose the road surface to reduce the collision between the tire and the road surface to avoid damage to the parts and tires, and the other is to slow down to avoid tire bumps and strong vibration;
5. When turning, overtaking, passing through intersections, narrow roads, railway crossings, etc., you should master the appropriate speed and pay attention to the road surface, pedestrians, and vehicle dynamics, prepare for braking, reduce frequent braking, and avoid emergencies Braking, thereby reducing tire wear;
6. When driving in the highway maintenance and construction section, use the method of low speed and slow driving to choose the road to pass, so as to avoid excessive impact on the tires, or even stab or scratches;
7. Passing through muddy areas, you should choose a relatively solid and non-slip place to pass, so as to prevent tires from sinking, idling in place, and severe vibrations causing serious cuts and scratches on the tires and sidewalls; 8. Vehicles stopping and stopping during driving , Should develop the habit of sliding safely.
